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.
# Before disconnecting or performing any work on the hydraulic system, all pressure in system must be relieved by stopping engine and lowering implement to the ground. If the engine must be running to perform maintenance or an adjustment, keep clear of PTO shaft, cutting unit blades, and other moving parts. Do not overspeed the engine by changing the governor settings. Maximum engine speed with no load is 3300 rpm.

Reach in and rotate by-pass valve on transmission (Fig. 10) counterclockwise 1/2 to 1 turn. Opening the valve opens an internal passage in the pump, thereby bypassing transmission oil. Because fluid is by-passed, the machine can be pushed without damaging the transmission. When battery is fully charged, disconnect charger from electrical outlet and battery posts.

Another characteristic to consider is the operation of the turning pedals that are connected to the brakes. The brakes can be used to assist in turning the machine. However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. Another benefit of the turning brakes is to maintain traction. For example: in some slope conditions, the uphill wheel slips and loses traction.

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. 24); lift arm pivots (Fig. 25); right and left push arm ball joints (Fig. 24); push arm pivot bushings (Fig. 26); PTO pivot housing blocks (Fig. 27); brake pivot bushings (Fig.
(&1.$ (&1.$ Remove instrument cover and negative battery cable from battery. disconnect Pivot seat forward and secure with support rod to prevent it from falling accidentally and possibly causing injury. Remove boot from button end of seat switch (Fig. 31). Retain boot for reinstallation. Separate switch wire connectors. Connect a continuity tester or ohm meter to switch connector.
Connect a continuity tester or ohm meter to switch connector. With PTO lever in the ON position the switch circuit should not have any continuity. If there is continuity, recheck switch installation. If there is no continuity, proceed to next step. Move PTO lever to the OFF position. When PTO lever is in its normal, released position, the PTO switch should have continuity. If there is no continuity, recheck switch installation.
Inspect air cleaner and hose periodically to maintain maximum engine protection and to ensure maximum service life. 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.

Check tension of all belts initially after the first day of operation and every 100 hours thereafter. ,3&1."3/1 &,3 A new alternator belt (Fig. 36) is to be tensioned to 65 lbs. A used belt is to be tensioned to 40 lbs. To adjust belt tension, loosen upper and lower nuts securing idler arm to front engine mount (Fig. 37). Pull out on idler arm until desired belt tension is achieved. Tighten mounting nuts to secure adjustment.
ENGINE MAINTENANCE ADJUSTING GOVERNOR 1. With engine shut off, move throttle control to FAST position and open hood. Check between the throttle arm and the stop on the carburetor base to make sure there is 1/32" (0.8 mm) gap (Fig. 38). If gap is not correct, adjust throttle rod (Fig. 38) by turning ball joint ends until gap is 1/32" (0.8 mm). If gap is correct, proceed to step 2. WARNING Engine must be running so final adjustĆ ment of the governor can be performed.
,0" If the throttle control on the instrument panel will not stay in the FAST position during operation, remove the panel cover and tighten the nut and capscrew at base of throttle lever assembly. The governor is shipped with oil in it, but the level of oil must be checked after every 250 hours of operation. Position machine on level surface and shut engine off. Disengage hood latch and open the hood. Clean area around check plug on governor (Fig.
Check traction drive neutral position to assure front wheels do not creep; refer to Adjusting Traction Drive for Neutral. Loosen two nuts securing traction pedal shaft on right side of pedal (Fig. 42). 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. 41). Adjust pump control rod (Fig.
! ! # ! Should front wheel continue to rotate, check for the following: . Ball bearing is loose or worn out (Fig. 43). Plunger on interlock switch is sticking. . Loose or missing fasteners. Worn roll pin securing pump lever to transmission. . Pump lever loose on control shaft. (Correct by applying Loc-tite 271 or 601 to shaft.) Weak or damaged leaf springs (Fig. 43). Replace. Internal transmission component malfunction. Contact your local Toro distributor for assistance.
If steering wheel tilt control lever must be adjusted, proceed as follows: Remove knob from parking brake and self tapping screws from steering column cover. Slide cover up steering shaft to expose pivot bracket (Fig. 45). Loosen small nut, rotate pivot bracket until it tightens large nut below (Fig. 45). Retighten small nut. Reinstall steering column cover and parking brake knob.
Adjust the service brakes when there is more than one inch (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.
A lift lever latch that is positioned incorrectly can cause the lift lever to hold the spool in an actuated position 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.
%) 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. Using proper weight hydraulic oil in system minimizes this condition. The axle housing acts as the reservoir for the system. The transmission and axle housing are shipped from the factory with approximately 5 quarts (4.7 L) of SAE 10WĆ30 engine oil.
The Groundsmaster 345 has two identification numbers: a model number and a serial number. These numbers are stamped into a plate located on front bulkhead left of seat. In any correspondence concerning the unit, supply the model and serial numbers to ensure correct information and replacement parts are obtained. To order replacement parts from an authorized TORO Distributor, supply the following information: Model and serial numbers.
