Maintenance matters for semi-trailer

Release time:2024-10-22Page View:8

Firstly, tire inspection

The tire pressure should be checked at room temperature every month, and if it is lower than the normal standard, the tire pressure should be replenished in a timely manner. The air pressure should not be too high or too low, otherwise it will affect the safety of driving. Check the cracking of the tires and replace them promptly if there are safety hazards. When selecting tires, the model should be consistent.

Secondly, maintenance and inspection of the battery

Check whether the battery is firmly fixed, and the electrolyte should be between the upper and lower limits. When approaching the lower limit, the electrolyte or distilled water should be added in a timely manner to the high line. Keep the positive and negative cables of the battery in good contact and keep the battery clean and dry. Vehicles that have been stored for a long time should remove the positive and negative cables of the battery, reconnect them after about half a month, and start the engine for about 20 minutes. If the battery is significantly low, it should be charged in a timely manner.

Thirdly, check the fluid level of the clutch master cylinder

If the clutch fluid level is between high and low, it indicates normal. If it is below the standard line, it may be due to damage to the master cylinder or sub cylinder cup. When the engine is running, there may be difficulty or inability to shift gears. Please go to the nearest maintenance station for inspection immediately.

Fourth, check the brake fluid level

Braking between high and low positions indicates normal operation. If the brake fluid is close to or below the lower limit, it indicates that there may be a leak in the system or excessive wear of the brake shoes, and it is necessary to promptly go to the repair station for maintenance. When adding brake fluid, pay attention to adding the same type of brake fluid to prevent damage to the leather cup, and protect the paint to prevent corrosion of the paint surface.

Fifth, check the engine coolant level

When the engine is in a hot state, do not open the radiator cap, otherwise it may be burned by splashing coolant or high-temperature steam. After the engine cools down, check that the coolant level is between full and low. Otherwise, distilled water, purified water, or coolant should be added. The height of the coolant level after adding water should not exceed full. If it is found that the coolant decreases rapidly in a short period of time, the cooling system should be checked for leaks or taken to a repair station for inspection.
