OPERATION
DESCRIPTION OF OPERATION
Become familiar with these controls
before operating the unit.
On/Auto(I)/Off(O) Switch: Turn this
switch "On/Auto(I)" to provide auto-
matic power to the pressure switch and
"Off(O)" 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" pres-
sure.
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).
Tank Pressure Gauge: The tank pres-
sure gauge indicates the reserve air
pressure in the tank.
Globe Valve: Opens and closes air
discharge valve. Turn knob counter-
clockwise to open and clockwise to
close.
Regulator (sold separately, not
shown): An air pressure regulator or a
separate air transformer which com-
bines the functions of air regulation
and/or moisture and dirt removal is rec-
ommended for most applications.
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.
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.
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.

reaches "cut-out" pressure, the check
valve "closes", allowing air pressure to
remain inside the air tank.
Check Valve
Pressure Release Valve: The pres-
sure release valve located on the side
of the pressure switch, is designed to
automatically release compressed air
from the compressor head and the
outlet tube when the air compressor
reaches "cut-out" pressure or is shut
off. The pressure release valve allows
the motor to restart freely. When the

Risk of unsafe operation. Unit cycles automatically when
power is on. When performing maintenance, you may be exposed to voltage
sources, compressed air, or moving parts. Personal injuries can occur. Before
performing any maintenance or repair, disconnect power source from the
compressor and bleed off all air pressure.
To ensure efficient operation and longer life of the air compressor outfit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an outfit in a normal working environment
operating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor outfits in
an extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
NOTE: See Operation section for the location of controls.

Risk of property dam-
age. Drain water from air tank may
contain oil and rust which can cause
stains.
7. After the water has been drained,
close the drain valve. The air com-
pressor can now be stored.
NOTE: If drain valve is plugged, release
all air pressure. The valve can then be
removed, cleaned, then reinstalled.
OIL
Use air compressor oil
only. Multi-weight automotive engine
oils like 10W30 should not be use in
air compressors. They leave carbon
deposits on critical components, thus
reducing performance and compres-
sor life.
NOTE: Use 40W compressor oil or a
heavy duty SAE 40W, nondetergent,
SF grade or better oil DO NOT use
multi-wieght automotive engine oils,
they will reduce compressor life. Under
exteme winter condition use SAE-20
weight oil.
NOTE: NOTE: Crankcase oil capac-
ity is approximately 40 fluid ounces
(1.2 L).

TO CHECK SAFETY VALVE
Risk of bursting. If the
safety valve does not work properly,
over-pressurization may occur, caus-
ing air tank rupture or an explosion.
Risk from Flying
Objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection
(CAN/CSA Z94.3) with side shields.
1. Before starting compressor, pull
the ring on the safety valve to make
sure that the safety valve operates
freely. If the valve is stuck or does
not operate smoothly, it must be
replaced with the same type of
valve.
TO DRAIN TANK
Risk of unsafe
operation. Air tanks contain high
pressure air. Keep face and other
body parts away from outlet of drain.
Use eye protection [ANSI Z87.1 (CAN/
CSA Z94.3)] when draining as debris
can be kicked up into face.
Risk from noise. Use
ear protection (ANSI S12.6 (S3.19) as
air flow noise is loud when draining.
NOTE: All compressed air systems gen-
erate condensate that accumulates in any
drain point (e.g., tanks, filter, aftercoolers,
dryers). This condensate contains lubri-
cating oil and/or substances which may
be regulated and must be disposed of in
accordance with local, state, and federal
laws and regulations.
1. Set the On/Auto/Off lever to "Off".
2. Close the globe valve.
3. Remove the air tool or accessory.
4. Open the globe valve and allow the
air to slowly bleed from the air tank
until tank pressure is approximately
20 psi.
5. Close the globe valve.
6. Drain water from air tank by open-
ing drain valve on bottom of tank.
Risk of bursting.
Water will condense in the air tank.
If not drained, water will corrode and
weaken the air tank causing a risk of
air tank rupture.
