SAFETY PRECAUTIONS
MAINTENANCE AND REPAIR
• The Service Manuals are updated on a regular basis, but may not reflect recent design changes to the prod-
uct. Updated technical service information may be available from your local authorized Hyster® dealer. Service
Manuals provide general guidelines for maintenance and service and are intended for use by trained and expe-
rienced technicians. Failure to properly maintain equipment or to follow instructions contained in the Service
Manual could result in damage to the products, personal injury, property damage or death.
• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fastened, and that the load
being lifted is balanced. Make sure the crane, cables, and chains have the capacity to support the weight of the
load.
• Do not lift heavy parts by hand, use a lifting mechanism.
• Wear safety glasses.
• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on electric lift trucks.
Disconnect the battery ground cable on internal combustion lift trucks.
• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE LIFT TRUCK ON
BLOCKS in the Operating Manual or the Periodic Maintenance section.
• Keep the unit clean and the working area clean and orderly.
• Use the correct tools for the job.
• Keep the tools clean and in good condition.
• Always use HYSTER APPROVED parts when making repairs. Replacement parts must meet or exceed the
specifications of the original equipment manufacturer.
• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to remove parts.
• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or if the unit needs
repairs.
• Be sure to follow the WARNING and CAUTION notes in the instructions.
• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are flammable. Be sure
to follow the necessary safety precautions when handling these fuels and when working on these fuel systems.
• Batteries generate flammable gas when they are being charged. Keep fire and sparks away from the area. Make
sure the area is well ventilated.
NOTE: The following symbols and words indicate safety information in this
manual:
WARNINGIndicates a hazardous situation which, if not avoided, could result in
death or serious injury.

General
WARNINGDO NOT make repairs or adjustments unless
you have both authorization and training. Re-
pairs and adjustments that are not correct can
make a dangerous operating condition.
WARNINGDONOT operate a lift truck that needs repairs.
Report the need for repairs immediately. If re-
pair is necessary, put a DO NOT OPERATE tag
in the operator’s area. Remove the key from
the key switch.
CAUTIONDisposal of lubricants and fluids must meet lo-
cal environmental regulations.
This section contains a Maintenance Schedule and
the instructions for maintenance and inspection.
The Maintenance Schedule has time intervals for in-
spection, lubrication, and maintenance of your lift
truck. The service intervals are provided in both op-
erating hours recorded on the lift truck hourmeter
and in calendar time. The recommendation is to use
the interval that comes first.
The recommendations for the time intervals provided
is for eight hours of operation per day. The time inter-
vals must be decreased from the recommendations
in the Maintenance Schedule for the following condi-
tions:
• The lift truck is used more than eight hours per
day.
• The lift truck must work in dirty operating condi-
tions.
• Poor ground conditions.
• Intensive usage at high performance levels or
other abnormal conditions will require more fre-
quent servicing.
Your dealer for Hyster lift trucks has the equipment
and trained service personnel to do a complete pro-
gram of inspection, lubrication, and maintenance. A
regular program of inspection, lubrication, andmain-
tenance will help your lift truck provide more effi-
cient performance and operate for a longer period of
time.
Some users have service personnel and equipment
to do the inspection, lubrication, and maintenance
shown in the Maintenance Schedule. Service man-
uals are available from your dealer for Hyster lift
trucks to help users who do their own maintenance.
SERIAL NUMBER DATA
The serial number for the lift truck is on the Name-
plate. It is also on the right side of the frame, under
the floor plate.

