3.6.
To ensure good ventilation and efficient cooling, the compressor's
belt guard must be at least 100cm from any wall (fig.3).
Compressors with fixed feet, should not be rigidly secured to
the floor. In this case, it is advised to fit 4 anti-vibration supports
(optional extra).
3.7.
take care to transport the compressor correctly, do not overturn
it or lift it with hooks or ropes.
3.8.
remove the plastic transit plug from the oil filler hole (fig.4) and
replace it with the filler/breather plug. It is a push fit, ensure that it
is pushed fully home.
3.9.
Before using the compressor, check the oil level by observing the
sight glass as shown in fig.4. If the oil is not up to the max mark
it should be topped up with synthetic oil suitable for temperatures
ranging from -5°c to 45°c (viscosity 5W50). We do not
recommend using mineral oil in these compressors. do not
overfill.

4. OPERATION
WARNING! Ensure that you have read, understood and
apply Section 1 safety instructions.
IMPORTANT! The use of extension leads to connect these
compressors to the mains is not recommended as the
resulting voltage drop reduces motor, and therefore pump
performance, and could cause damage to the compressor.
NOTE: take care when selecting tools for use with the
compressor. Air tool manufacturers normally express the
volume of air required to operate a tool in cubic feet per minute
(cfm). this refers to free air delivered by the compressor ('air
out') which varies according to the pressure setting. do not
confuse this with the compressor displacement which is the air
taken in by the compressor ('air in'). 'Air out' is always less than
'air in' due to losses within the compressor.
4.1.
STARTING THE COMPRESSOR
to turn the compressor on use the switch on the top of
the pressure switch housing (figs.6.1 and 7.1). turn the
switch clockwise to position 'I' to start the compressor and
anti-clockwise to position 'o' to stop it.
4.2.
check that the on/off switch is in the 'o' position. on
Models sAc1503B and sAc1103B the regulator tap (fig.6.2)
should be closed and the output gauge (fig.6.4) must read Zero
'0' bar.
4.3.
Plug into mains supply and start the compressor by turning the
switch to the 'I' position.
4.4.
When starting the compressor for the first time, leave it running
with no air tools connected to the air outlet. Make sure that
pressure in the tank rises and that the compressor stops
automatically when the maximum pressure value allowed -
written on the plate and shown on the gauge (figs.6.5 & 7.5) -
is achieved. the compressor will now operate automatically.
the pressure switch stops the motor when the maximum tank
pressure is reached and restarts it when the pressure falls
below the minimum threshold - approx. 2 bar (29psi) less than
the maximum pressure.
4.5.
stop the compressor by turning the main switch to the 'o'
position. the compressed air inside the compressor head will
flow out, making the restart easier and preventing the motor from
being damaged. DO NOT, other than in an emergency, stop the
compressor by switching off the mains socket, or by pulling the
plug out, as the pressure relief will not then operate and motor
damage may result upon restart.
4.6.
the motor of the compressor is fitted with a thermal breaker
located in the housing on top of the motor. the manual resetting
button is located in the end of the housing as shown in fig.10A.
When the breaker is tripped, wait for a few minutes and then
press the reset button.
4.7.
on Models sAc1503B and sAc1103B, the output pressure is
regulated by the pressure regulator (fig.6.2). turn the knob
clockwise to increase pressure and anti-clockwise to reduce it.
lock knob in position at required pressure with locking ring. to
determine the correct working pressure for any piece of
equipment check the corresponding manual. When the
compressor is not being used, set the regulated pressure to zero
so as to avoid damaging the pressure regulator.
NOTE: a) If the motor does not cut in and out, but runs
continuously when using an air appliance, the capacity of the
compressor may be too small for the equipment or tool.
b) the gauge (figs.6.5 and 7.5) indicates the pressure inside the
main tank, not the pressure supplied to the air equipment.
should the pressure in the main tank exceed the pre-set switch
maximum, the safety valve will activate.
WARNING! For this reason DO NOT tamper with, or adjust,
the switch or safety valve.

5. MAINTENANCE
In order to keep the compressor in good working condition,
periodic maintenance is essential.
IMPORTANT! Failure to carry out maintenance tasks may
invalidate the warranty on your compressor.
