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 thepower 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.

PAGE 4

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 5

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.

SAFETY PRECAUTIONS

PAGE 6

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 7

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

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.


PAGE 9

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.

PAGE 10

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.


PAGE 11

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


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.


PAGE 13


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.

PAGE 14

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


PAGE 15

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.
