AVOID ACCIDENTS Most accidents, whether they occur in industry, on the farm, at home or on the highway, are caused by the failure of some individuals to follow simple and fundamental safety rules or precautions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognising the real cause and doing something about it before the accident occurs.

Regardless of the care used in the design and construction of any type of equipment there are conditions that cannot be completely safeguarded against without interfering with reasonable accessibility and efficient operation.

Carefully read indications, cautions and safety warning quoted in the “SAFETY RULES” section.

A careful operator is the best insurance against an accident.

The complete observance of one simple rule would prevent many thousand serious injuries each year.

That rule is: Never attempt to clean, oil or adjust a machine while it is in motion.

PRECAUTIONARY STATEMENTS PERSONAL SAFETY Throughout this manual and on machine decals, you will find precautionary statements (“CAUTION”, “WARNING”, and “DANGER”) followed by specific instructions. These precautions are intended for the personal safety of you and those working with you. Please take the time to read them.

CAUTION: The word “CAUTION” is used where a safe behavioral practice according to operating and maintenance instructions and common safety practices will protect the operator and others from accident involvement.

WARNING: The word “WARNING” denotes a potential or hidden hazard which has a potential for serious injury. It is used to warn operators and others to exercise every appropriate means to avoid a surprise involvement with machinery.

DANGER: The word “DANGER” denotes a forbidden practice in connection with a serious hazard.

Failure to follow the “CAUTION”, “WARNING”, and “DANGER” instructions may result in serious bodily injury or death.

MACHINE SAFETY Additional precautionary statements (“ATTENTION” and “IMPORTANT”) are followed by specific instructions.

These statements are intended for machine safety.

ATTENTION: The word “ATTENTION” is used to warn the operator of potential machine damage if a certain procedure is not followed.

IMPORTANT: The word “IMPORTANT” is used to inform the reader of something he needs to know to prevent minor machine damage if a certain procedure is not followed.

II

SAFETY PRECAUTIONS Equipment should be operated only by those who are responsible and instructed to do so. Unsafe operating practices and improper use of the skid-steer loader and its attachments on the part of the operator can result in injuries.

Observe the following safety precautions at all times:

1.

Give complete and undivided attention to the job at hand so that complete control of the loader is maintained at all times.

2.

Be aware of ground conditions, drive slowly over rough ground and on slopes, keep alert for holes, ditches and other irregularities that may cause the loader to overturn.

3.

Avoid steep hillside operation which could cause the loader to overturn.

4.

Never transport a loaded bucket at full height.

Operate the loader with the load as low as possible until it becomes necessary to raise the boom to discharge the load into a truck, container, etc.

III

5.

Reduce speed when turning so there is no danger of the loader overturning.

6.

Never drive up or back up a hill or incline with a raised boom or the loader could overturn.

7.

Always look behind you before backing the loader.

8.

Maintain proper transmission oil level to prevent loss of hydrostatic braking. Check fluid levels on a regular basis as directed in this manual.

9.

Do not allow passengers to ride on the loader at any time.

IV

10. Do not allow children to operate the loader or ride on the loader at any time.

11. Do not allow anyone to operate the loader without proper instruction. Legislation in many countries require that all operators be instructed on the proper procedures and operation of the machine before use.

12. Do not operate the loader in any position other than while in the operator’s seat with the seat belt securely fastened.

13. Before starting the engine, be sure that all operating controls are in neutral and parking brake is engaged.

14. Never operate the loader engine in a closed building without adequate ventilation.

V

15. Refuel the loader outdoors with the engine shut off. Replace the fuel cap securely. Use an approved fuel container. Do not smoke when handling fuel. Avoid spilling fuel.

16. After operating the engine, never touch the muffler, exhaust pipe, engine or radiator until they have had time to cool.

17. Dress appropriately - wear relatively tight-fitting clothing when operating the loader. Loose or torn clothing can catch in moving parts or controls.

