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
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.
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
Check all nuts and bolts. Make
sure all loosened parts are
tightened before starting.
Remove the white travel plug
and attach the air filter, tighten-
ing hand tight only.
BEFORE USE
1. Ensure the power is OFF
by pushing in the power
switch.
PREPARATION FOR STARTING
2. Push in switch to OFF
position, and plug in power
cord at the wall.
3. Pull up the red power switch
and run compressor unit for
30 minutes to break in the
pump parts.

PREPARATION FOR STARTING
4. Turn regulator knob fully
counterclockwise to cause
air to bleed off.
5. Attach the hose and tool
to the compressor using the
Euro type quick release cou-
plings on 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 the motor is switched off the compressed air in the
discharge pipe should be released through the drain-cock. This
is a necessary condition before restarting or the motor will be
damaged.
OPERATION AND ADJUSTMENT

PAGE 12
OPERATION AND ADJUSTMENT
3. The output pressure of
compressed air can be regulated by
using the regulating valve. turn the
regulation valve knob clockwise to
increase the pressure.
4. When the compressor needs
to be stopped, set the power
switch to the ‘OFF’ position.
OPERATION AND ADJUSTMENT
5. If the compressor should
overheat, the Thermal Overload
will intervene and shut down the
compressor. Should this happen,
switch OFF the machine by
pushing the STOP/START switch
downwards, and wait for at least
5 minutes before pressing the red
RESET button underneath the air
filter and try to start the compres-
sor again.

1. Disconnect power source then release all pressure from the sys-
tem before attempting to install, service, relocate or perform any
maintenance.
2. Check compressor often for any visible problems and follow
maintenance procedures each time compressor is used.
3. Pull ring on safety valve and allow it to snap back to normal posi-
tion. Safety valve must be replaced if it cannot be actuated or it
leaks air after ring is released.
4. Turn compressor off and release pressure from system. Drain
moisture from tank by opening drain cock underneath tank.
5. Clean dust and dirt from motor, tank, and airlines and pump
cooling fins while compressor is still OFF.
6. IMPORTANT: Locate unit as far from spraying area, as hose will
allow preventing overspray from clogging filter.
7. Unclip the air filter cover, remove the filter and blow away any
loose dirt. If damaged or badly contaminated, it must be re-
placed.
8. Clean the fins of the compressor cylinder and the cylinder head
to receiver pipe. A clean compressor will work more efficiently.
9. LUBRICATION This is an oilless type compressor requiring no
lubrication.
MAINTENANCE 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.
