GLOSSARY
Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per
minute; a unit of measure of air deliv-
ery.
PSIG: Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by OSHA certified
independent safety laboratories 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 a
certain low level the motor will restart
DUTY CYCLE
Air compressors should be operated
on not more than a 50% duty cycle.
This means an air compressor that
pumps air more than 50% of one
automatically. The low pressure at
which the motor automatically
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 certain
high pressure before the motor auto-
matically 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 elec-
tricity from electrical panel to outlet.
To Lock Out Power: Place a lock on
the line power switch so no one else
can turn on the power.
hour is considered misuse, because
the air compressor is undersized for
the required air demand. Maximum
compressor pumping time per hour is
30 minutes.
Accessories for this unit are available at the store the unit was purchased.
ACCESSORIES
* 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 compres-
sor 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.

Unpacking
1. Remove all packaging.
It may be neces-
sary 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.
To Add Oil To Pump
Compressors are
shipped without oil.
A small amount of oil may be pres-
ent 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 fol-
low 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 compres-
sor oil only.
1. Remove the oil drain plug (B) and
washer (C).

GROUNDING INSTRUCTIONS
This product should be connected to
a metallic, permanent wiring system,
or an equipment-grounding terminal
or lead on the product and comply
with national and local electrical
codes.
Refer to the product specification
found in the front of this manual for
the voltage and minimum branch cir-
cuit requirements.
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.
Wiring Instructions
RISK OF ELECTRI-
CAL SHOCK.
Improper electrical grounding can
result in electrical shock. The
wiring should be done by a quali-
fied electrician to comply with
national and local electrical codes.
A qualified electrician needs to knows
the following before wiring:
1. The amperage rating of the elec-
trical box should be adequate.
Refer to the product specifica-
tions, found in the front of this
manual, for this information.
2. The supply line should have the
same electrical characteristics
(voltage, cycle, phase) as the
motor. Refer to the motor name-
plate, 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 maximum wire run;
undersize wire causes high amp draw
and overheating to the motor.
Electrical wiring
must be located
away from hot surfaces such as
manifold assembly, compressor
outlet tubes, heads, or cylinders.

12-ENGD22944
• 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 condensation can gather
and freeze. Fill lines with air pres-
sure before covering to make
sure pipe joints are free from
leaks.
• Install a flexible coupling
between the air discharge outlet
and main air distribution line to
allow for vibration.
NOTE: The shut-off valve is not sup-
plied with this unit. You must purch-
sase the shut-off valve separately.
• A separate regulator is recom-
mended to control the air pres-
sure. Air pressure from the air
tank is usually too high for indi-
vidual air driven tools.

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" pres-
sure. It 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).
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.
Regulator (sold separately, not shown): An air pressure regulator or a sepa-
rate air transformer which combines the functions of air regulation and/or mois-
ture and dirt removal is recommended for most applications.
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 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 continuous leaking 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".
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. NOTE: The shut-off
valve is not supplied with this unit. You must purchase the shut-off
valve separately.
4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will
start.
5. Run the compressor for 20 minutes. Make sure the globe valve is open
and there is minimal air pressure build-up in tank.

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 manu-
facturer-s instructions.
NOTE: Always operate the air compressor in well-ventilated areas free of gaso-
line or other combustible vapors. If the compressor is being used to operate a
sprayer, DO NOT place compressor near the spray area.
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 175 PSI.
Too much air pressure causes a hazardous risk of
bursting. Check the manufacturer’s maximum pressure
rating for air tools and accessories. The regulator outlet pressure must
never exceed the maximum pressure rating.
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
compressor to overwork, resulting in premature breakdown or inadequate
performance.
7. Check for excessive vibration. Readjust or shim air compressor feet, if
necessary.
8. After 20 minutes, close the globe valve. The air receiver will fill to "cut-out"
pressure and the motor will stop.

