Section 3 - Operating ProceduresPre-Towing Checklist

Before transporting/towing the machine, make sure maintenance on your vehicle is current as towing puts additional stress on the tow vehicle.Use the following checklist to aid in making sure all safety and maintenance checks are in place:

• Check tire pressure on both the tow vehicle and trailer. Service tires, as required

• Make sure the wheel lug nuts/bolts on the tow vehicle and trailer are tightened to the correct torque

• Make sure the tow vehicle is rated (has the capacity) to tow the ma-chine

• Make sure the hitch ball is the correct size and is rated for the weight of the machine being towed

• Be sure the hitch, coupler, draw bar, and other equipment that connect the trailer and the tow vehicle are properly secured and adjusted

• Check that the wiring is properly connected - not touching the road, but loose enough to make turns without disconnecting or damaging the wires

• Make sure all running lights, brake lights, turn signals, and hazard lights are working properly

• Verify that the brakes on the tow vehicle are operating correctly

• Check that all items are securely fastened on the trailer

• Be sure the trailer jack, tongue support, and any attached stabilizers are raised and locked in place

• Check load distribution to make sure the tow vehicle and trailer are properly balanced front to back and side to side

• Check side and rear-view mirrors to make sure you have good visibility

• Check routes and restrictions on bridges and tunnels.

• Make sure you have wheel chocks and jack stands.

29

Section 3 - Operating ProceduresSafety Tips for Driving While Towing

Take time to practice before driving on main roads and never allow anyone to ride in or on the trailer. Before you leave, remember to check routes and restrictions on bridges and tunnels. Consider the following safety tips each time you drive with a trailer.General Handling

• Use the driving gear that the manufacturer recommends for towing

• Drive at moderate speeds. This will place less strain on your tow vehi-cle and trailer. Trailer instability (sway) is more likely to occur as speed increases

• Avoid sudden stops and starts that can cause skidding, sliding, or jackknifing

• Avoid sudden steering maneuvers that might create sway or undue side force on the trailer

• Slow down when traveling over bumpy roads, railroad crossings, and ditches

• Make wider turns at curves and corners. Because your trailers wheels are closer to the inside of a turn than the wheels of your tow vehicle, they are more likely to hit or ride up over curbs

• To control swaying caused by air pressure changes and wind buffeting when larger vehicles pass from either direction, release the accelerator pedal to slow down and keep a firm grip on the steering wheel

Braking• Allow considerably more distance for stopping

• Always anticipate the need to slow down. To reduce speed, shift to a lower gear and press the brakes lightly

Acceleration and Passing• When passing a slower vehicle or changing lanes, signal well in advance and make sure you allow extra distance to clear the vehicle before you pull back into the lane

• Pass on level terrain with plenty of clearance. Avoid passing on steep upgrades or downgrades

30

Section 3 - Operating Procedures• If necessary, down shift for improved acceleration or speed mainte-nance

• When passing on narrow roads, be careful not to go onto a soft shoul-der. This could cause your trailer to jackknife or go out of control

Downgrades and Upgrades• Down shift to assist with braking on downgrades and to add power for climbing hills

• On long downgrades, apply brakes at intervals to keep speed in check. Never leave brakes on for extended periods of time or they may over-heat

• Some tow vehicles have specifically calibrated transmission tow-modes. Be sure to use the tow-mode recommended by the manufac-turer

Backing Up• Put your hand at the bottom of the steering wheel. To turn left, move your hand left. To turn right, move your hand right. Back up slowly. Because mirrors cannot provide all of the visibility you may need when backing up, have someone outside at the rear of the trailer to guide you, whenever possible

• Use slight movements of the steering wheel to adjust direction. Exag-gerated movements will cause greater movement of the trailer. If you have difficulty, pull forward and realign the tow vehicle and trailer and start again

Parking• Try to avoid parking on grades. If possible, have someone outside to guide you as you park. Once stopped, but before shifting into Park, have someone place blocks on the downhill side of the trailer wheels. Apply the parking brake, shift into Park, and then remove your foot from the brake pedal. Following this parking sequence is important to make sure your vehicle does not become locked in Park because of extra load on the transmission. For manual transmissions, apply the parking brake and then turn the vehicle off in either first or reverse gear

• When uncoupling a trailer, place blocks at the front and rear of the trail-er tires to ensure that the trailer does not roll away when the coupling is released.

