Pressure Regulator
The pressure gauge will indicate the amount of pressure that will be delivered from the tank. To adjust the delivery pressure, 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. Turn the pressure adjustment screw (See Figure 4) clockwise to decrease pressure and counterclockwise to increase pressure. Replace the cover when the adjustment is complete.

Always wear safety glasses and use extreme caution when working around compressed air. The force of the air stream can cause small bits of debris to become airborne and cause potential injury to the eyes or other parts of the body. Never let the full force of the air stream come in direct contact with the skin as it can cause abrasions or bruising.
