GLOSSARY
Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per
minute; a unit of measure of air delivery.
PSIG: Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by OSHA certified
independent safety laboratories and
meet the applicable Underwriters
Laboratories Standards for Safety.
Cut-In Pressure: While the motor is
off, air tank pressure drops as you
continue to use your accessory.
When the tank pressure drops to a
certain low level the motor will restart
automatically. The low pressure at
which the motor automatically
restarts is called “cut-in” pressure.
Cut-Out Pressure: When an air
compressor is turned on and begins
to run, air pressure in the air tank
begins to build. It builds to a certain
high pressure before the motor automatically shuts off - protecting your
air tank from pressure higher than its
capacity. The high pressure at which
the motor shuts off is called “cut-out”
pressure.
Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
To Lock Out Power: Place a lock on
the line power switch so no one else
can turn on the power.
DUTY CYCLE
Air compressors should be operated
on not more than a 50% duty cycle.
This means an air compressor that
pumps air more than 50% of one
hour is considered misuse, because
the air compressor is undersized for
the required air demand. Maximum
compressor pumping time per hour is
30 minutes.

To Add Oil To Pump
Compressors are
shipped without oil.
A small amount of oil may be present in the pump upon receipt of the
air compressor. This is due to plant
testing and does not mean the
pump contains oil. Do not attempt
to operate this air compressor
without first adding oil to the
crankcase. Serious damage can
result from even limited operation
unless filled with oil and broken in
correctly. Make sure to closely follow initial start-up procedures.
Multi-Viscosity
motor oils, like
10W 30, should not be used in an
air compressor. They leave carbon
deposits on critical components,
thus reducing performance and
compressor life. Use air compressor oil only.

Wiring Instructions
Air Distribution System
RISK OF ELECTRICAL SHOCK.
Improper electrical grounding can
result in electrical shock. The
wiring should be done by a qualified electrician to comply with
national and local electrical codes.
A qualified electrician needs to knows
the following before wiring:
1. The amperage rating of the electrical box should be adequate.
Refer to the product specifications, found in the front of this
manual, for this information.
2. The supply line should have the
same electrical characteristics
(voltage, cycle, phase) as the
motor. Refer to the motor nameplate, on side of motor, for this
information.
NOTE: The wiring must be the same
as the motor nameplate voltage plus
or minus 10%. Refer to local codes
for recommended wire sizes, correct
wire size, and maximum wire run;
undersize wire causes high amp draw
and overheating to the motor.
Electrical wiring
must be located
away from hot surfaces such as
manifold assembly, compressor
outlet tubes, heads, or cylinders.
Plastic or PVC pipe
is not designed for
use with compressed air.
Regardless of its indicated pressure rating, plastic pipe can burst
from air pressure. Use only metal
pipe for air distribution lines.
The next figure represents a typical
air distribution system. The following
are tips to remember when setting up
the air compressor’s air distribution
system.
GROUNDING INSTRUCTIONS
•
Use pipe that is the same size as
the air tank outlet. Piping that is
too small will restrict the flow of
air.
•
If piping is over 100 feet long,
use the next larger size.
•
Bury underground lines below
the frost line and avoid pockets
where condensation can gather
and freeze. Fill lines with air pressure before covering to make
sure pipe joints are free from
leaks.
•
Install a flexible coupling
between the air discharge outlet
and main air distribution line to
allow for vibration.
NOTE: The shut-off valve is not supplied with this unit. You must purchsase the shut-off valve separately.
•
This product should be connected to
a metallic, permanent wiring system,
or an equipment-grounding terminal
or lead on the product and comply
with national and local electrical
codes.
Refer to the product specification
found in the front of this manual for
the voltage and minimum branch circuit requirements.

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.
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.
On/Auto/Off
Switch
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.
Pressure
Switch
Tank
Pressure
Gauge
Safety Valve: If the pressure switch
Safety Valve
Globe Valve
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 pressure gauge indicates the reserve air
pressure in the tank.
Globe Valve (sold separately): 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 combines the functions of air regulation and/or moisture and dirt removal is recommended for most applications.
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
Drain
contains an advanced design cooling system. At
Valve
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.
13-ENG
D26161
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
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.
Pressure
Release
Valve
Pressure Release Valve: The pressure 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 motor stops running, air will be heard escaping from
this valve for a few seconds. No air should be heard leaking when the motor is
running, or continuous leaking after unit reaches “cut-out” pressure.
Air Intake Filter (not shown) This filter is designed to clean air coming into
the pump. This filter must always be clean and ventilation openings free from
obstructions. See “Maintenance”.
How to Use Your Unit
How to Stop:
