Operation

Using Air Brakes

WARNING

To prevent personal injury and / or death, or
damage to property, always check and maintain
brakes in proper condition and adjustment.
Out-of-adjustment brakes could cause reduced
braking ability.

Do not apply and release (pump) the brakes rapidly. This is an
inefficient way of slowing or stopping a vehicle and inefficient use
of air pressure. This also reduces the ability of the ABS system
to function properly.

Using the Air Parking Brake

WARNING

To prevent personal injury and / or death, or
damage to property, before starting the engine,
the parking brake control knob must be in the
applied (pulled) position. Failure to do so could
allow the vehicle to roll.

The purpose of the parking brake is to hold the vehicle in the
parked position. It should NOT be used to brake the vehicle
during normal driving. It may be used to assist in making an
emergency stop in the event of service brake failure.

Parking Brake / Wheelchair Lift (Optional) Interlock.

On

vehicles equipped with an optional wheelchair lift, power will not
be supplied to the wheelchair lift mechanism unless the parking
brake is applied.

NOTE: On vehicles equipped with optional wheelchair lift,
the parking brake cannot be released until the wheelchair
lift is completely stowed.

NOTE: For a complete description of these interlocks, see
the Parking Brake / Wheelchair Lift (if equipped) Interlock
procedures in the Hydraulic Brake section.

To Engage Air Parking Brake

1.

Bring the vehicle to a complete stop, using your brake
pedal.

2.

Ensure the engine is at low idle.

3.

With your foot still firmly on brake pedal, place
transmission in neutral position.

4.

Pull the parking brake control knob to apply the parking
brake.

To Release Air Parking Brake

1.

Have the engine running and your foot on the service
brake pedal.

2.

Push in the control knob.

3.

Wait until system pressure has reached 70 psi.

NOTE: DO NOT operate vehicle until system pressure has
reached 70 psi.

NOTE: To release the parking brake on vehicles with the
optional wheelchair lift, the lift must be completely retracted
and stowed.
