4.6.
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).
4.7.
Take care to transport the compressor correctly,
DO NOT
overturn it or lift it with hooks or ropes.
4.8.
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.
4.9.
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.
5. OPERATION
WARNING!
Ensure that you have read, understood and apply Section 1
safety instructions.
IMPORTANT!
Use of extension leads to connect these compressors to the
the mains is not recommended as the resulting voltage drop reduces motor
and therefore pump performance, and could damage 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.
5.1.
STARTING / STOPPING THE COMPRESSOR
5.1.1.
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.
5.1.2.
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.
5.1.3.
Plug into mains supply and start the compressor by turning the switch to the
‘I’ position.
5.1.4.
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.
5.1.5.
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