18. Before servicing the loader or any of its attached equipment, be sure that the attachments are lowered to the ground or that the boom arms are supported by the boom lock pins.

VI

19. Do not work under overhangs, electric wires, or where there is danger of a slide.

20. Wear an approved safety hat when operating the machine and while in any work area. Wear a suitable hearing protective device such as earmuffs or earplugs if you are exposed to noise exceeding 85dBa. In the interests of safety and personnel comfort, protective clothing, boots and gloves should be worn where appropriate.

21. When driving the loader on a road or highway, use warning lights or warning devices as may be required by local or state government regulations.

Warning lights and signs are available through your dealer.

22. Keep the loader clean. Do not allow trash, debris or other articles to accumulate in the cab, floor or foot control pedal area that may hinder safe machine operation.

VII

23. Under no circumstances should the frame, screens, or protective structures be modified.

Never operate the loader with any of the shielding removed. Never operate the loader without windows and/or screens in place. Never extend any part of the body outside of the operator’s area.

24. Always properly tie down the skid-steer loader to a truck or trailer before transport.

25. Make sure all bystanders are at a safe distance away from the loader before starting the engine.

26. Do not allow anyone near the loader while the engine is running and the loader is operational.

VIII

27. When using the skid-steer loader to crane objects, do not allow any person to ride on objects being craned.

28. Do not use the skid-steer loader as a work platform for supporting materials.

29. Do not lift personnel or allow personnel to work while standing in the bucket or on other attachments. This is not a man-lift.

IMPORTANT: Legislation in many countries state it is the employer’s responsibility to fully instruct each operator in the proper and safe operation of all operative equipment. Both employer and employee should therefore thoroughly familiarise themselves with the contents of this manual.

IMPORTANT: Legislation in many countries state it is an employees' responsibility to fully understand the vehicle operation and ensure safe handling and prevent harm to themselves or others. Therefore thoroughly familiarise yourself with the contents of this manual.

IMPORTANT: ``Do not put the machine into service until the machinery into which it is to be incorporated has been declared in conformity with the provisions of the directive’’ 89/392/EEC.

DIESEL FUEL Use No. 2 diesel fuel in the engine of this machine. The use of other fuels can cause the loss of engine power and high fuel consumption.

In very cold temperatures, a mixture of No. 1 and No. 2 diesel fuels is temporarily permitted. See the following Note.

NOTE: See your fuel dealer for winter fuel requirements in your area. If the temperature of the fuel is below the cloud point (wax appearance point), wax crystals in the fuel will cause the engine to lose power or not start.

Fuel Storage If you keep fuel in storage for a period of time, you can get foreign material or water in the fuel storage tank. Many engine problems are caused by water in the fuel.

Keep the fuel storage tank outside and keep the fuel as cool as possible. Remove water from the storage container at regular periods of time.

The diesel fuel used in this machine must meet the specifications in the chart below or Specification D975-81 of the American Society for Testing and Materials.

AIR CLEANER Service Interval The element must be cleaned or replaced when the warning lamp for the air cleaner is illuminated while the engine is running.

The dust cup must be cleaned after every 10 hours of operation or daily, whichever occurs first. If the machine is being operated in bad conditions, clean the dust cup several times during the period of operation.

Cleaning the Filter It is recommended that the filter be cleaned by washing.

Washing will remove more dirt than other methods of cleaning.

STEP 3 Connect the leads of an ohmmeter to the terminals on the air restriction indicator.

STEP 4 Actuate the manometer.

STEP 5 Turn the vacuum control until the ohmmeter indicates a complete circuit.

STEP 6 Read the manometer.

STEP 7 The indication must be 5.5 to 7.0 kPa.

Wash the filter in a detergent. Mix according to instructions on the container. Do not use water pressure over 206 kPa at the nozzle. Let the filter become completely dry before you install the filter. Do not use compressed air to dry the filter. If you use a drier, do not exceed 71° C and make sure that the air is circulating in the drier.

