1. Operators must be familiar with the contents of the instruction manual and operate it.
2. Special precautions in winter:
A) When starting the oil pump in winter, the hydraulic oil should be heated as needed, and it can only be put into use when the oil temperature rises to more than 15°C. Low freezing point hydraulic fluid is used in alpine areas.
B) In winter, the hydraulic oil gear oil should be replaced with anti-freeze as needed, and the pipeline can be added with a heating belt if it is afraid of freezing cracks.