31

Section 3 - Operating Procedures• An unbalanced load may cause the tongue to suddenly rotate upward; therefore, before un-coupling, place jack stands under the rear of the trailer to prevent injury

The Chipping Cycle (Overview)Machine Setup/Op Area Setup

Before any chipping can begin, there are three important areas to inspect, set-up, and prepare each time you use the chipper. The work site, the brush and the chipper.Work Site Preparation

• Clear objects containing metal, stones, etc. that may damage the machine

• Clear any objects that may trip or entangle the operator

• Check that the area is clear of utility and power lines

• Be sure the area is well lit with good ventilation (when indoors)

• Set-up a sufficient space to work in

• Designate an area for the brush pile and chipped wood

• Create a clear walking path for loading the brush

• Ensure emergency equipment is available on the work site

• Always have two trained personnel dressed in safety gear on the work site at all times

Proper preparation and organization of the brush and branches will provide an efficient chipping process, as well as creating safe working conditions and reducing the possibility of unexpected maintenance expenses.

32

Section 3 - Operating ProceduresBrush Preparation

DANGERForeign material (metal, stones, glass) in the chipper will cause damage and potentially shatter the chipper knives resulting in proper-ty damage, serious injury or death.

Vines left on the wood may cause entangle-ment of operating personnel, or hide foreign material resulting in equipment damage, seri-ous injury or death. Always remove vines from the material to be chipped. Do not leave vines in the work area or place vines in the chipper.

CAUTIONLifting heavy objects may cause serious back injury. Always use proper lifting technique when loading the machine.

To prepare the wood and brush:• Cut the lead end of the brush at an angle. This will help ease the feed wheel open and facilitate feeding

• Cut the brush into lengths long enough to be safely fed into the chipper without the operators hands entering the infeed chute. The average length should be no shorter than 4 feet long

NOTE: Place short pieces on top of longer pieces.• Cut the wood into a weight that can be easily lifted without injury to the operator

• The chipper is designed to process clean wood. Brush and wood should be clear of debris and dirt or any items that may damage the machine

33

Section 3 - Operating ProceduresFeeding Brush Into the Chipper

The engine throttle must be advanced to the full (max) position for the safety control bar functions to be enabled. When you are about to feed brush into the chipper, move the safety control bar to the feed position, see Figure 24, Engine Startup procedure.Note: At least two trained operators must be on the work site at all times. The work site is an area where the operators can see, hear, and react to an emergency in a few seconds.To feed the brush:

1. Pick up a limb from the brush pile that is light enough to easily maneuver. Keep your back straight and lift with your legs. The cut-end should be facing towards the infeed.

NOTE: When breaking in a machine, it is recommended that you begin by feeding 2”-3” diameter pieces into the chipper, gradually working up to the larger diameter pieces during the first 4-8 hours of work.

2. Insert the brush onto the infeed tray making sure your hands do not enter the infeed chute area. When you feel the material pull away, release the material and let it pull through the feed wheel.

Note: To safely feed shorter pieces, place the safety control bar into the neutral position as the longer material enters the feed wheel. Lay the shorter material on top of the longer material (before entering the infeed!) then place the safety control bar back into the forward position and begin the chipping process again.

3. Quickly turn, and face away from the infeed. Keep moving along your motion path.

4. Check the discharge chute and make sure the wood chips are projecting at the correct angle. If necessary adjust the discharge chute.

Note: It is the operators responsibility to keep all bystanders away from the work site.

34

Section 3 - Operating Procedures

Section 3 - Operating Procedures

Machine Setup/Preparation

DANGERBefore operating, always block the wheel with wheel chocks (as shown below) and ensure the chipper is on stable level ground when not at-tached to a vehicle. Failure to do so will result in unexpected movement, serious injury or death.8

Wheel chocks

DANGERThe chipper MUST stay connected to the tow vehicle when operating. Operating the chip-per while disconnected from the tow vehicle is unstable and may cause injury or death to personnel.

