Installing the Ball Joint and Connecting the Lift Cylinder Installing the Battery in the Chassis Note: Ball joints are not required for all implements; refer to implement operator’s manual for requirements. 1. Thread jam nut fully onto right-hand ball joint. 2. Screw ball joint into right hand push arm until center of ball joint is 2-3/8 in. (60 mm) away from front of push arm (Fig. 12).
Checking the Tire Pressure 6. Raise front of lift arm until hole in movable end of cylinder lines up with holes in lift arm brackets. Use caution as lift arm is spring-loaded. Hold parts together with cylinder pin, spring pin, and cotter pin. Cotter pin must be to the outside. The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. Correct air pressure in the front and rear tires is 21 psi (145 kPa).
Check Engine Oil 1. Mounts weights to rear of traction unit with 2 capscrews (1/2 x 2-3/4 in.), lock washers, flat washers, and spacers (Fig. 14). Position the flat washer and spacer between weight and chassis with flat washer against weight. The engine is shipped with 4 qt (3.8 l) of oil in the crankcase; however, level of oil must be checked before and after the engine is first started. 1. Park machine on a level surface, stop engine and remove key from ignition switch. Open hood and install hood prop.
Filling the Fuel Tank Caution Danger • If engine has been running, pressurized hot coolant can escape when radiator cap is removed and cause burns. Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. 1. Check level of coolant in expansion tank. Coolant level should be between the marks on side of tank.
Note: Do not mix engine oil and automatic transmission fluid or hydraulic system component damage may result. When changing fluids, also change transmission filter. Do not use Dexron II ATF. Important When adding oil to the hydraulic system, use a funnel with a fine wire screen—200 mesh—and ensure funnel and oil are immaculately clean. This procedure prevents accidental contamination of the hydraulic system.
The hydrostatic transmission will not, at any time, act as a parking brake for the machine. To engage parking brake, push down fully on brake pedal and pull parking brake knob out; then release the pedal. To release parking brake, depress brake pedal until parking brake knob retracts. To stop quickly, remove right foot from traction pedal and depress the brake pedal. To permit straight stops, brake cables must be evenly adjusted.

Key Switch Refer to Bleeding The Fuel System. Three positions: OFF, ON / Preheat and START. (Fig. 23). 1. Ensure parking brake is set, PTO switch is in OFF position and lift lever is in TRANSPORT or FLOAT position. Remove foot from traction pedal and insure it is in neutral. Throttle Control The throttle (Fig. 23) is used to operate engine at various speeds. Moving throttle forward increases engine speed—FAST; backward decreases engine speed—SLOW.
Checking the Interlock Switches Danger Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. Caution If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills.
are the transmission, engine speed, load on the cutting blades or other implement components, and the importance of the brakes. 5. Engage the parking brake. Depress the traction pedal while engine is running and the PTO lever is disengaged. The engine should stop within 2 seconds. If engine stops, the switch is operating correctly; thus, continue operation. If engine does not stop, there is a malfunction in the interlock system that should be corrected before beginning operation.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 10 hours • • • • After first 50 hours • Change the engine oil filter. • Check engine RPM.

Daily Maintenance Checklist Duplicate this page for routine use. For the week of: Maintenance Check Item Mon. Tues. Wed. Thurs. Check safety interlock operation. Check that the grass deflector is in the down position. Check brake operation. Check the engine oil level. Check the cooling system fluid level. Drain the water/fuel separator. Check the air cleaner. Check the radiator and screen for debris. Check unusual engine noises.1 Check the transmission oil level. Check the hydraulic hoses for damage.
Lubricating the Machine The traction unit must be lubricated regularly. If machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation or whenever water is used to clean machine. 1. The traction unit bearings and bushings that must be lubricated are: PTO shaft and yokes (Fig. 27); lift arm pivots (Fig. 27); right and left push arm ball joints (Fig. 27); push arm pivot bushings (Fig. 28); PTO pivot housing blocks (Fig. 29); brake pivot bushings (Fig.
General Air Cleaner Maintenance 1. Check air cleaner body for damage which could possibly cause an air leak. Replace a damaged air cleaner body. 2. 2. Service the air cleaner filters when air cleaner indicator (Fig. 33) shows red or every 400 hours (more frequently in extreme dusty or dirty conditions). Do not over service air filter. 1 1 Figure 35 1. Primary filter 3. Inspect primary filter and discard if damaged. Do not wash or reuse a damaged filter. Figure 33 1.
