GLOSSARY
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.
DUTY CYCLE
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.

INSTALLATION
HOW TO SET UP YOUR UNIT
Location of the Air Compressor
• Locate the air compressor in a
clean, dry and well ventilated
area.
• The air compressor should be
located at least 12" (304.8 mm)
away from the wall or other
obstructions that will interfere
with the flow of air.
• Place the air compressor on a flat
level surface in the vertical posi-
tion resting on the rubber bum-
pers and wheels
• The air compressor pump and
shroud are designed to allow for
proper cooling. The ventilation
openings on the compressor are
necessary to maintain proper
operating temperature. Do not
place rags or other containers on
or near these openings.
GROUNDING INSTRUCTIONS
Risk of Electrical
Shock. In the event
of a short circuit, grounding reduces
the risk of shock by providing an
escape wire for the electric current.
This air compressor must be
properly grounded.

10- ENG
D21683
4. If these grounding instructions
are not completely understood,
or if in doubt as to whether the
compressor is properly grounded,
have the installation checked by a
qualified electrician.
Risk of Electrical
Shock. IMPROPER
GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.
Do not modify the plug provided. If
it does not fit the available outlet, a
correct outlet should be installed by
a qualified electrician.
Repairs to the cord set or plug
MUST be made by a qualified elec-
trician.
EXTENSION CORDS
Using extension cords is not recom-
mended. The use of extension cords
will cause voltage to drop resulting in
power loss to the motor and overheat-
ing.
Instead of using an extension cord,
increase the working reach of the
air hose by attaching another length
of hose to its end. Attach additional
lengths of hose as needed.
If an extension cord must be used, be
sure it is:
• a 3-wire extension cord that has a
3-blade grounding plug, and a 3-
slot receptacle that will accept the
plug on the product
• in good condition
• no longer than 50 feet
• 12 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 10 AWG and 8 AWG
may also be used. DO NOT USE
14 OR 16 AWG.)
VOLTAGE AND CIRCUIT
PROTECTION
Refer to the specification chart for the
voltage and minimum branch circuit
requirements. Certain air
compressors can
be operated on a 15 amp circuit if
the following conditions are met.
1. Voltage supply to circuit must
comply with the National Electrical
Code.
2. Circuit is not used to supply any
other electrical needs.
3. Extension cords comply with
specifications.
4. Circuit is equipped with a 15 amp
circuit breaker or 15 amp time
delay fuse. NOTE: If compressor
is connected to a circuit protected
by fuses, use only time delay
fuses. Time delay fuses should be
marked "D" in Canada and "T" in
the US.
If any of the above conditions cannot
be met, or if operation of the com-
pressor repeatedly causes interruption
of the power, it may be necessary to
operate it from a 20 amp circuit. It is
not necessary to change the cord set.

11- ENG D21683
DESCRIPTION OF OPERATION
Become familiar with these controls
before operating the unit.
On(—)/Auto/Off (O) Lever: Turn this
switch to "On/Auto" to provide auto-
matic 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 pres-
sure gauge indicates the reserve air
pressure in the tank.
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air pres-
sure 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.
Regulator: Controls the air pressure
shown on the outlet pressure gauge.
Pull the knob out and turn clockwise
to increase pressure and counterclock-
wise to decrease pressure. When the
desired pressure is reached push knob
in to lock in place.
Universal Quick-Connect Body: The
universal quick-connect body accepts
the three most popular styles of quick-
connect plugs: Industrial, automotive
(Tru-flate), and ARO.
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.

Check
Check Valve
Valve:
When the
air com-
pressor 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: The pressure
release valve
Pressure
Release Valve
located on
the side of
the pressure
switch, is
designed to
automatically
release com-
pressed 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
after the unit reaches "cut-out" pressure.
Motor Overload Protector (not
shown): The motor has an automatic
reset thermal overload protector. If
the motor overheats for any reason,
the overload protector will shut off the
motor. The motor must be allowed to
cool down before restarting. The com-
pressor will automatically restart after
the motor cools.

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 work-
ing environment operating on a daily
basis. If necessary, the schedule
should be modified to suit the condi-
tions under which your air compressor
is used. The modifications will depend
upon the hours of operation and the
working environment. Compressors
in an extremely dirty and/or hostile
environment will require a greater fre-
quency 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 safety glasses 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: All compressed air systems
generate condensate that accumulates
in any drain point (e.g., tanks, filter, after-
coolers, dryers). This condensate con-
tains lubricating 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"
and unplug unit.
2. Pull the regulator knob out and

sure gauge
drops when an
accessory is
used.
It is normal for "some"
pressure drop to occur. If there is an excessive amount of pressure drop when
the accessory is used, adjust
the regulator following the
instructions in the "Description
of Operation" paragraph in the
"Operation" section.
NOTE: Adjust the regulated
pressure under flow
conditions (while accessory is
being used).

Noise. Possible defect in safety
valve. Operate safety valve manually by pulling on ring. If valve still
leaks, it should be replaced.
Defective check valve. Remove and clean, or replace.
Compressor is
not supplying
enough air to
operate acces-
sories.
Prolonged excessive use
of air. Decrease amount of air usage.
Compressor is not large
enough for air requirement. Check the accessory air requirement. If it is higher
than the SCFM or pressure
supplied by your air
compressor, you need a
larger compressor.