Before starting operation the chipper must first be placed on a stable sur-face and secured so that it does not move. The chipper can only be operat-ed by while hitched to a tow vehicleWhen operating the chipper:

FIGURE 23

36

Section 3 - Operating Procedures• The vehicle used to tow the machine must be capable of towing the machine

• Park the vehicle and the chipper on a level surface

• The vehicle must be completely stopped, with the parking brake set

• There must NOT be a driver in the vehicle

• The hitch must be properly secured to the vehicle with locking pins installed

• Connect safety chains and cables to the vehicle. Two lengths of chain must be used. The lengths of chains should be equal in length and shall be crossed under the tongue of the chipper and properly attached to the towing vehicle

• Hook up electrical connections and check that tail lights and turn sig-nals are in working order

• The chipper must be level, with the machine parallel to the ground

Adjusting the Discharge ChuteOnce you have the machine secured and level, the next step in machine preparation is setting up the discharge chute. See Features and Function section for more detail.

• Be sure the infeed chute is clear of any debris

• Rotate the discharge chute in the direction you want the wood chips projected. The discharge chute can rotate 270º. Adjust the height of the discharge chute if necessary

• Adjust the deflector for the desired angle of projection. Direct chips away from the work area and bystanders

Battery Maintenance

WARNINGThe battery generates explosive gas during normal operation. Keep ignition sources away at all times. Battery acid can cause se-vere burns. Wear protective gear when han-dling the battery.

Follow these guidelines when handling and maintaining the battery:• When connecting or disconnecting the cables, always handle the neg-ative (-) terminal first.

A

B

50

Section 4 - Service & Maintenance Procedures• After completing the connection, reconnect and tighten the cables to the terminals.

• Apply grease to the terminals to prevent corrosion

• Check the battery terminals for corrosion (white or yellowish powder)

• Remove corrosion by covering the terminals with a solution of baking soda and water. After the mixture bubbles and turns brown, wash it off with water. If there is severe corrosion, clean with a wire brush, and dry with a paper towel.

Tire Maintenance

DANGEROver inflated tires will cause a tire to explode and result in serious injury or death. Always maintain a safe distance away from the tire during inflation. Use a hose with a pressure gauge. Never over inflate a tire!Improper support of the chipper during a tire change will result in the machine tipping over and causing serious injury or death. Always set up on a flat, solid surface and ensure the machine is properly supported.

• Maintaining proper air pressure in the machine’s tires is critical to safe operation. Correct air pressure provides balance and stability during transportation and operation. Never exceed maximum inflation pres-sures when sealing tire beads on rims.

• To add air to the tires remove the stem cap and place the air pump nozzle securely on the stem. Avoid twisting or bending the stem while adding air. Inflate the tire to the recommended pressure listed on the tire. After inflating the tire, replace the stem cap. Doing so will prevent loss of air pressure.

• Repairing or replacing a tire should only be done by an individual that has the proper equipment and training. In the absence of either always

51

Section 4 - Service & Maintenance Procedureshave a qualified tire repair service conduct the maintenance. Detailed tire mounting instructions, including safety precautions, are available from the Rubber Manufacturers Association or the tire manufacturer.

• The chipper comes with high-grade tires. Replace with a similar grade.

Tire Replacement1. See Figure 35. Install wheel chocks (A) on side opposite of the tire to

Section 4 - Service & Maintenance ProceduresHydraulic

WARNINGHydraulic oil will vaporize and potentially ig-nite resulting in explosion, fire and possible serious injury. Keep hydraulic oil away from ignition sources (e.g.: flame, smoking etc.).

Hydraulic oil leaks will result in puddles and slippery conditions which may result in seri-ous injury. Always clean up spills and fix leaks immediately.

Pressure may be stored in the hydraulic sys-tem even after the power unit is turned OFF. Relieve hydraulic pressure and lockout the machine before conducting maintenance.

Hydraulic oil is under pressure. Spraying flu-id from a leak can burn or penetrate the skin and cause serious injury. If fluid penetrates the skin, immediately seek medical attention to have it surgically removed!

The hydraulic components (pump, motor) and oil are hot during operation and can cause se-vere burns. Always wear protective face gear and clothing during operation and mainte-nance.

GeneralWhen conducting maintenance on the hydraulic system; be cautious of leaks, hot components (pumps, motors, relief valves) and stored energy. Al-ways follow safety warnings and procedures when conducting maintenance on the hydraulic system.

