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 Bimited
operation unBess filled with oil and
broken in correctly. Make sure
to closeBy follow initial start-up
procedures,
Use air compressor
oiBonBy, Mu_ti=
Viscosity motor oils, like lOW30,
should not be used in an air
compressor. They meavecarbon
deposits on criticaB components,
thus reducing performance and
compressor mife,
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.

To Add Oil
Drain tank to
remease air pressure
before removing the o{I 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.
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" away from the
wal! or other obstructions that will
interfere with the flow of air. 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 r{sk
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 foiIowing
iIIustrations). 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.

MUST be made by a qualified
emectr{cian.
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.
Hnstead of using an extension cord,
increase the working reach of the
air hose by attaching another length
of hose to its end. Attach additiona!
lengths of hose as needed.
Hfan 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 wilI 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.
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 suppiy any
other electdcaI needs.
3.
4.
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 deIay 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 !ocation of various controls and adjustments. Save this manual for future
reference. On/Auto/Off
Switch
On/Auto/Off Switch: 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. 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 vaIve wil! 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 regulaton This pressure is
controlled by the regulator and is
always less than or equal to the tank
pressure.
A09713 14-ENG
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controis the air pressure
shown on the outlet pressure
gauge. Pull the knob out and turn
cIockwise to increase pressure
and countercIockwise 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 styies
of quick-connect plugs: industrial,
automotive (Tru-fiate), and ARC. One
hand push-to-connect operation
makes connections simple and easy.
Brain Vamve:The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
Valve

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 hobs
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 "c!oses",
allowing air pressure to remain inside
the air tank.
Check Valve
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.
Air Intake Filter (not shown) This
filter is designed to clean air coming
into the pump. This filter must
always be clean and ventilation
openings free from obstructions. See
"Maintenance".

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. Puff 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.

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 ell drain plug (B) and
tighten secure.
NOTE: Use an air compressor oil
such as SAE-20 (API CG/CD heavy

Air Filter inspection and
Replacement
Risk of Burns,
Compressor head
and cyminder smeeve are very hot,
Do not touch. AHow compressor to
cool prior to servicing.
A dirty air filter will not allow the
compressor to operate at fall
capacity. Keep the air filter clean at
all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
COV@K
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
NOTE: Once the motor pulley has
been moved from its factory set
location, the grooves of the flywheel
and puIIey 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. Remove belt guard.
3. 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".
5. If the difference is greater or Iess
than 1/16" loosen the set screw
holding the motor drive pulley to
the shaft and adjust the patIey's
position on the shaft until the A1
and A2 measurements are within
1/16" of each other.
6. Torque the motor drive pulley set
screw to 70-80 in.qbs.
7. 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 putIey and
equalize B1 and B2, using care
not to disturb the belt alignment
performed in step 2.
8. Retighten the motor drive paIley
setscrew to 70-80 in.qbs.
9. Reinstall belt guard.
