TB 37Things to check before adjusting drive controller:
Check engine rpm’s for correct settings. Pump performance and Drive speeds will be greatly effected if engine rpm’s are not set correctly.
Check pressures on the variable displacement pump compensator. Main system pressure is 2800 psi and differential pressure is 300. Drive speeds can be greatly
effected if differential pressure setting on the pump compensator is incorrect.
Check the stroke limiter on the backside of pump to see that it measures 11/16's of
an inch including the jam nut. Not having the stroke limiter set correctly will cause drive speeds to be extremely slow and cause poor drive performance problems when
trying to climb an incline.

TB 42 – 50
Things to check before adjusting Drive Controller:
Check engine rpm’s for correct settings. Drive speeds will be greatly effected if engine rpm’sare not set correctly.
Check pressures on the pump compensator. Main system pressure is 2500 psi and
stand-by pressure is between 300 – 400 psi. Drive speeds can be greatly effected if
stand-by pressure setting on the pump compensator is incorrect.
Check the stroke limiter on the backside of pump to see that there is 11/16's of an inch
of the adjusting screw showing including the jam nut. Turning this adjustment out more
than 11/16's of an inch will cause the engine to bog down or in too far will starve the
drive system of flow.

Universal OEM Circuit Board Adjustments
The new universal circuit board has a trim pot adjustment for each direction of
handle movement that corresponds to the “A” or “B” connections on the circuit
board terminal strip. (“A” , wire number 17 Forward Drive or “B”, wire number 18
Reverse Drive) The “Ramp” adjustment is for either direction of handle movement
and turns off when controller hand is returned to center. Each trim pot has approximately 20 full turns of adjustment. Turning the trim pots CW will increase
voltage for that direction and turning them CCW will decrease voltage for that
direction. The following procedure will describe how to pre-set and make final
adjustment to circuit board.

The potentiometer regulates the voltage to the “A or B” terminals of the circuit board.
Moving the joystick handle forward will increase voltage and moving it reverse will decrease voltage. To check the potentiometer for center, place the positive lead of your
meter on the “Green” wire and put the black lead of your meter to a good machine
ground. With the controller in the neutral position you should read approximately .20
volts. Moving the controller handle to the full on forward position you should read .35
volts, and moving the controller handle to the full reverse position you should read .05 volts.

Preset Procedure for Drive Controller:
1. Turn the Ramp trim pot 20 full turns (CCW).
2. Turn the “A and B” Low Range Trim Pots CW 10 full turns.3. Place the ignition switch to on and start the engine. If machine is equipped with a Jib,
fully lower the Jib. Place the boom in its fully stowed position and fully Retract the
boom in. Turn engine off, turn key switch back on.
4. Place Drive Range switch set to Hi and Foot switch down.
5. Move the control handle off center approximately 1½”. 6. Holding that position, adjust the “Threshold for that direction “A or B” trim pots counter
CW to obtain 2.5 to 3.5 volts. Return controller handle to center.
Verify there is 12 volt on the “R”.
1. Depress the foot switch.2. Move the controller handle full on.
3. With the controller full on, adjust the “A and B” trim pots CW to obtain 7.5 to 9 volt
setting. Return controller handle to center.
Start engine and raise the boom up above horizontal. Turn engine off, and key switch back
on.
Verify there is “No” voltage on the “R” .
1. Depress the foot switch.2. Move the controller handle full on.
3. With the controller full on, Adjust the “A and B” Low Range trim pot clock wise or CCW
to obtain 4.5 to 5.5 volt setting. Return controller handle to center.
14
Drive Controller Final Adjustment:
Before starting controller adjustment, make sure that the hydraulic oil is up to operating
temperature 80°to 90°.
Mark off fifty feet. At the platform, place the Range Selector switch to “Hi”, Ignition switch on,
Throttle switch to HI. Make sure that the “R” terminal on the drive circuit board has 12 volts on
it. Start engine. Lower the boom below horizontal, lower jib boom to its stowed position and
fully retracted the boom. At a rolling start, perform the following:
Threshold: Make sure after the “A (Forward) and B (Reverse)” Hi and Low range has been
adjusted that the Threshold “A and B” both smooth starts and stops. (With controller handle
full on, move controller handle approximately 1” from full on towards the off position. The drive
function should start to slow down until handle reached approximately 1½” to center of controller or shuts off.)
See Drive Speed Chart below. Speed is achieved by adjusting the Hi and Low trim pots.3 MPH = 50’ in X Seconds (see chart, page 14)1 MPH = 50’ in X seconds (see chart, page 14)
High Range: Move the controller handle to the full on position. At a rolling start, time the
machine within the fifty feet. Adjust the Hi Range ”A (Forward) and B (Reverse)” trim pot
clockwise or counter clockwise as necessary to obtain the correct times as specified in the chart below.
Low Range or Dual Range: Elevate the boom above horizontal. Check the “R” terminal of
the drive controller to see that it does not have 12 volts on it. Move the controller handle to the
full on position. At a rolling start, time the machine within the fifty feet. Adjust the Low Range “A and B” trim pot clockwise or counter clockwise as necessary to obtain the correct times for
Forward (A) and Reverse (B) as specified in the chart below. After the Low Range adjustment,
lower the boom to its stowed position.
Ramp (Single Trim Pot): Is a time delay built into the circuit board for either the “A or B”direction. The more you turn the ramp trim pot clockwise, the more time delay you add to the
machine response to controller movement. Turning the ramp trim pot counter clockwise de-
creases ramp delay of controller response when moved. Adjust the ramp delay to achieve a 1
½ to 2 second delay.