You can use compressed air to clean the filter, but this method is not the best method. Compressed air will not r e m ove t h e c a r b o n a n d s o o t . W h e n yo u u s e compressed air, do not use more than 206 kPa at the nozzle. Hold the nozzle 25 mm or more away from the filter. Apply compressed air to the inside of the filter only.

After the filter is clean and dry, check the filter. Put a lamp inside the filter and check for holes or splits in the pleats. Check for damage to the metal parts and rubber gasket. Replace the filter if the filter is damaged.

NOTE: Check a new filter the same way. Do not use a new filter that is damaged.

Checking the Switch for the Air Filter Warning Lamp (Air Restriction Indicator) STEP 1

STEP 8 If the air restriction indicator does not close at the specified vacuum, install a new air restriction indicator.

Safety Filter A safety filter is welded to the outlet of the air cleaner body. The restriction indicator is connected to the fitting.

The safety filter prevents air from entering the engine if the restriction indicator is damaged.

Safety filter will become plugged if a leak occurs in the restriction indicator. The restriction indicator will not work when the safety filter is very dirty.

Checking the Safety Filter STEP 1 Close the intake pipe on the air filter with a block of wood.

STEP 2 Have another person help with the following steps.

STEP 3 Pull the stop cable out until the stop cable stops moving. Hold the stop cable in this position until step 12 has been completed.

Remove the air restriction indicator.

STEP 4 STEP 2 Connect the air restriction indicator to a manometer.

Turn and hold the key switch in the START position for 15 seconds.

STEP 6

If the safety filter is very dirty, the air filter warning lamp will not illuminate.

If the safety filter is very dirty, remove the air cleaner body from the machine and try to clean the safety filter with compressed air. If the safety filter cannot be cleaned, the air cleaner body must be replaced.

SPARK ARRESTER MUFFLER The laws of some states and provinces make it necessary to install a spark arresting muffler on this machine. The spark arresting muffler has a pipe plug located on the bottom of the muffler.

Make sure the replacement muffler is a spark arresting muffler.

Clean the spark arresting muffler every 100 hours of operation.

STEP 1 Remove the pipe plug from the spark arrester muffler.

The pipe plug is made of brass, if a new pipe plug is needed, the new pipe plug MUST be made of brass.

STEP 2 Pull the stop control out.

STEP 3 Have another person use a block of wood to close the outlet of the muffler.

STEP 4 Hold the key switch in the START position for 30 seconds to remove the carbon from the muffler.

STEP 5 Install the pipe plug in the muffler.

STEP 6 Push the stop control in.

MAINTENANCE Electrolyte Level If the battery is a maintenance free battery, check the level of the electrolyte every 1000 hours of operation or six months, whichever occurs first. For all other batteries, check the level of the electrolyte every 250 hours of operation.

NOTE: A maintenance free battery will have the words Maintenance Free on the decal on the top of the battery.

If the center part of the decal has been removed for access to the battery caps, it is possible that the words Maintenance Free have been removed from the decal.

Check the level of the electrolyte more often during hot weather. The use of a large amount of water by the battery can be caused by high battery temperature or a voltage regulator setting that is too high. Keep the electrolyte level above the top of the plates in the battery at all times to prevent damage to the battery.

NOTE: On maintenance free batteries it is necessary to remove the center part of the decal for access to the battery caps. Do not discard the center part of the decal.

Install the center part of the decal after the battery caps have been installed.

If the level of the electrolyte is low, add distilled water or other clean water until the electrolyte is just below the cell opening. Do not add more water than is needed. Too much water can cause bad performance, a short service life, and corrosion around the battery.

NOTE: Add water only. DO NOT add electrolyte.

Inspecting and Cleaning a Battery If damage causes an electrolyte leak, replace the battery.

