OPERATION

WARNING! ENSURE THAT YOU HAVE READ, UNDERSTOOD AND APPLIED SECTION 1 SAFETY INSTRUCTIONS.
‰
6.1. Make sure that the main switch (fig.3.1) is 'OFF' (down).
6.2. Check the oil level by looking through the sight glass (See fig.2B).
6.3. Ensure that the tank drain valve is closed (fig.5).
6.4. Close the outlet pressure regulator by turning the knob clockwise (fig.3.2).
6.5. Connect the air tool required to the compressor via an air line connected to the air outlet.
6.6. Plug the mains cable into the mains supply and start the compressor by pulling up the main switch (fig.3.1).
6.7. Allow the pressure in the tank to rise to the maximum at which point the compressor will automatically cut out. Tank pressure is shown on
the larger gauge (fig.3.5).

6.8. Begin to gradually open the regulator by turning the knob until the small gauge registers the required operating pressure specified for the
tool to be used. Always adjust up to the required pressure rather than down from a higher pressure. The required setting, once achieved,
can be locked by screwing the locking ring (fig.3.3) up tight underneath the adjusting knob.
6.9. You can now begin to use the tool. The compressor will operate automatically cutting in and out as required to restore the air pressure in
the tank. The pressure switch (fig.3.7) stops the motor when the maximum tank pressure is reached and restarts it when pressure falls
below the minimum threshold - approximately 2bar (29psi) less than the maximum pressure.
Note: a) If the motor does not cut in and out, but runs continuously when using an air appliance, the capacity of the compressor may be
too small for the appliance.
b) The main gauge (fig.3.5) indicates the pressure inside the main tank, NOT the pressure supplied to the air equipment, which is
shown on the smaller gauge (fig.3.4). Should the pressure in the main tank exceed the pre-set switch (fig.3.7) maximum, the safety valve
(fig.3.6) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the switch or the safety valve.
‰
6.10. When the compressor is not being used set the regulated
pressure to zero so as to avoid damaging the pressure regulator.
6.11. To stop the compressor press down the main switch (fig.3.1).
6.12. When the compressor stops there will be a whistling sound as compressed air is vented from the compressor head.
DO NOT, other than in an emergency, stop the compressor by switching off the mains power, or by pulling the plug out, as the pressure
8
relief will not then occur and motor damage may result upon restart.
6.13. When you have finished using the compressor unplug the unit from the mains power supply.
6.14. Set the outlet pressure on the regulator to zero.
6.15. Remove the air line and air tool.
6.16. The tank must now be drained. This will release the air left in the tank and drain away condensation that may have formed within the
tank. Choose a suitable location for this operation and/or make provision to collect the condensation. Wear ear and eye protection.
Open the tank drain valve (See fig.5) slowly allowing air and moisture to bleed from the tank. After bleeding close the drain valve to
prevent debris building up in the valve.
WARNING! Water that is allowed to remain in the tank during storage will corrode and weaken the air tank which could cause the tank to
‰
rupture. To avoid serious injury drain the tank after each use or daily.
