Drive Motor Brake Removal and Adjustment
A brake assembly is mounted to the front of each drive
motor housing. The brakes are ENGAGED (brakes on) when
the machine is parked and are RELEASED electrically
(brakes off) when the joystick is enabled and pushed in any
direction. The brakes can also be RELEASED electrically
using the manual brake release button on the ground con-
trol station.
NOTE: The brakes are intended only as parking brakes to
keep the machine from moving while at rest. The
brakes are not used to stop the machine during driv-
ing operations, this braking is controlled by the drive
motors themselves. Under normal driving conditions,
once released the brakes are not engaged again
until the machine comes to a complete stop.