If the battery in your machine has nonspill caps, see Nonspill Caps on page 4005-4 and check the condition of the nonspill caps. See Specifications in Section 4002 to find if the battery in your machine must have nonspill caps.

Inspect the battery at regular intervals for dirt, corrosion, and damage. Electrolyte and dirt on the top of the battery can cause the battery to discharge by making a passage for the current to flow.

If the battery must be cleaned, remove the battery from the battery carrier and clean the battery, cable terminals, and the battery carrier. When available, use Case Battery Saver and cleaner according to the instructions on the container. Case Battery Saver and Cleaner also helps prevent corrosion. If Case Battery Saver and Cleaner is not available, use baking soda and water as a cleaner. DO NOT permit any type of cleaner to enter the cells of the battery.

Install the battery in the machine and make sure the fasteners are tight. Apply Case Battery Saver and Cleaner or Urethane Seal Coat to the cable ter minals to prevent corrosion. See the Parts Counter Catalog. DO NOT apply grease.

NONSPILL CAPS See Specifications in Section 4002 to find if the battery(ies) in your machine must have nonspill caps.

!

WARNING: If the battery(ies) in this machine must have nonspill caps, do not operate the machine if the nonspill caps do not work correctly, or if the nonspill caps are 48-99A not in place.

Do not operate the machine if the nonspill caps do not work correctly or if the nonspill caps are not in place. Nonspill caps prevent electrolyte leakage which can cause personal injury and damage to the machine if the machine turns over in an accident.

The nonspill caps have a valve with a stem made of lead and rubber. When the nonspill cap is turned upside down, the weight of the lead holds the rubber stem against the breather hole, preventing the loss of electrolyte.

If the breather hole and valve are closed by foreign material, pressure in the battery can become high enough to break the case of the battery. Always check the breather hole for foreign material when you check the electrolyte level. If there is foreign material over the breather hole, turn the nonspill cap upside down and clean the nonspill cap. Move the nonspill cap up and down rapidly. You must be able to hear the valve, wash the nonspill cap and loosen the valve. Move the nonspill cap up and down rapidly to remove the water.

When you remove a nonspill cap, check the condition of the rubber gasket. If the rubber gasket is gone or is damaged, install a new nonspill cap.

Missing or broken nonspill caps MUST be replaced with new nonspill caps. DO NOT use any other type of cap to replace nonspill cap.

When you install a new battery, the new battery MUST have nonspill caps. You can use the nonspill caps from the old battery if the nonspill caps are in good condition.

Visual Checks 1. Make sure the cable connections are clean and tight.

Clean foreign material from the top of the battery.

2. Inspect the battery case, battery posts, and cables for damage.

3. Check the electrolyte level. See page 4005-4.

4. If you added water to the battery, the battery must be charged for 15 minutes at 15 to 25 amperes to mix the water with the electrolyte.

790863A

Specific Gravity Check A hydrometer is used to check the specific gravity (weight) of the electrolyte. The specific gravity is an indication of the level of charge for each cell.

1. Temperature in ° F 2. Temperature in ° C Specific Gravity Chart

Hydrometers are made to show the correct specific gravity when the temperature of the electrolyte is 26.7°C.

4. Make a record of the corrected specific gravity reading for each cell.

When you check the specific gravity, you must know the temperature of the electrolyte. If your hydrometer does not have a ther mometer, get a ther mometer to check the temperature of the electrolyte. The thermometer must indicate a high temperature of at least 52°C.

5. If the difference between the high reading and the low reading is .050 or more, charge the battery and check the specific gravity again. If after charging, the difference is still .050 or more, install a new battery.

1. Remove enough electrolyte from a cell so that the float is free in the tube.

NOTE: If the specific gravity cannot be checked without first adding water to the cell, the battery must be charged for 15 minutes at 15 to 25 amperes to mix the water with the electrolyte. Then check the specific gravity.

