6. Close the drain valve (Figure 5) to
allow the tank to build up pressure.
7. Check the tank pressure gauge (Figure
6) to see that the tank pressure climbs
to approximately 115-120 PSI (around
8 BAR), then automatically turns
OFF.
Note: If the compressor does not auto-
matically turn
OFF at 120 PSI (115
PSI for the Model G0468), flip the ON/
OFF switch to OFF before the pres-
sure reaches the maximum PSI shown
on
Page 3. See Pressure Switch on
Page 21 to adjust the automatic shut-

Figure 7. Tool air control knob.
The tank pressure is displayed on the left
pressure gauge, and the air to be deliv-
ered to the tool (line pressure) is displayed
on the right pressure gauge, shown in
Figure 6.
The air tool that you attach to the air
compressor should have a preferred PSI
operating level. Set the pressure to be
delivered to the tool according to the
required level of the tool.
To control the air supply to your tool:
1. Adjust the air control knob, shown in
Figure 7, to set the PSI that will be
delivered to your tool. Turn the knob
clockwise to increase the pressure or
counterclockwise to decrease the pres-
sure.
