4- ENG
1. RISK OF FIRE OR
EXPLOSION. Never
spray flammable
liquids in a confined
area. It is normal for the motor and
pressure switch to produce sparks while
operating. If sparks come into contact with
vapors from gasoline or other solvents,
they may ignite, causing fire or explosion.
Always operate the compressor in a well–
ventilated area. Do not smoke while
spraying. Do not spray where sparks or
flame are present. Keep compressor as far
from spray area as possible.
2. RISK OF BURSTING. Do not
weld, drill or modify the air tank
of this compressor. Welding or
modifications on the air
compressor tank can severely impair tank
strength and cause an extremely hazardous
condition. Welding or modifying the tank in
any manner will void the warranty.
3. RISK OF ELECTRICAL
SHOCK. Never use an electric
air compressor outdoors when
it is raining or on a wet surface,
as it may cause an electric shock.
4. RISK OF INJURY. This unit
starts automatically. ALWAYS
shut off the main power
disconnect, and bleed all
pressure from the system before servicing
the compressor, and when the compressor
is not in use. Do not use the unit with the
shrouds or belt guard removed. Serious
injury could occur from contact with
moving parts.
5. RISK OF BURSTING. Check
the manufacturer’s maximum
pressure rating for air tools and
accessories. Compressor outlet
pressure must be regulated so as to never
exceed the maximum pressure rating of the
tool. Relieve all pressure through the hose
before attaching or removing accessories.
6. RISK OF BURNS. High
temperatures are generated by
the pump and manifold. To
prevent burns or other injuries,
DO NOT touch the pump, manifold or
transfer tube while the pump is running.
Allow them to cool before handling or
servicing. Keep children away from the
compressor at all times.
7. RISK TO BREATHING. Be
certain to read all labels when
you are spraying paints or toxic
materials, and follow the safety
instructions. Use a respirator mask if there
is a chance of inhaling anything you are
spraying. Read all instructions and be sure
that your respirator mask will protect you.
Never directly inhale the compressed air
produced by a compressor. It is not
suitable for breathing purposes.
8. RISK OF EYE INJURY.
Always wear ANSI Z87.1
approved safety goggles when
using an air compressor. Never point any
nozzle or sprayer toward a person or any
part of the body. Equipment can cause
serious injury if the spray penetrates the
skin.
9. RISK OF BURSTING. Do not
adjust the relief valve for any
reason. Doing so voids all
warranties. The relief valve has
been pre-set at the factory for the
maximum pressure of this unit. Personal
injury and /or property damage may result if
the relief valve is tampered with.
10. RISK OF BURSTING.Do not
use plastic or pvc pipe for
compressed air. Use only
gavanized steel pipe and fittings
for compressed air distribution lines.
11. RISK OF BURSTING.Failure
to properly drain condensed
water from air tank, causing rust
and thinning of the steel air
tank.
Drain air tank daily or after each use. If
air tank develops a leak, replace it
WARNING

RISK OF BURSTING.
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety
Commission published Release # 02-108 concerning air compressor tank
safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent upon
several factors, some of which include operating conditions, ambient conditions, proper
installations, field modifications, and the level of maintenance. The exact effect of these
factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of
the air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized
air to suddenly and forcefully escape, posing risk of injury to consumers.
Your compressor air tank must be removed from service by the end of the year shown on
your tank warning label.
The following conditions could lead to a weakening of the air tank, and result in a violent
air tank explosion:
WHAT CAN HAPPEN HOW TO PREVENT IT
Failure to properly drain condensed water
from air tank, causing rust and thinning of
the steel air tank.
Drain air tank daily or after each use. If air
tank develops a leak, replace it immediately
with a new air tank or replace the entire
compressor.
Modifications or attempted repairs to the
air tank.
Never drill into, weld or make any
modifications to the air tank or its
attachments. Never attempt to repair a
damaged or leaking air tank. Replace with a
new air tank.
Unauthorized modifications to the safety
valve, or any other components which
control air tank pressure.
The air tank is designed to withstand
specific operating pressures. Never make
adjustments or parts substitutions to alter the
factory set operating pressures.
DANGER
1. Drain the moisture from the tank on a daily basis. A clean, dry tank will help
prevent corrosion.
2. Pull the pressure relief valve ring daily to ensure that the valve is functioning
properly, and to clear the valve of any possible obstructions.
WARNING
6- ENG
BASIC AIR COMPRESSOR COMPONENTS
The basic components of the air compressor are
the electric motor, pump, pressure switch and
tank (see Fig. 1). The tank may be vertical or
horizontal, varying in size and capacity.
The electric motor (see A) powers the pump.
The electric motor is equipped with an overload
protector to help prevent possible motor burnout.
If the motor becomes overheated, the overload
protector will shut it down. Should this occur,
allow the motor to cool for 10-15 minutes, then
press (never force) the motor reset switch to
restart the motor.
The pump (see B) compresses the air and
discharges it into the tank.
The tank (see C) stores the compressed air.
The pressure switch (see D) shuts down the
motor and relieves air pressure in the pump and
transfer tube when the air pressure in the tank
reaches the kick–out pressure. As compressed air
is used and the pressure level in the tank drops to
the kick–in pressure, the pressure switch restarts
the motor automatically, without warning and the
pump resumes compressing air.
The air line outlet (see E). Connect 1/4” NPT air hose to this outlet.