The Spool Flow Stop Adjustments shown above, are located inside of each Manual Over Ride
lever of the Hawe Proportional Control Valve. Before making any adjustments of the spool flow stop, verify the speeds by operating the lift and swing functions from the ground controls. When
verifying the drive speeds, mark off 50 feet, and at a rolling start time drive within the 50 feet
from the platform. Boom Lift UP / Down (Full Stowed boom to Full Elevated or Full Elevated boom to Full Stowed ) 40 to 45 seconds Swing CW / CCW (full rotation 360°) 60 to 65 seconds

NOTE: Adjustment of the Lift / Swing Spool Stops should only be done if one direction is moving faster than the other. Timing the unite from the ground control
station will determine if an adjustment will be required. If an adjustment is required
for the Lift or Swing Spool Stops, you will need two metric hex-keys, one 2mm and
one 2.5mm. (see above pictures for locations)
1. Loosen the Spool Stop Set screw located on the L. H. or R. H. side of each manual over ride for the section to be adjusted using a 2mm hex-key. (see above
pictures for locations)
2. This step will require a second person. Start engine form the ground control
station and activate the system enable switch. Using a 35mm bolt approximately 2-
3” long or a punch of approximately the same diameter and length, insert bolt into Manual Over Ride Actuating Bolt Hole. (see above picture) Facing the control
valve, and moving the manual over ride lever to the left or the right will make the
valve respond as follows:
Moving the Manual Over Ride to the Left: Swing CCW, Boom UP, and Drive FWD
Moving the Manual Over Ride to the Right: Swing CW, Boom Down, and Drive Reverse
3. Move the manual over ride in the slower direction. Using a 2.5mm hex-key,
turning the hex screw in or CW will decrease spool movement for slower speed,
turning the hex screw out or CCW will increase spool movement for faster speed. Only move the hex screw 1/8 to 1/4 “ at a time. Re-check the time of the slower
function to see if the speed has increased to equal the faster direction. If not repeat
step 3. If speeds are now approximately the same, re-tighten the spool stop set
screw.

Final Adjustment for Swing / Lift Controller:1.Start the engine.2.Operate the controller and adjust the threshold trim pot as necessary to produce smooth
starts and stops with a minimum dead band.
Note: The LED’s must come on before motion starts and must still be on after motion
stops.
1.Move controller to full on and check for maximum speed in seconds per the chart.
Note: If the speed listed can not be obtained with the controller handle full on, increase
the high range voltage. If an increase in output voltage occurs with no increase in speed or
the function speed is faster than shown, this is an indication that the corresponding spool
stop requires adjustment. For information on adjusting spool stop (s), see HPI Valve
Adjustment for Swing & Lift Speeds.).1.Recheck the threshold movement. If a large change in high range voltage, 1/2 volt or
more was necessary, will normally effect the threshold voltage adjustment.
2.Turn the ramp time trim pot CW 3 – 4 turns.3.Move the controller handle quickly to 3/4 full travel and note function response. Continue
to adjust ramp time until a gradual response is obtained without excessive time delay.

