Original Language Version  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 which may cause damage to your 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 check that the off switch (fig.4) is pushed in (the off position). to turn the compressor on, plug mains lead into mains supply, press the "on" button on the front panel (fig.4). 4.2. 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 in fig.4) 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. 2bar (29psi) less than the maximum pressure. 4.3. stop the compressor by pressing the off switch in (fig.4). 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 power, or by pulling the plug out, as the pressure relief will not then operate and motor damage may result upon restart. When the compressor runs correctly and is stopped correctly there will be: (a) a whistle of compressed air when the motor stops. (b) a protracted whistle (about 20-25 seconds) when the compressor starts with no pressure in the tank. NOtE: 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. the gauge (fig.4) 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, a safety valve will activate. WaRNiNg! for this reason dO NOT tamper with, or adjust, the switch or safety valve. 4. OPERatiON fig.1 fig.4 fig.2 fig.3 fig.5