6. The corrected specific gravity reading shows the level of charge for the cell. The level of charge must be at least 75% in each of the cells. In maintenance free batteries the level of charge is at least 75% if the corrected specific gravity reading is 1.240 or higher. In all other batteries the level of charge is at least 75% if the corrected specific gravity reading is 1.230 or higher.

2. Read the float.

7. If the difference between the high reading and the low reading is less then .050, and the level of charge is at least 75% in all of the cells, do the Capacity (Load) Test.

3. Read the thermometer. If the reading is above 26.7° C add specific gravity points to the reading for specific gravity. If the reading is below 26.7° C subtract specific gravity points from the reading for specific gravity. See the following illustration and add or subtract specific gravity points as needed.

8. If the difference between the high reading and the low reading is less than .050, but the level of charge is less than 75% in any of the cells, charge the battery and check the specific gravity again. If after charging: A. The level of charge is less than 75% in any of the cells, discard the battery.

B. The level of charge is at least 75% in all of the cells, do the Capacity (Load) Test.

Capacity (Load) Test This test can be done using a variable load tester. Connect the test equipment according to the instructions of the manufacturer of the equipment.

1. The level of charge of the battery must be at least 75%.

Do the Specific Gravity Check in this section.

2. Prepare the tester for the test.

NOTE: Never apply a load for longer than 15 seconds.

After each 15 seconds, turn the load control knob to OFF for at least one minute.

4. Apply a 15 ampere load to the battery for 15 seconds.

Wait at least three minutes before continuing with the test.

5. Check and make a record of the temperature of the electrolyte.

A. Select the voltmeter range that will measure 1 to 18 volts.

6. Find the correct load for this test in Specifications in Section 4002.

B. Make sure the load control knob is in the OFF position.

NOTE: The correct load is half of the cold cranking amperes at -17°C.

C. Select the ammeter range that will measure 0 to 1000 amperes.

7. Turn the load control knob until the ammeter indicates the specified load. Keep the load for 15 seconds and read the voltmeter. Turn the load control knob to OFF.

D. Move the volt lead switch to the INT. position.

8. Compare the test reading and the temperature of the electrolyte to the chart below.

3. Connect the tester to the battery as shown.

CHARGING A BATTERY The charging rate must be decreased if:

!

WARNING: Never try to charge the battery if the electrolyte in the battery is frozen. 47-83A

Before you charge the battery, check the level of the electrolyte.

It is difficult to give an exact charging rate because of the following var iable conditions: (1) temperature of the electrolyte, (2) level of charge, and (3) condition of the battery. Use the charging guide for the correct charging rate and time.

1. Too much gas causes the electrolyte to flow from the cells.

2. The temperature of the electrolyte rises above 52°C. NOTE: For the best charge, use the slow charging rates.

The battery is fully charged when, over a three hour period at a low charging rate, no cell is giving too much gas, and the specific gravity does not change.

IMPORTANT: There is no charge pump on this machine. Charge oil for the closed loop hydrostatic system is supplied by return oil from the gear pump hydraulic system. DO NOT run the engine if the return oil from the gear pump hydraulic system is not providing adequate charge oil flow. DO NOT make any test connections or flowmeter connections which will prevent the flow of this return oil/charge oil.

HYDROSTATIC START-UP PROCEDURE Do this procedure any time the hydraulic oil has been removed from the piston pumps.

6. Connect a pressure gauge with a capacity of at least 28 bar to the test port.

1. If necessary, fill the reservoir to the correct level. See Section 1002 for the correct hydraulic oil.

7. Start and run the engine at low idle. Observe the indication on the pressure gauge to make sure the piston pumps have charge pressure. Operate at low idle for a few minutes to allow the air to escape from the closed loop system.

2. Change the hydraulic filter.

3. Remove the socket head plug from the top of each piston pump housing. This will allow the air to bleed out as the piston pump fills with hydraulic oil.

4. When the oil level in each piston pump is at the bottom of the hole for the socket head plug, install the socket head plugs.