SERVICE NOTES:
1. On both A and B Low Range trim pots, turn adjustment screws 10 full turns
clockwise. (On models TB 37,42,42J, 47J, 420 and 50, Low Range is not used for
Lift/Swing low speed. After preset of 10 turns on both trim pots, precede to the Hi
Range adjustment.) On these machines low is, however, used for elevated drive speeds.
2. Preset both the A and B Threshold trim pots. The controller handle must be moved at least 1½ inches off center or until machine is just barely starts to creep and adjust
per above chart.
3. Move controller handle to full on and adjust the A and B Hi Range trim pots per
above chart.
4. Elevate the boom above horizontal or extend out past 4’ for Drive/Lift/Swing. Move
controller handle full on and adjust Low range trim pot. (Low Range Trim Pot only
applies to models TB 80, 85J, TB 80, 85J FA, Lift/Swing/Drive and TB100, 120 and
126 Swing/Drive only. Remove wire #122 from “R” terminal of controller and adjust
the Low Range trim pot.)
20
Checking Lift/Swing Speeds From The Ground Controls
Always verify your ground control speeds first, before attempting a controller adjustment.
Lift/Swing speeds should be checked from the ground control, not form the platform. At the
proportional control valve for lift/swing, each section has spool stops that limits the travel of
the main spool.
Example: Swing is faster one direction than the other. This could indicate that the spool stops
are out of adjustment or if you’ve recently installed a new PWM Module and haven’t set it yet.
See PWM Module Adjustment procedure on page 25.

Swing & Lift Control Valve Adjustment:
Before adjusting the Lift or Swing controller for speeds at the platform, actual Lift or Swing
speeds should be verified from the ground control as speeds for Swing and Lift are set by
spool stops located on the Enerpac / Apitech / Parker proportional control valves. The
preset voltages should provide enough voltage to achieve full spool travel for maximum
speeds. Setting the voltages excessively high, can produce “High End” dead band, (When controller handle position changes without a corresponding change in the functions speed).

Control Valve:
Apitech Proportional Control Valve Location
This is the manual
spool stop. The top screw adjusts the C2 (CCW) function and the bottom screw adjusts the C1 (CW) function. Do not over tighten jam nut as damage could occur to spool manual stop.
Turn spool stop clockwise until swing
stops. Turn spool stop counter clockwise to
obtain proper swing speed, 90 to 100 seconds in a full 360° with the boom fully
retracted. Check both directions to insure
your times are close to the same in both
directions. If you cannot get the speed the
same in both directions you may have to
do a centering adjustment. See procedure page 9.

Swing Speed Adjustment on ApitechProportional Control Valve (continued):
This is the centering null
adjustment screw for swing ONLY. If the swing speed is
faster one direction than the
other you can adjust the
centering of the spool.
Warning: The centering null adjustment can be adjusted to
far where the machine will
swing as soon as you step on
the foot switch or hold up on
the ground control switch.

Pulse Width Modulation Module is located behind the Ground Control panel.
The PWM module sends a pulsing signal through the Speed Rheostat located
on the ground control panel. The speed rheostat regulates the PWM signal from fast to slow to the pulsars on the Apitech proportional control valve for the Lift
and Swing functions. If a new PWM module is installed, it will require setting so
the lift speeds will be correct from the ground control station.
PWM Module Adjustment:1.Turn Speed trim pot on PWM module full on clockwise. (Trim pot only has ½
to ¾ turns of adjustment. Do not over adjust trim pot as damage can occur.)
2.Rotate the speed rheostat knob on ground control panel to the fast position
and then rotate the rheostat knob form to the 10:00 position from fast.

PWM Module Adjustment (continued):
3. Using the Boom Up control switch at the ground control, adjust the threshold trim pot
on PWM module until the boom just starts to move. Rotate the speed rheostat from fast
to slow checking for metering control with out excessive dead band.
4. Rotate the Speed rheostat to the Fast position. Place the boom in the fully stowed
position. Time the boom through it full range of movement. From fully stowed to fully
elevated should be 65 to 75 seconds and fully elevated to fully stowed should be 60 to
70 seconds. If lift speeds are to fast, turn the Speed trim pot counter clockwise to
decrease boom speed.
Service Tips:
Lift and Swing will not work from ground control station but will from platform.Check rheostat position
Check signal from PWM Module (#172) to Lift/Swing switches
When moving the rheostat at the ground control from fast to slow and lift or swing
stops, replace the rheostat.
The Jib function is a non-proportional function. The approximate “Lift and Lower”
times are 25 – 35 seconds.

To read the pressure limiters settings, install a 0-5000 psi gauge at the pump compensator test
port.
For Lower and Lift, dead head the lower and raise functions to read the pressure limiters
setting.
For Reverse and Forward drive, remove the outboard hose as indicated above, plug the hose
and cap the port. Deadhead the drive both forward and reverse to read the limiters settings.
Reconnect the hose when finished.
Note: For two wheel drive units adjust relief’s to 2500 PSI, on four wheel drive units set relief’s
to 2800 PSI.
The Inlet Relief is Factory set at 3600 psi (No Adjustment Required). It provides protection for
the Hawe Proportional Control Valve from damage in the event of extremely high pressures
produced when a pump compensator fails.

