Running gear
(1) Check tires
The outer surface of the tire should be undamaged, with no foreign objects stuck or embedded, and the air pressure should be normal. Inflate it if necessary. If the bolts are loose, they should be tightened. If the tread wear is serious, check it out.
reasons and deal with them.
(2) Check the left and right wheel hubs of the front axle
If there is oil leakage, it should be dealt with.
Braking System
(1) Eliminate water and sediment in the air reservoir
Open the waterproof valve and remove the accumulated water and sediment in the air reservoir.
(2) Check the oil-water separator
Drain oil and water once every 25 working hours.
(3) Check pipelines and pipe joints
Eliminate air leakage and tighten pipes and pipe joints if they are loose.
(4) Check the brake air pressure.
The brake air pressure should be 656.6 ~ 682.488kPa. If necessary, adjust it through the air pressure regulator.
(5) Check the safety valve (on the air reservoir)
Check every 50 working hours. When the air pressure rises to 980 ~ 1078kPa, the safety valve should be able to open automatically.
(6) Check the driving braking performance
Braking should be smooth, sensitive and reliable.
