Operating Instructions

Introduction
Refer to Figure 5 to locate the following
items.
Pressure Switch - Auto/Off Switch - In
the "AUTO" position, the compressor
shuts off automatically when tank
pressure reaches the maximum preset
pressure. In the "OFF" position, the
compressor will not operate. This switch
should be in the "OFF" position when
connecting or disconnecting the power
cord from the electrical outlet.
Regulator - The regulator controls
the amount of air pressure at the hose
outlet.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Exhaust Tube - This tube carries
compressed air from the pump to the
check valve. This tube becomes very hot
during use. To avoid the risk of severe
burns, never touch the discharge tube.
Check Valve - One-way valve that
allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.
Handle - Designed to move the
compressor.
Never use the
handle on wheeled
units to lift the unit completely off the
ground.
Drain Valve - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily to
reduce the risk of corrosion.
Pressure Gauges - These gauges will
show air pressure in the compressor
tank and at the compressor outlet.
Outlet Pressure Gauge - Will show
air pressure at the outlet in pounds per
square inch (psi). Make sure this gauge
reads ZERO (by adjusting regulator
knob fully counterclockwise) before
changing air tools or disconnecting air
hose from outlet.
Tank Pressure Gauge - Will show air
pressure in tank while the compressor
is running, indicating compressor
is building pressure properly. This
gauge will show maximum pressure
of compressor when it shuts off
automatically at the pressure switch.
Motor Reset - (not shown, located
inside motor). Designed to keep the
motor from overheating. The motor has
an auto reset protector. To reset once
the motor has cooled, turn the pressure
switch to the OFF position, then to the
AUTO position.
This compressor is
equipped with an
overload protector which will shut off
motor if it becomes overloaded.
If the overload
protector is
actuated, the motor must be allowed to
cool down for approximately 30 minutes
before it will reset.
