SAFETY PRECAUTIONS
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:
1. COMPRESSED AIR IS DANGEROUS, NEVER direct a jet of air at people or animals, and
NEVER discharge compressed air against the skin.
2. ALWAYS place the compressor on a flat horizontal surface.
3. Electrical or mechanical repairs should only be carried out by a qualified engineer. If
problems occur, contact your Clarke dealer.
4. Before carrying out any maintenance, ensure the pressure is expelled from the air
receiver, and the machine is disconnected from the mains supply.
5. DO NOT leave pressure in the receiver overnight, or when transporting.
6. DO NOT adjust, or tamper with the safety valves. The maximum pressure is factory set,
and clearly marked on the machine.
7. DO NOT 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.
8. Some of the metal parts can become quite hot during operation. Take care not to
touch these until the machine has cooled down.
9. Always adjust the pressure regulator to the recommended setting for the particular
spray gun or tool being used.
10. When spraying flammable materials e.g. cellulose paint, ensure that there is adequate
ventilation and keep clear of any possible source of ignition.
11. 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.
12. Before spraying any material always consult paint manufacturers instructions for safety
and usage.
13. Do not exert any strain on electrical cables and ensure that air hoses are not angled or
wrapped around machinery etc.
14. 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 machine and other equipment attached to it.
15. Make sure that children and animals are kept well away from the compressor and any
equipment attached to it.
16. Always ensure that all individuals using the compressor have read and fully understand
these Operating Instructions.
17. Ensure that any equipment or tool used in conjunction with your compressor, has a
safety working pressure exceeding that of the machine.

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through
an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.
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 lead 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-rewireable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted into a socket outlet.
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.
FUSE RATING
The fuse in the plug must be replaced with one of the same rating (13 amps) and
this replacement must be approved to BS1362.
We recommend that this machine is connected to the mains supply via a Residual
Current Device (RCD)
If in any doubt, DO NOT attempt any connections or repairs yourself. Consult a
qualified electrician, your Clarke dealer,
or telephone CLARKE International Service Dept. on: 020 8556 4443
or, e-mail : [email protected]

OPERATION
Fig.1
Firstly, ensure the compressor is on level ground...do not allow it
to run if it is standing on an incline.
Check also that the mains voltage corresponds with that
shown on the data label on the side of the compressor.
Ensure that the ON/OFF switch, mounted on the Pressure
Regulator (shown in fig. 3), is turned to the ‘0’ (OFF) position,
then plug in and switch ON at the mains supply.
1. To start the compressor, turn the ON/OFF switch to the
‘I’ (ON) position - the motor should start immediately.
NOTE: Should the motor fail to start immediately, it is possible
that the air receiver is already full of air. Check the tank
pressure gauge (see fig. 4). If you release air, by opening
the air drain valve (see fig. 1), the motor will start
automatically once the cut-in pressure is reached.

Fig.3
PREPARATION FOR USE
The compressor MUST be filled with oil before use.
A 500mL bottle of Synthetic Oil is provided.
Remove the travel plug, fitted to the Oil Filler/
Breather, and fill with oil using the funnel provided,
so that the level is midway across the Oil Sight Glass
(indicated in Fig.1).
When satisfied, place the breather, contained in
the bag of loose parts, firmly on to the Filler/Breather
spout.