HOW TO MOVE DISABLED LIFT TRUCK
How to Tow Lift Truck
WARNINGUse extra caution when towing a lift truck if
any of the following conditions exist:
• Brakes do not operate correctly.
• Steering does not operate correctly.
• Tires are damaged.
• Traction conditions are bad.
• The lift truck must be towed on a slope.
If the engine cannot run, there is no power
available for the hydraulic steering system
and the service brakes. This condition can
make the lift truck difficult to steer and stop.
If the lift truck uses power from the engine to
help apply the brakes, the application of the
brakes will be more difficult. Poor traction can
cause the disabled lift truck or towing vehicle
to slide. A slope will also make the lift truck
more difficult to stop.
Never lift and move a disabled lift truck unless
the disabled lift truck MUST be moved and
cannot be towed. A lift truck used to move
a disabled lift truck MUST have a capacity
rating equal to or greater than the weight of
the disabled lift truck. The capacity of the lift
truck used to move a disabled lift truck must
have a load center equal to half the width of
the disabled lift truck. See the Nameplate of
the disabled lift truck for the approximate
total weight. The forks must extend the full
width of the disabled lift truck. Put the weight
center of the disabled lift truck on load center
of the forks. Be careful to not damage the
underside of the lift truck.
1. The towed lift truck must have an operator.
2. Tow truck slowly.
3. Using a lift truck or a lifting device that could
be attached to the mast (I.E. come-a-long), raise
carriage and forks approximately 30 cm (12 in.)
from surface. Install chain around a mast cross-
member and carriage to prevent carriage and
mast channels from moving.
4. If another lift truck is used to tow the disabled lift
truck, that lift truckmust have an equal or larger
capacity than the disabled lift truck. Install ap-
proximately 1/2 of a capacity load on forks of lift
truck that is being used to tow disabled lift truck.
This 1/2 capacity load will increase traction of lift
truck. Keep load as low as possible.
5. Use a towing link made of steel that fastens to
tow pins in counterweights of both lift trucks.
Slowly and carefully remove the slack out of the
towing link. See Figure 1.

HOW TO PUT LIFT TRUCK ON BLOCKS
How to Raise Drive Tires
WARNINGThe lift truck must be put on blocks for some
types of maintenance and repair. The removal
of the following assemblies will cause large
changes in the center of gravity: mast, drive
axle, engine, transmission, and counterweight.
When the lift truck is put on blocks, put ad-
ditional blocks in the following positions to
maintain stability:
• Before removing the mast and drive axle, put
blocks under the counterweight so the lift
truck cannot fall backward.
• Before removing the counterweight, put
blocks under the mast assembly so the lift
truck cannot fall forward.
The surfacemust be solid, even, and level when
the lift truck is put on blocks. Make sure any
blocks used to support the lift truck are solid,
one-piece units.
CAUTIONThese lift trucks are equipped with cowl lifting
eyes. The cowl lifting eyes are to be used to
lift the front of the lift truck only. Lifting more
than the front of the lift truck with the cowl
lifting eyes will damage the cowl section.
1. Put blocks on each side (front and back) of steer-
ing tires to prevent movement of lift truck. See
Figure 2.
2. Put mast in vertical position. Put a block under
each outer mast channel.
3. Tiltmast fully forward until drive tires are raised
from surface.
4. Put additional blocks under frame behind drive
tires.
5. If hydraulic system will not operate, use a hy-
draulic jack under the side of the frame near the
front. Make sure jack has a capacity equal to at
least half the weight of the lift truck. See Name-
plate.
How to Raise Steering Tires
NOTE: Some lift trucks are equipped with lifting eyes
for the purpose of lifting the entire lift truck. If lift
truck is equipped with these type of lifting eyes, the
lift truck can be lifted and blocks installed.
1. Apply parking brake. Put blocks on both sides
(front and back) of drive tires to prevent move-
ment of lift truck. See Figure 2.
2. Use hydraulic jack to raise steering tires. Make
sure jack has a capacity of at least 2/3 of total
weight of lift truck as shown on the Nameplate.
3. Put jack under steering axle or frame to raise
lift truck. Put blocks under frame to support lift
truck.

HOW TO CLEAN A LIFT TRUCK
WARNINGEngine, exhaust system components and other
components are hot to the touch. Be sure lift
truck components are cool before starting in-
spection and cleaning, or personal injury may
occur.
WARNINGCompressed air canmove particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel. Wear protective
goggles or a face shield to prevent injury to the
eyes.
CAUTIONUnits may be washed with a non-heated pres-
sure washer. Steam cleaning is not recom-
mended in most instances, as condensation
may form in electrical components causing
damage or erratic behavior.
NOTE: Lift trucks used in paper applications may
need cleaning beyond what is described here. Please
refer to Paper Application section in the applicable
Operating Manual and to available Service Gram/
Bulletin for more detail.
If it becomes necessary to clean the fork lift, follow
the guidelines listed below.
1. Assure truck components are cool before starting
the cleaning procedure.
2. Disconnect the battery. If an electric truck, re-
move the traction battery.
3. Remove accumulated debris using a compressed
air line and nozzle.
4. Lightly spray a non-corrosive cleaning agent onto
the areas to be cleaned. This will help loosen
grime, so close contact direct spraying will not be
necessary.
5. Be sure to avoid directing the spray into electri-
cal panel compartment. Ensure overspray does
not come in contact with electrical components;
do not spray water directly at electrical compo-
nents, wiring connectors or electrical enclosures.
Even sealed connectors may allow water egress
under pressure or if connector is damaged.

