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 causes 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.
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 part 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.

· Locate the air compressor at least 12″ (30.5 cm) away from the wall or other obstructions 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. 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 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

12

English

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.
Electrical Wiring
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.
Refer to the air compressor’s specification label for the unit’s voltage and amperage requirements. For best performance and reliable starting, the air compressor must be plugged into a dedicated circuit, as close as possible to the fuse box or circuit breaker. The compressor will use the full capacity of a typical 15 amp household circuit. If any other electrical devices are drawing from the compressor’s circuit, the compressor may fail to start. Low voltage or an overloaded circuit can result in sluggish starting that causes the motor overload protection system or circuit breaker to trip, especially in cold conditions. NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use only time delay fuses.
WARNING: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.
