4. Preparation before Starting
1, Remove compressor from outer
packaging
2, DO NOT REMOVE TRANSIT PLUGS
BEFORE FITTING THE WHEELS.
3, Lie compressor on side to fit wheels and
dampers
4, Allow 5-10 minutes once compressor is
upright before starting.
5, Remove transit plugs and insert air filters
supplied
6, Insert oil breather plug supplied
7, The ideal place to set the compressor should be
clean, dry and well ventilated.
8, Keep the use voltage within + or –5%.
9, Keep the oil level within the red circle of the oil site
glass.
10, The recommend compressor oil is SAE30 over 10
deg, and SAE10 below 10 deg.
11, Set the pressure switch to the On position (Fig.2), let the
compressor run for 10 minutes with no load to ensure
lubrication of the moving parts before regular operation.
5. Operation and Adjustment
1, The compressor is controlled by a pressure
switch when in use. It will stop automatically
as pressure increases to the max setting, and
restart as pressure is reduced to the min setting.
The pressure switch pressure rating has been
set from factory and shouldn’t be adjusted
unnecessarily.
2, The outlet pressure of the compressed air can
be adjusted by the regulator valve. Rotate the knob on the
regulator by turning the regulating knob clockwise or
anticlockwise to increase or decrease air pressure.
3, To turn compressor off, press the red knob down to the Off
position.

6. Cautions
1, Never remove any connecting parts when the tank is under
pressure.
2, Never remove any electrical parts before isolating the
electrical supply.
3, Never adjust the pressure switch unnecessarily
4, Always ensure that the electrical supply is sufficient for the
compressor.
5, Never use the electrical plug to start or stop the compressor.
6, If the pressure switch isn’t working, switch off the machine
immediately to reduce any long term damage.
7, Replacement lubricant must be new and clean and should be
filled to the red cycle of the oil site glass.
8, Be sure to drain the tank daily.
9, Check oil level daily.
7. Maintenance
1, Clean crankcase and renew lubricant oil after the first 10
working hours.
2, Remove the drain valve to remove water from the tank daily
3, Replace air filters every 120 hours of use or as and where
they require replacement.
