SM 2124 Rev 3 8-03
Note: In cold weather, the transmission oil should be
warmed up by running the engine at idle speed with
the gear selector in neutral, since the system will not
operate satisfactorily if the oil is too cold.
When temporarily stopped, such as for yielding the
right-of-way to a loaded machine, the transmission
can be left in gear and the machine held stationary
with the service brakes.
When stopped for a more extended period with the
engine left running, shift to 'NEUTRAL' to avoid
unnecessary heat buildup, and apply the parking
brake.
WARNINGS
Always select the correct drive direction and
gear before releasing the parking brake.
Never allow the machine to coast with the
transmission in 'NEUTRAL'.
WARNINGS
When running down a gradient the engine
speed should not be allowed to drop below
1 200 rev/min, at which point, lockup would
disengage preventing retarder operation.
In the event of a loss of electric power to the
gear shift control, the transmission will
automatically shift to 'NEUTRAL'. If this
occurs, stop the machine using the service
brakes and apply the parking brake. Do not
operate until the fault has been repaired.
Always select 'NEUTRAL' and apply the
parking brake before leaving the operators
seat.
The retarder will automatically disengage when
the oil temperature reaches 150° C (302° F),
irrespective of engine speed.