8000 SRM 1150 Maintenance Schedule
6. Avoid spraying in areas containing electrical
components such as:
• Floor Plates
• Battery Compartment
• Dash/cowl assembly
• Armrests with electrical components
7. Clean the battery compartment by using a clean
cloth to wash the battery with water. Dry with
compressed air. Care should be taken to keep
moisture at a minimum as some units have a
traction or hydraulic motor directly below the
battery compartment.
8. DO NOT pressure wash the battery. Do not use
hot water. For cleaning traction batteries, refer
to the Battery section of the Service Manual.
9. DO NOT pressure wash lift chains, sheaves or
load rollers in the mast assembly. Refer to the
Chains, Sheaves and Load Rollers maintenance
section in the Service Manual for proper clean-
ing procedures.
10. After cleaning, immediately start and run the lift
truck to dry out components.

NOTE 5: Recommended service intervals are based on a normal application in a clean environment. Applications in-
volving contaminated environments such as high levels of air borne debris (dust and waste paper); chemical or abrasive
compounds; poor ground conditions; intensive usage at high performance levels; or other abnormal conditions will require
more frequent servicing. At your request your Hyster dealer will advise you of the appropriate service intervals based on
an application survey.
NOTE 6: In dirty or dusty environments, replace at 1000 hours or as needed.
NOTE 7: Replace timing belt on Mazda engines every 3500 hours. Use only hour interval.
NOTE 8: Check fuel injectors at 5000 hours or 7 years.
NOTE 9: Multipurpose grease with 2 to 4% Molybdenum Disulfide.
NOTE 10: Vehicles used in paper application require regular inspection and cleaning to minimize risk of fire. This should
be done at least once every 8 hours or more frequently, depending upon operating environment. Use compressed air and
steam clean as necessary.
NOTE 11: Lubricate mast every three months if unit has less than 1000 hours.
NOTE 12: Lubricate at first sign of visible surface rust.
NOTE 13: Do not open the air filter canister except to change the air filter element. See Maintenance Procedures Every
2000 Hours or Annually to change air filter element.
NOTE 14: Replace after 3000 hours. Use hour interval only.
NOTE 15: Use Ethylene Glycol Boron-free Antifreeze. Purchase a pre-diluted 50/50 solution; or mix 50% concentrate with
50% distilled water or deionized water.
NOTE 16: Hydraulic oil sampling and analysis is a recommended practice. See Hydraulic Cleanliness Procedures
1900 SRM 1620 for oil cleanliness and water content guidelines. For lift trucks operating in heavy duty applications or
highly contaminated environments, take oil samples every 500 hours. Normal Operating conditions may allow for less
frequent oil sampling. Oil sampling should be done just prior to all oil and filter changes.

Maintenance Procedures Every 8 Hours or Daily
HOW TO MAKE CHECKS WITH ENGINE
STOPPED
WARNINGDONOT operate a lift truck that needs repairs.
Report the need for repairs immediately. If
repair is necessary, put a DO NOT OPERATE
tag in the operator’s area. If the lift truck is
equipped with a key switch, remove the key
from the key switch.
Put lift truck on a level surface. Lower carriage
and forks, stop the engine, and apply parking brake.
Open hood and check for leaks and conditions that
are not normal. Clean any oil or fuel spills. Ensure
all surfaces are free of oils, lubricants, fuel, and or-
ganic dust or fibers (paper, wood, cotton, agricultural
grass/grain, etc.).
Tires and Wheels
Check tires for damage. Check tread and remove any
objects that will cause damage. Check for bent or
damaged rims. Check for loose or missing hardware.
Remove any wire, strapping, or other material that
is wrapped around the axle. See Figure 17.
Safety Labels
WARNINGSafety labels are installed on the lift truck to
provide information about operation and pos-
sible hazards. It is important that all safety la-
bels are installed on the lift truck and can be
read.
Check that all safety labels are installed in the cor-
rect location on lift truck. See the Parts Manual,
Model Description section in theOperatingMan-
ual or section Frame 100 SRM 1120 for correct lo-
cation of safety labels. See Parts Manual for part
numbers of the safety labels.

