Should the motor fail to start immediately, it is probable that the air receiver is
already full of air. Check the tank pressure gauge (F). If you release air, by opening
air outlet tap (I), the motor will start automatically once the cut-in pressure is
reached.
If this is not the case, it is possible that the overload cutout has intervened. This is a
safety device to prevent the motor from overheating. In this event, switch OFF the
machine and wait for 10 - 15 minutes, depending upon ambient temperature,
before pressing the reset button and attempting to restart. If the motor fails to
start, after several attempts, consult your Clarke dealer.
Once the machine has started, turn ON the air supply to your air tool by opening
the tap (I), and turn the pressure regulator (C) clockwise so that your chosen
setting, is shown on the air outlet pressure gauge.
Check to ensure that there are no air leaks at any of the couplings or in other
parts of the system before operating the spray gun or air tool in the normal way. If
any leaks are apparent, switch OFF the machine by pushing the ON/OFF knob
downwards, and rectify before proceeding.
When the compressor reaches its maximum working pressure, the motor will
automatically cut out, and will restart when the pressure has fallen by approximately
20 psi. This automatic STOP/START process will continue, as necessary, to maintain
pressure in the receiver.
When you have finished the job in hand
ALWAYS
switch OFF at the ON/OFF switch,
NOT the mains supply, and release any pressure remaining in the system by opening
the drain valve until all air is expelled. This also allows any condensate to drain off.
ALWAYS
operate the air tool to further ensure that there is no pressure in the system
BEFORE
disconnecting the tool. Finally, reset the pressure regulator to zero by turning
the knob fully anticlockwise.
Thermal Overload
A thermal overload prevents the motor from overheating
if used for prolonged periods. If the overload operates,
switch OFF the machine and allow it to cool for at least 5
minutes before pressing the RESET button located beneath
the left hand side of the cowl - see Fig.5, and attempting
to restart. If the machine refuses to start after several
attempts, consult your Clarke dealer.
Fig. 5
The air compressor will now start, and pressure will build up in the receiver to a
regulated max. pressure of 8 Bar (115 psi).

MONTHLY
Start the compressor, and pressurise the system. Inspect all
joints for leaks using soapy water, and rectify as necessary.

ROUTINE MAINTENANCE
IMPORTANT! Before carrying out any service work, ALWAYS disconnect the compressor
from the mains supply and release any air in the receiver. If necessary allow the
machine to cool down before proceeding.
It is most important to keep the Air Compressor clean, this can be carried out using a small
soft brush and a vacuum cleaner. In particular the air filter should be inspected periodically,
so that it is always kept clean. If this instruction is not adhered to, a loss of performance
could occur, even worse, any dirt passing through the filter could make its way into the
cylinder head and adversely affect the valves. This could lead to more extensive damage
necessitating its dismantling and replacement parts etc.
BEFORE EACH USE
Drain any condensate which may be present in the receiver, Undo the drain cock and tilt
the machine so that the drain valve is at the lowest point in order to do so.
WEEKLY
1.
Unclip the air filter cover, which has a bayonet fitting, then
remove the filter and blow away any loose dirt. If
damaged or badly contaminated, it must be replaced.
2.
Clean the fins of the compressor cylinder and the
cylinder head to receiver pipe. A clean compressor
will work more efficiently.
3.
With the machine on a flat level surface, check he oil
level, It should be in the centre of the oil sight glass, at
the red spot (Fig.3). If necessary, top up with SAE40 non
detergent oil, by unscrewing the breather and using a
small funnel to top up. Unscrew the breather cap and
check to ensure the filter is clean (Fig.4) and breather
hole is clear before screwing back in place.
4.
Check to ensure all nuts and bolts are tight. Check
cylinder head bolts which should be tightened to
13.6 Nm (10lbf ft).
(Whichever occurs first)
Change the compressor oil. Drain oil by removing the
breather and turning the compressor on to its end.
Support it in this position and leave for a period to ensure
all oil is drained.
Caution
Do not attempt any repairs or adjustments if you are
uncertain as how it should be done. Contact your
nearest CLARKE dealer, or phone CLARKE
