OPERATING INSTRUCTIONS
Compression Brake System
The amount of braking power available
in a given engine series varies. Braking
power depends on turbocharger boost
pressure, engine speed, compression
ratio, injector timing, and when the
engine brakes open the exhaust
valves.
Engine brake controls, with the fuel
system, consists of the following:
•
A two-position selector switch
standard (three-position selector
optional).
•
An ON/OFF switch.
•
A clutch switch.
•
A throttle sensor.
With the ON/OFF switch in the “ON”
position, the brake automatically
creates its braking effect when you
remove your foot from the accelerator
pedal.