53

Section 4 - Service & Maintenance ProceduresBefore Conducting Maintenance:

• Allow the machine to cool down

• Relieve pressure within the hydraulic system. Examples of where energy may be stored include: stalled feed wheel, suspended loads, charged accumulators and electric voltage.

• Check for leaks. Use a piece of cardboard to check for leaks. Never use your hand!

The hydraulic system provides the fluid powering certain parts of the ma-chine’s operation. The main components requiring maintenance include the hydraulic oil, filter and pump.

Testing the Hydraulic OilThe hydraulic oil should be tested every 250 hours or if there are signs of oil degradation. Signs of degradation include:

• A change in oil color

• Bad aroma to the oil

• Dirty or gritty feel to the oil

• Regular hydraulic component failure

• Louder than normal operation sound

The oil quality may be checked using a commercially available test kit or a simple Blotter Spot test. The Blotter Spot test consists of placing a drop of oil on a piece of blotter paper. If the blotter remains colorless or develops only a light yellow ring, oxidation is under control. Even when color develops but is uniform throughout, the oil is serviceable. If the sample shows distinct rings, the fluid should be changed. When a dark spot remains in the middle but lighter-colored oil migrates outward in the blotter paper, the oil has or is about to dump sludge or other products into the system. This indicates that the time for fluid replacement has passed.

54

Section 4 - Service & Maintenance ProceduresChanging the Hydraulic Oil & Filter

Under normal conditions hydraulic oil should be changed every 400 oper-ating hours or yearly, which ever comes first. In more severe conditions it should be changed every 200 hours or six months. Always use hydraulic oil that contains anti-wear additives. Always keep the level of oil in the tank full. Failure to do so can result in air getting into the pump, a reduction of oil pressure, and slow operation.

WARNINGTo avoid burn injuries, make sure machine has been turned off long enough for hydraulic fluid to and associated parts to cool down.Place machine on level surface and make sure wheel chocks are in place to stabilize machine, as required.

1. See Figure 37. Remove hydraulic oil fill cap (A).

58

Section 4 - Service & Maintenance ProceduresRefueling

WARNINGExplosive Fuel can cause fires and severe burns. Do not fill fuel tank while engine is hot or running.Gasoline is extremely flammable and its va-pors can explode if ignited. Store gasoline only in approved containers, in well ventilat-ed, unoccupied buildings, away from sparks or flames. Spilled fuel could ignite if it comes in contact with hot parts or sparks from igni-tion. Never use gasoline as a cleaning agent.

Fuel Specifications

NOTICENOTE: E15, E20 and E85 are NOT approved and should NOT be used; effects of old, stale or contaminated fuel are not warrantable.Refer to the engine OEM manual for specific information regarding the type of fuel to use.Fuel must meet these requirements:

• Clean, fresh, unleaded gasoline.• Octane rating of 87 (R+M)/2 or higher.• Research Octane Number (RON) 90 octane minimum.• Gasoline up to 10% ethyl alcohol, 90%unleaded is acceptable.• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blend (max 15% MTBE by volume) are approved.

• Do not add oil to gasoline.• Do not overfill fuel tank.• Do not use gasoline older than 30 days.

59

Section 4 - Service & Maintenance ProceduresFilling & Storage of Fuel

Fuel should be stored in approved containers and kept in a clean, protect-ed environment. Avoid storing fuel over a long period of time. The fuel tank should be filled 3/4 full at the end of each days operation. This will help prevent condensation as the air cools and allow for vapor expansion when the temperature rises. The fuel could overflow if the tank is filled completely and there is an increase in temperature.

Discharge Chute Cleaning

DANGERNever attempt to remove material by starting the machine and engaging the chipper to blow material out. This is a very dangerous and un-safe practice.Two (2) people shall be involved when attempt-ing to open the discharge chute. The chute must be securely supported while removing support bolts. Never stand directly under the chute as it can fall, causing injury.

CAUTIONMachine components may be hot or have sharp edges which could cause serious inju-ry. Always wear protective gear during opera-tion and maintenance.

