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

• 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.

• 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.

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

HOW TO PREVENT IT

• 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.
• 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.

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.

• 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 filters 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 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
