Pressure Gauges
The Tank Pressure Gauge supplies the reading of the air pre ssure inside the tank.
Pressure Regulator
This compressor is fitted with an Air Pressure Regulator. It allows regulation of the output air
pressure.
Some air tools require a higher operating pressure than others. Please refer to the air pressu re
requirements of your tools for the proper settings for the regulator.
NOTE. If you do not allow the air to discharge whilst you are setting the regulator, the pressure
as indicated on the regulated outlet gauge will be incorrect.
This gauge ONLY indicates the correct pressure while air is being discharged from the
outlet.
Safety Valve
The compressor is equipped with a saf ety valve that will engage when the pressure in the
tank exceeds the maximum pressure setting, releasing any excess built up.
DO NOT REMOVE OR ATTEMPT TO ADJUST THE SAFETY VALVE

Shutting Down Your Compressor
When you have finished using your compressor, follow these steps:-
1. Close the air outlet taps.
2. Switch off the compressor.
3. Disconnect unit from power outlet (power point).
4. Disconnect tools and / or Accessories from the air hose.
5. Disconnect the Air Hose.
6. Locate the drain valve on the underside of the tank.
7. Open the drain valve to release remaining pressurized air from within the tank. Moisture build
up in the tank is normal with air compressors, so a small amount of water may come out
while draining. (Draining the tank is vital for the lo ngevity and safety of your air
compressor).
8. Store the compressor in a cool, dry place.
Maintenance
1. The tank will require accumulated moisture to be drained from it on a regular basis. It is
recommended that the tank be drained of moisture after every 5 Hours of use. The drain
valve is located on the underside of the tank.
2. Check Oil level before each use.
3. Wash air filter insert in a mild soapy solution after 50 hours use. Operation in extreme
conditions e.g., dust, paint residue etc, may require more frequent cleaning.
4. Check handle is attached properly prior to us e.
6. Check power cord for signs of wear and tear before each use.
7. Never use caustic agents to clean any part of the compressor.
8. Remove dust and dirt regularly. Wipe down compressor with a damp rag. Do not use alcohol,
petrol or other cleaning agent as this presents a fire hazard.
