OPERATION
OPERATING INSTRUCTIONS
The digital display will indicate “2X” (“X” is the
current gear and “2” is the gear it is aiming for)
while this happens. When second gear is attained
and machine has slowed, the exhaust brake will be
disengaged and the digital display will return to the
previous value shown.
When the machine has slowed down, the engine
brake will be disengaged.
Exhaust Brake Protection
If this message displays, report to Technical Personnel
immediately.
If the CCU detects an exhaust brake failure, an
exhaust brake protection pop-up message will be
displayed on the CDU every 5 seconds.
Brake Retarder
For increased safety, the service brakes are used to
assist the park brake.
If the park brake is applied then 100% brake
retardation is requested independent of the
operator-selected retardation value.
The brake retarder, as well as the engine retarder is
automatically engaged when the accelerator pedal
is released.
The retarder light on the CDU will light whenever
the service bakes and engine brake are activated.
The brake retarder is applied when a retarder
position is selected at the retarder switch and the
accelerator pedal is fully released.
Retardation can be selected from a choice of 6
different retardation percentages.
To resume driving, release service brake pedal.
The transmission will automatically select the
lowest gear.
Service Brakes And Park Brake
During normal operation the machine must be
stopped using the service brakes. When the
machine is stopped and the transmission is set to
Neutral with no service brake signal, the park brake
will be automatically applied immediately.
Service Brakes
The brakes may not function 100% when the hydraulic oil
has not reached working temperature. Stopping distan-
ces will increase until working temperature has been
reached.
Avoid using the service brake over extended periods.
Excessive use of the service brakes will result in the
brake assembly overheating which in extreme circum-
stances could result in a brake assembly failure.
Stopping the machine with the service brakes is
done as follows:
1. Release the accelerator.
When the accelerator is released the engine re-
tarder and brake retarder will be activated.
It is recommended that the retarder brake func-
tion is used to slow the machine down and the
service brakes used to stop the machine.
2. While driving the machine normally the brake
pedal must be pressed.
The transmission will automatically select the low-
est pull-off gear.
Park Brake (Normal Operation)
The park brake will be automatically applied, imme-
diately, when the machine is stopped and the trans-
mission placed in neutral, with no movement on the
service brake pedal.
The park brake must only be applied when the ma-
chine is completely stationary.
When the machine is to be stopped for more than a
few seconds the following must be done:
• Stop the machine using the service brake.
• Apply the park brake.
• Select Neutral N.
• Release the service brake.
Park Brake Protection
The park brake protection feature is to assist in
pulling-off on an incline.
When the service brake pedal is not pressed and
the truck is standing still (less than 1km/h) with the
