Moving a Disabled Lift Truck
In order to move a disabled lift truck, the electric
brake must be released by powering the brake coil
with battery voltage. A jumper is provided in the wiring
harness to supply battery voltage directly to the elec-
tric brake to release it. The truck will roll freely, but the
drive motor will not activate while the jumper is instal-
led.
WARNING
Prior to releasing the electric brake, make sure
the lift truck is blocked correctly to prevent move-
ment, causing personal injury or damage to
equipment.
1. Turn the key switch to the OFF position.
2. Disconnect and separate the battery connectors.
3. Remove the upper drive unit compartment cover.
4. Remove the lower drive unit compartment cover.
5. On the main wiring harness approximately
300 mm (12 in.) above the MDU, the brake wiring
harness is connected. An extra four-pin connector
for the brake override feature is secured near this
connection with wire ties.
6. Disconnect the connectors and connect the brake
wiring harness to the brake override connector.
See Figure 5.
NOTE: The brake will release when battery is con-
nected. The brake will remain released until the bat-
tery is disconnected or the brake override circuit is
disconnected.
7. Connect the battery connectors.
8. Roll the lift truck to a safe, level area prior to per-
forming any repairs on it.
CAUTION
Always unplug the Brake Override Circuit and
connect the Brake Harness prior to operating the
lift truck.
9. Make sure the brake override circuit is disconnec-
ted from the brake harness. The brake will remain
released until the battery or the brake override cir-
cuit is disconnected. Restore the harness connec-
tor to the normal operation connector correctly be-
fore attempting to operate the lift truck.
