Pressure Switch
The pressure switch has been factory set for the highest PSI that is safe for this compressor.
The pressure switch ensures the pump will shut OFF when the air compressor tank reaches maximum PSI.
NOTICE
This air compressor has been factory set to turn ON and OFF at the proper PSI range. Only attempt to adjust the pressure regulator if your air com- pressor does not reach, or pressur- izes beyond the proper PSI level.
To adjust the pressure switch:
1.Unplug the air compressor from the power supply.
2.Make sure the compressor switch is in the OFF position.
3.Drain the pressure from the tank.
4.Remove the black AUTO/OFF switch cover (Figure 15) by removing the screw in the recess of the cover. Pull the black cover up and set it aside.
Figure 15. Pressure switch cover.
5.Turn the black plastic pressure adjust- ment screw (Figure 16) a half turn clockwise to increase the tank pressure and a half turn counterclockwise to decrease the pressure.
Figure 16. Pressure adjustment screws.
6.Adjust the metal pressure adjustment screw to change how low the pressure can drop before the motor turns ON.
7.Connect the compressor to the power supply and start the compressor. If the compressor does not automati- cally turn OFF at 120 PSI, flip the ON/ OFF switch to OFF before the pres- sure reaches 125 PSI.
8.If the PSI level still needs adjustment, repeat Steps
9.Replace the cover when the proper adjustments have been completed.
