DANGER: 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.

• Modifications or attempted repairs to the 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.

• 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.

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.

Tires:

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

• The air tank is designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures.

• 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.

• 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.

Lubrication and Oil

AIR COMPRESSOR

The air compressor pump was filled WITH oil at the manufacturer. Check air compressor pump oil level before operating unit. See

Compressor Pump Oil under Maintenance.

Compatibility

Air tools and accessories that are run off the compressor must be compatible with petroleum based products. If you suspect that a material is not compatible with petroleum products, an air line filter for removal of moisture and oil vapor in compressed air is required.

NOTE: Always use an air line filter to remove moisture and oil vapor when spraying paint.

Location

• Locate the air compressor in a clean, dry, and well ventilated area.

• Located the air compressor at least 12” (30.5 cm) away from the wall or other obstructions that will interfere with the flow of air.

English

• Locate the air compressor as close to the main power supply as possible to avoid using long lengths of electrical wiring. NOTE: 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.

HUMID AREAS

English

In frequently humid areas, moisture may form in the pump and produce sludge in the oil, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes. Two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in compressor oil. You may be able to prevent moisture from forming in the pump by increasing ventilation or operating for longer intervals.

Wiring Instructions

WARNING: 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 electrician who is familiar with the current national electrical code and any prevailing local electrical codes.

WARNING: 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 Specifications, 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 used must be rated for 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.

WARNING: Risk of electrical shock. Electrical wiring must

be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.

Grounding Instructions

WARNING: 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 having a grounding wire with an appropriate grounding plug.

1. The cord set and plug (R) with this unit contains a grounding pin (P). This plug MUST be used with a grounded outlet (Q).

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

2. Ensure the outlet being used has the same configuration as the grounded plug. DO NOT USE AN ADAPTER.

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.

DANGER: 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.

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

• plug is not worn

• no longer than 50 feet (15.2 m)

• 12 gauge (AWG) or larger. (Wire size increases as gauge number decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.)

NOTICE: 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. Always use a minimum 3/8” (9.5 mm) or greater air hose rated at 300 psi.

Voltage and Circuit Protection

Refer to the Voltage and Minimum Branch Circuit Requirements under Specifications.

CAUTION: Certain air compressors can be operated on a

15 amp circuit if the following conditions are met.

• Voltage supply to circuit must comply with the National Electrical Code.

• Circuit is not used to supply any other electrical needs.

• Extension cords comply with specifications.

• 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 U.S.

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. It is not necessary to change the cord set.

2. Remove the belt guard by removing the 5 screws (X) using a Phillips head screwdriver.

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.

6. See the Adjusting Belt Tension before tightening motor mounting screws.

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 1/2” (13 mm)at midway between the pulley and the flywheel when a 5 pound (2.26 kg.) weight is applied at the midway point.

3. When proper belt tension is achieved, tighten all

four motor mounting screws. Torque to 20-25 ft-lbs (27.1–33.9 Nm).

NOTE: Once the engine pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16” (1.6mm) to prevent excessive belt wear. Verify the alignment by performing the following Motor Pulley/

Flywheel - Alignment.

Downward Force

Deflection

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” (1.6 mm) to prevent excessive belt wear.

The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16” (1.6 mm) to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps:

1. Set the Auto/Off lever to “Off”, unplug the unit, 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” (1.6 mm).

5. If the difference is greater than 1/16” (1.6 mm) 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” (1.6 mm) of each other.

6. Tighten the motor drive pulley set screw.

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. Torque to 145–165 in lbs (16.4–20.3Nm).

9. Reinstall belt guard.

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. Set the Auto/Off lever to “Off”, unplug the unit, and relieve all air pressure from the air tank.

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
