Installation Instructions

Operation Instructions:
A:Before Operation:

1. Confirm the voltage of the power supply and the power indicator light is lit.
2. Please open the leak valve of the oil & gas tank, drain the condensed water and immediately close the leak valve when oil leaks out.
3. Please check the oil level and keep it between indicator oil level.
4. Water cooled system , confirm that cooling water supply is normal.
5. When generator driving the belt, please check the belt tension correctly, not too loose or too tight.

B:Start up

1. Main power switch in.
2.  Press the start button to turn on the motor, working indicator light is on.
3. Check the discharge pressure gauge and lubricating oil pressure gauge are in correct indication.

C:Operation
  Please keep the exhaust temperature between 75ºC-95ºC to avoid condensation and precipitation and emulsify the oil.
D:Stop

1. Press the "off" button, about 10-15 seconds later, the delay electromagnetic valve acts, and the compressor stops running.
2. Turn off the power.
3. Don't use the emergency stop button in case of non emergency.

E: Precautions:

1. For initial start-up and after motor maintenance, determine the running direction of the press (as indicated by the arrow).
2. Do not mix different brand of river lubricating oil.
3. Change the consumables, lubricating oil and detail operation method, please refer the instruction manual.
