OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
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
switch and OFF to remove power
at the end of each use.
Pressure Switch (not shown):
The pressure switch automatically
starts the motor when the air tank
pressure drops below the factory
set "cut-in" pressure. It stops the
motor when the air tank pressure
reaches the factory set "cut-out"
pressure.
Safety Valve: If the pressure
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.
