WARNING SYMBOLS
READ THIS INSTRUCTION MANUAL CARE-
FULLY BEFORE OPERATING OR ADJUSTING
THE COMPRESSOR.
Risk of electric shock. The compressor must
be disconnected from the mains supply before
maintenance or removing any covers. Do not
use in a damp environment.
Risk of accidental start-up. The compressor
could start automatically in the event of a
power cut and subsequent reset. Do not carry
the compressor while it is connected to the
power source, or when the tank is filled with
compressed air.
This compressor contains surfaces which may
reach a high temperature during operation.
Never operate with the motor housing re-
moved.
Air and condensation water can burst from the
compressor when the drain plug is removed.
Wear a safety goggles and ear protectors
when using this compressor.
This compressor produces a high sound level
during operation. Ear protection should be
worn.

TRAINING: Prior to use, all users must become familiar with the instruc-
tions given in this manual. In particular, become familiar with the ON/OFF
control for stopping the compressor in the event of an emergency.
ALWAYS USE EYE PROTECTION: When operating the air compressor, al-
ways use eye protection such as goggles, and make sure that other people
in the work area are also using eye protection. Eye protectors must pro-
vide protection from flying particles both from the front and from the side.
PROTECT YOUR HEARING: Hearing protection should be worn when
operating this compressor, use ear plugs or ear defenders.
NEVER TOUCH MOVING PARTS: Never place your hand near any moving
parts on the air compressor or operate with the covers removed.
PROTECT YOUR SELF AGAINST ELECTRIC SHOCK: Never operate the
air compressor in wet or damp locations.
DRESS PROPERLY: Loose clothing or jewellery may be caught in moving
parts. Always tie long hair back, and wear suitable clothing.
KEEP VISITORS/CHILDREN AWAY: Do not allow visitors/children to han-
dle the air compressor or attachments and ensure that any people in the
work area are suitably dressed.
KEEP THE WORK AREA CLEAN: Cluttered areas mean accidents, so clear
the work area of all unnecessary tools, debris and furniture.
SAFETY PRECAUTIONS
DO NOT TOUCH HOT SURFACES: During operation, the motor, con-
nections, compressor body, cylinder head and tubes may get hot, do not
touch.
DO NOT DIRECT AN AIR STREAM AT THE BODY: Do not direct the
air stream at people or animals, as injury may result. Compressed air can
cause soft tissue damage and propel dirt and other particles at high speed.
BREATHING AIR: This compressor should not be used to supply breathing
quality air. Never use it as breathing apparatus.
STAY ALERT: Watch what you are doing, use common sense, and do not
operate the air compressor when you are tired. The air compressor should
not be used if you are under the influence of alcohol, drugs or any medica-
tion that makes you drowsy.
DISCONNECT THE AIR COMPRESSOR: Always disconnect the air com-
pressor from the mains power supply and decompress before performing
maintenance, changing any parts and when not in use.
MAINS POWER CABLE PRECAUTIONS: Never pull on the cable when
removing the plug from the mains socket, or lift the compressor by the
mains cable.

AVOID UNINTENTIONAL STARTING: When connecting the air compres-
sor to the mains supply make sure the red button on top of the air com-
pressor is in the OFF (down) position.
STORE THE AIR COMPRESSOR PROPERLY: When not in use the air com-
pressor should be stored in a secure, dry place out of the reach of children.
Always lock up the storage area.
MAINTAIN THE AIR COMPRESSOR WITH CARE: If the air compressor is
damaged in any way, have it repaired by a qualified engineer.
DO NOT USE EXTENSION LEADS: Using extension leads can cause your
compressor motor to burn out. Only use extension hoses.
DISPOSAL INFORMATION: The air compressor should be disposed of in
a safe an environmentally friendly manner. Contact your local Council for
disposal assistance.
DO NOT WELD TO THE PRESSURE VESSEL: Do not weld or modify the
pressure vessel in any manner.
SAFETY PRECAUTIONS ASSEMBLY
1. Remove the travel plug
2. Attach the air filter, tightening
hand tight only
3. Remove the travel plug
4. Fit the breather plug

BEFORE USE
1. Set the ON/OFF switch to the-
OFF position (pushed down).
2. Make sure that the compressor is
on level ground.
3. Check that the oil level is half way
up the oil sight glass
4. If not, remove the breather plug
and fill with compressor oil (our
part code SO2068)
OPERATION
1. Attach a hose to the quick re-
lease coupler on the compres-
sor and to an air tool.
2. Turn the compressor on by
lifting the on/off button. The
compressor will operate until
the tank is fully pressurised
before switching off. The com-
pressor will start again when
the tank pressure drops.

OPERATION SWITCHING OFF
1. Push down on the on/off switch
to turn the compressor off.
2. Operate the air tool to depres-
surise the air hose.
3. Disconnect the tool from the
hose.
4. Open the drain cock to remove
any condensation from the
compressor.
3. Set the regulator to the correct pressure for the air tool (check in the
air tool manual). The output pressure is shown on the right gauge.
The left hand gauge shows the tank pressure.

1. The compressor is controlled by a pressure switch. It can be stopped
automatically as the pressure increases to the maximum and restarted
as pressure decreases to the minimum. The rated pressure has been
adjusted during the manufacturing process - don’t alter it carelessly.
PRESSURE ADJUSTMENT THERMAL RESET SWITCH
This compressor has a thermal overload device.
If the motor gets too hot, the thermal overload device cuts the power
which prevents damage to the motor.
If the thermal overload device operates, let the motor cool down for 5
minutes and push the reset button.
If you start the compressor and the overload cutout operates again, stop
the compressor and disconnect from the power supply and have your
compressor examined by a qualified service agent.

1. Disconnect power source then release all pressure from the system be-
fore attempting to install, service, relocate or perform any maintenance.
2. Never unscrew any connecting part when the tank is pressurised.
3. Never disassemble any electrical part before disconnecting the plug.
4. Never adjust the safety valve carelessly.
5. Never use the compressor where voltage is too low or too high.
6. Never disconnect the plug to stop the compressor, set the switch knob
to the off position instead.
7. Lubricating oil must be clean and at the level indicated.
8. Clean crankcase and renew lubricating oil after the first 10 working
hours. Check the oil level after every 20 working hours, and replenish if
necessary.
CAUTIONS MAINTENANCE
CLEAN THE AIR FILTERS (MONTHLY)
The air filters must be examined monthly and
more often in dusty conditions:
1. Unscrew the filters from the compressor.
2. Remove the filter covers from the filters.
3. Clean the sponge and the filter cover
using a soft brush. If necessary, the filters
can be carefully cleaned in warm soapy
water. Rinse and let the filters dry com-
pletely before refitting.
4. Make sure that the filters and filter cov-
ers are replaced into position. If the
filters are damaged, you must replace
them.
CLEANING
1. Open drain cock under the tank to ex-
haust condensate after every use.
2. Clean the crankcase and renew the oil,
clean air filter, and check safety valve and
pressure gauge after every 120 working
hours.