8000 SRM 1150 Maintenance Procedures Every 8 Hours or Daily
Mast, Carriage, Lift Chains, Header Hoses,
Attachment
WARNINGLower the lift mechanism completely. Never
allow any person under a raised carriage. DO
NOT put any part of your body in or through
the lift mechanism unless all parts of the mast
are completely lowered and the engine is
STOPPED. DO NOT try to correct the align-
ment of the fork tips by bending the forks or
adding shims. Never repair damaged forks by
heating or welding. Forks are made of special
steel using special procedures. If either fork is
damaged, replace the forks as a set.
1. Inspect welds on mast and carriage for cracks.
Make sure that capscrews and nuts are tight.
2. Inspect channels for wear in areas where the
rollers travel. Inspect rollers for wear or dam-
age.
3. Inspect load backrest extension for cracks and
damage.
4. If lift truck is equipped with an integral sideshift
carriage or attachment, inspect the parts for
cracks and wear. Make sure the parts that fas-
ten the integral sideshift carriage or attachment
to carriage are in good condition.
5. Visually inspect hoses/fittings for hydraulic
leaks; hose cover for cuts, cracks or exposed re-
inforcement; defective/broken clamping devices
or sheaves; proper tracking during operation.
Adjust/repair/replace hose/components as nec-
essary. See Mast Repairs, 2-, 3-, and 4-Stage
Masts 4000 SRM 1148 for quick disconnect pro-
cedures.
6. Check that lift chains are correctly lubricated.
Use SAE 30W engine oil as necessary to lubricate
lift chains.
7. Inspect lift chains for cracks or broken links, and
worn or turned pins. See Figure 18.
8. Inspect chain anchors and pins for cracks and
damage.
9. Make sure lift chains are adjusted so that they
have equal tension. Adjustments or replace-
ment of the lift chains must be done by au-
thorized personnel.

Operator Restraint System
NOTE: The seat belt can be either black or red.
The seat belt, hip restraint, seat, hood, and hood
latch are all part of the operator restraint system.
Each item must be checked to make sure it is fas-
tened correctly, functions correctly, and is in good
condition. See Figure 19.
Automatic Locking Retractor (ALR)
NOTE: S40-70FT, S55FTS (F187) lift trucks produced
before November 2005 are equipped with the ALR
type seat belts.
The seat belt must fasten securely. Make sure the
seat belt extends and retracts smoothly and is not
frayed or torn. If the seat belt is damaged or does not
operate properly, it must be replaced. See Figure 19.
Emergency Locking Retractor (ELR)
NOTE: Lift trucks produced after November 2005
are equipped with the Emergency Locking Retractor
(ELR) style seat belt.
When the ELR style seat belt is properly buckled
across the operator, the belt will permit slight op-
erator repositioning without activating the locking
mechanism. If truck tips, travels off a dock, or comes
to a sudden stop, the locking mechanism will be acti-
vated and hold the operator’s lower torso in the seat.
A seat belt that is damaged, worn, or does not op-
erate properly will not provide protection when it is
needed. The end of the belt must fasten correctly in
the latch. The seat belt must be in good condition.
Replace the seat belt if damage or wear is seen. See
Figure 19.
NOTE: The following seat belt operation checks must
be performed three times before replacing the seat
belt assembly.
• With the hood closed and in the locked position,
pull the seat belt slowly from the retractor assem-
bly. Make sure the seat belt pulls out and retracts
smoothly. If the seat belt cannot be pulled from the
retractor assembly or the belt will not retract, re-
place the seat belt assembly.
• With the hood closed and in the locked position,
pull the seat belt with a sudden jerk. Make sure the
seat belt will not pull from the retractor assembly.
If the seat belt can be pulled from the retractor,
when it is pulled with a sudden jerk, replace the
seat belt assembly.
• With the hood in the open position, make sure the
seat belt will not pull from the retractor assembly.
If the seat belt can be pulled from the retractor,
with the hood in the open position, replace the seat
belt assembly.
Adjust Seat - Full Suspension
Seat Position Adjustment (Standard Seat)
• Fore and aft adjustment - It is recommended that
the seat be adjusted so that the thigh is horizon-
tal to the ground in order to achieve the best er-
gonomic position. See Figure 19.
Seat Position Adjustment (Swivel Seat)
• The seat swivels 12 degrees to the right to allow the
operator a more ergonomic position when driving
in reverse.
• The seat swivels 5 degrees to the left to allow an
easier exit of the truck.
• The neutral position is shown in Figure 19.
Seat Adjustment for Operator Weight
CAUTIONAmajor cause for highWhole Body Vibration is
caused by the operator not adjusting the seat to
his/her weight.
NOTE: It is important to adjust the weight setting for
each operator.
NOTE: The seat is designed for maximum weight of
135 kg (298 lb).

