Hydraulic oil will expand in hot weather and be discharged from the exhaust hole.

What you want to ask is what should I do if the hydraulic oil expands from the vent in hot weather? Method:

1. Run the system to make the oil flow. When the temperature rises, open the vent hole on the oil tank, and the air in the oil can be discharged slowly.

2. Open the exhaust device of the hydraulic cylinder to make the hydraulic cylinder move slowly. At the same time, observe whether there is air discharged from the exhaust device until there is no air. Install the exhaust plug and repeat 1 time to 3 times.
