Brake
Fully raising or lowering the control handle will ap-
ply an electrical brake that is mounted on the drive
motor. See Figure 10. When the brake is applied, a
switch disconnects the power to the traction circuit.
When the control handle is released from the oper-
ating position, it will automatically return to the
vertical position and apply the brake.

Tires and Wheels
CAUTION
If the drive wheel has been removed and installed,
check all wheel bolts after 2 to 5 hours of opera-
tion. Tighten the bolts in a cross pattern as shown
in Figure 15. Tighten the bolts to the value shown
in the Maintenance Schedule. When the bolts stay
tight after 8 hours, the interval for checking the
torque can be extended to 350 hours.
Inspect the drive tire and load wheels for damage.
Inspect the tread and remove any objects that will
cause damage. See Figure 11. Inspect the wheels
for loose or missing parts. Remove any wire, strap-
ping, or other material wound around the axles.

Mast, Forks, and Lift Chains
WARNING
When working on or near the mast or carriage,
see Safety Procedures When Working Near Mast.
DO NOT try to correct fork tip alignment by bend-
ing the forks or adding shims. Never repair dam-
aged forks by heating or welding. Forks are made
of special steel using special procedures. Replace
damaged forks.
Adjust the forks as far apart as possible for maxi-
mum support of the load. Hook forks are connected
to the carriage by hooks and lock pins. These lock
pins are installed through the top fork hooks and fit
into slots in the top carriage bar. Raise the lock pin
in each fork to slide the fork on the carriage bar.
See Figure 12.
