WHEEL BRAKE LOCK CONTROL
The Wheel Brake Lock (12, Figure 5-5)
should be used with engine running for
dumping and loading operations only. The
brake lock switch actuates the hydraulic brake system
which locks the rear wheel service brakes only.
When pulling into shovel or dump area, stop the truck
using the foot-operated service brake pedal. When
truck is completely stopped and in loading position,
apply the brake lock by pressing the rocker switch
toward the “On” symbol. To release, press the rocker
switch toward the “Off”symbol.
Use at shovel and dump only to hold truck truck in
position.
Do not use this switch to stop truck, unless foot-
operated treadle valve is inoperative. Use of this
switch applies rear service brakes at full, unmodu-
lated pressure!
Do not use brake lock for parking. With engine
stopped, hydraulic pressure will bleed down, al-
lowing brakes to release!
PARKING BRAKE CONTROL
The Parking Brake (13, Figure 5-5) is spring
applied and hydraulically released. It is de-
signed to hold a stationary truck when the
engine is shutdown and keyswitch is turned “Off”. The
truck must be completely stopped before applying the
parking brake, or damage may occur to parking brake.
To apply the parking brake, press the rocker switch
toward the “On” symbol. To release the parking brake,
press the rocker switch toward the “Off”symbol. When
the keyswitch is “On” and Parking Brake switch is
applied, the Parking Brake indicator light (A3, Over-
head Panel, Figure 5-6) will be illuminated.
NOTE: Do not use the parking brake at shovel or
dump. With keyswitch “on” and engine running, sud-
den shock caused by loading or dumping could cause
the system’s motion sensor to RELEASE the park
brake.
