Description of Operation

Become familiar with these controls before operating the unit.

Auto/On/Off Switch: Set switch

in AUTO/ON position to provide

automatic power to the pressure	Tank
switch and OFF to remove power	Pressure	Outlet
at the end of each use.	Gauge	Pressure
Pressure Switch (not shown):		Gauge
	Auto/On/Off
The pressure switch automatically
starts the motor when the air tank	Switch
pressure drops below the factory		Regulator
set "cut-in" pressure. It stops the
motor when the air tank pressure
reaches the factory set "cut-out"	Safety
pressure.
Safety Valve: If the pressure	Valve

switch does not shut off the air compressor at its "cut-out" pressure setting, the safety valve will protect against high pressure by "popping out" at its factory set pressure (slightly higher than the pressure switch "cut-out" setting). Outlet Pressure Gauge: The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure.

Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.

Regulator: Controls the air pressure shown on the outlet pressure gauge. Pull the knob out and turn clockwise to increase pressure and counterclockwise to decrease pressure. When the desired pressure is reached push knob in to lock in place.

Drain Valve: The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use.

Cooling System (not shown): This compressor contains an advanced design cooling system. At the

heart of this cooling system is an engineered fan. It is

perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled. NOTE: It is normal for the fan to run continuously when the unit is in the "ON" position. To turn the fan off, switch the unit to the "OFF" positon. Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.

Check Valve (not shown): When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank. When the air compressor reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain inside the air tank.
