Regulator
The air pressure coming from the air tank is controlled by the regulator. To Increase the pressure, turn the knob clockwise and to decrease the pressure turn the knob counterclockwise.
Tank Safety Valve
Used to allow excess tank pressure to escape into the atmosphere. This valve should only open when the tank pressure is above the maximum rated pressure.
Pressure Switch
This controls the power to the motor and also the cut-in/cut-out pressure settings. This switch serves as the Auto-On/Off positions for the unit.
Pressure Relief Valve
The pressure relief valve, located on the side of the pressure switch, is designed to automatically release compressed air when the air compressor reaches cut-out pressure. The released air should only escape momentarily and the valve should then close.
Pressure Relief Tube
Check Valve
When the pump is not in operation, the valve closes to retain air pressure inside the tank. An internal component.

Grounding Instructions
This product should be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock
by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. (See the figure below.)
The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. Check with a qualified electrician or service personnel if these instructions are not completely understood or if in doubt as to whether the tool is properly grounded.
A WARNING
Improper installation of the grounding plug will result in a risk of electric shock. If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without
yellow stripes is the grounding wire. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded. Do not modify the plug provided, if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
This product is for use on a circuit having a nominal rating of 120 volts and is factory-equipped with a specific electric cord and plug to permit connection to a proper electric circuit. Make sure the product is connected to an outlet having the same configuration as the plug. An adapter should not be used with this product. If the product must be reconnected for use on a different type of electric circuit, qualified service personnel should make the reconnection.
Extension Cords
Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. Cords must not exceed 25 feet and No. 12 AWG size must be used. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
