CFM: Cubic feet per minute,
SCFM: Standard cubic feet per
minute: a unit of measure of air

PSIG'. Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks; LIL, GUL, 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, sir tank pressure drops as you
cont[nu@ to use your accQssory.
When the tank pressure drops to a
certain low level the motor will restart
automatically. The low pressure at
which the motor automaticai)y
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 t_nk
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.

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,

HOW TO SET UP YOUR
UNIT
Location of the Air Compressor
Loce_e the air compressor in a clean,
dry and well ventilated area, The air
compressor should be located at
least 12' away from the wall or other
obstructions that will interfere with
the flow of air. The air compressor
pump and shroud are designed to
allow far proper cooling, The
ventilation openings on the
compressor are necessary to
maintain proper operating
temperature, Do not place r&gs or
other COl]t&ipers on or near these
openings
GROUNDING INSTRUCTIONS
RISK OF
ELECTRICAL
SHOCK. In the event of a short
circuit, grounding reduces the rlsk
of shock by providing an escape
wire for the electric current. This
air compressor must be properly
grounded.
The portable air compressor is
equipped with a cord having a
grounding wire with an appropriate
grounding plug (see following
illustrations). The plug must be used
with an outlet that has been installed
and grounded in accordance with all
local codes and ordinances,
IMPORTANT.' The outlet being used
must be installed and grounded in
accordance with all local codes and
ordinances.
2. Make sure the outlet being used
has the same configuration as
the grounded plug DO NOT
USE AN ADAPTER. See
illustration,
_Groundod Outl_t_
/
G re tllldlrlg PIll
31 Inspect the plug and cord before
each Use, Do not use if there ere
aigns of damage.
41 If these grounding instructions
are riot completely undcrstood,
or if in doubt 4_sto whether the
compressor is properly
grounded, have the installation
checked by a qualified
electrician.
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 e qualified electrician.
Repairs to the cord set or plug
MUST be made by a qualified
electrician.
The cord set and plug with this
unit containa a grounding pin.
This plug MUST be used with a
grounded outlet.
D26336 10- ENG

E:_te_lsion Cords
Using extension cords is not
recommended. The use of extension
cords will cause voltage to drop
resulting in power loss to the motor
ang overheating.
Attacn extra air hoses at tt/e air outlet
instead of us)rig extension cords.
If ar_ extension cord must be used, be
sure it is;
a 3-wire extension cord that has
a3-blade grounding plug, and a
3-stot receptacle that will accept
the plug on the product
In good condition

12 gauge (AWG) or Jarger. (WJr_
_lze Jncrsases as gauge number
decreases. 10 AWG and 8 AWG
may also be used, DO NOT USE
14 OR 16AWG)
Voltage a[_d Circuii; Protection
Refer to the Specification Chart for
the voltage and minimum branch
circuit requirements.
Certain airoompressor_ can be
operated on a 15 amp circuit if the
following conditions are met.
1. Voltage supply through branch
circuit is 15 crops.
2. Circuit is not used to supply any
other electrical needs (lights,
appliances, etc.).
3. E".xtertsioncords comply with
speciticatlons.
4. Circuit is equipped with a 15
amp circuit breaker or 15 amp
tinle delay ruse. NOTE: tf
compressor is connected to a
circuit protected by fuses, u_e
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
compressor 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.

READ THiS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future

Description of Operation
Become familiar wlth these controls
before operating th_ uniL
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.
Pressure Switch: The pressure
switch automatically starts the motor
when the air tank pressure drops
below the factory set "cutqn"
pressure. It stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure,
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "out-out" pressure setting, the
safety vane will protect aga}nst high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "eut-o,,t*
setting).
Outlet Pressure Gauge; The outlet
pressure gauge indicates the air
_>¢essureavaUable 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
D20336
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controls the _ir 13rossurQ
shown on the outlet pressure gauge,
Pull the knob out and turn clockwise
to increase pressure and
counterclockwise to decrease
pressure. When the desired pressure
Is reached push knob in to lock in
place.
Drain Valve.' The drain valve is
located at the base of the air tank
and is u_ed to drain condensation at
the end of each use,
Cooling System (net 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 blew air through the
vent holes in large amounts. You
know that the cooling system is
working when air Is being expelled.
12- ENG

Air Compressor Pump (not shown);
Compresses air into the air tank.
Working air Je not avaiJable until the
compressor has raised the air tank
pressure above that required at the
air outlet.
Check Valve: When the air
comDressor is operating, the cheek
valve is "open", allowing compressed
air to enter the sir tank When the air
compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure re remain inside
the sir tank.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off ]ever to

Before First Start-up
Break-in Procedure
Serious damage
may result if the
following break-in instructions are
not closely followed,
Thisprocedure is required before the

valve is open a,nd there is
minima] air pressure build-up in
tank,
6, After 15 minutes, close the drain
valve (clockwise). The air receiver
will fill to "cut-out" pressure and
the motor will stop,
The compressor is now ready for use.
13-ENQ D28336

Befo]e Each Start-Up:
I. Place On/Auto/Off lever to

2. Pull regulator knob out, turn
counterclockwise until it stops.
Push knob in to lock in place.
3Attach hose and accessories.
NOTE: The hose or accessory
will reuu_re e quick connect plug
if the air outlet is equipped with a
quick connect socket.
I_1_ Too much air
pressure causes a
hazardous risk of bursting. Check
the manufacturer's maximum
pressure rating for air tools and
accessories, The regulator outlet
pressure must never exceed the
maximum pressure rating.
}-low to Start:
1. Turn the On/Auto/Off lever to
"AUTO" and allow tank pressure
to build, Motor will stop when
tank pressure reaches "cut-out"
pressure.
2, Pull the regulator knob out and
turn clockwise to increase
pressure. Whet_ the desired
pressure is reached push knob in