3. To provide proper ventilation for cooling, the compressor must be kept a
minimum of 12 inches (31 cm) from the nearest wall, in a well–ventilated area.
4. To prevent damage to tank and compressor on stationary models, the tank
must be shimmed so the pump base is level within 1/8” to distribute oil properly.
All feet must be supported, shimming where necessary, prior to attaching to the
floor. Fasten all feet to floor. We also recommend the use of vibration pads (094-
0137) under tank feet.
5. Fasten the compressor down securely if transporting is necessary. Pressure
must be released from the tank before transporting.
6. Protect the air hose from damage and puncture. Inspect them weekly for weak
or worn spots, and replace if necessary.
7. To reduce the risk of electric shock, do not expose to rain. Store indoors.
7 - ENG
ASSEMBLING THE COMPRESSOR
1. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged
in transit, contact the carrier and complete a damage claim. Do this immediately
because there are time limitations to damage claims.
The carton should contain:
air compressor
operator and parts manuals
2. Check the compressor’s serial label to ensure that you have received the model
ordered, and that it has the required pressure rating for its intended use.
3. Locate the compressor according to the following guidelines:
a. For optimum performance, locate the compressor close to the power panel, as
specified in ELECTRICAL POWER REQUIREMENTS, and as close as possible
to the place where the air will be used. This ensures maximum power to the
compressor and maximum air pressure to the tool. If both of these conditions
cannot be met, it is better to locate the compressor close to the power panel,
and use a longer air hose to reach the usage area.
b. The flywheel side of the compressor must be at least 12 inches (31 cm) from any
wall or obstruction, in a clean, well-ventilated area, to ensure sufficient air
flow and cooling.
c. In cold climates, locate the compressors in a heated building when not in use.
This will reduce problems with lubrication, motor starting and freezing of water
condensation.
d. Remove the compressor from the shipping pallet and place it on the floor or a
hard, level surface. The compressor must be level to ensure proper
lubrication of the pump and good drainage of the moisture in the tank.
Risk of injury: The shipping pallet is not designed as a base for
an operating compressor. Operating the compressor while it is on the pallet will
void your warranty.
e. To prevent damage to tank and pump, the tank must be shimmed so the pump
is level within 1/8” per lineal foot maximum to distribute oil properly. Fasten to
floor and NEVER force tank feet to floor without shims when tightening. We also
recommend the use of vibration pads (094-0137) under tank feet (C).
4. Connect an air hose (not included) to the
compressor.

