12. When mounting the air filter, make sure to mount the filter element and end cover
properly; otherwise dirt may be absorbed, sharply shortening the engine service
life. Never clean the filter element with gasoline or water. Check the sealing rings
during installation. Tighten the filter element and end cap nut, and install the
sealing ring of the end cap properly. Do not remove the air filter when the vehicle is
running.
13. Do not tighten the fuel primary filter or the fuel filter with fuel primary filter by a filter
spanner during installation. Otherwise the threads may deform and the filter may
be damaged. When mounting a new filter, note whether its model conforms to that
required by this engine. Before the oil filter is installed, it should be filled with oil.
14. Bleeding is prohibited when the engine temperature is high. The starting time of
the engine must not exceed 30 s, and the interval between starting operations
shall be 2 min at least.
15. For the manual adjuster, check the brake clearance regularly and adjust it in time if
the braking is weak. During the adjustment of brake clearance, never change the
push rod travel by screwing the connecting yoke of the brake air chamber push
rod. To adjust the rear brake, always park the truck on flat place and ensure the air
reservoir pressure is above 700 kPa. Then chock the wheels at the front and back,
and after releasing the parking brake, adjust the rear brake clearance.
16. For the automatic regulating arm, manual adjustment of brake clearance is
prohibited except for special circumstances; Check the wear situation of friction
disc regularly to prevent braking failure caused by excessive wear of friction disc.
When adjusting the brake clearance manually, it is strictly forbidden to change the
stroke of the push rod by turning the brake air chamber push rod to connect the
fork. When manually adjusting the rear brake, make sure the vehicle is parked on
a flat place and ensure the air pressure of the storage cylinder is above 700kPa.
The front and back of the wheel are choked with a triangular pad, and the brake
clearance can be adjusted after the parking brake is lifted. In case of abnormal
braking conditions, stop immediately to check the working conditions of the
automatic regulating arm and other parts of the braking system, and take
appropriate measures to eliminate the fault.
17. Disc brake can automatically adjust the brake clearance, except for special
circumstances, manual adjustment of the brake clearance is prohibited. If the
brake clearance is found to be abnormal, check the clearance adjustment
mechanism function.
18. Auxiliary braking (exhaust braking, engine braking, retarder) is strictly prohibited
on wet slippery road surface.
19. For vehicles with ESC (electronic stability control system of vehicle body), ESC
self-learning calibration must be carried out at the service station when the
steering wheel, steering tie rod, front axle and steering wheel string are replaced.
During vehicle restructuring, the position of ESC module shall not be moved or the
installation direction of ESC module shall not be changed.
