HAZARD

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.

4 - ENG

ATTACHMENTS & ACCESSORIES:

• Exceeding the pressure rating of air tools, spray
guns, air operated accessories, tires, and other
inflatables can cause them to explode or fly
apart, and could result in serious injury.

• Follow the equipment manufacturers
recommendation and never exceed the
maximum allowable pressure rating of
attachments. Never use compressor to inflate
small low pressure objects such as children’s
toys, footballs, basketballs, etc.

TIRES:

• Over inflation of tires could result in serious
injury and property damage.

• Use a tire pressure gauge to check the tires
pressure before each use and while inflating
tires; see the tire sidewall for the correct tire
pressure.

NOTE: Air tanks, compressors and similar

equipment used to inflate tires can fill small
tires very rapidly. Adjust pressure regulator on
air supply to no more than the rating of the
tire pressure. Add air in small increments and
frequently use the tire gauge to prevent over
inflation.

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 delivery.
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, CULUS, ETL®,

CETL, CETLUS, have been evaluated by OSHA certified independent safety laboratories and meet the
applicable 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 lower level the motor will restart automatically. The low pressure at which
the motor automatically restarts is called "cut-in" pressure.

7 - ENG

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 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.

DUTY CYCLE

This air compressor pump is capable of running continuously. However, to prolong the life of your air
compressor, it is recommended that a 50%-75% average duty cycle be maintained; that is, the air
compressor pump should not run more than 30-45 minutes in any given hour.

ASSEMBLY

UNPACKING

Remove unit from carton and discard all packaging.

INSTALLATION

HOW TO SET UP YOUR UNIT

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" (30.5 cm) away from the wall 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 (FIG. 1)

RISK OF ELECTRICAL SHOCK. In the event of a short circuit, grounding
reduces the risk 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

FIG. 1

having a grounding wire with an appropriate grounding
plug (A).

1. The cord set and plug (A) with this unit contains a

grounding pin (B). This plug MUST be used with a
grounded outlet (C).

IMPORTANT: The outlet being used must be installed
and grounded in accordance with all local codes and
ordinances.

2. Make sure the outlet being used has the same

configuration as the grounded plug. DO NOT USE AN ADAPTER. See figure 1.

3. Inspect the plug and cord before each use. Do not use if there are signs of damage.

4. If these grounding instructions are not completely understood, or if in doubt as to whether the

compressor is properly grounded, have the installation checked by a qualified electrician.

RISK OF ELECTRICAL SHOCK. IMPROPER GROUNDING CAN RESULT IN

ELECTRICAL SHOCK.
Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should

be installed by a qualified electrician.
Repairs to the cord set or plug MUST be made by a qualified electrician.

8 - ENG

EXTENSION CORDS

If an 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 will accept
the plug on the product

• in good condition

• no longer than 50' (15.2 m)

• 14 gauge (AWG) or larger. (Wire size increases as gauge number decreases. 12 AWG and 10AWG
may also be used. DO NOT USE 16 OR 18 AWG.)

Risk of Property Damage. The use of an undersized extension cord will cause
voltage to drop resulting in power loss to the motor and overheating. Instead of using an
extension cord, increase the working reach of the air hose by attaching another length of hose to its end.
Attach additional lengths of hose as needed.

VOLTAGE AND CIRCUIT PROTECTION

Refer to Specifications for the voltage and minimum branch circuit requirements.

Risk of Overheating. Certain 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 supply any other electrical needs.

3. Extension cords comply with specifications.

4. 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. Time

delay fuses should be marked "D" in Canada and "T" in the US.

Become familiar with these controls before operating the unit.
On(I)/Off(O) Switch (D): Place this switch in the On (I) position to provide automatic power to the

pressure switch and Off (O) to remove power at the end of each use.
Pressure Switch (not shown): 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 factory set "cut-out" pressure.

Safety Valve (H): 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 (I): The tank pressure gauge indicates the reserve air pressure in the tank.
Outlet Pressure Gauge (E): The outlet pressure gauge indicates the air pressure available at the outlet

side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the
tank pressure.

Regulator (G): Controls the air pressure shown on the outlet pressure gauge. Turn regulator knob
clockwise to increase pressure and counterclockwise to decrease pressure.

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.

Drain Valve (K): The drain valve is located at the base of the air tank and is used to drain condensation
at the end of each use.

K

FIG. 3 FIG. 4

Check Valve (not shown): 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.

Motor Overload Protector (not shown): The motor has a 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. Set the On/Off switch to "Off" and unplug unit.

2. Allow the motor to cool.

3. Plug the power cord into the correct branch circuit receptacle.

4. Set the Auto/Off switch to "On" position.
Motor Fuse Protector (not shown): The motor is provided with a fuse protector which may cause the

motor to shut off if motor current is too high. If the motor does not operate, follow the instructions under
Motor Overload Protector. If the motor fails to restart after following these instructions, return the unit
to a service center to have the fuse protector replaced. The fuse protector is not a customer serviceable
part.

Quick-Connect Body (F): The quick connect body accepts industrial quick connect plugs.
