function of engine exhaust brake. After you press the exhaust
brake switch, the running vehicle can utilize the energy from
engine for auxiliary brake.
When driving down a long slope, be sure to use the
exhaust brake. In case of running on icy or muddy road, the
use of exhaust brake can reduce the risk of side slide. In the
event of meeting other vehicles or passing through poor road,
it is better to use the exhaust brake to accelerate. The use of
auxiliary brake can reduce the times of applying main brake,
which will reduce the wear and heat of wheels and final
drive so as to extend their service life, reduce fuel
consumption and increase driving safety. After driving down
a long slope, simply check the performance of the exhaust
brake.

! CAUTION: When transmission is in neutral and
the clutch is released, the auxiliary brake will not work.
When the speed of engine is lower than 1,100 r/min, the
auxiliary brake will not work. The exhaust braking efficiency
is higher at low gears.
4.8.3 Emergency and parking brake
The hand brake can be used for emergency braking
and parking brake. It works via the energy storage
spring brake chamber of axle. Parking brake can be
realized by operating the hand brake valve handle.
When brake system is in failure, relying on the push
of energy storage spring, the emergency braking can
be realized automatically. Only when the pressure in
