SPEED AND WIRING
The no-load speed of the electric motor varies by model and
specification. The motor speed is not constant and decreases
under a load or with lower voltage. For voltage, the wiring
in a shop is as important as the motor’s horsepower rating.
A line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance will
be too light for a greater distance. A line that can support one
power tool may not be able to support two or three tools.
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock
by providing an escape wire for the electric current. This
air compressor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
The conductor with insulation having an outer surface that
is green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120-V circuit and has
a grounding plug similar to the plug illustrated in Figure 1.
Only connect the product to an outlet having the same con-
figuration as the plug. Do not use an adapter with this product.
Never use an electrical adapter with this grounded plug.
WARNING:
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
air compressor’s plug. When using the air compressor at
a considerable distance from the power source, use an
extension cord heavy enough to carry the current that the
compressor will draw. An undersized extension cord will
cause a drop in line voltage, resulting in a loss of power
and causing the motor to overheat. Use the chart provided
below to determine the minimum wire size required in
an extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (ULC) should be used.

NOTE: AWG = American Wire Gauge
When working with the air compressor outdoors, use an
extension cord that is designed for outside use. This is
indicated by the letters “WA” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
fNOTE: Use longer air hoses instead of long extension
cords. Your air compressor will run better and last longer.
ELECTRICAL CONNECTION
This air compressor is powered by a precision built electric
motor. It should be connected to a power supply that is
120 volts, 60 Hz, AC only (normal household current).
Do not operate this tool on direct current (DC). A substantial
voltage drop will cause a loss of power and the motor will
overheat. If the air compressor does not operate when
plugged into an outlet, double check the power supply.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with a
power tool. Failure to do so can result in serious personal
injury.
WARNING:
Check the extension cords before each use. If damaged,
replace immediately. Never use the air compressor with
a damaged cord since touching the damaged area could
cause electrical shock resulting in serious personal injury.

FEATURES
KNOW YOUR AIR COMPRESSOR
See Figure 2.
Before attempting to use this product, familiarize yourself with all
operating features and safety rules.
OIL-FREE UNIVERSAL MOTOR
Your air compressor features permanently lubricated bearings.
ON/OFF POWER SWITCH
This switch is used to start or stop the air compressor. Moving the
switch to the (ON) position will provide automatic power to the
pressure switch which will allow the motor to start when the air
tank pressure is below the factory set cut-in pressure. When in
the (ON) position, the pressure switch stops the motor when the
air tank pressure reaches the factory set cut-out pressure. Moving
the switch to the (OFF) position will remove power from the motor
and stop the air compressor.
MOTOR THERMAL OVERLOAD
The electric motor has a thermal overload protector. If the motor
overheats for any reason, the thermal overload will cut off power,
thus preventing the motor from being damaged. Wait until the
motor is cool. Motor resets automatically.
AIR INTAKE FILTER
This filter is designed to clean air coming into the pump. To ensure
the pump continually receives a clean, cool, dry air supply this
filter must always be clean and ventilation opening free from
obstructions.
AIR COMPRESSOR PUMP
To compress air, the piston moves up and down in the cylinder.
On the down stroke, air is drawn in through the air intake valve
while the exhaust valve remains closed. On the upstroke, air is
compressed, the intake valve closes and compressed air is forced
out through the exhaust valve, into the discharge line, through the
check valve and into the air tank.
SAFETY VALVE
This valve is designed to prevent system failures by relieving
pressure from the system when the compressed air reaches a
predetermined level. The valve is preset by the manufacturer and
must not be modified in any way. To verify the valve is working
properly, pull on the ring. Air pressure should escape. When the
ring is released, it will reset.
DRAIN VALVE
The drain valve is used to remove moisture from the air tank after
the air compressor is shut off.
TANK PRESSURE GAUGE
The tank pressure gauge indicates the pressure of the air in the tank.
REGULATOR PRESSURE GAUGE
The current line pressure is displayed on the regulator pressure gauge.
This pressure can be adjusted by rotating the pressure regulator knob.
PRESSURE REGULATOR KNOB
Use the pressure regulator knob to adjust the amount of air being
delivered through the hose.
The air pressure coming from the air tank is controlled by the regulator
knob. Turn the pressure regulator knob clockwise to increase discharge
pressure and counterclockwise to decrease discharge pressure.

OPERATION
APPLICATIONS
Air compressors are utilized in a variety of air system
applications. Match hoses, connectors, air tools, and
accessories to the capabilities of the air compressor.
You may use this tool for purposes listed below:
Operating air powered tools requiring less than
3.2 SCFM @ 90 PSI.
Powering pneumatic nail guns, inflating tires, cleaning /
blowing with pressurized air.
USING THE AIR COMPRESSOR
See Figures 9 - 10.
Ensure the tank drain valves are closed (see Fig. 9).
Ensure the ON/OFF switch is in the OFF (O) position
and the air compressor is unplugged (see Fig. 9).
Ensure the pressure regulator knob is turned fully
counterclockwise (see Fig. 9).
If not already installed, attach the hose to the compressor.
Connect the air powered tools to the air hose by
inserting the male quick-connect plug to the quick-
coupler at the end of the hose (see Fig. 10).
Connect the power cord to the power supply.
Turn the ON/OFF switch to the ON (I) position.
Rotate the pressure regulator knob to the desired
line pressure. Turning the knob clockwise increases
air pressure at the outlet; turning the knob
counterclockwise reduces air pressure at the outlet.
NOTE: Before connecting or disconnecting air tools, turn
the regulator knob counterclockwise to stop the flow of air.
Following all safety precautions in this manual and the
manufacturer’s instructions in the air tool manual, you
may now use your air-powered tool.
If using an inflation accessory with a quick-connect
fitting, control the amount of air flow with the pressure
regulator knob. Turning the knob fully counterclockwise
will completely stop the flow of air.
NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure
than needed will drain air from the tank more rapidly
and cause the unit to cycle on more frequently.
When finished, always drain the tank and unplug the unit.
Never leave the unit plugged in and/or running unattended.
WARNING:
Check the air tool manual to ensure the correct air pressure
regulator setting for optimum operation of your air tools. If you
are using an air tool not originally included with the air tool kit

