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 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 
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(g.5).Lifttheswitchuptostartthe
compressor and push in to stop it.
5.1.2. CheckthattheON/OFFswitchisintheOnposition.On 
 ModelsSAC15030BandSAC20030Btheregulatortap(g.5)shouldbeclosedandtheoutputgauge(g.5)mustreadZero‘0’bar.
5.1.3. Plug into mains supply and startthecompressorbyliftinguptheOn/Off.

the tank rises and that the compressor stops automatically when the maximum pressure value allowed - written on the plate and shown
on the gauge (fig.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pushingintheOn/Offswitch.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.
5.1.6. 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.6. When the breaker is tripped, wait for a few minutes and then press the reset button.
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 (fig.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.
6. MAINTENANCE
6.1. 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.
WARNING!Beforeperforminganymaintenanceoperation,switcho󰀨thecompressor,disconnectfromelectricitysupplyandreleaseall
