60 INSTRUMENTS AND CONTROLS
•
Accessory Switch (Ignition Power)
– This switch may be used to power optional
accessory equipment that requires ignition voltage, with the key switch turned ON.
•
Air Suspension Control Switch
– This switch exhausts the air from the air bags
of the suspension. It may be used when coupling or uncoupling trailers.
CAUTION
When preparing to connect a tractor to a trailer, make sure that the height of the 5th wheel
matches the height of the underside of the trailer. Failure to do so will result in the trailer
being improperly connected. After the trailer has been coupled and the trailer landing
gear has been raised, make sure that the 5th wheel jaws have properly engaged the trailer
king pin, and there is no gap between the 5th wheel plate and the bottom of the trailer.
CAUTION
DUMP BODY: Always exhaust the air from the bags before raising the dump body to
protect the air bags and improve chassis stability while dumping. If the dump body is
raised while the air suspension is pressurized, damage to the air bags may result.
CAUTION
Do not drive the vehicle with the air bags exhausted. Repressurize the air bags before
driving the vehicle.
Note:
Engine speed and road speed will automatically be limited if the vehicle is moved
with the air bags exhausted.
