DRIVE WHEEL CHAIN
(Refer to the “Front Wheel Group” in the parts listing)
The drive wheel chain transfers power from the motor
to the drive wheels. Check the chain condition and
tension every 200 hours or operation. The chain
should deflect 1/2 in (13 mm). Lubrication of drive
chain is not recommended. Clean dirt and grease
build up from chain to eliminate the abrasive effects.
ADJUSTING THE DRIVE WHEEL CHAINS
1. Turn off machine with key switch and set parking
brake.
FOR SAFETY: Before leaving or servicing
machine; Stop on level surface, set parking
brake, turn off machine and remove key.
2. Loosen the bolts on the drive motor.
3. Slide the motor to adjust tension.
4. Tighten motor mounting bolts.
BRAKES
(Refer to the “Brake Group” in the parts listing)
The brake pedal and the parking brake operate the
self-centering front wheel disc brake. With the
parking brake set, the brake should hold machine
from moving with full throttle in either forward or
reverse. This brake check should be preformed in
the pre-run check before each days operation. The
disc and caliper should be inspected every 200 hours
of operation. The brake should be adjusted so that
the disc pads are as close to the disc as possible,
without causing brake to drag.
FOR SAFETY: Before leaving or servicing
machine; Stop on level surface, set parking
brake, turn off machine and remove key.
