WARNING: Each device with different max working pressure. To reduce the risk
of exceed pressure. Make sure the max work pressure for each device. Rated
pressure in the system can not exceed the max pressure of any device. Or there
will be burst, explosion, malfunction, serious damage.
Remind:
Pump can not operate with empty load. Or the speed will be very fast which will
self-damage.
If acceleration is too fast or running very slow, Should stop operation and check that if there is

above instruction.
• To get perfect result, set up the min air pressure for each device.
• Pump can not operate under empty load.
• Relief pressure before close the pump.
TROUBLE SHOOTING