WARNING:
If air leaks after the ring has been released, or if the
valve is stuck and cannot be actuated by the ring,
do not use the air compressor until the safety valve
has been replaced. Use of the air compressor in this
condition could result in serious personal injury.
OPERATION
DRAINING THE TANK
See Figure 11.
To help prevent tank corrosion and keep moisture out of
the air used, the tank of the compressor should be drained
daily.
To drain:
Verify that the compressor is turned off.
Holding the handle, tilt the compressor toward the drain
valves so that it’s set in a lower position.
Open the drain valves by rotating them ¼ turn
counterclockwise.
Keep the compressor tilted until all moisture has been
removed.
Drain moisture from tank into a suitable container.
NOTE: Condensate is a polluting material and should
be disposed of in compliance with local regulations.
If drain valve is clogged, release all air pressure by
pulling the safety valve. Remove and clean valve, then
reinstall.
Close the drain valves by rotating them ¼ turn clockwise .
CHECKING THE SAFETY VALVE
See Figure 12.
The safety valve will automatically release air if the air
receiver pressure exceeds the preset maximum. The valve
should be checked before each day of use by pulling the
ring by hand.
Turn the air compressor on and allow the tank to
fill. The compressor will shut off when the pressure
reaches the preset maximum.
Turn the air compressor off.
Pull the ring on the safety valve to release air for twenty
seconds.
Release the ring. Air must immediately stop escaping
when the ring is released. Any continued loss of air
after releasing the safety valve ring indicates a problem
with the safety valve. Discontinue use and seek service
before continued use of the air compressor.
WARNING:
Unplug the air compressor and release all air from
the tank before servicing. Failure to depressurize tank
before attempting to remove valve may cause serious
personal injury.
WARNING:
Do not attempt to tamper with safety valve. Anything
loosened from this device could fly up and hit you.
Failure to heed this warning could result in death or
serious personal injury.

END OF OPERATION/STORAGE
Turn the ON/OFF switch to the OFF (O) position.
Unplug power cord from wall outlet and wrap around
handle area to prevent damage when not in use.
Wearing safety glasses, drain tank of air by pulling the
ring on the safety valve. Use other hand to deflect fast
moving air from being directed toward your face.
Drain tank of condensation by opening drain valves on
bottom of tank. Tank pressure should be below 10 PSI
when draining tank.
Air hose should be disconnected from compressor and
hung open ends down to allow any moisture to drain.
Compressor and hose should be stored in a cool, dry
place.
OPERATION
OVERLOAD PROTECTOR
This air compressor is equipped with a thermal overload
device which will turn the air compressor off automatically,
if the air compressor becomes overheated. If the motor
turns OFF repeatedly, check for the following possible
causes first: Low Voltage from the outlet. Lack of proper
ventilation or outside air or room temperature too high.
Extension cord too long or wrong gauge wire used.
To reset the air compressor:
Turn the air compressor off.
Unplug the air compressor and allow it to cool for 30
minutes.
Plug the air compressor into an approved outlet.
Turn the air compressor on.
DUTY CYCLE:
To avoid overheating of the electric motor, this
compressor is designed for intermittent operation as
indicated on the dataplate: S3-50 means 5 minutes ON
and 5 minutes OFF.
If the compressor run time exceeds the S3-50 duty
cycle, then the application requires more air than the
compressor is capable to deliver.
To ensure tool performance, the SCFM output of the
compressor should exceed the CFM requirement of the
tool by 20%.

MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing
dust. If operation is dusty, also wear a dust mask.
WARNING:
Always release all pressure, disconnect from power
supply, and allow unit to cool to the touch before
cleaning or making repairs on the air compressor.
GENERAL MAINTENANCE
Humidity in the air causes condensation to form in the air
tank. This condensation should be drained daily and/or
every hour, using the instructions found in Draining the
Tank.
The safety valve automatically releases air if the air
receiver pressure exceeds the preset maximum. Check
the safety valve before each use following the instructions
found in Checking the Safety Valve.
Inspect the tank yearly for rust, pin holes, or other
imperfections that could cause it to become unsafe.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
BEARING LUBRICATION
All the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication of the bearings is required.
WARNING:
Do not at any time let brake uids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury. Electric tools used on berglass material, wall-
board, spackling compounds, or plaster are subject
to accelerated wear and possible premature failure
because the berglass chips and grindings are highly
abrasive to bearings, brushes, commutators, etc.
Consequently, we do not recommend using this tool for
extended work on these type of materials. However, if
you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
