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.
The portable air compressor is
equipped with a cord having a ground-
ing wire with an appropriate grounding
plug (see following illustrations).
1. The cord set and plug with this
unit contains a grounding pin.
This plug MUST be used with a
grounded outlet.
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.
g [-'_LGrounded
Grounding Pin
3.
Inspect the plug and cord before
each use. Do not use if there are
signs of damage.
4.
If these grounding instructions are
not completely understood, or if in
doubt as to whether the compres-
sor 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
electrician.
EXTENSION CORDS
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 (15.2 m)
• 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.)
The use of an
_ " " "-- undersized extension
cord will cause voltage to drop
resulting in power loss to the motor
and overheating. 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. Always use an air
hose rated 300 PSI or greater.
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 compres-
sor 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.
TRANSPORTING
When transporting the compressor in a
vehicle, trailer, etc., make sure the tank
is drained and the unit issecured with
straps to prevent tipping. Use care
when driving to prevent tipping the unit
over in the vehicle. Damage can occur
to the compressor or surrounding
items if the compressor is tipped.

Switch
Description of Operation
Become familiar with these controls
before operating the unit.
Auto (I)/Off (O) Switch: Turn this
switch "Auto (I)" to provide automatic
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
N004395
':Regulator
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).
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.
Tank Pressure Gauge: The tank pres-
sure gauge indicates the reserve air
pressure in the tank.
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.
12- ENG
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. One hand push-
to-connect operation makes connec-
tions simple and easy.
Drain Valve:
The drain valve is
located at the
base of the air
tank and is used
to drain conden-
sation at the end of each use.
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 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:
The pressure
release valve
located on the
side of the pres-
sure switch, is
designed to
automatically release compressed air
from the compressor head and the out-
let tube when the air compressor reach-
es "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.
Air Intake Filter:
This filter is
designed to clean
air coming into the
pump. This filter
must always be
clean and ventila-
tion openings free
from obstructions. See "Maintenance".
Motor Overload Protector: The motor
has a 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. To restart:
1. Set the Auto/Off switch to "Off"
and unplug unit.
2. Allow the motor to cool.
3. Plug the power cord into the
correct branch circuit receptacle.
4. Set the Auto/Off lever to "Auto"
position.