5. Find the elbow connected to the outlet port of the hydraulic filter. Remove the 1/8 inch NPT pipe plug from the test port in the elbow.

8. Run the engine at full throttle. Read the pressure gauge and record the charge pressure indication. Stop the engine.

9. The pressure indication must be at least 9.0 bar at full throttle. If the pressure indication is not correct, see Section 6002 for testing and adjusting the charge pressure.

CHARGE PRESSURE TEST IMPORTANT: There is no charge pump in the piston pumps. DO NOT run the engine if the return oil from the gear pump hydraulic system is not providing adequate charge oil flow.

1. Find the elbow connected to the outlet port of the hydraulic filter. Remove the 1/8 inch NPT pipe plug from the test port in the elbow.

2. Connect a pressure gauge with a capacity of at least 28 bar to the test port.

3. Run the engine at full throttle. Read the pressure gauge and record the charge pressure indication. Stop the engine.

4. The charge pressure must be 9.0 bar minimum at full throttle. If the charge pressure is correct, go to step 7. If the charge pressure is low, do steps 5 and 6 as necessary.

5. If the charge pressure is low, remove and inspect the parts of the charge relief valve. Repair or replace the charge relief valve as necessary. You can connect the vacuum pump to the hydraulic reservoir to hold the hydraulic oil when the charge relief valve is removed.

6. If the parts of the charge relief valve are good, add shims from the shim kit to adjust the charge pressure. A shim with a thickness of 0.25 mm will increase the charge pressure 0.5 bar. Continue to adjust the charge relief valve and to check the charge pressure until the charge pressure is as specified in step 4. Then go to step 7.

7. Raise the machine until the tires are off the floor. Use acceptable supports to hold the machine off the floor.

8. Start the engine and run the engine at low idle. Raise the seat bars and pull up the knob on the parking brake switch (Engaged position).

9. Run the engine at full throttle. Slowly push the direction control levers forward just enough to load the hydrostatic system against the parking brake without decreasing the engine speed. Read the pressure gauge. The pressure must be within 2.1 bar of the pressure in step 3 (or the pressure in step 6, if you did step 6).

10. Run the engine at full throttle. Slowly push the direction c o n t r o l l eve r s r e a r wa r d j u s t e n o u g h t o l o a d t h e hydrostatic system against the parking brake without decreasing the engine speed. Read the pressure gauge.

The pressure must be within 2.1 bar of the pressure in step 3 (or the pressure in step 6, if you did step 6).

11. If the pressure is not correct in step 9 or step 10, there is too much leakage in the hydrostatic system. See page 9 and do the leakage test for the drive motors to determine which components need repair.

Read the disassembly and assembly instructions completely before you begin these procedures.

BP96F003

Be careful so that you do not damage parts that have machined surfaces.

INSPECTION

Use new seals and O-rings during assembly.

When you assemble the motor, make sure that the bench, the tools, and your hands are clean.

STEP 1

Do not use shop cloths to dry the parts. Use compressed air or towels that are free of lint.

Clean all parts in cleaning solvent. Do not use shop cloths to dry the parts. Use compressed air or towels that are free of lint.

If possible, assemble the motor in an area that is free of dust.

STEP 2 Inspect the contact areas where the rotor and the rollers touch the brake housing and the distributor plate. Check for wear, scoring, and grooves.

STEP 5 Check the outer friction discs for wear and distortion. Check the inner friction discs for wear and distortion, especially in the spline area.

STEP 3 Inspect the rollers and the lobes on the rotor for pitting, scoring, and grooves. If you find any of these defects, install a new gear set.

STEP 6

STEP 4

STEP 7

Inspect the spool for scoring and grooves. If you find either defect, install a new spool.

Before assembly, use clean hydraulic oil to lubricate all metal parts. Use petroleum jelly (vaseline) to lubricate all rubber parts.

