Diesel Engine Exhaust Brake
The exhaust brake is available on vehicles equipped
with a diesel engine and air brakes (or an air
compressor). It is located in the exhaust system.
The exhaust brake is used when the vehicle is moving to
help slow the vehicle. The use of the exhaust brake will
assist the braking of the vehicle and prolong the life of
the foundation brake lining material.
When using the exhaust brake, the proper gear range
selection is important. The exhaust brake will be most
effective if the gear range selected is the lowest possible
range that does not allow the engine rpm to go more than
200 rpm above rated (full load) rpm as shown on the
Engine Information Plate. (Do not exceed 2900 rpm.)
The switch is located on the
lower right side of the
instrument panel and turns
the exhaust brake on and
off. The exhaust brake
indicator light is on when
the exhaust brake is in use.
The accelerator and clutch pedals must be released in
order for the exhaust brake to engage. Whenever the
EXHAUST BRAKE switch is in ON, the light in the
switch will be on.
Do not use the exhaust brake when running the engine
-
at idle during warm up or other extended periods.
Prolonged use of the exhaust brake during idling will
cause the engine to overheat.
CAUTION:
Be careful when using the exhaust brake or you
could lock the wheels and lose control of the
vehicle. Operators not familiar with an exhaust
brake should not use this brake on slippery
surfaces before learning to use it on dry surfaces.
If the vehicle's wheels begin to lock when using
the exhaust brake on slippery surfaces, switch the
exhaust brake off immediately. The exhaust
brake will turn off if the anti
is activated.