To ensure efficient operation and longer life of the air compressor outfit, a rou-
tine maintenance schedule should be prepared and followed. The following
routine maintenance schedule is geared to an outfit in a normal working envi-
ronment operating on a daily basis. If necessary, the schedule should be modi-
fied to suit the conditions under which your compressor is used. The modifica-
tions 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.
Unit cycles automatically when power is on. When per-
forming maintenance, you may be exposed to voltage
sources, compressed air, or moving parts. Personal injuries can occur.
Before performing any maintenance or repair, disconnect power source
from the compressor and bleed off all air pressure.

4. Sowly add compressor oil until
the oil level is in the middle of the
sightglass (C). NOTE: When fill-
ing 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.
Overfilling with oil
will cause prema-
ture compressor failure. Do not
overfill.
5. Replace oil fill plug (A) and tight-
en securely.
Oil
NOTE: Use a air compressor oil such
as SAE-30 (API CG/CD heavy duty
motor oil). Under extreme winter con-
ditions use SAE-20 weight oil. NOTE:
Crankcase oil capacity is approxi-
mately 60 fluid ounces (1.8 L).
Checking
1. The oil level should be to the mid-
dle of the sight glass (C).
2. If needed remove oil fill plug (A)
and slowly add oil until it reaches
the middle of the sight glass.
To Drain Tank
NOTE: Operation of the air compres-
sor will cause condensation to build
up in the air tank. Always drain tank
on a washable surface or in a suit-
able container to prevent damaging
or staining surfaces.
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 con-
dense in the air
tank. If not drained, water will cor-
rode 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.

Air Filter - Inspection and
Replacement
Hot surfaces. Risk
of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
A dirty air filter will not allow the
compressor to operate at full capaci-
ty. 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.
Adjusting Belt Tension
1. Slide motor into original position,
line the motor up with the mark
made earlier on saddle.
2. Tighten two outside motor
mounting screws enough to hold
the motor in place for checking
pulley and flywheel alignment.
3. The belt should deflect 3/16" at
midway between the pulley and
the flywheel when a 5 pound
weight is applied at the midway
point.
4. When proper belt tension is
achieved, tighten all four motor
mounting screws. See Parts
manual for torque specifications.
NOTE: Once the engine pulley has
been moved from its factory set loca-
tion, the grooves of the flywheel and
pulley must be aligned to within 1/16"
to prevent excessive belt wear. Verify
the alignment by performing the fol-
lowing Pulley and Flywheel -
Alignment.
Belt - Replacement
(Refer to the Outfit Parts Manual
for replacement belt part number.)
Serious injury or
damage may
occur if parts of the body or loose
items get caught in moving parts.
Never operate the outfit with the
belt guard removed. The belt
guard should be removed only
when the AIR compressor power
is disconnected.
1. Turn air compressor off, lock
out the power supply, and
relieve all air pressure from the
air tank.
2. Remove the belt guard.
3. Mark pump position on saddle.
4. Loosen the motor mounting
screws and slide the motor
toward the air compressor.
5. Remove the belt and replace
with a new one.

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 air compressor off, lock out
the power supply, and relieve all
air pressure from the air tank.
2. Apply a soap solution to all air
line fittings and connections/pip-
ing.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can
cause the air compressor to over-
work, resulting in premature break-
down or inadequate performance.
Motor Pulley/Flywheel
Alignment
NOTE: Once the motor pulley has
been moved from its factory set loca-
tion, 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, per-
form the following steps:
1. Turn air compressor off, lock out
the power supply, and relieve all
air pressure from the air tank.
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. See Parts manual for
torque specifications.
Air compressor Head Bolts -
Torquing
The air compressor pump head bolts
should be kept properly torqued.
Check the torques of the head bolts
after the first five hours of operation.
Retighten if necessary. See Parts
manual for torque specifications.
7. Visually inspect the motor drive
pulley to verify that it is perpen-
dicular 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. See Parts manual for
torque specifications.
9. Reinstall belt guard.
