Excavator maintenance
1:
When changing the oil of the mini excavator, the oil filter element must be replaced at the same time. Because the dirt in the machine filter can destroy the quality of the new oil, thus reducing the life of the new oil.
2:
Change your winter oil in the fall and your summer oil in the spring, unless your oil is seasonal.
Since the oil in winter is slightly thinner, in summer, the oil in winter will become thinner, which is not conducive to the formation of oil film and will also increase the wear of mechanical parts.
In summer, after winter, the oil will become more viscous, which is not conducive to the flow of oil, which will lead to excessive carbon deposition in the engine cylinder, thereby increasing the wear of mechanical parts
3:
Compact crawler excavator must use standard oil. Use qualified oil products produced by regular manufacturers, and avoid greedy use of low-cost, low-quality, low-quality, and non-existent products. Select the appropriate grade of oil according to the excavator usage standards.

What small excavators need to pay attention to in daily life:
(1) Keep the amount of oil in the fuel tank normal, so that the system has sufficient oil circulation for cooling.
(2) Clean the cooling device to keep it in good working condition.
(3) According to the working environment temperature, select the appropriate hydraulic oil viscosity: if the ambient temperature is high, high-viscosity oil should be used, and if the ambient temperature is low, low-viscosity oil should be used. At normal ambient temperature, gear pumps should use 18 to 38 pf/s oil at 50°C.
(4) When the temperature is high, the continuous running time of the machine is too long. Generally, the continuous running time of the machine should not exceed 4 hours at temperatures above 30 degrees Celsius.
(5) When the temperature is lower than 10 degrees Celsius, the system should run without
