1. Evaluate the use of hydraulic oil
After the hydraulic oil is used (observe its quality, it can be assessed by appearance and odor or the oil supplier can make an accurate assessment) or it needs to be replaced after being contaminated by water.
High-pressure water in the supercharger may enter the oil. Severe leaks can cause water to seal into the oil through the piston rod. If the surface of the oil is milky, it means that the oil contains water. This will damage the oil pump. At this time, it is required to immediately stop the pump, drain all the oil, clean the parts, replace the oil, replace the seal of the end cap and seal the piston rod.
When the oil pump is working at an excessive oil temperature, the service life of the oil will be reduced. The recommended oil temperature is below 50°C but not below 10°C. When the temperature exceeds 55°C, the machine should be shut down until the oil temperature cools down.
The new oil is almost clean and tasteless. After high temperature operation, the color of the oil darkens and the odor deteriorates. When the oil becomes darker and thickens with an unpleasant odor, it indicates that the oil needs to be changed. When changing the oil, the oil filter must also be replaced..
2. of hydraulic oil
Hydraulic oil should be injected into the tank through the fill port.
