OPERATION & ADJUSTMENT

5

1. The compressor is controlled by a pressure switch. It can be
    stopped automatically as the pressure increases to the maximum
    and restarted as pressure decreases to the minimum. The rated
    pressure has been adjusted during the manufacturing process -
    do not alter it carelessly.
2. As soon as the motor is switched off the compressed air in the
    discharge pipe should be released through the release valve
    under the switch. This is a necessary condition before restarting
    or the motor will be damaged.
3. The output pressure of compressed air can be regulated by using the 
    regulating valve. turn the regulation valve knob clockwise to
    increase the pressure.
4. When the compressor needs to be stopped, set the power switch to 
    the ‘OFF’ position.
5.  If the compressor should overheat, the Thermal Overload will 
     intervene and shut down the compressor. Should this happen, switch 
     OFF the machine by pushing the STOP/START switch downwards, and 
     wait for at least 5 minutes before pressing the red RESET button 
     underneath the air filter and try to start the compressor again.
