As excavator drivers, in order to make their excavators less likely to fail, we should pay attention to the maintenance of the excavator in ordinary use.
Agricultural crawler mini excavator
- Engine.
Oil, oil filter absolutely must be used genuine factory parts, according to the specified maintenance cycle replacement. Older machines need more careful care, oil filter replacement time can be shortened as appropriate, in order to make the engine life longer.
Diesel fuel as far as possible to use the regular gas station to provide, even if the regular gas station to add diesel fuel, do not directly into the tank, join before filtering (more commonly used method is in the refueling mouth socks). Put water at the bottom of the diesel tank and oil-water separator before starting work every day. Diesel filter buy genuine parts, according to the specified maintenance cycle to replace the diesel filter. (To clarify, the genuine plant filter paper is fine, the impurity interception amount is large, so it is easier to block, than the secondary plant filter replacement cycle is shorter, so not a long-term non-clogging filter is a good filter)
The air filter element should be checked frequently, and the outer filter element should be blown from inside to outside with compressed air, and the air pressure should not be too high to prevent the filter element from being blown out. The inner filter should not be cleaned. After cleaning the outer filter 2 or 3 times, replace it with a new one at the same time as the inner filter.
Do not use the idle speed for a long time in order to save fuel and prevent the accumulation of carbon.
- Hydraulic.
Replace the hydraulic oil, return oil filter element and pilot element according to the prescribed maintenance cycle, and pay attention to whether the filter element has adsorbed iron chips and copper chips.
When using the crusher, the hydraulic oil deterioration and deterioration accelerated, the replacement cycle should be shortened.
Do not work without oil for a long time.
After replacing the hydraulic oil or hydraulic parts, pay attention to expel the air.
- Electrical.
Pay attention to waterproof, do not wade into deep water operation, do not use water to flush electrical parts directly when doing cleaning.
Do not pile up debris in the battery box, especially metal tools, etc., easy to start a fire.
Do not use wire and copper wire instead of insurance, and do not replace the insurance with non-standard.
Excavator long-term parking to dismantle the battery line to prevent power feed.
- Machinery.
Rotation reducer, walking reducer replace gear oil according to cycle.
The pin part pay attention to clean up the mud and debris, filling grease.
Water operation, water over the rotary gear ring, pay attention to the replacement of the rotary gear ring grease.
Pay attention to the cylinder rod to prevent rust.
When the excavator is parked for a long time, apply grease to the exposed metal part to prevent rust.
- Structure.
Check daily whether the pin bolt is loose, off or missing, and tighten it in time.
Check the structure every day for cracks and deformation.
Pay attention to the surrounding environment when parking the excavator, park it on solid and stable hard ground, not on the river, cliff side, under the slope to prevent accidental danger.
When parked, the bucket cylinder is completely retracted and the bucket falls to the ground to prevent the cylinder from being hit.
