MAIN COMPONENTS 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.

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
Attach the wheels to the compressor.
Fit in the rubber stopper as shown.

BEFORE USE
1. Examine the machine for signs of transit damage. If damaged, call SGS
Customer Service immediately.
2. Avoid long air lines and slong supply lines (extensions).
3. Make sure the intake air is dry and dust free. Do not set up the
compressor in damp or wet rooms.
4. The compressor may only be used in suitable rooms, with good ventila-
tion and ambient temperature between 5° and 40° Celsius. There must
be no dust, acids, vapors, explosive or inflammable gases in the room.
5. Set up only on flat and stable surfaces.
6. Use flexible hoses in order to ensure proper airflow.
7. Supply hoses at pressures above 7 bar should be equipped with a safety
cable (e.g. a wire rope).
OPERATION
1. Attach a hose to the quick release coupler on the compressor 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
compressor will start again when the tank pressure drops.
3. Check the safety cut off valve is working correctly - pull on the ring to
release air. When you release the ring the air should stop. If the valve
does not operate correctly do not use the compressor.
4. 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. Push down on the on/off switch to turn the compressor off.
2. Operate the air tool to depressurise the air hose.
3. Disconnect the tool from the hose.
4. Open the drain cock to remove any condensation from the compressor.

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.
2. As soon as motor switched off the compressed air in the discharge pipe
should be released through the release valve under the switch. This is
the necessary condition for restart, or the motor will be damaged. The
rated pressure can be adjusted by turning the adjusting bolt of the
switch
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 min-
utes 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. Put the cover off first and put on the breath pipe and air filter before
the compressor run.
2. Never unscrew any connecting part when the tank is in pressure condi-
tion.
3. Never disassemble any electrical part before disconnecting the plug.
4. Never adjust the safety valve carelessly.
5. Never use the compressor in place where voltage is too low or too high.
6. Never disconnect the plug to stop compressor, set the switch knob in
position off instead.
7. If the release valve doesn’t work as motor stopped, find the cause im-
mediately so as not to damage motor.
8. Lubricating oil must be clean, oil level should be kept in the score of oil
ruler.
9. Disconnect the plug to cut off power supply and open the outlet valve
CAUTIONS MAINTENANCE
CLEAN THE AIR FILTERS (MONTHLY)
The air filters must be examined monthly and more often in dusty condi-
tions:
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 completely before refitting.
4. Make sure that the filters and filter covers are replaced into position. If
the filters are damaged, you must replace them.
CLEANING
1. Clean crankcase and renew lubricating oil after the first 10 working hours.
2. Clean the oil level after every 20 working hours, and replenish if neces-
sary.
3. Open drain cock under the tank toexhaust condensate after every 60
working hours.
4. Clean crankcase and renew the oil, clean air filter, and check safety valve
and pressure gauge after every 120 working hours.