Check the brake springs for cracks, distortion, and other damage.

WARNING: Two persons are required to perform the flowmeter tests for safety to avoid possible injury. One person must be seated in the operators seat with the Seat Bar down when the engine is running. The second person is to control the CSM118 flowmeter and take the readings.

8. Divide the flow reading at 138 bar by the flow reading in step 5. This answer multiplied by 100 is the percent efficiency of the pump. If the efficiency of the pump is less than 75%, repair or replace the pump. If the efficiency of the pump is more than 75%, the pump is good.

2 1. Park the machine on a level surface. Lower the loader bucket to the floor. Stop the engine.

1 2. See the illustration. Disconnect the hose from the 45 degree fitting at Test Point 2. Install a plug in the hose.

Connect the flowmeter inlet hose to the 45 degree fitting (1-1/16 - 12 JIC).

3. See the illustration. Find the return tube from the loader control valve. Remove the cap from the fitting on the return tube. Connect the flowmeter outlet hose to the fitting (7/8 - 14 JIC).

GENERAL INFORMATION Contamination in the hydraulic system or hydrostatic system is a major cause of malfunction of components.

Contamination is any foreign material in the hydraulic oil.

Contamination can enter the hydraulic and hydrostatic system in any of the following ways: 1. When you drain the hydraulic oil or disconnect a line.

2. When you disassemble components.

hydraulic

or

hydrostatic

3. From normal wear of the components.

4. From damaged components.

The best way to remove contamination from the hydraulic system is to use the por table filter. See Cleaning the Hydraulic System beginning on page 4.

T h e b e s t way t o r e m ove c o n t a m i n a t i o n f r o m t h e hydrostatic system is to disassemble the components and clean the system. See Cleaning the Hydrostatic System beginning on page 6.

TYPES OF CONTAMINATION There are two types of contamination, microscopic and visible. Microscopic contamination occurs when very fine particles of foreign material are in suspension in the hydraulic oil. These particles are too small to see or feel. Mircroscopic contamination can be found by the identification of the problems the microscopic contamination causes, or by testing in a laboratory. Examples of problems caused by microscopic contamination include the following:

Visible contamination is foreign material that can be found by sight, touch, or odor. Visible contamination can cause a sudden failure of a component. Examples of visible contamination include the following: 1. Particles of metal or dirt in the oil.

2. Air in the oil.

1. Cylinder rod seals leak.

3. Odor of burned oil.

2. Control valve spools do not return to neutral.

4. Water in the oil.

3. The hydraulic system has a high operating temperature.

4. Rapid wear of the components.

ACCIDENT DAMAGE TO ROPS CANOPY If the machine has rolled over or the ROPS canopy has been in some type of accident (such as hitting an overhead object during transport), you must replace the ROPS canopy to have the same protection you had with the original ROPS canopy.

After the accident check for damage to the ROPS canopy, seat belt, accessories, and wiring in the ROPS canopy.

Before operating the machine, replace all damaged parts.

Do not try to weld or straighten the ROPS canopy.

MAINTENANCE AND INSPECTION OF ROPS CANOPY After every 500 hours of operation or every six months, whichever occurs first, do the following: 1. Check the torque for the mounting bolts for the ROPS canopy. See the illustration on page 4 for torque specifications.

!

WARNING: Do not install attachments that will make the total weight of the machine more than the weight shown in the maximum gross vehicle weight section of the ROPS serial number plate.

47-26

!

WARNING: Do not change the ROPS in any way. Changes made to the ROPS which are not authorized, such as welding, drilling or cutting will make the ROPS weaker and decrease your protection. Replace the ROPS if it becomes damaged in any way.

DO NOT TRY TO MAKE REPAIRS TO THE ROPS. 47-25

2. Check the torque for the mounting bolts for the seat belts.

See the illustration on page 5 for torque specifications.

3. If a seat belt is damaged in any way, replace the seat belt.
