1. Daily maintenance:

(1) After each operation, the trailer body and chassis should be cleaned in time.

(2) Check whether all safety devices and light pens are reliable.

(3) Check whether the leaf springs and U-bolts on the front and rear axles of the trailer are loose, displaced, cracked or broken.

(4) Check the tire inflation. Inflate tires as specified. The error shall not exceed 0.5kg/cm2±. Check the tightness of the nuts on each wheel.

2. Perform the following maintenance on the trailer every 600~800km:

(1) Check the leaf springs, bushings and pins. If the leaf spring pin is worn more than 1.5mm, the gap between the pin and the bushing will be too large and should be replaced.

(2) Lubricate all parts as required, check the hub bearing clearance, adjust if necessary, and add calcium-based grease.

(3) Check whether there are cracks in the welding joint of the frame, whether the connecting bolts are loose, and check the tightness of the braking system and the vehicle's main brake control mechanism.

3. When the trailer travels 3000~4000km, in addition to the above maintenance, the following maintenance should also be performed: 

(1) Clean and adjust the wheel hub bearings, add grease; clean and check the wear of the spring steel plate, repair or replace if necessary; adjust the bearings clearance, please screw the adjusting nut to the bottom first, then return it 1/6 turn, and then lock it.

(2) Check and adjust the brake, and repair or replace the brake drum according to the wear condition. The brakes cannot be adjusted too tight. When the unit is running at a speed of 18km/h, it is appropriate for the wheel braking mark to reach 4~5m.

(3) Check the traction frame, frame, wheel axle and other parts to see if there are bends, deformations, cracks, and repair if necessary.
