This article describes in detail the contents of the hydraulic excavator in the maintenance of the horizontal ground, the matters needing attention when the hydraulic excavator is engaged in the maintenance work at the high altitude, the attention content of the hydraulic excavator and the replacement of the filter, the content of the welding and maintenance of the hydraulic excavator.
Attention should be paid to the maintenance of hydraulic excavators on horizontal ground.
1 select the horizontal and hard safe ground repair.
The 2 shovel is placed on the horizontal ground.
3 turn off the generator and take the key.
4 a good crawler brake block.
Matters needing attention in the maintenance work of hydraulic excavators at high altitude:
1 straighten out the tools in the work area.
2 do not pour oil or grease, do not scatter the tools. Watch carefully when the locomotive goes.
3 when climbing or climbing down the engine, tools and handrails should be used, while surface skidding should be careful.
4 do not jump from high.
5 when working in collaboration, the signal to be used should be determined.
6 when working together, listen to the arrangement of the command.
Attention should be paid to oil drain and replacement of hydraulic excavators.
1 it is very dangerous to drain, drain or replace the filter when the generator has just stopped. It should wait for each component to be cooled (about 20-40 degrees centigrade) to do the work as above.
2 when the oil or filter is replaced, check whether there are metal fragments or other foreign objects in the oil and the old filter. If a large amount of metal debris is found, contact the manufacturer's service to repair it.
The content of welding and maintenance of hydraulic excavator:
1 cut off the power supply.
2 if you connect electrical components (microcomputers), please disassemble them.
3 clean up the voltage within the range of 1m in the welding area.
4 do not use the voltage above 200V continuously.
5 do not place any sealing part or bearing between the welding area and the ground.
6 before welding or home painting area, the paint should be removed first, and the area of heating paint will cause harmful gas.
7 when heated near the location of the hydraulic equipment and pipe, inflammable gas will be generated and start burning.
