GLOSSARY
DUTY CYCLE
Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per min-
ute; 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 auto-
matically. 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 auto-
matically 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 elec-
tricity 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.
This air compressor pump is capable
of running continuously. However, to
prolong the life of your air compressor,
it is recommended that a 50%-75%
average duty cycle be maintained; that
is, the air compressor pump should
not run more than 30-45 minutes in
any given hour.

Wiring Instructions
Risk of Electrical
Shock. Improper
electrical grounding can result in
electrical shock. The wiring should
be done by a qualified electrician
A qualified electrician needs to knows
the following before wiring:
1. The amperage rating of the electri-
cal box should be adequate. Refer
to the Specification Chart for this
information.
2. The supply line should have the
same electrical characteristics
(voltage, cycle, phase) as the
motor. Refer to the motor name-
plate, 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 over-
heating to the motor.
Risk of Electrical
Shock. Electrical
wiring must be located away from
hot surfaces such as manifold
assembly, compressor outlet tubes,
heads, or cylinders.
GROUNDING INSTRUCTIONS
This product should be connected to
a metallic, permanent wiring system,
of an equipment-grounding terminal
or lead on the product.
Voltage and Circuit Protection
Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
Air Distribution System
Risk of Bursting.
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.
•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 (30.5 m)
long, use the next larger size.
•Bury underground lines below
the frost line and avoid pockets
where condensation can gather
and freeze. Apply pressure before
underground lines are covered to
make sure all pipe joints are free
of leaks.
•A flexible coupling is recommend-
ed to be installed between the air
discharge outlet and main air dis-
tribution line to allow for vibration.
•A separate regulator is recom-
mended to control the air pres-
sure. Air pressure from the tank
is usually to high for individual air
driven tools.

DESCRIPTION OF OPERATION
Become familiar with these controls
before operating the unit.
On/Auto/Off Lever: Turn this switch
"On/Auto" 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" 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 fac-
tory 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: Opens and closes air
discharge valve. Turn knob counter-
clockwise to open and clockwise to
close.

Check Valve: When the air compres-
sor is operating, the check valve is
"open", allowing compressed air to
enter the air tank. When the air com-
pressor reaches "cut-out" pressure,
the check valve "closes", allowing air
pressure to remain inside the air tank.

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
motor stops running, air will be heard
escaping from this valve for a few sec-
onds. No air should be heard leaking
when the motor is running or after the
unit reaches "cut-out" pressure.

Risk of Unsafe
Operation. Unit
cycles automatically when power
is on. When servicing, you may
be exposed to voltage sources,
compressed air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to
the air compressor, bleed tank
of pressure, and allow the air
compressor to cool.
To ensure efficient operation and lon-
ger life of the air compressor, a routine
maintenance schedule should be pre-
pared and followed. The above routine
maintenance schedule is geared to an
air compressor in a normal working
environment operating on a daily basis.
If necessary, the schedule should be
modified to suit the conditions under
which your air compressor is used.
The modifications will depend upon
the hours of operation and the work-
ing environment. Compressors in an
extremely dirty and/or hostile environ-
ment will require a greater frequency of
all maintenance checks.
NOTE: See Operation section for the
location of controls.
TO CHECK SAFETY VALVE
Risk of Bursting.
If the safety valve
does not work properly, over-
pressurization may occur, causing
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. Risk
from noise. Air tanks contain high
pressure air. Keep face and other
body parts away from outlet of
drain. Use ANSI Z87.1 eye protection
(CAN/CSA Z94.3) when draining as
debris can be kicked up into face.
Use ear protection (
ANSI S12.6
(S3.19) hearing protection)
as air flow
noise is loud when draining.
NOTE: Operation of the air compres-
sor will cause condensation to build up
in the air tank. Always drain tank on a
washable surface or in a suitable con-
tainer to prevent damaging or staining
surfaces.
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 approxi-
mately 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.
Risk of Property
Damage. 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 rein-
stalled.
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 compressor life.
NOTE: Use 30W compressor oil or a
heavy duty SAE 30W, non-detergent,
SF grade or better oil DO NOT use
multi-weight automotive engine oils,
they will reduce compressor life. Under
extreme winter condition use SAE-10
weight oil.
NOTE: Crankcase oil capacity is
approximately 48 fluid ounces (1.4 L).
Checking
1. The oil level should be to the
middle of the sight glass (C).
2. If needed remove oil fill plug (A)
and slowly add oil until it reaches
the middle of the sight glass.
C
B
A
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and
drain oil into a suitable container.
3. Replace the oil drain plug (B) and
tighten securely.
4. Slowly add compressor oil until
the oil level is in the middle of the
sightglass (C). NOTE: When filling
the crankcase, the oil flows very
slowly into the pump. If the oil is
added too quickly, it will overflow
and appear to be full.
Risk of Unsafe
Operation. Overfilling
with oil will cause premature
compressor failure. Do not overfill.
5. Replace oil fill plug (A) and tighten
securely.
