Correct operation
Retarder operating switch
The retarder operating switch is located on the
right handle of the combined switch.
Operate the retarder with two gears and close the
handle in the middle position of the retarder.
Push one gear ahead of the handle to keep the
speed of the retarder constant.
Push forward the handle continuously, which is
the second gear of the retarder and the maximum
deceleration gear. When the maximum brake stop is
used, the brake lamp is on to remind the rear vehicle
to pay attention.
The retarder braking is to convert the kinetic
energy of the vehicle into thermal energy, which is
carried away by the engine circulating coolant.
When the cooling water temperature of the engine
and the oil temperature of the retarder exceed the
set value, the retarder prompts the driver in the form
of an alarm and slowly withdraws from the braking.
Caution
⊙
The acceleration pedal must be released before
the retarder is activated.
⊙
If the ambient temperature is low and the
retarder is used for the first time after starting, the
braking effect will lag behind.
⊙
In order to better apply and play the role of
hydraulic retarder, the downhill speed and engine
speed can be reasonably selected in actual
applications according to the factors of vehicle
weight, slope and slope length so that the retarder
does not alarm or quit work. Specifically, if the
vehicle is heavy, long and steep, the gearbox needs
to be shifted into a low gear so that the engine speed
can be maintained at more than 1500 rpm so as to
increase the heat discharged from the cooling
system and maximize the braking force of the
retarder.
⊙
For the type of vehicle matching retarder, the
expansion box may appear exhaust phenomenon in
the retarder operation. If it is found that the height
of coolant drops, it is necessary to add coolant.
⊙
In order to give full play to the efficiency of
retarder and improve its service life, antifreeze is
used as engine cooling medium.
Warning
⊙
The retarder handle is in any working gear, and
the gearbox must ensure proper forward gear (no
retarder is allowed to be used in idle sliding) so that
the engine cooling system can take away the heat
generated by braking.
⊙
The retarder should be used in a timely and safe
road condition. It is forbidden to use the retarder
when the road surface is wet and slippery, such as
snow, ice, sand and a lot of water.
⊙
When the vehicle is idle, the retarder should be
reasonably used, and the brake handle of the
retarder should be pulled down step by step to
prevent excessive braking from affecting driving
safety.
⊙
It is forbidden to use retarders when a tractor is
driving in sharp bends.
⊙
The retarder cannot be used as parking brake.
⊙
If the vehicle cannot "constant speed" and
become faster, it must use the driving brake.
