Tank Pressure
Regulator
The pressure regulator has been factory set for the highest quality operating perfor- mance.
The pressure regulator ensures the pump will shut off when the correct PSI is reached for the air compressor tank.
NOTICE
The Model H4517/H4518 Air Compressors have been factory set to kick off at the proper PSI range. Only attempt to adjust the pressure regulator if your air compressor does not reach or pressurizes beyond the proper PSI level.
To adjust the pressure regulator:
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 ON/OFF switch cover by removing the screw which is in the recess on the top of the cover. Pull the black cover up and set it aside.
5.Turn the pressure adjustment screw (Figure 9) a half turn clockwise to increase the tank pressure and a half turn
6.Connect the compressor to the power supply and start compressor.
7. If the PSI level still needs adjustment, repeat steps 1 through 6.
8.Replace the cover when the proper adjustments have been made.
