GENERAL MACHINE USE AND CARE
1. Prior to use, all operators should become familiar with the instructions in this
booklet especially the ON/OFF switch for emergency stopping.
2. ALWAYS maintain the compressor with care and keep it clean for best /
safest performance.
3. NEVER use this compressor if any part is damaged. Have it inspected and
repaired by your dealer.
4. NEVER attempt to modify the air compressor, tank, fittings or attachments in
any way. Doing so will invalidate the guarantee and could result in
personal injury.
5. NEVER abuse the power cable. NEVER pull on the cable when removing
the plug from the socket, or lift the compressor by the power cable.
6. Try to AV O I D using extension leads. Where possible use a longer airline hose
instead.
7. If you have to use an extension lead,ONLY use one that is of an
appropriate power rating and suitable for the work environment. Extension
leads must have an earth connection. Inspect the extension lead regularly
and replace if damaged.
8. ONLY USE RECOMMENDED PARTS: To avoid the risk of bursting, only hoses
with a rated pressure of 10 bar, or more should be used. NEVER attempt to
repair damaged hoses.
9. NEVER abuse the compressor by standing on it.
AIRLINE HOSES
1. ALWAYS ensure that equipment or power tools used in conjunction with the
compressor have a safe working pressure exceeding that of the machine.
2. ALWAYS keep the air hose away from any attached power tools and
ensure that the operator is not restricted by the length of the hose.
3. ALWAYS take care when a long air hose is required in the work area as it
presents a trip hazard. Coil the hose away as soon as the job is finished.
4. ALWAYS avoid kinking or trapping the air hose. ALWAYS replace faulty
hoses and NEVER attempt a repair if a leak is detected.
5. NEVER abuse hoses or connectors. NEVER carry an air tool by the hose, or
yank it to disconnect from the air supply. Keep hoses away from heat, oil
and sharp edges. Check hoses for leaks or worn condition before use and
ensure that all connections are secure.
6. ALWAYS ensure that the air supply is turned off at the machine outlet and
any air pressure vented from within the compressor and any attached
equipment when disconnecting air hoses or other equipment.

AIR COMPRESSOR SAFETY INSTRUCTIONS
1. ONLY USE WITHIN THE RECOMMENDED OPERATING TEMPERATURE RANGE:
This compressor should only be used in an ambient temperature of
between 0OC and +35OC (never below freezing temperatures).
2. NEVER USE AN AIR COMPRESSOR WHICH APPEARS DEFECTIVE OR IS
OPERATING ABNORMALLY: If the compressor operates unusually or makes
strange noises, switch off immediately and purge the air reservoir. Arrange
repairs with your nearest dealer.
3. BREATHING QUALITY AIR: This compressor should not be used to supply
breathing quality air.
4. SAFETY VALVE: NEVER remove or attempt to adjust the safety valve. The

other accumulations.
5. AVOID UNINTENTIONAL STARTING: DO NOT move the compressor when it is
connected to the mains power supply.
6. BEFORE EACH USE CHECK THE COMPRESSOR AND HOSE FOR DAMAGED
PARTS: NEVER use the compressor if it has been damaged in any way. Have
the compressor repaired by a qualified service engineer. DO NOT use the
compressor if the On/Off switch does not operate correctly.
7. KEEP THE MOTOR AIR VENTS CLEAR: Keep the motor vents clear and free
from dust. Wipe regularly to maintain an adequate supply of clean air.
AV O I D using in dusty conditions.
8. OPERATE THE COMPRESSOR AT THE CORRECT VOLTAGE: Make sure that the
mains supply voltage is the same as the voltage shown on the label.
9. ALWAYS adjust the pressure regulator to the recommended setting for the
particular spray gun or air tool being used.
10. When using the compressor for painting:
•DO NOT work in enclosed areas or near naked flames.
• Ensure that the area in which you are working has good ventilation.
• Protect your nose and mouth with a suitable face mask.

ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity
supply is the same as that indicated on the rating plate. This product is
designed to operate on 230V AC 50Hz. Connecting it to any other power
source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to
change the fuse in the plug, the fuse cover must be refitted. If the fuse cover
becomes lost or damaged, the plug must not be used until a suitable
replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due
to damage, it should be cut off and a replacement fitted, following the wiring
instructions shown below. The old plug must be disposed of safely, as insertion
into a mains socket could cause an electrical hazard.
If the colours of the wires in the power cable of this product do not correspond
with the markings on the terminals of your plug, proceed as follows.
•TheBlue wire must be connected to the terminal marked Nor
coloured Black.
•TheBrown wire must be connected to the terminal marked Lor
coloured Red.
•TheYellow and Green wire must be connected to the terminal
marked E or or coloured Green.
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD). If in any doubt, consult a qualified
electrician. DO NOT attempt any repairs yourself.
WARNING! READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE
MAINS SUPPLY.

ON/OFF PRESSURE SWITCH
Switch on - Auto/Off. The compressor will automatically switch off when the
tank pressure reaches the maximum preset pressure (0.8Mpa, 8 Bar, 116psi)
and will run automatically when the tank pressure reaches the minimum
preset pressure (0.6Mpa, 6 Bar, 87psi). In the ‘OFF’ position, the compressor will
not operate. This switch should be in the ‘OFF’ position when connecting or
disconnecting the power cord from the electrical outlet or when changing air
tools.
REGULATOR
1. The regulator adjusts the air pressure to fit an air operated tool, spray gun
of sandblaster.
2. To adjust the outlet air pressure, turn the regulator clockwise or
counterclockwise to suit the type of tool you are using.
SAFETY VALVE
This valve will automatically release compressed air when the pressure in the
tank exceeds the allowed pressure.
DISCHARGE PIPE
This pipe connects the pump head to the check valve. CAUTION: It is hot
when the compressor is running.
CHECK VALVE
The check valve is a one way valve allowing compressed air to enter the tank,
but prevents compressed air in the tank back into the pump.
DRAIN VALVE
This valve located at the bottom of the tank is used to exhaust water from the
tank. Make sure the pressure gauge of the tank is below 1 Bar to open it. Open
the drain valve to exhaust water in the tank, closing it tightly. NOTE: This action
should be done at least every week.
PRESSURE GAUGES
There are 2 pressure gauges on this type of compressor, one shows the
pressure in the tank and the other one shows the outlets pressure after the
regulator has been set.
