ADJUSTMENTS
WHEEL ‘CREEP’ ADJUSTMENT
‘Creep’ is when engine is running and hydrostatic transmission is
in neutral, but due to inadequate alignment, wheels still move. Do
the following procedures to stop this motion.
1. Lift up and support machine so all wheels are off the ground
and can turn freely.
2. On the side of the pump there is a Creep Arm. Loosen bolts.
3. With engine running adjust the creep arm up or down in slot
so centering arm centers on the swash plate.
4. Tighten all fasteners and test by using foot pedal linkage to
see that the "creep" is removed.
5. Turn engine off and lower machine.
TO ADJUST FOOT PEDAL THROTTLE CABLE
1. Jack up unit so that all drive wheel are off the ground. (Use jack stands)
2. Start the engine, make certain that the hand throttle is in the idle position (1200 engine RPM).
3. Engine speed must increase as soon
as the foot pedal begins to move in
either direction. At the full forward
position, the engine RPM must be
3600 RPM ± 100.
4. Minor adjustment can be made by
backing out (unscrewing) Retainer (Ref
A) until you reach full engine RPM with
the foot pedal fully depressed in the
forward position. Be sure to recheck
after the nuts are fully tightened.
5. Major adjustment needs to be made at
(Ref B) by pulling the slack out of the
cable. Loosen the screw in the wire
block that is clamped onto the end of
the cable and sliding it up to the cable
block that is through the throttle plate.
Do not let the throttle plate move to
increase idle speed. Tighten the screw.
6. Test run to determine that there is no binding and that engine idle speed is 1200 RPM and that it is 3600
RPM at full forward position of the foot pedal.
