SAFETY PRECAUTIONS
Before using your compressor it is in your own interest to read and pay
attention to the following safety rules:
1. COMPRESSED AIR IS DANGEROUS - Never direct a jet of air at people or
animals.
2. Do not operate your air compressor with any guards removed.
3. Electrical or mechanical repairs should only be carried out by a qualified
electrician/engineer. If you have a problem, contact your local dealer, or our
Service Department on 020 8988 7400
4. Before attempting any repair ensure pressure is expelled from the air receiver
and disconnect from electrical supply.
5. Do not leave pressure in air receiver overnight or when transporting.
6. Do not adjust or tamper with any safety valves. The maximum working pressure
of the compressor is clearly stated on the machine.
7. Exercise caution when transporting the machine to avoid tipping the machine
over.
8. Do not operate in a wet/damp environment.
9. Locate your air compressor on a firm flat surface with AVMs and ensure an
adequate supply of clean air is available to the pump unit.
10. Do not exert any strain on electrical cables and ensure that air hoses are not
tangled or wrapped around machinery etc.
11. The cylinder head and delivery pipes of your compressor become quite hot
during operation. Do not touch. After switching off remember to leave an
adequate cool-down period before touching.
12. Ensure that any equipment/tool used in conjunction with your compressor has
a safe working pressure exceeding the output pressure of the machine.
13. When disconnecting air hoses or other equipment from your compressor
ensure that the air supply is turned off at the machine outlet and expel all
pressurised air from within the air hose and other equipment attached to it.
14. If using your compressor for paint spraying:
• Never spray close to any source of flame or heat.
• Always ensure that the spraying area has adequate fresh air ventilation.
• Hazardous paints require special apparatus (see paint manufacturers
recommendations).
15. Never let people operate the compressor unless they have had the necessary
training.
16. Permanently installed pipework systems should be designed and installed by a
competent engineer.

INSTALLATION
Before installing your machine, check that its air output is sufficient for the
equipment to be used. The air output from the compressor must be more than
the volume of air required. We recommend the following:
1. Firm and level site, and the use of floor mountings for stationary
compressors - anti-vibration pads. (Do not bolt machines directly to the
floor).
2. Dust and damp free environment.
3. Adequate ventilation for:-
• Air intake to compressor pump (in order to draw in clean air).
• Cooling to compressor pump, and electric motor.
4. To allow sufficient access for servicing, a minimum clearance of 500mm
must be allowed around the machine.
5. The power cable from the main supply must be large enough to carry the
starting and running load of the electric motor. This is particularly relevant if
the compressor is some distance from the source of supply.
6. Electrical installations should be completed by a qualified electrician.
7. Electrical connection to the mains supply must be via a suitably fused (see
table on page 6) approved plug or isolator (allowing sufficient capacity for
motor starting). If using a circuit breaker, ensure it is motor rated and of
sufficient size to allow for motor starting.
8. Compressors should be connected to mains electricity supply via an earth
leakage protection device (RCD).
WARNING: MOVE THE COMPRESSOR ON A PALLET OR USING SLINGS
BENEATH THE RECEIVER NEAR TO THE DOMED ENDS, EMPLOYING A FORK
LIFT TRUCK OR WHEELED GANTRY CRANE. BEWARE OF OFF CENTRE
LOADS. THE WEIGHT OF THE COMPRESSOR IS SHOWN ON THE DATA TABLE

BEFORE STARTING COMPRESSOR, CHECK:-
1. Compressor Pump Oil Level using (a) Dipstick (to level
marked) or (b) sight glass (see fig.1)
2. Automatic Control:- Pressure switch ON/OFF switch is in
the OFF position.
TO START COMPRESSOR
1. Switch on isolator (mains supply)
2. Switch on pressure switch (lift knob or twist switch). (See “GENERAL
ARRANGEMENT” on page 8., item 22)
3. Check rotation (Flywheel/Fan blows air over pump)
4. Run compressor for 10 minutes with outlet valves open (first time of
operation only).
5. Close valves and check that pressure does not exceed maximum working
pressure (stamped on machine plate), if the pressure exceeds the
maximum working pressure stated, stop the machine (see below), vent the
system and contact the Clarke Service Department.
TO STOP COMPRESSOR
1. Switch off at the pressure switch (Push knob down or turn switch).
2. Isolate from the Mains Supply.
3. Drain air receiver (release drain tap).
NOTE: When starting compressors up to and including the 3HP models,
an auto bleed valve will operate and air will be heard vent. This is
quite normal and should not cause concern. The valve should
close after several seconds. Should it fail to close, consult your
Clarke dealer.
WARNING:
1. BEFORE STARTING COMPRESSOR, OPEN ALL OUTLET VALVES.
2. THE FOLLOWING START AND STOP INSTRUCTIONS MUST BE
FOLLOWED IN THE CORRECT SEQUENCE TO AVOID SERIOUS
DAMAGE TO THE COMPRESSOR/MOTOR.
WARNING: COMPRESSOR PUMPS, DELIVERY PIPES WILL REMAIN HOT FOR
SOME TIME AFTER USE.

GENERAL ARRANGEMENT
NOTE: On automatic machines (10 H.P). a solenoid valve is fitted to the
delivery pipe.
NOTE: On automatic machines (10 H.P), an Auto Star Delta (ASD) starter
is fitted, ready to be mounted to a wall or panel etc. It is
IMPORTANT to note that NO ADJUSTMENTS should be made to this
component. The ASD should be connected to a 3-phase supply
by a qualified electrician.

OUTLET PRESSURE ADJUSTMENTS
PORTABLE COMPRESSORS
1. Pressure Adjusting Knob
2. Outlet Taps
3. Pressure Gauge
TO ADJUST OUTLET PRESSURE:
To increase pressure - turn knob (1)
clockwise. To decrease pressure - turn
knob (1) anticlockwise.
Outlet taps - slide knurled section (2) away
from body to open, push towards body to
close.
NOTE: Pressure Gauge (3). Pressure shown will differ by approximately 1
bar depending on whether the outlets are open/closed.
STATIONARY COMPRESSORS
These machines are not supplied with the facility to adjust outlet pressure. A
comprehensive range of airline accessories is available from your local
CLARKE stockist.
OVERLOAD BUTTON (SINGLE PHASE ONLY)
The electric motor is fitted with an automatic
overload detector which will stop the motor if an
overload is detected.
If this happens,
1. Switch off at the pressure switch (Push knob
down or turn switch).
• Allow the compressor to cool down for 5-10
minutes.
2. Press the Reset button shown on the right.
3. Switch on pressure switch (lift knob or twist switch).
If the overload trips repeatedly, it may indicate a fault with the compressor, in
this case you should contact the Clarke service department.
