Adjusting The Output Pressure

The output pressure of the regulated pressure outlet can be adjusted 

to suit the air tool connected and the task at hand.

1.  To do so, first decrease the 

pressure to 0psi by turning 

the pressure regulator anti-

clockwise.

2.  Then turn the pressure 

regulator clockwise until the 

desired pressure is shown on 

the regulated pressure gauge.

WARNING! 

DO NOT ATTEMPT TO ADJUST/MODIFY 

THE SAFETY VALVE IN ANY WAY. THE SAFETY 

VALVE INSTALLED ON THIS AIR COMPRESSOR 

IS DESIGNED TO AUTOMATICALLY RELEASE 

PRESSURE IN CASE OF EXCESS PRESSURE BUILD 

UP IN THE TANK.

3. USAGE

Starting Up The Compressor

For best practice, the compressor should be run without any load 

for 20 minutes before first use to lubricate the bearings and piston. 

This procedure should also be performed if the compressor has been 

stored for 6 months or more without operation.

1.  Disconnect all air hoses from 

the outlets and open the drain 

valve fully with a spanner 

to prevent pressurised air 

buildup in the tank.

2.  Make sure the power switch 

is in the off position. Plug 

the power supply cord into a 

mains outlet and turn the unit 

on. 

3.  Allow the compressor to run for 20 minutes without any loads/tools 

attached and any liquid to drain from the tank.

4.  Turn off the compressor and 

close the drain valve. The 

compressor is now ready for 

use.

5.  Attach the desired tool to one end of an air hose and the air hose to 

an outlet depending on the tool or application.

6.  Turn the compressor back on and adjust the regulated pressure to 

the desired level once the pump has shut off and the compressor 

has reached cut-off pressure 

(8bar).
