MOTOR
Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
GENERAL
Do not hold vehicle on hill by using accelerator and
motor. Leaving the motor in a stalled condition for more
than 3-4 seconds will raise the commutator bars resulting
in unacceptable noise and accelerated brush wear and
cause permanent damage to motor.
Disassembly of the motor is not recommended except to
replace a worn or noisy bearing. If the motor is disas-
sembled, it should be cleaned of any dirt buildup and the
brush length checked. Replace brushes if required.
The motor housing is not available as a service item,
therefore in the unlikely event of a failure in this compo-
nent, the entire motor must be replaced.
Motor Removal
Disconnect the negative (BL-) battery cable
with an insulated wrench before attempting to
remove wires from the motor (see safety pro-
cedures in SAFETY section of this manual).
The shorting of motor wires could cause an
explosion.
