SAFETY INSTRUCTIONS The GROUNDSMASTER® 325-D 4 WHEEL DRIVE was tested and certified by TOR for compliance with the specifications of the American National Standards Institute. Although hazard control and accident prevention partially are dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
SAFETY INSTRUCTIONS WHILE OPERATING 16. Using the machine demands the operator's complete attention, To prevent kiss of control: A. Operate only in daylight or when there is good artificial light, B, Drive slowly, C. Avoid sudden stops and starts. D. Look behind machine before backing up. E. Watch for holes or other hidden hazards. F. Do not drive close to a sand trap, ditch, creek; or hazard: G. Reduce speed when making sharp turns and when rutting on a hillside. H.
SAFETY INSTRUCTIONS 36. Make sure all hydraulic line connectors are tight, and all hydraulic hoses and lines are in good condition before applying pressure fo the system. 37. Keep body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure., Use paper or cardboard, not hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin and do serious damage.

SET-UP INSTRUCTIONS CHECK TORQUE OF FRONT WHEEL NUTS A\ warning Tighten front wheel nuts to 45-55 ft—Ib {61-75 N -m) after 1-4 hours of operation and again after 10 hours of operation and every 250 hours thereafter. Failure to maintain proper torque could result in failure or loss of wheel and may result in personal injury. GREASE TRACTION UNIT Before the machine is operated, it must be greased to assure proper operating characteristics; refer to Lubrication Maintenance.
BEFORE OPERATING Figure 19 1. Oil fill hole IMPORTANT: Check level of oil after every 5 hours of operation or daily. Change oil and filter after initial 50 hours and every 100 hours thereafter. Change oil and filter more frequently when engine is operated in extremely dusty or dirty conditions. 6. Install dipstick into tube. FILL FUEL TANK WITH DIESEL FUEL The engine runs automotive type diesel fuel with a minimum cetacean rating of 40.
BEFORE OPERATING CHECK COOLING SYSTEM Clean debris off screen and font of radiator daily, hourly if conditions are extremely dusty and dirty; refer to Cleaning Radiator and Screen The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti—freeze. Check level of coolant at beginning of sate day before starting the engine. Rapacity of cooling system is approximately 6 quarts (5.7 L), 1. Carefully remove radiator cap.
BEFORE O Figure 22 2. Mounting Bolts 1. Check Plugs (3) CONT Traction Pedal (Fig. pedal has two functions; one is to make the machine move forward, the other is to make it move backward. Using the heel and toe of the right foot, depress top of pedal to move forward and bottom of pedal to move backward. Ground speed is proportionate to how far pedal is depressed. For maximum ground speed with no load, traction pedal must be fully depressed while throttle is in FAST position.
CONTROLS Tilt Steering Control (Fig. on right side of steering column, Pull lever rearward to adjust steering wheel to desired fore or aft operating position and push lever forward to lock adjustment. Brake Pedal {Fig. the engine is shut off, the parking brake must be engaged to prevent accidental movement of the machine. The hydro static transmission will not, at any time, act as a parking brake for the machine.
CONTROLS IMPORTANT: If the switch must be overridden because of an emergency, the engine can be started and will continue 1o run while reset button is held in. Glow Plug Switch and Indicator (Fig. to preheat engine cylinders before and during starting procedures. Push switch lever upward and hold while watching indicator. Indicator glows red when sufficiently heated. Length of time necessary to preheat cylinders should be determined by atmospheric temperature; refer to Starting/Stopping Engine.
CONTROLS Seat Adjusting Lever (Fig. adjust standard seat, push lever backward and slide seat to the desired position. Release lever to lock seat in place. The suspension seat may be adjusted forward or rearward by pulling out the lever at the left side of the seat, sliding the seat to the desired position, and releasing the lever. The weight adjustment knob may be adjusted for any operator's comfort. ‘ Figure 20 1.
OPERATING INSTRUCTIONS BLEEDING FUEL SYSTEM 1. Unlatch and raise hood over engine. 2. Loosen air bleed screw on top of fuel filter/water separator {Fig. 30}. Figure 30 1.