9 - ENG
TYPICAL INSTALLATION
AIR DRYERS AND AFTER COOLERS
An air dryer or aftercooler is installed directly in the air line.
MOISTURE REMOVAL AND AIR FILTRATION
As the air cools, moisture will condense in the lines. This moisture
must be removed before it reaches the tool being used. To remove this
moisture, run the main air line downhill to a moisture trap and drain. Air/
water filters should also be installed in the positions shown.
AIR PRESSURE REGULATION
Install an air regulator in the drop line for each tool, to regulate air
pressure to that tool. Never exceed the maximum pressure rating of the
tool.
AIR LUBRICATION
Install an air lubricator only for those tools requiring lubrication. Do not
use a lubricator for paint spraying or similar applications. The oil will
contaminate the paint and ruin the job.
SHUT–OFF VALVES
Install shut–off valves in each drop line, to isolate the tool and its
accessories for servicing. You can also install a bypass line around an
accessory.
10- ENG
COMPRESSOR CONTROLS
Refer to Fig. 3.
PRESSURE switch (see A)
This switch turns on the compressor. It is operated manually, but when in the
AUTO position, it allows the compressor to start up or shut down automatically,
without warning, upon air demand. ALWAYS set this switch to OFF when the
compressor is not being used, and before unplugging the compressor.
Pressure Relief Valve (see B)
If the pressure switch does not shut down the motor when pressure reaches
the preset level, this valve will pop open automatically to prevent over
pressurization. To operate manually, pull the ring on the valve to relieve air
pressure in the tank.
Tank Pressure Gauge (see C)
This gauge measures the pressure level of the air stored in the tank. It is not
adjustable by the operator, and does not indicate line pressure.
NOTE: Not all models are equipped with the following:
Fig. 3
11 - ENG
ELECTRICAL POWER REQUIREMENTS
I WARNING
Risk of electrical shock. Improper electrical grounding
can result in electrical shock. The wiring should be done by a qualified
electrician.
ELECTRICAL WIRING
Refer to the air compressor’s serial label for the unit’s voltage and amperage
requirements. Ensure that all wiring is done by a licensed electrician, in
accordance with the National Electrical Code..
MAIN POWER PANEL
For best performance and reliable starting, the air compressor must be installed
on a dedicated circuit, as close as possible to the electrical power panel.
Provide circuit breaker or fuse protection at your main power panel. Use time
delay fuses on the circuit, because the compressor will momentarily draw
several times its specified amperage when first started.
NOTE: A circuit breaker is recommended. If the air compressor is connected to
a circuit protected by a fuse, use dual element time delay fuses (Buss Fusetron
type “T” only).
MAIN POWER DISCONNECT SWITCH
Install a main power disconnect switch in the line from the panel to the
compressor. The main power disconnect switch must be located near the
compressor, for ease of use and safety. When turned OFF, the main power
disconnect switch shuts off all power to the compressor. When it is turned ON,
the compressor will start and stop automatically, controlled by the pressure
switch.
LOW VOLTAGE PROBLEMS
Low voltage will cause difficult starting or an overload. Low voltage can be
caused by a low supply voltage from the local power company, other equipment
running on the same line, or inadequate wiring. If any other electrical devices are
drawing from the compressor’s circuit, it may fail to start.
Low voltage to the compressor can be caused by a supply wire of insufficient
gauge for the distance between the compressor and the power source. The
longer the distance, the larger the wire gauge (lower the number) must be, to
overcome the inherent voltage loss caused by the wire resistance. Refer to the
National Electrical Code to determine proper wire size for your circuit.
If the wiring is not adequate, the input voltage will drop by 20 to 40 volts at
startup. Low voltage or an overloaded circuit can result in sluggish starting that
causes the circuit breaker to trip, especially in cold conditions.
GROUNDING INSTRUCTIONS
This product must be connected to a grounded, metallic, permanent wiring
system, or an equipment - grounding terminal or lead on the product.
12- ENG
MOTOR RESET SWITCH AND WIRING
Ensure that all guards and shrouds are in place before
pressing the reset switch to restart the motor.
If the motor shuts down because of overload, wait 10–15 minutes so the motor
can cool down, then press (NEVER force) the reset switch (see A) to restart the
motor (see Fig. 5).
Note: On stationary models not supplied with a power cord, the electrical power
must be wired into the pressure switch by a Licensed Electrician.
I WARNING
OPERATING INSTRUCTIONS
BREAK-IN OF THE PUMP (Fig. 6)
1. Make sure the power is connected at the power panel.
2. Check the oil level in the pump (see “Checking the Oil” in the maintenance
section).
3. Open the petcock (see F).
Escaping air and moisture can propel debris that
may cause eye injury. Wear safety goggles when opening petcock.
4. Turn ON the main power disconnect switch. Turn the pressure switch to the
AUTO position (see D). The motor should start. Allow the compressor to run
for 30 minutes, to break in the internal parts.
NOTE: After about 30 minutes, if the unit does not operate properly, SHUT
DOWN IMMEDIATELY, and contact a qualified service center. DO NOT
return the unit to the store where it was purchased.
5. Shut OFF the main power disconnect. Close the petcock (see E). Connect
your air hose(s) to the tank outlet(s).