8000 SRM 1150 Maintenance Procedures Every 8 Hours or Daily
Hood and Seat Latches
Make sure seat rails and latch striker are not loose.
Seat rails must lock tightly in position, but move
freely when unlocked. See Figure 19. Seat rails must
be correctly fastened to the hood and the hood fas-
tened to hinges on frame. Try to lift the hood to make
sure it is fastened correctly and will not move. If ad-
justment is required, go to Hood Latch Check.
Engine Compartment
Check for the presence of any combustible material
such as paper, leaves, etc. Remove any combustible
materials.
Paper Application
Vehicles used in paper applications require regular
inspection and cleaning to minimize the risk of fire.
This should be done at least once every eight hours
or more frequently depending upon operating en-
vironment. The paper application option will help
limit the contact of paper or tissue scraps to hot
surfaces under the hood, but frequent maintenance
is required.
WARNINGEngine and exhaust system components are
hot to touch. Be sure lift truck components are
cool before starting inspection and cleaning or
personal injury may occur.
Ensure truck engine cools properly by allowing it to
idle for several minutes. Shutting truck down while
hot will not allow engine to cool quickly due to the
loss of coolant circulation. The heat trapped under
the hood may actually increase engine temperature
because of no heat transfer through the radiator.
With engine off and lift truck components cooled,
check and clean the radiator and if equipped, radi-
ator screen. Check engine manifold, exhaust pipes,
muffler and catalytic converter for paper scraps.
Clean as required. Check and clean engine compart-
ment components, transmission, fan shroud, belly
pan if equipped, and inside frame ledges to avoid
paper, dust and oil accumulation. Check axle and
cowl openings for paper buildup and bailing wire.
Remove any debris.
WARNINGCompressed air canmove particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel. Wear protective
goggles or a face shield to prevent injury to the
eyes.
CAUTIONAir pressure, nozzle or extension tube may
cause damage to exhaust wraps and radiator
fins. Assure that air pressure, nozzle or exten-
sion tube does not damage exhaust wraps or
radiator fins.
Paper removal can generally be accomplished using a
compressed air line and nozzle. An extension may be
helpful to access hard to reach places. Remove floor
plates and side covers for better access to engine com-
partment. Open or removed belly pan, if equipped.
Clean components with compressed air. Take care
to maintain the integrity of the exhaust wraps when
cleaning with compressed air and use caution to not
force debris into openings. Check the condition of ex-
haust wraps for wear, proper fit, contamination with
oil or antifreeze, gaps in coverage, failed fasteners
and replace as necessary. Do not reuse wraps if they
have been removed for some other service operation.
WARNINGBe careful when cleaning with steam. Steam
can cause serious burns. Wear protective cloth-
ing, gloves, and eye protection. Never expose
your skin to steam.
If compressed air did not adequately remove debris,
steam clean to remove any persistent accumulation
of material or oil. Protect electrical components from
moisture when steam cleaning. Do not spray exhaust
wraps directly with high pressure steam. Allow lift
truck to air dry before returning to work in a con-
taminated environment. Paper dust and scraps will
adhere to wet surfaces.
Check the condition of exhaust wraps for wear,
proper fit, contamination with oil or antifreeze, gaps
in coverage, failed fasteners and replace as neces-
sary. Do not reuse wraps if they have been removed
for some other service operation.

