ADJUSTING THE PRESSURE
To adjust the outlet air pressure, use the red coloured regulator knob 
and check the pressure on the outlet pressure gauge, Pic. 8.
If the pressure needs to be lower, turn anti clockwise. 
If the pressure needs to be higher, turn clockwise.
Use the gauge to ensure you set the correct working pressure.
Note: Different air tools require different operating  pressures. Always 
check with the tool manufacturer if unsure.
SAFETY VALVE
Pic. 9
NOTE: When checking the safety valve ALWAYS wear safety glasses.
To check the operation of the safety valve the air tank will need to be 
full. 
Portable
Tip compressor backwards, the safety valve is located under the 
compressor. Gently pull the ring outwards. This should release air 
under pressure. Release the ring and when the pressure has dropped 
the air flow will stop. Note: there will still be some air left tin the tank.
Wall Mounted
Remove compressor from the wall mounts. Place on stable ground or 
table. Then follow steps above under PORTABLE. Securely remount the 
compressor on the wall before using.
If the safety valve does NOT work in this manner, STOP the air 
compressor immediately and have the air compressor 
checked / serviced by an authorised service centre.