Plugging is mainly caused by the engine RPM’s dropping too low. This drop can be caused by running the unit at less than full RPM’s, by dull knives that do not chip the wood efficiently or by trying to overfeed material that is either too large or too soft, which prevents chipping. If the unit has auto feed it should be set high enough to prevent a low RPM situation.

1. Perform the Engine Lockout procedure to prevent inadvertent operation of the machine.

2. Make sure the chipper disc has stopped turning.

3. Pull material out from the open end of the discharge.

60

Section 4 - Service & Maintenance Procedures4. If required, perform the Chipper Hood & Disc Lockout procedure to

access the lower section of the discharge chute to remove material.

5. Reinstall components and attempt chipping again using small material to determine if chipper discharges properly.

Chipper Disc Knives

DANGERA rotating chipper disc can pinch body parts, entangle loose clothing, jewelry, and long hair which may result in cuts, mutilation, serious injury or death. Before initiating maintenance throttle the engine down and shut the engine OFF. Wait for the chipper disc to completely stop rotating and insert the disc lock pin.The chipper disc will coast for several minutes after the machine is shut off. Do not open the chipper hood until the disc rotation has com-pletely stopped. Serious injury, mutilation or death can occur.Debris may be projected during the mainte-nance of the chipper knives and result in eye injury, skin punctures, and cuts. Always wear protective equipment and gear such as gog-gles and work gloves.

NOTICEExcessive heat, indicated by discoloration of the knife edge, will lead to microscopic cracks that can cause the knife to break when it is put back into service. Do not use knives that have been exposed to excessive heat from sharpening.

61

Section 4 - Service & Maintenance ProceduresGeneral Guidelines

To ensure maximum efficiency of the chipping operation the chipper knives must be properly maintained. The time between sharpening or replacement will depend on the type of wood and operating conditions. Indication of dull knives include poor quality, excessive oversize chips and poor feed char-acteristics. Always maintain proper knife sharpness. It is important to follow these guidelines to ensure efficient chipping:

• Use original Morbark Inc. knives with the correct steel composition and hardness. Immediately replace worn knives.

• Keep the knife edge sharp and anvil square. Use matched sets.

• Maintain the proper clearance between the chipper knife and anvil.

• Use the correct hardware to mount the knife to the holder and maintain the correct torque to the bolt. Keep the knife pocket and holder clean and free of debris.

Accessing the Chipper Knives1. Perform the Engine Lockout procedure to prevent inadvertent

operation of the machine.

2. Perform the Chipper Hood & Disc Lockout procedure to safely access the knives.

3. See Figure 41, next page. Remove Slot Cover (A) by removing bolts and washers (B). Set parts aside.

64


Sharpening the Chipper KnivesGeneral Notes:

• When sharpening the knife edge use proper grinding techniques (hand file, power belt sander with fine paper or conventional knife grinder with coolant system) to reduce the possibility of excessive heat build up and provide a good cutting edge.

• Do not use straight wheel grinding. This method will result in a hollow or concave effect and shorten the life of the knife.

• Use a non-petroleum base coolant such as De Santo (orange label) grinding coolant when using a grinding machine. Mix approximately one part coolant to 50 parts of water. The coolant should be applied on the wheel about 1” above the knife with full pressure. This will keep the wheel clear and free to cut without burning or damaging knives. Do not overfeed the grinding machine.

Anvil Maintenance

DANGERFailure to lockout the machine (e.g. raise yoke, shut power off) will result in unexpected operation and cause serious injury or death. Always lockout the machine before conduct-ing maintenance (see Safety: Lockout Proce-dure).A rotating chipper disc can pinch body parts, entangle loose clothing, jewelry and long hair which will result in cuts, mutilation, serious injury or death. Shut down the engine, wait until the chipper disc completely stops rotat-ing and insert the disc lock pin before initiat-ing maintenance.

NOTICEIncorrect clearance between a chipper knife and anvil will result in poor chipping performance, damage to the chipper knives and undue stress on the chipper. Always maintain the proper knife-anvil clearance.

General NotesThe anvil is located behind the infeed next to the chipper disc. The anvil and chipper disc work together in chipping the brush, therefore it is important the clearance between the anvil and knife are accurate.To ensure maximum efficiency of the chipping operation the anvil must be properly maintained. It is important to follow these guidelines to ensure efficient chipping:

• Keep the anvil square

• Maintain the proper clearance between the chipper knife and anvil

• Inspect, flip or replace anvil when required

67


Accessing the Anvil1. Perform the Engine Lockout procedure to prevent inadvertent

operation of the machine.

