How to warm up the excavator in winter?
It is very difficult to get up early in the cold winter, so is your favorite machine, you must be "warm" to get up early and start working!
The normal temperature of the hydraulic oil of the machine is about 50°C. When the oil temperature is lower than 25°C, if it is operated violently, the hydraulic equipment may have a major failure. Therefore, the working oil should be heated to above 25°C before operation.
If the working device is started directly without sufficient warm-up, the response of the working device to the operating lever is slow, and sometimes abnormal howling sounds may occur. Therefore, in severe cold weather, please perform sufficient warm-up before starting work.
