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. The device will reset when
the temperature falls to a predetermined level. In this event, switch OFF the
machine and wait for 5 - 10 minutes, before pressing the RESET button (2).
Switch ON the machine and try again. If the motor fails to start, after several
attempts, consult Machine Mart.
Once the machine has started, turn ON the air supply to your air tool by opening the tap
(6), and turn the pressure regulator (5) clockwise so that your chosen setting, shown on
the label on top of the regulator knob, is opposite the inverted vee mark on the side of
the casting. Note that the pressure gauge registers the pressure in the air receiver only.
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.
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.
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.

ROUTINE MAINTENANCE
IMPORTANT: Before carrying out any of this service work, always disconnect the
machine from the mains supply, drain the air receiver and, if necessary, allow the
machine to cool down before starting work.
Daily
Before use, always open the drain valve to ensure that any condensate, which
may have accumulated, is drained off.
Monthly
It is important to keep the Compressor clean, with the help of a small soft brush
and vacuum cleaner. In particular, the air intake filter should be inspected at
least
MONTHLY
, and more often in dusty conditions, so that it is always kept free of
any dirt particles, which if not cleaned away, will
affect the performance of the machine.
To clean the air intake filter, carefully prise out the
sponge element shown in fig.2. Clean the sponge
and the inner housing using a soft brush.
If necessary, the sponge filter may be gently washed
in warm soapy water, rinsed and allowed to dry
thoroughly before refitting.

TROUBLE SHOOTING
With considerate use, your AIRMASTER Air Compressor should provide
you with long and trouble free service. Routine checks should be made
on both the electrical supply as well as on all the compressed air lines
and connections. If any fault appears, the reason for which is not
immediately obvious, we recommend that you contact Machine Mart.
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
Machine Mart.
