WARNING SYMBOLS

READ THIS INSTRUCTION MANUAL CARE­FULLY 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 re­moved.

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 com­pressor, 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 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.

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.

PAGE 7

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

PAGE 8

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.

PAGE 10

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.

PAGE 12

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

OPERATION AND ADJUSTMENT

PRESSURE GAUGES

There are two pressure gauges
on the compressor.

1. The pressure gauge on the
RIGHT shows the current pres­sure 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.

PAGE 15

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 month­ly, 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 care­fully cleaned in warm soapy water.
Rinse and let the filters dry com­pletely 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.
