OPERATING INSTRUCTIONS
AIR SUSPENSION
Air Suspension Height/Air Pressure
Your vehicle may have an air suspension and a deflation switch which
allows the air in the suspension to be exhausted using a switch on the dash.
The normal purpose of this feature is to allow you to lower the vehicle for
loading. On prime movers, the deflate switch allows you to lower the fifth
wheel to slide under a trailer. A guard on the switch prevents you from
accidentally deflating the suspension.
Do not operate the Air Suspension Deflate Switch (Dump Valve) while
driving. Sudden deflation while your vehicle is moving can affect
handling and control and could lead to an accident. Use this switch
only when your vehicle is not moving.
Operating a vehicle with air suspension bags either overinflated or
underinflated may cause damage to driveline components. If a vehicle
must be operated under such conditions, do not exceed 8km/h.
Driving with Deflated Air Springs
If an air spring ruptures, there will be enough air pressure to drive the
vehicle to a safe stop off the highway to investigate the problem.
Do not drive with ruptured air springs. The air loss can cause the
spring brakes to apply. This allows your brakes to drag and may
burn up the linings, which could lead to an injury or accident. Do
not continue to operate the vehicle in this condition.
Do not tamper with the height adjustment valve on your Airglide rear
suspension. The height is factory-set for optimum performance. Consult
an authorised Kenworth dealer if the ride height requires adjustment.
Suspension Air Pressure Gauge
The Suspension Air Pressure gauge (optional) indicates the amount of air
pressure in the air suspension springs in kilopascals (kPa). Air pressure in
the spring is related to the rear axle load. The greater the rear axle load,
the greater the air pressure in the air bags. Therefore, the air pressure
displayed will vary, depending on the rear axle load.
