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.
These photographs are for reference only and do not represent a specific model
On/Auto/Off Switch
: Turn this switch ON
to provide automatic power to the pressure
switch and OFF to remove power at the
end of each use.
Pressure Switch:
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 pres-
sure (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 engi-
neered 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.
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 out-
let.
Check Valve:
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.
