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
instructions 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 com-
pressor, always use eye protection such as goggles, and make sure
that other people in the work area are also using eye protection.
Eye protectors must provide 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 oper-
ate 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.
SAFETY PRECAUTIONS

PAGE 6
KEEP VISITORS/CHILDREN AWAY: Do not allow visitors/children
to handle 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.
DO NOT TOUCH HOT SURFACES: During operation, the motor,
connections, 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. Com-
pressed 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 medication that makes you drowsy.

DISCONNECT THE AIR COMPRESSOR: Always disconnect the air
compressor 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 compres-
sor by the mains cable.
AVOID UNINTENTIONAL STARTING: When connecting the air
compressor to the mains supply make sure the red button on top of
the air compressor is in the OFF (down) position.
STORE THE AIR COMPRESSOR PROPERLY: When not in use the
air compressor 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 com-
pressor 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.
SAFETY PRECAUTIONS

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.

ASSEMBLY
- Use a spanner to attach the wheels to the compressor.
- Use the washers and spring washer in the positions shown.
Insert the support foot
into the position shown.

PREPARATION FOR STARTING
1. Check all nuts and bolts.
Make sure all loosened parts
are tightened before starting.
2. Before running the compres-
sor remove the plug and con-
nect the breather pipe to the
oil-hole. (2.)
3. Screw both the air filters in
either side before starting the
compressor. (3.)
4. Set the compressor in a clean,
dry and ventilated area.
5. Keep voltage within ±4%
of the rated value.

PREPARATION FOR STARTING
5. Keep the oil level in the red
circle of the oil glass sight win-
dow. You can purchase compres-
sor oil from our website at:
www.sgs-engineering.com
6. Open the outlet valve, set
the power switch knob to posi-
tion “on” and let the compres-
sor run for 10 minutes with
no load to ensure the moving
parts are lubricated before
regular service.

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. As soon as the motor is switched off
the compressed air in the discharge pipe should be released
through the release valve under the switch. This is a necessary
condition before restarting or the motor will be damaged. The
rated pressure can be altered by turning the adjusting screw.

OPERATION AND ADJUSTMENT
PRESSURE GAUGES
There are two pressure gauges
on the compressor.
1. The pressure gauge on the
RIGHT shows the current pres-
sure in the reservoir tank.
2. The pressure gauge on
the LEFT shows the ‘user set’
outlet pressure. This can be
adjusted using the regulator.
2. The output pressure
of compressed air can be
adjusted by the regulat-
ing valve. Grip the regula-
tion valve knob and turn it
clockwise to increase the
pressure.

PAGE 14
OPERATION AND ADJUSTMENT
3. When the running compressor
needs to be stopped set the
pressure switch in the off
position.
4. Always vent the compressor
after each use by turning the
regulator knob fully anticlock-
wise.
5. Once the compressor is vent-
ed, remove any condensation
from inside the tank by unscrew-
ing the bleed nipple.

1. Before any maintenance operation
stop the air compressor, cut off the
power supply and discharge all air in
the air tank.
2. Clean crank case and renew lubri-
cating oil after the first 10 working
hours. Check the oil level through the
oil level sightglass (1.) after every 20
working hours and replenish if neces-
sary- you can replenish by unbolting
the oil level sightglass, and draining
off any old oil. (2.)
3. Have the safety valve and pressure
gauge checked by a certified repair
centre every 6 months to ensure they
are in the correct working condition.
4. Make sure there is no rust on the air
tank and the air tank is not damaged.
5. Have the thickness of the air tank
checked by a certified repair centre
every year to ensure the tank thick-
ness is not less than 2.1mm.

MAINTENANCE
CLEAN THE AIR FILTERS (MONTHLY)
The air filters must be examined month-
ly, more often in dusty conditions:
1. Remove the filter covers from the
compressor.
2. Remove the filter covers from the
filters.
3. Remove the filters from the filter
covers.
4. Clean the sponge and both the
filters cover using a soft brush.If
necessary, the filters can be care-
fully cleaned in warm soapy water.
Rinse and let the filters dry com-
pletely before refitting.
5. Make sure that the filters and filter
covers are replaced into position. If
the filters are damaged, you must
replace them.

MAINTENANCE
CHECK THE NON-RETURN
VALVE (EVERY 6 MONTHS)
If the reservoir pressure
decreases for no apparent
reason, it is possible that the
non-return valve is leaking.
To check:
1. Make sure that the reservoir
is not under pressure and the
compressor is switched OFF.
2. Examine the non-return
valve, and replace the gasket
and valve if necessary.

PAGE 18
THERMAL RESET SWITCH
There may be instances your compressor will overheat.
If it cuts out, this is a safety feature to protect you and your
compressor. Leave this compressor for a good while until you reset it.
If the compressor turns off again on re-set you should not keep
running it as it may be damaged and the system may be unsafe.
