SAFETY INSTRUCTIONS The GROUNDSMASTER 325ĆD 4 WHEEL DRIVE was tested and certified by TORO for compliance with the B71.4Ċ1990 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.
Using the machine demands the operator's complete attention. To prevent loss 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 turning on a hillside. H.
% ! Make sure all hydraulic line connectors are tight, and all hydraulic hoses and lines are in good condition before applying pressure to the system. 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.

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. The traction unit bearings and bushings that must be lubricated are: PTO shaft and yokes (Fig. 34); lift arm pivots (Fig. 34); right and left push arm ball joints (Fig. 34); push arm pivot bushings (Fig. 35); PTO pivot housing blocks (Fig. 36); brake pivot bushings (Fig.

Remove boot from button end of seat switch (Fig. 41). Retain boot for reinstallation. Separate switch wire connectors. Install new seat switch to support bracket. Adjust switch height so it is 3/32" (2.4 mm) below top of spring pin.
Remove boot from button end of PTO switch (Fig. 42). Retain boot for reinstallation. Separate switch wire connectors. Assure hose between air cleaner and carburetor is clamped securely in place. Replace the hose if it is cracked or punctured. Check air cleaner body for dents and other damage which could possibly cause an air leak. Replace a damaged air cleaner body. Be sure dust cap is sealing around bottom of air cleaner body.
Service the air cleaner filter every 250 hours or more frequently in extreme dusty or dirty conditions by washing or using compressed air. Replace the element after every six cleanings (1500 hours) or annually, whichever comes first. Remove and service dust cup; refer to Servicing Dust Cup and Baffle. Remove wing nut w/gasket and slide filter element out of air cleaner body (Fig. 44).
Check oil level after each day's operation or each time machine is used. Change oil and filter after first 50 hours operation and every 100 hours thereafter. However, change oil more frequently when engine is operated in dusty or sandy conditions. If possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil.
Fuel pump is located on inner frame bulkhead to left of drive coupling assembly (Fig. 48). Bleed the fuel system; refer to Bleeding Fuel System. )-# This procedure should be used only if fuel system has been purged of air through normal priming procedures and engine still will not start; refer to Bleeding Fuel System Loosen the pipe connection to the No. 1 nozzle and holder assembly. Move throttle control to full FAST position.

Push idler pulley against belt until proper deflection is achieved and tighten idler pulley locknut (Fig. 51).
Press down on front of traction pedal and check travel. There should be approximately 3.50" clearance between end of pedal and floor plate when pedal in fully depressed (Fig. 53). Adjust pump control rod (Fig. 54) to attain dimension. Park vehicle on a level surface and turn engine off. Apply the parking brake, tip seat forward, and actuate pump lever (Fig. 55) to insure assembly is properly seated and operating freely. Correct any discrepancy.

After attaining desired adjustment, tighten screw on tie rod clamp and resecure ball joint to mounting bracket. 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.
when the implement is in the FLOAT position. This causes oil in the 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. Unscrew ball from lift lever. Remove self tapping screws and lift cover off lift lever to expose the latch. Loosen two capscrews on top of the lift lever latch (Fig. 63). Place lever on rounded tip of latch (Fig.
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). Shut engine off and check level of hydraulic system; refer to Check Hydraulic System Oil. +/$ Fluid to operate the power steering is supplied by the hydraulic system transmission charge pump. Cold weather start-up may result in stiff" operation of the steering until the hydraulic system has warmed up.
