Lifting the Vehicle
Lifting the front: To remove a front wheel or axle:
First chock the front and rear of the rear tires. Loos-
en the front wheel hardware. Position the jack in the
location indicated in Figure 13 below and carefully
raise the front of the vehicle, taking care that the rear
wheels do not move. Position jack stands in the lo-
cations indicated and slowly lower the vehicle to rest
on the jack stands and test the stability of the vehicle.
Lifting the rear: To remove a rear wheel or axle, first
raise the front of the vehicle as previously described
and support on jack stands. Then position the jack
in the position indicated at the rear of the vehicle.
Carefully raise the rear of the vehicle with the jack
and place two jack stands in the positions indicated.
Slowly lower the vehicle to rest on the jack stands
and test the stability of the vehicle. Lower the vehicle
by reversing the lifting sequence.
The vehicle may be lifted with an overhead crane
and J-Hooks. The J-hooks should be attached to the
frame at the four corners of the battery/engine com-
partment. The crane capacity should be greater than
1200 lbs (standard battery) or 1500 lbs (industrial bat-
tery). Do not work under the machine when hoisted
by a crane.
Figure 13: Position the jacks or jack stands
Do not lift the vehicle on unlevel or unstable sur-
faces. When lifting the vehicle to jack stands, al-
ways lift and secure the front of the vehicle first. If
the rear of the vehicle is lifted first, the front may
become unstable.
• Soft Solid
• Solid Non-Marking (off-white)
Although all of these should be inspected periodi-
cally, only the pneumatic tires require maintenance.
Make certain that the tire pressure is maintained at 60
psi for LRB tires and 90 psi for LRC tires.
Changing the vehicle’s tires is very much like chang-
ing an automobile tire. Follow the procedure below
to change the tire safely.
1. Position the jack in the proper position (Figure
13)
2. Loosen the lug nuts on the wheel to be changed.
3. Raise the jack until the tire is clear of the sur-
face.
4. Remove the tire.
To replace the tire, reverse the procedure, tighten-
ing the lug nuts to 70 to 80 ft. lbs. (95 to 108 Nm)
torque.
Brakes
The vehicle is equipped with a pair of rear mechan-
ical drum brakes which only engage for parking and/
or emergency stopping. Normal braking uses the
regenerative braking controlled by the combination
accelerator/brake pedal.
Mechanical brakes are adjusted by advancing the
two nuts on the central rod until the slop disappears.
Brake wear may cause the need for a repeat adjust-
ment..