Note: This situation may be particularly prevalent if the rear discharge cutting unit is being used. The front of the radiator can be cleaned thoroughly by blowing with compressed air from the fan side of the radiator. Make sure to clean out any debris that settles to the bottom of the screen. The screen in front of radiator can be removed—by loosening wing nuts at top of screen—to make cleaning easier. 6. After oil is drained, reinstall drain plug and wipe up any oil that is spilled. 7.
Bleeding Air From Injectors Note: This procedure should be used only if fuel system has been purged of air through normal priming procedures and engine will not start; refer to Bleeding Fuel System. 1 1. Loosen the pipe connection to the No. 1 injector nozzle and holder assembly at injection pump (Fig. 40). 2 Figure 38 1. Water separator 2. Drain plug 1 Replace filter canister after every 400 hours of operation. 1. Clean area where filter canister mounts. 2.
Changing Coolant In Cooling System Capacity of cooling system is approximately 6 quarts (5.7 L). The cooling system must be filled with a 50/50 solution of water and permanent ethylene glycol anti–freeze. Every two years, drain the coolant from the radiator by opening the drain cock (Fig. 41). After coolant is drained, flush the entire system and refill it with a 50/50 solution of water and anti–freeze. 1 Figure 43 1.
Cooling Fan Belt 5. Install fan belt guard and secure with capscrews (Fig. 45). Close and latch hood. 1. Unlatch and open hood. To replace belt: 2. Remove capscrews (5) securing fan belt guard and remove guard (Fig. 45). 1. Follow procedures in step 1 and 2 above. 2. Loosen locknut securing adjustable idler pulley, slide pulley away from belt, and remove belt from pulleys (Fig. 46). 3. Install new belt and adjust for proper tension.
Adjusting the Traction Drive for Neutral 1. Park vehicle on a level surface and turn engine off. Apply the parking brake, tip seat forward, and actuate pump lever (Fig. 50) to ensure assembly is properly seated and operating freely. Correct any discrepancy. 2. Block right front tire and both rear tires so vehicle cannot roll forward or backward. 1 3. Jack up frame so left front wheel is off the shop floor. Use a jack stand to support the frame. 2 4.
2. Move PTO lever forward to ON position. 10. Release parking brake; then check left front wheel that is off shop floor. Wheel must not be rotating. If wheel is rotating, proceed to step 11 for an adjustment. If wheel is not rotating, proceed to step 13. Verify the adjustment with throttle in SLOW and FAST position. 3. Remove boot from button end of PTO switch (Fig. 51). Retain boot for reinstallation. Separate switch wire connectors. 11. Because the wheel is rotating, the pump plate must be adjusted.
5. Connect a continuity tester or ohm meter to switch harness connector. With parking brake engaged, the switch circuit should not have continuity. If there is continuity, recheck switch or switch installation. 5. Move PTO lever to OFF position and install instrument cover. 3 Adjusting the Tilt Steering Control 2 If steering wheel tilt control lever must be adjusted, proceed as follows: 1 1. Remove knob from parking brake and self tapping screws from steering column cover.
Adjusting the Brakes 3. When rear wheels are adjusted correctly, tighten jam nuts against tie rods. Adjust the service brakes when there is more than 1 in. (25 mm) of “free travel” of the turn pedals, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt. The brakes should only need adjusting after considerable use. These periodic adjustments can be performed where the brake cables connect to the brake pedal mount.
hydraulic system to overheat. When lift lever latch is adjusted correctly, the lift lever should just clear the rounded part of the latch as lever is moved into FLOAT position. 1. Unscrew ball from lift lever. 2. Remove self tapping screws and lift cover off lift lever to expose the latch. 3. Loosen two capscrews on top of the lift lever latch (Fig. 60). Place lever on rounded tip of latch (Fig. 60), and slide latch w/lever forward until stopping resistance is felt.
3. Install filter by hand until gasket contacts mounting head. Then rotate an additional 1/2 turn. Note: Do not mix engine oil and automatic transmission fluid or hydraulic system component damage may result. When changing fluids, also change transmission filter. Do not use Dexron II ATF. 4. Start engine and check for hydraulic oil leaks. Allow engine to run for about two minutes so any air in the system is purged (removed).
Servicing the Battery 9. Leave machine set for two additional minutes, then remove dipstick and check oil level in axle (Fig. 63). If level is low, add oil until level matches groove in dipstick (Fig. 63). If level is too high, remove drain plug (Fig. 62) and drain oil until oil level matches groove in dipstick. Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm.
