Routine inspection work is an important part of ensuring that hydraulic excavators can maintain efficient operation for a long time. Especially for self-employed individuals, doing a good job in daily inspection work can effectively reduce maintenance costs.
First, turn around the machine twice to check the appearance and whether there is any abnormality in the mechanical chassis, and whether there is grease flowing out of the slewing bearing, then check the deceleration brake device and the bolt fasteners of the crawler. If it is a wheeled excavator, it is necessary to check whether the tires are abnormal and the stability of the air pressure.
Check whether the bucket teeth of the excavator have great wear. It is understood that the wear of the bucket teeth will greatly increase the resistance during the construction process, which will seriously affect the work efficiency and increase the wear degree of equipment parts.
Check the stick and cylinder for cracks or oil leakage. Check battery electrolyte to avoid below low level.
The air filter is an important part to prevent a large amount of dusty air from entering the excavator, and it should be checked and cleaned frequently.
Always check whether fuel, lubricating oil, hydraulic oil, coolant, etc. need to be added, and it is best to select the oil according to the requirements of the manual and keep it clean.
Check after start
1. Sound the horn and all gauges are in good condition.
2. Engine starting state, noise and exhaust color.
3. Check for oil, fuel and coolant leaks.
