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.
_Use air compressor
oil only. Multi-
Viscosity motor oils, like lOW 30,
should not be used in an air
compressor. They leave carbon
deposits on critical components,
thus reducing performance and
compressor life.
NOTE: Use an air compressor oil
such as Sears item number 9-16426
or SAE-20 (API CG/CD heavy duty
motor oil. Under extreme winter
conditions use SAE-10 weight oil.
11_ENG D30090

To Add Oil
Drain tank to
release air pressure
before removing the oil fill cap or
oil drain plug.
1. Place unit on a level surface.
2. Remove oil fill plug (A) and
slowly add compressor oil until it
is even with the top of the oil fill
hole. NOTE: Do not allow oil to
be lower than 3/8" (6 threads)
from the top at any time. 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.
NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.
3. Replace oil fill plug.
Air Compressor Location
•Locate 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 filter and flywheel must
be kept clear of obstructions
which could reduce air flow to
the air compressor.
The air compressor requires
fresh air flow for proper cooling.
DO NOT ALLOW THE
COMPRESSOR TO GET WET.
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
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.
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.

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
Using extension cords is not
recommended. The use of extension
cords 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.
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.
Risk of Unsafe
Operation. 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.
3.
4.
Circuit is not used to supply any
other electrical needs.
Extension cords comply with
specifications.
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
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.
120/240 Dual Voltage Motor
This model has a dual voltage motor,
120 and 240 volt. It is wired for 120
volt but can be converted to 240 volt
operation. Instructions for connecting
the motor for operation at 240 volt
can be found printed on the label
attached to the side of the motor.
F_lWhen converting to
240V operation, the

Switch
Outlet
Pressure Gauge
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 "cut-in"
pressure. The pressure switch 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 "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).
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure 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.
D30090 14- ENG
Tank Pressure Gauge: The tank
pressure 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
counterclockwise 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 ARC. One
hand push-to-connect operation
makes connections simple and easy.
Brain 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 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 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 after unit
reaches "cut-out" pressure.

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.
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
1. Set the On/Auto/Off lever to
"OFF" and unplug unit.
2. Pull the regulator knob out and
turn clockwise to set the outlet
pressure to zero.
3. Remove the air tool or
accessory.
4. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately
20 psi. Release safety valve ring.
5. Drain water from air tank by
opening drain valve (counter-
clockwise) 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.
6. After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, and
reinstalled.
Oil
Risk of Bursting.
Drain tank to
release air pressure before
removing the oil fill cap or oil drain
plug.
Checking
1. Place unit on a level surface.
2. Remove the oil fill plug (A). The
oil level should be even with the
top of the fill hole and no lower
than 6 threads from the top of fill
hole.
2. If needed, slowly add oil until it
reaches the top of fill hole.
NOTE: Use an air compressor oil
such as SAE-20 (API CG/CD heavy
duty motor oil. Under extreme winter
conditions use SAE-10 weight oil.
Changing
1. Place unit on a level surface.
2. Remove the oil fill plug (A).
3. Remove the oil drain plug (B) and
drain oil into a suitable container.
4. Replace the oil drain plug (B) and
tighten secure.
NOTE: Use an air compressor oil
such as SAE-20 (API CG/CD heavy
duty motor oil. Under extreme winter
conditions use SAE-10 weight oil.
5. Slowly fill crankcase to the top of
the fill hole. Crankcase capacity
is 16 fluid ounces (473.2 ml).
6. Replace oil fill plug (A) and
tighten securely

Air Filter Inspection and
Replacement
Risk of Burns.
Compressor head
and cylinder sleeve are very hot.
Do not touch. Allow compressor to
cool prior to servicing.
A dirty air filter will not allow the
compressor to operate at full
capacity. Keep the air filter clean at
all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
cover.
IMPORTANT: Do not operate the
compressor with the air filter
removed.
3. Place new air filter into filter
cover. Refer to the "Repair Parts"
for the correct part number.
4. Replace air filter cover and lock
into place.
Motor Pulley/Flywheel
Alignment
NOTE: Once the motor pulley has
been moved from its factory set
location, the grooves of the flywheel
and pulley must be aligned to within
1/16" to prevent excessive belt wear.
The air compressor flywheel and
motor pulley must be in-line (in the
same plane) within 1/16" to assure
belt retention within flywheel belt
grooves. To check alignment,
perform the following steps:
1. Unplug air compressor from
power source.
2.
3.
Remove belt guard.
Place a straightedge against the
outside of the flywheel and the
motor drive pulley.
4. Measure the distance between
the edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no
more than 1/16".
[LT MOTOR PULLEY

8.
if the difference is greater or less
than 1/16" loosen the set screw
holding the motor drive pulley to
the shaft and adjust the pulley's
position on the shaft until the A1
and A2 measurements are within
1/16" of each other.
Torque the motor drive pulley set
screw to 70-80 in.-Ibs.
Visually inspect the motor drive
pulley to verify that it is
perpendicular to the drive motor
shaft. Points B1 and B2 of Figure
should appear to be equal. If
they are not, loosen the setscrew
of the motor drive pulley and
equalize B1 and B2, using care
not to disturb the belt alignment
performed in step 2.
Retighten the motor drive pulley
setscrew to 70-80 in.-Ibs.
9. Reinstall belt guard.
