Some common faults often occur in the construction of excavators, such as the deviation of the excavator, which may be caused by the damage of the oil seal of the traveling distribution, also known as the oil seal of the central swivel. The two hydraulic pumps have different flow rates. There is a problem with the traveling motor. The hydraulic cylinder is quickly discharged, the safety overflow valve is not tightly closed, or the cylinder oil seal is seriously damaged, etc. Daily maintenance of excavator in order to prevent the failure of excavator, great attention should be paid to the maintenance of excavator in the process of daily use.
Routine maintenance includes checking, cleaning or replacing the air filter element. Clean the inside of the cooling system. Check and tighten the track shoe bolts. Check and adjust the reverse tension of the track. Check the air inlet heater. Replace the bucket teeth. Adjust the bucket clearance. Check the front window washer fluid level. Check and adjust the air conditioner. Clean the floor in the cab. Replace the crusher filter element.
When cleaning the inside of the cooling system, after the engine is fully cooled, slowly loosen the water injection port cover and release the internal pressure of the water tank before discharging water. Do not carry out cleaning work when the engine is working. The fan rotating at high speed will cause danger. When cleaning or changing the coolant, park the machine on a level ground.
At the same time, before starting the engine, check the liquid level of coolant and add water if necessary. Check the engine oil level and add oil if necessary. Check the fuel level and add fuel if necessary. Check the hydraulic oil level and add hydraulic oil if necessary. Check whether the air filter element is blocked. Check the wires. Check whether the horn is normal. Check the lubrication of the bucket. Check the water and sediment in the oil-water separator.