MAINTENANCE
MAINTENANCE
To avoid personal injury, always shut off and unplug the
compressor and relieve all air pressure from the system
before performing any service on the air compressor.
Regular maintenance will ensure trouble–free operation. Your electric powered
air compressor represents high–quality engineering and construction; however,
even high–quality machinery requires periodic maintenance. The items listed
below should be inspected on a regular basis
DRAINING THE TANK (Fig. 6)
Condensation will accumulate in the tank. To
prevent corrosion of the tank from the inside, this moisture must
be drained at the end of every workday.
I WARNING
Be sure to wear protective eyewear. Relieve the
air pressure in the system and open the petcock on the bottom of
the tank to drain.
CHECKING THE OIL
Check the level of oil in the pump with the sight glass. The pump oil level must
be between A and B (See Fig. 7). Do not overfill or underfill.
NOTE: Use synthetic blend, non-detergent air compressor oil.
CHANGING THE OIL
Remove the oil plug (C) (Fig. 7) and drain the oil until it slows to a drip, then
close. Add oil to the pump by first removing the breather plug (E). Add oil until
the level viewed through the sight glass (D) is between FULL (A) and ADD (B).
Never overfill or underfill the pump.

BELT TENSION AND PULLEY ALIGNMENT
To avoid personal injury, always shut off and unplug the
compressor and relieve all air pressure from the system before performing
any service on the air compressor.
NOTE: Drive belt tensioning and pulley alignment are done at the same time.
They are discussed separately for clarity.
ADJUSTING DRIVE BELT TENSION
Proper belt tension and pulley alignment must be maintained for maximum drive
efficiency and belt life. The correct tension exists if a deflection (see A) of 1/2”
(13 mm) occurs by placing 5 lb (2.3 kg) of force (see B) midway between the
motor pulley and the pump flywheel (See Fig. 8). This deflection can be adjusted
by the following procedure. The pulley should be carefully aligned with the
flywheel, and all setscrews should be kept tight.
1. Remove the belt guard.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct deflection exists.
4. Retighten the motor mounting bolts.
5. Check to ensure that the tension remained correct.
6. Reinstall the belt guard. All moving parts must be guarded.
I WARNING

MAINTENANCE
17 - ENG
PULLEY ALIGNMENT
To check pulley alignment, remove the belt guard and place a straightedge
(see A) against the pump flywheel (see B) (See Fig. 9). Measure and record the
distance from the straightedge to the edge of the drive belt at point C. Then
measure the distance from the straightedge to the edge of the drive belt again
at points D and E. Both distances should be the same as at point C. If D or E
are different from C, there is a misalignment which must be corrected before
the compressor is run. To correct a pulley misalignment, use the following
procedure.
1. Remove the belt guard.
2. Loosen the motor mounting bolts.
3. Loosen the setscrew on the motor pulley.
4. Align the motor pulley with the pump flywheel (C = D = E).
5. Retighten the motor pulley setscrew.
6. Adjust the proper belt tension.
7. Retighten the motor mounting bolts.
8. Reinstall the belt guard. All moving parts must be guarded.

SERVICE INTERVAL
CLEANING THE AIR FILTER
A dirty air filter will reduce the compressor’s performance and life. To avoid
any internal contamination of the pump, the filter should be cleaned frequently,
and replaced on a regular basis. Felt filters should be cleaned in warm, soapy
water, rinsed, and allowed to air dry before reinstallation. Paper filters should be
replaced when dirty. Do not allow the filter to become filled with dirt or paint. If
the filter becomes filled with paint, it should be replaced. Direct exposure to dirty
conditions or painting areas will void your warranty.
CHECKING THE RELIEF VALVE
Pull the relief valve daily to ensure that it is operating properly and to clear the
valve of any possible obstructions.
TESTING FOR LEAKS
Check that all connections are tight. A small leak in any of the hoses, transfer
tubes, or pipe connections will substantially reduce the performance of your air
compressor. If you suspect a leak, spray a small amount of soapy water around
the area of the suspected leak with a spray bottle. If bubbles appear, repair or
replace the faulty component. Do not overtighten any connections.
STORAGE
Before storing the compressor for a prolonged period, use an air blow gun to
clean all dust and debris from the compressor. Disconnect the power cord and
coil it up. Pull the pressure relief valve to release all pressure from the tank. Drain
all moisture from the tank. Clean the filter element and filter housing; replace the
element if necessary. Drain the oil from the pump crankcase and replace it with
new oil. Cover the entire unit to protect it from moisture and dust.
