Code Certification: Products that bear one or more of the following marks: UL,
CUL, ETL, CETL, have been evaluated by OSHA certified independent safety labo-
ratories and meet the applicable Underwriters Laboratories Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to
use your accessory. When the tank pressure drops to the factory set low pressure
the motor will restart automatically. The low pressure at which the motor automati-
cally 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 tank begins to build. It builds to a factory set 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.
Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
ACCESSORIES
Accessories for this unit are available at the store the unit was purchased.
* This air compressor can be operated on a 15 amp circuit if:
1. Voltage supply to circuit is normal.
2. Circuit is not used to supply any other electrical needs (lights, appliances, etc.)
3. Extension cords comply with specifications in owners manual.
4. Circuit is equipped with 15 amp circuit breaker or 15 amp time delay fuse
marked Type D.
If any of the above conditions cannot be met, or if operation of the air 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.
* A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same
rating as the branch circuit on which the air compressor is operated. If the air com-
pressor is connected to a circuit protected by fuses, use dual element time delay
fuses.

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 cor-
rectly. Make sure to closely follow initial start-up procedures.
Multi-Viscosity motor oils, like 10W 30, should not be
used in an air compressor. They leave carbon
deposits on critical components, thus reducing performance and
compressor life. Use air compressor oil only.
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.
1. Place unit on a level surface.
2. Remove oil fill plug (A) and slowly add a com-
pressor 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 approximate-
ly 16 fluid ounces.
3. Replace oil fill plug.

Unpacking
1. Remove all packaging.
It may be necessary to brace or support one side of
the outfit when removing the pallet because the air
compressor will have a tendency to tip.
2. Remove and discard the (4) screws and washers holding the compressor to the
pallet.
3. With the help of another person carefully remove air compressor from pallet
and place on a level surface.

• Located the air compressor at least 12" away from the wall or other obstruc-
tions that will interfere with the flow of air.
• Locate the air compressor as close to the main power supply as possible to
avoid using long lengths of electrical wiring. Long lengths of electrical wiring
could cause power loss to the motor.
• The air filter must be kept clear of obstructions which could reduce air flow to
the air compressor.

Wiring Instructions
Improper electrical installation of this product may
void its warranty and your fire insurance. Have circuit
wiring performed by qualified personnel such as a licensed electri-
cians who is familiar with the current national electrical code and any
prevailing local electrical codes.
RISK OF ELECTRICAL SHOCK. Improper electrical
grounding can result in electrical shock. The wiring
should be done by a qualified electrician
A qualified electrician needs to knows the following before wiring:
1. The amperage rating of the electrical box should be adequate. Refer to the
Specification Chart, in the parts manual, for this information.
2. The supply line should have the same electrical characteristics (voltage, cycle,
phase) as the motor. Refer to the motor nameplate, on side of motor, for this
information.
NOTE: The wiring must be the same as the motor nameplate voltage plus or minus
10%. Refer to local codes for recommended wire sizes, correct wire size, and maxi-
mum wire run; undersize wire causes high amp draw and overheating to the motor.
Electrical wiring must be located away from hot sur-
faces such as manifold assembly, compressor outlet
tubes, heads, or cylinders.
GROUNDING INSTRUCTIONS
This product should be connected to a metallic, permanent wiring system, of an
equipment-grounding terminal or lead on the product.
Voltage and Circuit Protection
Refer to the Parts Manual for the voltage and minimum branch circuit requirements.
Certain air compressors can be operated on a 15 amp circuit if the following condi-
tions are met.
1. Voltage supply through branch circuit is 15 amps.
2. Circuit is not used to supply any other electrical needs (lights, appliances, etc.).
3. 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 marked “D”.
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.

10 - ENGD23269
Air Distribution System
Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pres-
sure rating, plastic pipe can burst from air pressure. Use only metal
pipe for air distribution lines.
The next figure represents a typical air distribution system. The following are tips to
remember when setting up the air compressor’s air distribution system.
●Use pipe that is the same size as the air tank outlet. Piping that is too small will
restrict the flow of air.
●If piping is over 100 feet long, use the next larger size.
●Bury underground lines below the frost line and avoid pockets where conden-
sation can gather and freeze. Apply pressure before underground lines are cov-
ered to make sure all pipe joints are free of leaks.
●A flexible coupling is recommended to be installed between the air discharge
outlet and main air distribution line to allow for vibration.
●A separate regulator is recommended to control the air pressure. Air pressure
from the tank is usually to high for individual air driven tools.

OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR
UNIT. Compare the illustrations with your unit to familiarize yourself with the loca-
tion of various controls and adjustments. Save this manual for future reference.
Description of Operation
Become familiar with these controls before operating the unit.
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. It stops the
motor when the air tank pressure reaches the facto-
ry set “cut-out” pressure.
Safety Valve: If the pressure switch does not shut
off the air compressor at its “cut-out” pressure set-
ting, the safety valve will protect against high pres-
sure by “popping out” at its factory set pressure
(slightly higher than the pressure switch “cut-out”
setting).
Tank Pressure Gauge: The tank pressure gauge
indicates the reserve air pressure in the tank.
Globe Valve (sold separately): Opens and closes air discharge valve. Turn knob
counter-clockwise to open and clockwise to close.
Drain 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” pres-
sure 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 continuous leaking after unit reaches “cut-out” pressure.

How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to “OFF”.
Before Starting
Break-in Procedure
Serious damage may result if the following break-in
instructions are not closely followed.
This procedure is required before the air compressor is put into service and when
the check valve or a complete compressor pump has been replaced.
1. Make sure the On/Auto/Off lever is in the "OFF" position.
2.
Recheck all wiring. Make sure wires are secure at all terminals connections.
Make sure all contacts move freely and are not obstructed.
3. Open the globe valve fully to permit air to escape and prevent air pressure
build up in the air tank during the break-in period.
4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will start.
5. Run the compressor for 30 minutes. Make sure the globe valve is open and
there is minimal air pressure build-up in tank.
6. Check all air line fittings and connections/piping for air leaks by applying a
soap solution. Correct if necessary. NOTE: Minor leaks can cause the air com-
pressor to overwork, resulting in premature breakdown or inadequate perform-
ance.
7. Check for excessive vibration. Readjust or shim air compressor feet, if neces-
sary.
8. After 30 minutes, move the On/Auto/Off lever to "OFF" position and close the
globe valve.
9. Move the On/Auto/Off lever to "ON/AUTO" position. The air receiver will fill to
“cut-out” pressure and the motor will stop.
Before Each Start-Up:
1. Place On/Auto/Off lever to “OFF”.
2. Close the globe valve.
3. Attach hose and accessories. NOTE: A regulator MUST be installed when
using accessories rated at less than 110 PSI.
Too much air pressure causes a hazardous risk of
bursting. Check the manufacturer’s maximum pres-
sure rating for air tools and accessories. The regulator outlet pressure
must never exceed the maximum pressure rating.
How 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. When the tank pressure reaches “cut-out” pressure open the globe valve.
IMPORTANT: When using regulator and other accessories refer to the manufactur-
er-s instructions.
NOTE: Always operate the air compressor in well-ventilated areas free of gasoline
or other combustible vapors. If the compressor is being used to operate a sprayer,
DO NOT place compressor near the spray area.

To ensure efficient operation and longer life of the air compressor outfit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an outfit in a normal working environment oper-
ating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor outfits in an
extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
NOTE: See “Operation” section for the location of controls.
To Check Safety Valve
If the safety valve does not work properly, over-
pressurization may occur, causing air tank rup-
ture 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.

14 - ENGD23269
To Drain Tank
1. Set the On/Auto/Off lever to “OFF”.
2. Close the globe valve.
3. Remove the air tool or accessory.
4. Open the globe valve and allow the air to slowly bleed from the air tank until
tank pressure is approximately 20 psi.
5. Close the globe valve.
6. Drain water from air tank by opening drain valve (counter-clockwise) on bottom
of tank.
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.
7. 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, then reinstalled.
Oil
Checking
1. 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 a air compressor oil such as SAE-20 (API
CG/CD heavy duty motor oil. Under extreme winter con-
ditions use SAE-10 weight oil.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and drain oil into a
suitable container.
3. Replace the oil drain plug (B) and tighten securely
NOTE: Use a air compressor oil such as SAE-20 (API CG/CD heavy duty motor oil.
Under extreme winter conditions use SAE-10 weight oil.
4. Slowly fill crankcase to the top of the fill hole. Crankcase capacity is 16 fluid
ounces (473.2 ml).
Overfilling with oil will cause premature compressor
failure. Do not overfill.
5. Replace oil fill plug (A) and tighten securely.

Air Filter - Inspection and Replacement
Hot surfaces. Risk of burn. Compressor heads are
exposed when filter cover is removed. Allow com-
pressor to cool prior to servicing.
Keep the air filter clean at all times. Do not operate
the air compressor with the air filter removed.

