FOR YOUR SAFETY
WARNING: AS WITH ALL MACHINERY, THERE ARE CERTAIN HAZARDS
INVOLVED WITH THEIR OPERATION AND USE. EXERCISING RESPECT AND
CAUTION WILL CONSIDERABLY LESSEN THE RISK OF PERSONAL INJURY.
HOWEVER, IF NORMAL SAFETY PRECAUTIONS ARE OVERLOOKED, OR
IGNORED, PERSONAL INJURY TO THE OPERATOR, OR DAMAGE TO
PROPERTY MAY RESULT. IT IS IN YOUR OWN INTEREST TO READ AND PAY
ATTENTION TO THE FOLLOWING RULES:
GENERAL PRECAUTIONS
ALWAYS
• ensure that all individuals using the compressor have read and fully
understand the Operating Instructions supplied and are suitably trained
• stop the engine and ensure the pressure is expelled from the air receiver
before carrying out any maintenance.
• ensure that there is adequate ventilation when spraying flammable
materials e.g. cellulose paint, and keep clear of any possible source of
ignition.
• protect yourself. Think carefully about any potential hazards which may
be created by using the air compressor and use the appropriate
protection. e.g. Goggles will protect your eyes from flying particles. Face
masks will protect you against paint spray and/or fumes. Ear defenders
will prevent hearing damage caused by load noise.
• consult paint manufacturers instructions for safety and usage, before
spraying
• ensure that the air supply is turned off at the machine outlet and all
pressurised air from the machine and other equipment attached to it, is
expelled BEFORE disconnecting air hoses or other equipment.
• make sure that children and animals are kept well away from the
compressor and any equipment attached to it.
• ensure that any equipment or tool used in conjunction with your
compressor, has a safety working pressure exceeding that of the
machine.
DO NOT
• direct a jet of air at people or animals, and NEVER discharge
compressed air against the skin. Compressed air CAN BE dangerous!

• leave pressure in the receiver overnight, or when transporting.
• adjust, or tamper with the safety valves. The maximum pressure is
factory set, and clearly marked on the machine.
• operate in wet or damp conditions. Keep the machine dry at all times.
Similarly, a clean atmosphere will ensure efficient operation. Do not use
in dusty or otherwise dirty locations.
• touch the machine until it has cooled down...some of the metal parts
can become quite hot during operation.
• operate your compressor with any guards removed.
FIRE PREVENTION
ALWAYS
• switch the engine OFF when refuelling.
• refuel away from any source of heat.
• refuel in a well ventilated area.
DO NOT
• overfill the tank, fill to the level specified.
• smoke whilst refuelling and avoid smoking or using a naked flame near
the compressor.
• start the engine if there is spilled fuel. Any spillage must be wiped clean
and the compressor allowed to dry before attempting to start the
engine.
EXHAUST GAS PRECAUTIONS
ALWAYS
• Make sure that there is adequate ventilation when using the
compressor.
• Position the compressor so that the exhaust is pointed away from people
or animals.
DO NOT
• use the compressor indoors or in an enclosed area. (i.e. in a warehouse,
tunnel, well, hold etc.)
WARNING: EXHAUST FUMES CAN BE FATAL

GENERAL NOTES
• NEVER allow anyone, not fully familiar with compressors, to use this
equipment.
• DO NOT alter the engine settings....these settings are set at the factory.
Should they need re-calibration - consult your Clarke dealer
RESIDUAL RISK
Although this manual contains extensive safety warnings and information on
the safe operation of your compressor, every tool does have certain residual
risks which cannot be completely excluded with warnings or safety devices.
This compressor must therefore always be operated with caution.
OVERVIEW