Maintenance Procedures Every 8 Hours or Daily 8000 SRM 1150
Fuel, Oil, and Coolant Leaks, Check
WARNINGAll fuels are very flammable and can burn or
cause an explosion. DO NOT use an open flame
to check the fuel level or to check for leaks in
the fuel system. If there is a leak in the fuel sys-
tem, extra care must be used during the repair.
DO NOT operate the lift truck until a leak is re-
paired.
Make a visual check for leaks on and under the lift
truck. If possible, find and report leaks to mainte-
nance for repair. Leaks often indicate a need for re-
pair of damaged or worn components. Leaks in the
LPG fuel system are usually not visible unless ice
is present. There is however, usually a strong odor.
Fuel leaks MUST be repaired IMMEDIATELY.
Check fuel system for leaks and the condition of
parts. When fuel is added to lift truck, see section
HOW TO ADD FUEL TO THE LIFT TRUCK in the
Operating Manual.
Also check the condition of radiator or heater hoses
that are not leaking. Soft or cracked hoses need to be
replaced before a major leak occurs.
Hydraulic Hoses
Check condition of hydraulic hoses for serviceabil-
ity by inspecting for cracks or other obvious dam-
age. Check to ensure that the hydraulic hoses are
not leaking. If any hose is leaking, report it to main-
tenance for repair.
Coolant Hoses
Check condition of coolant hoses for serviceability by
inspecting for cracks or other obvious damage. Check
to ensure that the coolant hoses are not leaking. If
any hose is leaking, report it to maintenance for re-
pair.
Steering Column Gas Cylinder
Make sure the gas cylinder for steering column oper-
ates correctly. The cylinder must NOT allow column
to move unless tilt lever is released. See Figure 21.
Transmission
Check transmission for leaks and damaged or loose
components. Heavy-duty or high temperature oper-
ations can require more frequent checks.

Hydraulic System Oil
WARNINGAt operating temperature, the hydraulic oil is
HOT. DO NOT permit the hot oil to touch the
skin and cause a burn.
CAUTIONDO NOT permit dirt to enter the hydraulic sys-
tem when the oil level is checked or the filter
is changed.
Never operate the hydraulic pump without oil
in the hydraulic system. The operation of the
hydraulic pump without oil will damage the
pump.
After engine has stopped, wait one minute before
checking the oil level. Keep hydraulic oil at the cor-
rect level as indicated on dipstick. Use correct oil as
shown in the Maintenance Schedule.
Check hydraulic system for leaks and damaged or
loose components. Heavy-duty or high-temperature
operations can require more frequent checks.

