OPERATION 119
Parking Brake Operation
The parking brakes can be applied and released from the cab, using the hand-operated
push/pull control valve with the yellow diamond knob.
In the event of a significant air pressure loss in both the air brake systems, the spring brake
air chambers will be automatically exhausted (applying the brakes). The parking brakes will
remain applied until enough pressure is available to recompress the springs.
Parking
WARNING
• NEVER use the trailer parking brake
system alone.
• NEVER use the tractor parking brake
system alone.
• ALWAYS use the tractor and trailer
parking brake systems together.
• ALWAYS apply the parking brakes when
parking and make sure the parking brakes
are holding the vehicle from moving before
leaving the driver’s seat.
• When parking on a grade, use wheel
chocks under the rear wheels or turn the
front wheels to the curb. Do not leave
diesel engine vehicles in gear; if the vehicle
should move, the engine may start by heat
of compression.
• Check brake adjustment frequently to be
sure that the brakes will lock and hold the
vehicle when parked.
• Do not use the parking brake to slow or
stop the vehicle when in motion, except in
an emergency.
• Do not use hand control valve for parking.
