What Should Be Paid Attention To Before Maintenance Of Hydraulic Press?

1. Wipe off the oil marks and water marks on the ground to prevent slipping.
2. Make sure that the compressor unit has been cooled to prevent scalds and burns.
3. Cut off the power supply of the host computer and hang a sign on the power switch.
4. Open the manual vent valve to vent the pressure in the system and keep the vent valve open.
5. For water-cooled machines, the water supply system must be closed to release the pressure of the water pipeline.
6. Close the stop valve leading to the air supply system to prevent the compressed air from flowing back to the part being overhauled. Never rely on check valves to isolate an air supply system.
