ADJUSTMENTS

WHEEL ‘CREEP’
‘Creep’ is when the engine is running and the hydrostatic transmission is in neutral, but due to inadequate
alignment wheels still move. To stop this motion do the following procedure.
1. Lift up and support the unit so rear wheels are off the ground, and block front wheels.
2. In the rear of the engine, on the hydrostatic transmission is
the idler arm. The idler arm rests on the idler pulley. The
idler pulley rests in the ‘V’ shape of the shift arm.
3. Loosen the bolt and nut holding the idler pulley to
the idler arm. Leave it finger tight.
4. With the engine running, slide the pulley in the
idler arm slot until it centers on the shift arm
on the hydrostatic and the wheel ‘creep’
stops.
5. Tighten all fasteners and test by using the foot
pedal linkage to see that the ‘creep’ is re-
moved.
6. Turn the engine off and lower the machine.
STORAGE
To prevent damage from freezing, pour window washer fluid into spray systems tank and
operate pump to circulate mix through gun and hose back to tank. Open boom control to
circulate through rest of spray system.

1. While engine is running, treat upper cylinders by spraying engine fogging agent into the air intake (NOT
through air cleaner) for about two minutes. Fogging agent can be obtained from your local after market
supplier. Open throttle for short burst of speed, shut off ignition and allow engine to come to a stop while
continuing to spray fogging agent into air intake.
2. Leave spark plugs in holes or seal spark plug holes with suitable threaded metal plugs and cover all
openings into engine with suitable non-hygroscopic material.
3. Check coolant protection. Store machine indoors in dry area.
