SAFETY PRECAUTIONS
WARNING!
Compressed air can be dangerous.
Follow these safety instructions carefully.
• Never direct a jet of compressed air at people or animals, or spray
paint towards people or animals.
• Use appropriate protective equipment, such as Clarke safety-
goggles or glasses, dust masks, ear defenders etc. when using
compressed air tools.
• Air compressors work at high pressure. Inspect equipment and hoses
regularly, checking for any damage or leaks. Have any damage
properly repaired before using the machine again.
• Do not operate the compressor with any guards removed.
• Do not adjust or tamper with the safety valve in any way. The maximum
working pressure (115 psi - approximately 8 bar) is clearly marked on
the compressor.
• The compressor will become hot during operation. Do not touch the
cylinder head or discharge pipe while the compressor is in use.
• Always release any pressure from the air hose (by operating the tool
briefly) before disconnecting any hoses or tools.
When paint spraying:
• Always wear a suitably approved breathing mask when paint
spraying, to protect against inhalation of paint spray or fumes.
An air feed mask may be required when spraying some types of paint.
If in doubt, check the paint manufacturers instructions.
• Make sure there is adequate ventilation. Do not spray in confined or
enclosed areas.
• Many paints are flammable. Do not smoke while spraying or preparing
paints, or spray near a naked flame or heat source.

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard 230 Volt (50Hz) electrical supply through
an approved BS1363, 13amp plug or a suitably fused isolator switch.
We recommend that the compressor is connected to the mains supply through a
Residual Current Device (RCD).
WARNING! THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the flexible cord of this appliance may not correspond with the
coloured markings identifying terminals in your plug proceed as follows:
• Connect GREEN & YELLOW cord to terminal marked with a letter “E” or Earth
symbol “ ” or coloured GREEN or GREEN & YELLOW.
• Connect BROWN cord to terminal marked with a letter ‘L’ or coloured RED
• Connect BLUE cord to terminal marked with a letter ’N’ or coloured BLACK
If this appliance is fitted with a plug which is moulded onto the electric cable (i.e.
non- rewirable) please note:
1. The plug must be thrown away if cut from the electric cable. There is a danger
of electric shock if it is subsequently inserted into a socket.
2. Never use the plug without the fuse cover fitted.
3. Should you wish to replace a detachable fuse carrier, ensure that the correct
replacement is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local dealer or most
electrical stockists.
5. The fuse in the plug must be replaced with one of the same rating (13amps)
and this replacement must be ASTA approved to BS1362.
If in doubt, consult a qualified electrician....DO NOT attempt repairs yourself
Fuse Replacement
The fuse in the plug must ASTA approved to BS1362and rated at 13 amps

MONZA SPRAY UNIT
OPERATION
Before connecting your Monza to the mains supply, check that:-
(A) The GREEN coloured ON/OFF Rocker switch is in the ‘O’ position.
(B) The pressure regulator on top of the machine is in the low pressure or ‘Start’
position i.e. turned fully anticlockwise.
Connect the spraygun or the other tool which is to be used to the air outlet of the
Monza using the air hose which is fitted with quick fit adaptors at each end. An air
tight seal is formed by the rubber washer. Screw the connection together by hand,
just sufficiently for a proper seal to be made - but do not over tighten. If the face
of a rubber seal becomes damaged, then it may either be turned over or otherwise
replaced.
NOTE:
Please refer to the manual provided with the spraygun for its operation and
maintenance.

For a professional looking finish paint must be thinned. If manufacturers recom-
mendations on thinning are not available, the following can be used as a
general guide.
Water based paints (emulsions) 10-20% water.
Oil based paints (gloss) up to 10% thinners.
Cellulose paints up to 50 % cellulose thinners.
HANDLING THE GUN
the first requirement for a good resultant finish is the proper handling of the gun.
The gun should be perpendicular to the surface being covered and moved par-
allel with it. The stroke should be started before the trigger is pulled and likewise ,
released before the stroke is ended. This gives accurate control of the gun and
material.
The distance between the gun and the surface to be covered should be 6 to 12
inches depending on the material and atomising pressure. The material depos-
ited should always be even and wet. Lap each stroke over the preceding stroke
to obtain a uniform finish.
NOTE: To reduce overspray and obtain maximum efficiency, always spray with
the lowest possible atomising air pressure.

PAINT SPRAYING HINTS
WARNING
NEVER attempt to spray unless you are wearing suitable, approved
respiratory and eye protection.
REMEMBER that some modern paints require specialist respiratory
protection...always consult the paint manufacturers instructions.
1. GENERAL PREPARATION
a. Ensure that the area in which you will be spraying is clean and dust free.
b. Connect spray gun to compressor via suitable flexible hose.
c. With no paint in spray gun, test system for air leaks.
d. Cover adjacent pieces of equipment to prevent overspray. Mask areas
of the article not to be sprayed.
e. Ensure surface to be painted is clean, dry and free from oil and dust.
Check paint manufacturer’s instructions for any special surface
preparation required.
REMEMBER - TIME SPENT PREPARING SAVES TIME SPENT FINISHING
2. PAINT PREPARATION
a. Achieve the correct paint viscosity. This should be done according to
paint manufacturer’s instructions, and will vary according to type of paint.
b. Having mixed the paint thoroughly in a separate container, pour into the
spray gun paint container through a fine filter.
DO NOT OVERFILL SPRAY GUN PAINT CONTAINER - three quarters full is maximum
c. It is usually best to experiment with a couple of practice spray coats on a
piece of material with the same type of surface as the article you wish to
spray, eg. metal for a car body panel, wood for a piece of furniture etc.

1. Ensure that the ON/OFF switch is in the off ‘O’ position.
NEVER USE THE MAINS SWITCH TO STOP THE MOTOR.
2. Depress equipment trigger (spraygun) to release air from the
hose and compressor before disconnecting from the machine.
3. Switch off and disconnect from the mains supply.
SHUTTING DOWN THE COMPRESSOR
Set the regulator to the desired operating pressure and then switch the machine
ON at the rocker switch. The Monza should start immediately.
However, if at any time it hesitates to do this, then immediately trigger the spraygun
or tool in order to release any built up pressure.
The air pressure may, within limitations, be increased by turning the control knob
clockwise or decreased by turning it anticlockwise.
You may need to experiment to find the setting best suited for a particular job.
When spraying paint, or similar material, it is usually best to operate at the lowest
pressure which gives a satisfactory finish.
The syphon spraygun supplied with your Monza Air Compressor is most versatile
and can be used to apply a variety of paint material. It features two basic controls:
1. Paint control knob at the rear of the spraygun which adjusts the position of
the main needle and consequently the volume of paint which can be sprayed.
Minimum paint flow is achieved by having this control screwed in (clockwise)
and vice versa.
2. A fan spray control located just to the side of the spray head will alter the
shape of the fan spray.
Refer to the spraygun manual for full details.

ROUTINE CARE AND MAINTENANCE
CAUTION
Before carrying out any of this service work, always disconnect the Monza from the
mains supply and if necessary allow the machine to cool down before starting
work. Do not attempt any repair or adjustment yourself if you are uncertain as to
how it should be done.
It is important to keep the Monza Air Compressor clean and this may be done
with the help of a small soft brush and vacuum cleaner. In particular the air intake
filter should be inspected periodically, so that it is always kept free of any dirt
particles, which if not cleaned away will affect the performance of the machine.
Also, particles must not at any time be allowed to pass through into the cylinder
head as this would adversely affect the valves, including possible damage, and
entail more extensive dismantling and cleaning.
MONTHLY:
Remove and clean the air intake filter element by carefully prising off
the plastic end cover (this should be carried out more frequently if the
compressor is used in dusty atmospheres).
With SPONGE ELEMENTS gently blow clean with compressed air or wash
in solution of household detergent.
Rinse and dry thoroughly before re-fitting.
Remember that a dirty filter prevents adequate aspiration and adversely
affects the efficiency of your compressor.
WARNING: Never operate the compressor without the air intake filter fitted.
YEARLY or 1000 HRS:
Replace the air intake element.
EVERY 2 YEARS or 2000 HRS:
Have the intake and delivery valves checked - see your Clarke dealer.
WARNING
Never unscrew a compressor connection while the machine is under pressure.
Always make certain all air is expelled before doing so .
SPRAYGUN
Please refer to the manual provided for its operation and maintenance
CAUTION Do not attempt any repair or adjustment if you are uncertain as
to how it should be done. If you have any queries, contact your local