Brake Fluid Level
WARNINGSmall amounts of water in the brake system
can cause reduced braking performance if the
water reaches the wheel cylinder areas. DO
NOT allow water entry. Ensure that the sealed
reservoir lid is properly replaced.
On lift trucks with wet brake drive axles, only
use Dexron III oil from sealed container in the
master cylinder.
On lift trucks with dry brake drive axles, only
use SAE J-1703 (DOT 3) brake fluid in the mas-
ter cylinder.
WARNINGIf the brake system has a power assist (or
boosted master cylinder), braking will be more
difficult if the engine is not running.
Loss of fluid from the brake fluid reservoir in-
dicates a leak. Repair the brake system before
using the lift truck. Replace the brake fluid in
the system if there is dirt or water in the sys-
tem.
48
8000 SRM 1150 Maintenance Procedures Every 8 Hours or Daily
There is an indicator light on the Display Switch
Cluster for the brake fluid. The red light is ON
when the key switch is in the START position or
the Power ON/OFF button is pressed, and must go
OFF when the engine is running. If the light is on
when the engine is running, the brake fluid level in
the reservoir is too low.
Operation, Check
Check the operation of the service brakes. Push on
the inching/brake pedal. The service brakes must be
applied before the inching/brake pedal reaches the
floor plate. The pedal must stop firmly and must
not move slowly down after the brakes are applied.
The service brakes must apply equally to both drive
wheels. The service brakes must not pull the lift
truck to either side of the direction of travel when
they are applied. The service brakes are automat-
ically adjusted when the transmission is in reverse
and the lift truck is moving and the brakes are firmly
applied. Full application of the inching/brake pedal
applies the service brakes and puts the transmission
in NEUTRAL.
Lift trucks with a MONOTROL® pedal. When
the inching/brake pedal is fully applied, a switch in
the starting circuit is closed so that the engine can be
started.
Parking Brake
Make sure service brakes are adjusted and the oper-
ation of the automatic adjuster mechanism is correct
before parking brake is adjusted.
Lift trucks with a MONOTROL® pedal. The
switch energizes the seat warning circuit when hand
lever is released. This switch puts the transmis-
sion in NEUTRAL by de-energizing the direction
solenoid. There is also a switch on the left side of
bracket. This switch prevents engine from starting
unless parking brake is applied.
NOTE: Make sure parking brake is released before
making adjustment.
1. Turn adjustment knob to raise the equalized link
and tighten parking brake cables shown in Fig-
ure 33. DO NOT tighten the adjustment so that
brake is applied when the lever is released. The
lever for the parking brake has a lock. Use your
thumb or finger to release lock on lever when
parking brake is released.
2. For burnished brakes, test the operation of the
parking brake. The lift truck with a capacity load
must not move when parking brake is applied on
a 15 percent grade [a slope that increases 1.5 m
in 10 m (1.5 ft in 10 ft)].

with a key switch, or when the power ON/OFF but-
ton is pressed, if the truck is equipped with this op-
tion, and will stay illuminated until correct oil pres-
sure is obtained, at which time the light will go off.
If the light continues to stay on when engine is run-
ning, the engine oil pressure is low. Stop the engine
and check the oil level. Do not restart the engine un-
til the low pressure condition has been corrected.

Cooling System
WARNINGDONOT remove the radiator cap from the radi-
ator when the engine is hot. When the radiator
cap is removed, the pressure is released from
the system. If the system is hot, the steam and
boiling coolant can cause burns.
NOTE: The engine will enter shutdown mode after a
warning buzzer sounds and a 30-second countdown,
if coolant temperature reaches 121°C (250°F) or
above on lift trucks with powertrain protection sys-
tem and a Mazda engine. Lift trucks equipped with
a Yanmar diesel engine will enter shutdown mode
when coolant temperature reaches 110°C (230°F)
or above on lift trucks with powertrain protection
system. See ENGINE SHUTDOWN procedures in
the Operating Manual.
There is an indicator light on the Display Switch
Cluster for the coolant temperature. The red light
is on when key switch is in the START position or
the Power ON/OFF button is pressed, and must go
off when the engine is running. If light is on when
engine is running, the coolant and engine are too hot.
Stop engine and check coolant level in the coolant
recovery reservoir.
Make sure coolant level is between the ADD and
FULL marks on the auxiliary coolant reservoir. See
Figure 34. The coolant will expand as it is heated
and the level in the auxiliary coolant reservoir will
increase.
CAUTIONAdditives may damage the cooling system. Be-
fore using additives, contact your local Hyster
dealer.
If coolant is added, seeMaintenance Schedule for cor-
rect solution.
WARNINGCompressed air canmove particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel. Wear protective
goggles or a face shield to prevent injury to the
eyes.
Check the radiator fins. Turn engine OFF and clean
the radiator with compressed air or water as needed.

LIFT CHAINS WEAR CHECK
If a section of chain is 3% longer than a similar sec-
tion of new chain, the chain is worn and must be re-
placed. Measure chain for wear where it moves over
sheaves. Using a chain scale, (Hyster P/N 871796)
check lift chains as shown in Figure 72.
LIFT CHAIN LUBRICATION
WARNINGCleaning solvents can be flammable and toxic
and can cause skin irritation. When using
cleaning solvents, always follow the recom-
mendations of the manufacturer.
Compressed air can move particles so they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel. Wear protective
goggles or a face shield to prevent injury to
the eyes.
Remove the lift chains. Clean the lift chains by soak-
ing them in a solvent that has a petroleum base for
at least 30 minutes. Use compressed air, adjusted to
a maximum output of 103 kPa (15 psi), to completely
dry the chains when they are clean.
Lubricate the lift chains by soaking them in 30W en-
gine oil for at least 30 minutes. Remove the chains
from the oil. Hang the chains for one hour so excess
oil will drain from the chains.

