brake is damaged, the hand brake can be used in
place of the service brake to drag the vehicle.
3. Auxiliary brake
Auxiliary brake is the engine exhaust brake.
When the vehicle travels down a long slope in
the mountains, in order to prolong the service
life of the brake, the exhaust brake switch can be
operated to realize the engine exhaust brake by
closing the butterfly valve on the exhaust pipe
through an electromagnetic valve control cylinder.
4. Precautions for braking
operation
When self-braking is caused by the pipe
connecting the spring brake chamber due to
leakage, the release process of the brake is as
follows (see Figure 7-10a): a. Open blanking
cap at the end of the brake chamber; b. Unscrew
the nut on the screw, and remove the screw; c.
(see Figure 7-10b)Put the screw in from the end
of the brake chamber and lock it; d.Tighten the
nut so that the screw rotates out, then the brake
can be released. When parking on a sloping
road, the wheels must be plugged with wedge
to prevent slide of the vehicle before lifting the
spring brake.

7-4-1 Cooling system

In order to ensure the normal use of the
vehicle in the winter, we recommend the use of
long-lasting antifreeze, and the antifreeze model
should be selected based on the local ambient
temperature. See antifreeze in section 11.6.

●Seawater is strictly prohibited to directly fill in
the cooling system.
●Replacement of the antifreeze should be
carried out in accordance with use requirements
of the engine. The freezing point of antifreeze
should be 5℃ lower than the minimum low
temperature.
