1. Use starting fluid for excavators
Baking oil tank, baking oil pan3
In winter, cover the engine with a quilt or blanket to rece heat loss and speed up the hot car now has many fuel heating systems. The basic principle is to heat up the low-pressure oil circuit of the fuel tank, oil pipe and filter to remove the phenomenon of icing and wax deposition of diesel oil, ensure the normal fuel supply of the engine, optimize the quality of fuel spray, make the engine burn more fully and have a good protective effect on the engine. So as to prevent the excavator from starting in winter
5. When the ambient temperature decreases, the battery power loss also decreases. If the charging ratio of the battery is low, the battery electrolyte will freeze. Keep the battery charge close to 100% and insulate the battery from low temperature so that the machine can be started easily the next morning
since the capacity of the battery will decrease obviously at low temperature, it is necessary to pack the battery, unload it from the machine, put it in a warm place, and install it on the machine the next morning. If there is oxide on the column, it can be washed with boiling water, which can increase the battery life
excavator maintenance precautions:
daily inspection is an important link to ensure that the hydraulic excavator can maintain efficient operation for a long time, especially for the self-employed, daily inspection can effectively rece the maintenance cost
first, rotate the machine twice to check whether the appearance and the mechanical chassis are abnormal, and whether there is grease flowing out of the slewing bearing, then check the deceleration braking device and the bolt fasteners of the crawler, the tightening and replacement should be timely replaced, 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 excavators have large wear. It is understood that the wear of bucket teeth will greatly increase the resistance in 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 the battery electrolyte to avoid being below the low level line
the air filter element is an important part to prevent a large amount of sty air from entering the excavator, and it should be checked and cleaned frequently. Often check the fuel, lubricating oil, hydraulic oil, coolant, etc., whether it needs to be added, and it is best to select the oil according to the requirements of the manual, and keep it clean