15 - ENG D23269
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 align-
ment, 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 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.
6. Tighten the motor drive pulley set screw to 70-80 in.-lbs.
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 pulley and equalize B1 and
B2, using care not to disturb the belt alignment performed in step 2.
8. Retighten the motor drive pulley setscrew to 70-80 in.-lbs.
9. Reinstall belt guard.
A dirty air filter will not allow the compressor pump to operate at full capacity.
Before you use the compressor pump, check the air filter to be sure it is clean and
in place.
If it is dirty, replace it with a new filter. On some models,the filter may be removed
by using a pair of needle nose pliers or a screwdriver. Pull or pry out the old filter
and carefully clean the filter area. Push in the new air filter.
Air Compressor Pump Intake and Exhaust Valves
Once a year have a Trained Service Technician check the air compressor
pump intake and exhaust valves.
Inspect Air Lines and Fittings for Leaks
1. Turn the air compressor on to inspect for air leaks.
2. Apply a soap solution to all air line fittings and connections/piping.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting
in premature breakdown or inadequate performance.

SERVICE AND ADJUSTMENTS
Unit cycles automatically when power is on. When doing
Maintenance, you may be exposed to voltage sources, com-
pressed air or moving parts. Personal injuries can occur.
Before performing any Maintenance or repair, unplug the compressor and bleed off
all air pressure.
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST
BE PERFORMED BY TRAINED SERVICE TECHNICIAN.
Before servicing:
●Unplug or disconnect electrical supply to the air compressor.
●Bleed tank of pressure.
●Allow the air compressor to cool.
To Replace or Clean Check Valve
1. Release all air pressure from air tank. See “To Drain Tank” in the Maintenance
section.
2. Unplug unit.
3. Using an adjustable wrench loosen
outlet tube nut at air tank and pump.
Carefully move outlet tube away from
check valve.
4. Using an adjustable wrench loosen
pressure relief tube nut at air tank and
pressure switch. Carefully move pres-
sure relief tube away from check valve.
5. Unscrew the check valve (turn coun-
terclockwise) using a 7/8” open end
wrench. Note the orientation for
reassembly.
6. Using a screwdriver, carefully push the
valve disc up and down. NOTE: The
valve disc should move freely up and
down on a spring which holds the
valve disc in the closed position, if not
the check valve needs to be cleaned or replaced.
7. Clean or replace the check valve. A solvent, such
as paint or varnish remover can be used to clean
the check valve.
8. Apply sealant to the check valve threads.
Reinstall the check valve (turn clockwise).
9. Replace the pressure release tube. Tighten nuts.
10. Replace the outlet tube and tighten nuts.
11. Perform the Break-in Procedure. See “Break-in
Procedure” in the Operation section. In closed position disc is visible.

To Replace Belt
Serious injury or damage may occur if parts of the
body or loose items get caught in moving parts.
Never operate the unit with the belt guard removed. The belt guard should
be removed only when the compresor is unplugged.
1. Unplug compressor.
2. Remove the front of the belt guard by
disengaging the snaps. Insert a flat
bladed screwdriver at each snap loca-
tion and pry the beltguard apart.
3. Loosen the wing nut on hold down
plate and tilt motor to allow for easy
removal or installation of the belt.
4. Remove belt.
5. Replace belt. NOTE: The belt must be
centered over the grooves on the fly-
wheel and motor pulley.
6. Turn the wing nut on the hold down
plate until it makes contact with the
washer, plus one additional turn.
7. Replace the belt guard.

Wing Nut
Motor
This motor has a manual 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. Place the On/Auto/Off lever in the Off position.
2. Allow the motor to cool.
3. Depress the red reset button on the motor.
4. Place the On/Auto/Off lever in the On/Auto postion
to restart the motor.
IMPORTANT: If the overload protector shuts the motor
off frequently, check for a possible voltage problem.
Low voltage can also be suspected when:
1. The motor does not get up to full power or speed.
2. Fuses blow out when starting the motor; lights dim
and remain dim when motor is started and is running.

STORAGE
Before you store the air compressor, make sure you do the following:
1. Review the "Maintenance" section on the preceding pages and perform sched-
uled maintenance as necessary.
2. Set the On/Auto/Off lever to “OFF”.
3. Close the globe valve.
4. Remove the air tool or accessory.
5. Open the globe valve and allow the air to slowly bleed from the air tank until
tank pressure is approximately 20 psi.
6. Drain water from air tank by opening drain valve (counter-clockwise) on bottom
of tank.
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.
7. After the water has been drained, close the drain or drain valve.
NOTE: If drain valve is plugged, release all air pressure. The valve can then
be removed, cleaned, then reinstalled.
8. Protect the air hose from damage (such as being stepped on or run over).
