Occasionally you may want to adjust the cut off pressure of your air compressor. With your SGS air compressor it couldn't be simpler to make these small adjustments.
The compressor is controlled by a pressure switch and a relief valve. The compressor 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 - don’t alter it carelessly.
To adjust the pressure remove the black cover from the pressure switch. Turn the adjusting screw anticlockwise to lower the cut off pressure and clockwise to increase the cut off pressure.