IMPORTANT:
Always refer to the accessory manufacturers recommendations for
optimum operating pressures for their equipment.
4. With the operating pressure set, reopen the air outlet tap.
5. The Pressure Switch, located within the plastic cover beneath the ON/OFF switch,
should not require adjustment. This is an automatic device and has been preset at
the factory to stop the motor when pressure in the receiver reaches its maximum,
and to start it again when the pressure in the receiver falls to the minimum preset
value. This operation is completely automatic and does not affect the spraying
process in any way. However, should problems develop with the cut-in, cut out
settings, please consult your Clarke dealer, or the Clarke Service Dept..
NOTE:
a . If the machine pumps continuously without cutting out then the compressor is too
small for the application/tool being used, and damage may result. Consult your
Clarke dealer.
b. The motor is protected by a Thermal Overload so that if the motor overheats for any
reason - the thermal overload will trip, stopping the motor. Allow a period for the
motor to cool down before restarting (15 - 20 minutes).
c. DO NOT exceed the Duty Cycle for the machine (see Specifications).
NOTE: For most spray work do not exceed 50 psi (unless following paint manufacturer’s
instructions).
For other airline equipment such as, tyre gauges, staple guns, paraffin guns etc., it may be
necessary to set the operating pressure at a higher (or lower) level.
Before connecting your airline to the compressor,
allow it to run for 10 - 15 seconds, with the air drain
Valve, (see, Fig. 1) completely open to permit a good
distribution of the lubricating oil.
2. Close the outlet tap then connect one end of suitable
air hose to the outlet connector (see Fig. 1) , and the
other end to the equipment to be used.
3. Set the outlet pressure by adjusting the Pressure
Regulator.
To do this, lift the Pressure Regulator Knob, and turn it
clockwise to increase pressure, anticlockwise to
decrease as noted on the Outlet Gauge.
To lock the Regulator Knob and hence the outlet
pressure, push the Regulator Knob down until it clicks
into place.
Fig.4

IMPORTANT:
ALWAYS switch the compressor ON or OFF at the Pressure Switch...NEVER at the mains
supply switch
Fig.5
SHUTTING DOWN THE COMPRESSOR
1. To shut down the compressor, simply turn the ON/OFF switch to the ‘O’ (OFF) position.
MAINTENANCE
DAILY
1. Check the oil level before you start and top up if necessary - use Synthetic
Air Compressor Oil ONLY, available from your Clarke dealer..Part No. 3050795
The oil level is checked by viewing the oil sight glass, see Fig. 1.
To add oil, proceed as follows:
Remove the air breather (see Fig.7), and top up
until the oil level is midway on the oil sight glass.
2. Drain any condensate that may have
accumulated in the air outlet filter, by pushing
the valve (arrowed in Fig. 6), upwards, with
the tank under pressure.
3. When you have finished with the compressor,
ALWAYS open the drain valve to expel all air,
and to allow any condensate to drain off.
DO NOT FORGET to close the valve again
when the tank is empty.
NOTE: In order to drain condensate by opening
the drain valve, the tank MUST be under pressure.
Fig.6
2. Close the air outlet tap and trigger the equipment (spray
gun,air tool etc.) to release air from the air hose before
disconnecting the hose from the machine.
3. Before transporting your compressor or when leaving
overnight, expel all air from the receiver by opening the
drain valve - Fig 5.

PERIODICALLY
1. Renew Air Breather every 500 hours of
operation.
2. Drain and replace the oil annually, as
follows:
(I) Slacken off the screw securing the
Compressor Head Securing Collar, shown
in Fig. 8, and remove the collar.
(iii) Pull off the Head, complete with
sealing ring.
(iii) Tilt the compressor carefully on to its side,
as shown in fig. 8, so that the oil may be
drained into a suitable container.
Dispose of the oil according to local
ordinances.
(iv) Reassemble the head ensuring the
sealing ring is in perfect condition and is
located correctly.
IMPORTANT! USE ONLY SYNTHETIC OIL,
available from your CLARKE dealer.
Fig.8
3. Check the time it takes to fill the air tank,
periodically, as follows:
(i) Ensure the tank is fully drained and the drain tap and outlet tap firmly closed.
(ii) Start compressor and check to ensure there are no leaks, using soapy
water on all joints. Should any leak be apparent, stop the compressor,
drain the tank and rectify the leak before proceeding.
(iii) The time taken to charge the tank is 220 seconds at 20 degrees C, ± 5%
(iv) Check to ensure the cut-out pressure is 8bar (120psi), if not, consult your
Clarke dealer.
Should the tank charging time be excessive, and no leaks are apparent,
consult your Clarke dealer.
4. Check the Air Filter Should the air filter
become dirty, consult your Clarke dealer.
5. Check the Non-Return Valve
Should the tank pressure decrease for no
apparent reason, it is possible that the non-
return valve is leaking. To check, ensure the tank
is under pressure and the machine switched
OFF, then disconnect the flexible pipe (A Fig 9)
from the compressor head to the pressure valve
If air is found to be leaking, empty the tank then
dismantle the non-return valve as follows:
