Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly,
and shorten the machine’s service life. Clean the body of your machine with a soft brush,
or dry cloth. If available, use clean, dry, compressed air to blow through the ventilation
holes
• Use a mild detergent and a damp cloth to clean parts contaminated with oil. Rinse with
fresh water and dry thoroughly
• Keep all electric and electronic components dry at all times
Depressurising the air tank
• If it is necessary to release residual air pressure from the air tank, disconnect the
compressor from the mains power supply and pull the ring in the centre of the Pressure
Release Valve (8) outwards
• Residual air will escape from the valve until the ring is released, or all air pressure is
released
Draining
• During use, atmospheric moisture will condense in the air storage tank. The tank should
be drained of moisture on a regular basis to avoid corrosion damage
• To drain moisture, open the Drain Cock (13), located on the underside of the tank, approx.
3 turns anti-clockwise
• Allow all moisture to drain and retighten plug
Air filter maintenance
WARNING: Never run this compressor without the air filter element fitted, as this would lead
to rapid wear of internal components, causing permanent internal damage and shorten the
service life of this compressor.
Adjusting line pressure
• The pressure of the air supplied to the tool (line pressure) can be adjusted using the
Pressure Regulator (11). The line pressure is displayed on the Pressure Gauge
• Increase the line pressure by rotating the pressure regulator clockwise. To reduce the line
pressure, rotate the pressure regulator anti-clockwise
Accessories
A range of accessories, including an Air Filter, Air Regulator, Air Impact Wrench, as well as
a variety of spray guns, are available from your GMC dealer. Spare parts can be purchased
from your GMC dealer or online at www.toolsparesonline.com

and oil-resistant gloves, when carrying out maintenance on this compressor. ALWAYS ensure
proper ventilation.
WARNING: If oil is removed during maintenance, fill into suitable sealed containers and
dispose of according to laws and regulations.

completely cooled, before cleaning or carrying out any maintenance (with the exception of oil
removal; refer to ‘Changing the motor oil’).
Note: The maintenance schedule should be adjusted according to use and environment.
If the compressor is used frequently, and/or if it is used in harsher environments, shorter