2. Perform the Chipper Hood & Disc Lockout procedure.

Section 4 - Service & Maintenance ProceduresMachine StorageUse the following guidelines when preparing the machine for long-term storage:

• Make sure all areas of the machine (engine and exhaust area, infeed, discharge, etc.) are clean and free from debris

• Fill fuel tank to at least 3/4 full to avoid condensation buildup in tank and add fuel extender if machine will be stored and not used for more than 6 months

• Clean up all fuel and/or hydraulic spills

• Perform the Engine Lockout procedure

• Store in an enclosed facility if possible to avoid exposure to weather, as well as reduce possibility of theft and/or vandalism

• Ensure tires are clean and properly inflated

• Make sure infeed tray is closed

Torque TablesMaking sure that all the bolts are regularly checked and tightened to the proper torque is critical. Tables 4 to 7 show the proper torque relative to the bolt size and type. When using these tables, keep the following guidelines in mind:

• The values in the chart are based on use of clean, dry threads.• Use the next higher torque value when specific torque values are not available.

• When replacing a cap screw with a higher grade, use the torque speci-fications of the new screw.

• Do not use the torque values shown in this chart in place of those specified in other sections of the manual.

• When oil is used as a lubricant, reduce the torque by 10%.• When using new plated cap screws, reduce the torque by 20%.• Use the Grade 5 torque chart when using cap screws that are threaded into aluminum. These may require reductions in torque of 30% or more and must attain two cap screw diameters of thread engagement.

• When using rivet nuts, do not exceed 25 ft-lb of torque.

Section 4 - Service & Maintenance ProceduresTroubleshooting

HydraulicThe hydraulic pump is critical to the operation of the chipper. Operators should always be alert for possible problems with the pump during opera-tion. Symptoms indicating problems with the pump include:

• A noisy pump

• Overheating

• High discharge pressure

• Pump not pumping

• Low system pressure

• Sluggish start-up

Troubleshooting the hydraulic system (see Table 8) involves talking with the operators, understanding the schematics and inspection of the machine. After identifying the problem determine the root causes. It is possible there is more than one cause of the malfunction.Start by creating a list of possible causes. Put the easiest ones to eliminate and do not require dis-assembly or down time first. Systematically test, elim-inate or repair possible causes.Initiate corrective action to avoid future maintenance problems and opera-tion downtime.Table 8 - Hydraulic Troubleshooting

Symptom Possible Cause Corrective ActionNoisy Pump Air in system Tighten loose fittings. Replace cracked

hoses and damaged parts.Cavitating pump Open clogged or restricted intake line

or plugged air vent in tank.Loose/worn parts Replace worn gaskets. Ensure the oil

is the proper type and clean.Stuck parts Dis-assemble pump and clean with

solvent and dry thoroughly before reas-sembling. Do not use hard tools, files or emery cloth on machined surfaces. Replace rusted parts.

Pump/bearing Disassemble and inspect pump & flange bearing. Repair/replace defec-tive components, as required.

damaged parts.Oil too thick Drain tank and replace with oil of the

proper viscosity.Low system pressure

Relief value set-ting to low

Block pressure line beyond relief valve and check line pressure with a pres-sure gauge, adjust relief valve setting so fluid flows to point of use.

Relief valve stuck open

Clean dirty relief valve. Check oil for dirt and deterioration. Change if neces-sary.

Broken, worn or stuck parts

Block pressure line beyond relief valve and check line pressure with a pres-sure gauge. No pressure buildup and functional relief valve indicate mechani-cal problems. Inspect pump for worn or broken parts. Replace if necessary.

Valves sticking or binding

Check oil for deterioration (e.g.: dirt, sludge, varnishes and lacquers). Change if necessary.Inspect pump parts for misalignment, wear or damage. Replace if necessary.

Sluggish start-up

Oil too thick at starting tempera-ture

Run the machine for short period and see if the oil thins out. If not, change the oil to a lighter viscosity. See fluid manufacturers recommendations.