Spool Stop Adjustment and Manual Over Rides
The Spool Flow Stop Adjustments shown above, are located inside of each Manual Over Ride lever
of the Hawe Proportional Control Valve. Before making any adjustments of the spool flow stop,
verify the speeds by operating the lift and swing functions from the ground controls. When verifying
the drive speeds, mark off 50 feet, and at a rolling start time drive within the 50 feet.
For 3 MPH = 50’ in 11 to 14 seconds, Boom Down and Fully Retracted, Range in Hi, and Hi Engine
Rpm's.
For 1 MPH = 50’ in 33 to 38 seconds, Boom Elevated above Horizontal and/or Extended out
approximately 6’, Range switch in Low, and Low or Mid Engine Rpm's. (Note: Some early
production units were built using the F3L2011F Deutz Diesel, using a throttle solenoid for high and
low engine rpm,s. Later production uses the Addco Actuator system On both the Deutz F3L2011F
and the Cummins 3.3 diesel engines. See engine RPM adjustment.)

Spool Stop Adjustment and Manual Over Rides
NOTE: Adjustment of the Lift / Swing Spool Stops should only be done if one direction is moving faster
than the other.
Timing the unit from the ground control station will determine if an adjustment will be required.
If an adjustment is required for the Lift or Swing Spool Stops, you will need two metric hex-keys, one
2mm and one 2.5mm. (see above pictures for locations)
1. Loosen the Spool Stop Set screw located on the L. H. side of each manual override for the section to be
adjusted using a 2mm hex-key. (see above pictures for locations) When adjustment is complete, use a
small amount of Loctite to secure the set screw.
2. This step will require a second person. Start engine form the ground control station and activate the
system enable switch. Using a 35mm bolt approximately 2-3” long or a punch of approximately the same
diameter and length, insert bolt into Manual Override Actuating Bolt Hole. (see above picture) Facing
the control valve, and moving the manual override lever to the left or the right will make the valve
respond as follows:
Moving the Manual Override to the Left: Swing CCW, Boom UP, and Drive FWD
Moving the Manual Override to the Right: Swing CW, Boom Down, and Drive Reverse
3. Move the manual override in the slower direction. Using a 2.5mm hex-key, turning the hex screw in or
CW will decrease spool movement for slower speed, turning the hex screw out or CCW will increase
spool movement for faster speed. Only move the hex screw 1/8 to 1/4 “ at a time. Re-check the time of
the slower function to see if the speed has increased to equal the faster direction. If not repeat step 3. If
speeds are now approximately the same, re-tighten the spool stop set screw.

Hawe Service Tips
•Stand-by pressure is very critical to the smooth operation of this valve. If we
are seeing an oscillation in the boom functions it is a good idea to make sure
the stand-by pressure on the machine is between 350 to 400 psi. (jerky boom movement or the same effects of a bad accumulator.)
•In very cold weather if the functions are slow or sluggish one option is to put a
second tank line from the “T” port on top of the valve, directly to the hydraulic
tank. If this problem goes on for an extended period of time without being fixed it is possible that you may blow the handle section seals. Hawe
recommends that if this happens that you replace the whole handle section
instead of trying to replace the seals.
•Under normal operation, if we have slow or sluggish operation and by moving the manual override the operation is responsive and of normal speed. The
“GAP” filter may be plugged. Remove the gap filter from the “M” port clean and
re-install.
•Shuttle valve location under the port plate, once the port plate is removed you
will see a small brass fitting with a screwdriver slot in it. Remove this fitting
taking caution not to damage the o-rings on this fitting. Once this fitting is out
the shuttle ball will be in the cavity. The size of the shuttle ball is approximately
3mm (1/8”).
•If the valve is disassembled the thru bolts will need to have a torque value of,
17 ft/lbs (23Nm) for the larger bolts and 7ft/lbs (9.5Nm) for the small bolt.
•The cross port relief’s have no external adjustments. They are factory set using shims for spring pressure.
•The relief valves are not a cartridge type, if you remove the adjustment screw
you will have access to the spring and seat. If you believe you have a relief
valve problem, back the relief valve off, run that function, then reset the pressure. The relief valves will leak oil if the cap is not put back on after setting
the pressure.
