Air Compressor Use and Maintenance

Turn on (if not already)

Make sure that the power supply voltage is the same with what’s indicated on the data label: 230V/50 Hz or 115V/60 Hz. Use only 3-pole receptacles that accept the compressor’s plug.

The on/off switch is located on the top of the pressure switch. To switch the unit on, turn the switch to position “1”. When switched on, the compressor starts to build up pressure until the tank reaches the maximum allowed pressure (8 bar/120 psi). The unit will then be automatically

switched off until air is used and the pressure in the tank drops to the minimum operating pressure (6 bar/90 psi), at which point the compressor automatically switches on.

Check the outlet pressure

The outlet pressure can be adjusted using the knob on the filter/regulator so that the air output is enough for the application, but the output will not exceed the maximum air pressure specified by the application. Turn the knob clockwise to increase the pressure and counter-clockwise to decrease pressure.

Check for oil leaks, abnormal noise or vibration.

Check oil level through the sight glass weekly to make sure the oil level is aligned with the red marker line next to the sight glass. Add or remove oil as needed.

Check oil level.

Drain the condensate that has collected in the air tank. It may be necessary to do more often when operated in high humidity.

Drain the water collected in the air outlet filter.

Clean the compressor using a soft cloth. Wipe off any oil or dirt.

Check compressor efficiency (make sure all nuts and bolts are tight, check for air leaks, pressure hose wear, pipe fittings and electrical connections).

Check the air intake filter. Replace if necessary.

Replace oil.

Check pressure relief valve function.