ement, press and rotate filter element counter-
clockwise about 1/8 turn until the filter element
is free. To assist removal, gently move the end
back and forth to help break the seal. See Fig-
ure 78.
3. Gently pull the filter element from the canister.
Avoid dislodging contaminants from the element
or knocking it against the canister.
4. With a clean, soft rag, clean the inside surface
of the canister. Remove liner assembly to make
cleaning easier. Clean well around the locking
tabs that retain the element. Clean tabs make
new filter element installation easier. Be careful
not to knock any contaminants into the outlet
tube to the engine.
5. Inspect liner and O-ring assembly for damage. If
damaged, replace liner and O-ring assembly.
6. Install liner assembly into canister by pushing
in. Make sure liner assembly is properly seated
in the canister. It will fit snugly into and be cen-
tered in the canister.
If your air filter assembly is equipped with a sec-
ondary element in place of the liner assembly, re-
place the secondary element with every 2 to 3 pri-
mary element replacements.
7. Inspect the new filter element for voids, cuts,
tears or indentations in the urethane-sealing
surfaces. Do not use if damage is detected.

The following proceduresmust be usedwhen inspect-
ing or working near themast. Additional precautions
and procedures can be required when repairing or re-
moving themast. See the correct ServiceManual sec-
tion for the specific mast being repaired.
WARNINGMast parts are heavy and can move. Distances
between parts are small. Serious injury or
death can result if part of the body is hit by
parts of the mast or the carriage.
• Never put any part of the body into or under
the mast or carriage unless all parts of the
mast are completely lowered or a safety chain
is installed. Also make sure that the power is
off and the key is removed. Put aDONOTOP-
ERATE tag in the operator’s compartment.
• Be careful of the forks. When the mast is
raised, the forks can be at a height to cause
an injury.
• DO NOT climb on themast or lift truck at any
time. Use a ladder or personnel lift to work
on the mast.
• DO NOT use blocks to support the mast weld-
ments nor to restrain their movement.
• Mast repairs require disassembly and re-
moval of parts and can require removal of
the mast or carriage. Follow the repair pro-
cedures in the correct Service Manual for
the mast.
NOTE: If there is no power to lower the mast on lift
trucks equipped with Electronic Hydraulic System,
there is an emergency load lowering valve located
on the hoist/lower valve section of the main control
valve. See the Operating Manual for the proce-
dures to lower a load using the emergency load low-
ering valve.
1. Lower mast and carriage completely. Push lift/
lower control lever forward and make sure there
is no movement in the mast. Make sure all parts
of the mast that move are fully lowered.
OR
2. If parts of the mast must be in a raised position,
install a safety chain to restrain themoving parts
of the mast. Connect moving parts to a part that
does not move. Follow these procedures:
a. Put mast in vertical position.
b. Raise mast to align bottom crossmember
of weldment that moves in outer weldment
with a crossmember on outer weldment.
On the two-stage and free-lift mast, the
moving part is the inner weldment. On
the three-stage mast, it is the intermediate
weldment. See Figure 100.
c. Use a 3/8-in. minimum safety chain with a
hook to fasten the crossmembers together so
the movable member cannot lower. Put the
hook on the back side of the mast. Make sure
the hook is completely engaged with a link in
the chain. Make sure the safety chain does
not touch lift chains or chain sheaves, tubes,
hoses, fittings, or other parts on the mast.
d. Lower the mast until there is tension in the
safety chain and the free-lift cylinder (free-
lift, three-stage, and four-stage masts only)
is completely retracted. If running, stop en-
gine. Apply parking brake. Install a DO
NOT REMOVE tag on the safety chain(s).
e. Install another safety chain (3/8-in. mini-
mum) between the top or bottom crossmem-
ber of the carriage and a crossmember on the
outer weldment.
3. Apply parking brake. After lowering or restrain-
ing the mast, shut off power and remove key. Put
aDONOTOPERATE tag in the operator’s com-
partment.
