How to take good care of the semi trailer

1. Tire inspection of the semi trailer
(semi trailer)Check the tire pressure at normal temperature every month. If it is lower than the normal standard, supplement the tire pressure in time. The air pressure should not be too high or too low, otherwise the driving safety will be affected. Check the cracking of the tire. If there are potential safety hazards, replace the tire in time. When selecting tires, the models shall be consistent.

2. Battery maintenance and inspection of semi trailer
(semi trailer)Check whether the battery is firmly fixed, and the electrolyte shall be between the upper limit and the lower limit. When it is close to the offline, add electrolyte or distilled water to the high level line in time. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. For vehicles that have been stored for a long time, remove the positive and negative cables of the battery, rewire them every half a month or so, and charge them in time if the power is obviously insufficient after starting the engine for about 20 minutes.