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 7
PREPARATION FOR USE
A. ENVIRONMENTAL
• Ensure the compressor is sited on a firm level surface.
• Ensure the environment is dry and dust free.
• Ensure there is adequate ventilation for: (a) Air intake to compressor
pump, (b) Cooling for compressor pump, (c) Engine exhaust gases.
B. ENGINE
Check oil and fuel levels and a visual check of components. Refer to engine
service manual.
C. PUMP
• Check oil level on the sightglass - to level marked.
D. FUELLING
Fill with unleaded petrol, according to the instructions within the engine manual.
• Ensure the fuel tap is set to the required position.
• Ensure The fuel hose and connectors are intact, in perfectly serviceable
condition and there is no leakage.
NOTE: Always use a funnel to fill the fuel tank so as to avoid accidental
spillage of fuel. If fuel is spilled it must be removed from the unit
and surrounding area, before attempting to start the engine.
E. RECEIVER
• Drain off any condensate, by opening the drain cock (see Fig. 1).
Remember to close the drain cock when completed.
NOTE: This should be carried out DAILY when the compressor is in
constant use.
F. AIR HOSE & AIR TOOL
• Attach the air hose to the outlet using an appropriate connector.
• Attach the air tool/spray gun to the air hose...If using snap couplings, use
a whip end, available from your Clarke dealer.

STARTING THE COMPRESSOR
FIG. 2
INITIAL START-UP
1. Fully open the receiver drain cock, (located between the wheels).
2. To ease starting, ensure there is no pressure in the pump outlet manifold by
opening the Bleed Valve (See Fig.2).
3. Start the engine, according to the instructions contained in the engine
service manual, if this is the first time you use the compressor, allow to run
for 10 minutes.
4. After a ten minute period, close the drain cock and bleed valve then
ensure both air outlet taps are closed (off position).
• Pressure will build up in the receiver and eventually the air governor will
operate so that the engine runs off load. The pressure registered on the
pressure gauge should be 100psi.
5. Slide the outlet taps outwards to allow air to escape from the outlets, and
slowly turn the pressure regulator clockwise. Observe the pressure gauge.
When the pressure has dropped by approx. 20psi, the Air Governor/Load
genie will operate and the compressor will cut in again. Close the sliding
outlet valves and pressure in the air receiver will once again increase
6. Finally, stop the engine and set the pressure regulator to zero pressure
(turned fully anticlockwise) and attach the air hose and air tool.
7. Open the sliding valves then set the pressure regulator to full pressure
(100psi) and check for air leaks at the tool and connectors.
• If leaks are apparent, set
the regulator to zero
pressure (fully
anticlockwise), press the
trigger of the tool to
ensure no air is present in
the airline, then rectify the
problem before
proceeding.
• If no leaks are evident,
Open the bleed valve,
start the engine and then
close the bleed valve. Set
the outlet pressure to the
desired value and proceed to use the air tool in accordance with the
manufacturers instructions.

WHEN STARTING SUBSEQUENTLY, START THE MACHINE AS FOLLOWS:
Illustrative
purposes
only
FIG. 3
1. At the beginning of the day, open the drain cock and allow any
condensate to drain completely, then close the drain cock.
2. To ease starting, ensure there is no pressure in the pump outlet manifold by
opening the Bleed Valve (See Fig.2 on page 8).
3. Connect the air hose to one of the outlets and the air tool and set the
pressure regulator to zero pressure (turned fully anticlockwise).
4. Start the engine in accordance with the instructions contained in the
engine service manual, then close the bleed valve and allow pressure to
build up.
5. When the Air Governor/Load Genie has operated and the compressor has
gone ‘off line’, slide the outlet valve outwards fully then adjust the pressure
regulator so that the desired pressure is registered on the gauge.
6. Check for air leaks at the tool and connectors, before proceeding.

STOPPING THE COMPRESSOR
1. At the end of the day, stop the compressor in accordance with the
instructions in the engine manual, then open the drain cock.
2. Close the air outlet by sliding both valves inwards.
3. Operate the air tool trigger or operating lever etc., to ensure there is no
pressure in the air line, then disconnect airline and tool.
WARNING: DO NOT UNDER ANY CIRCUMSTANCES ATTEMPT TO REMOVE
THE AIR TOOL OR DISCONNECT THE AIR HOSE UNTIL YOU ARE SATISFIED
THAT THE PRESSURE HAS BEEN RELIEVED.
4. Finally, close the drain cock.
5. Take care not to touch the engine or pump as they remain hot for some
time after use.
