The air stream may contain carbon monoxide or other vapors, or particles from the tank or other components. • Sprayed materials such as paint, paint solvents, paint remover, insecticides, weed killers, etc., contain harmful vapors and poisons. • Breathing compressor or sprayed materials vapor can result in serious injury. HOW TO PREVENT IT • Never inhale air from the compressor, either directly or from a breathing device connected to the compressor. Work in an area equipped with good cross ventilation. • Read and follow the safety instructions provided on the label or safety data sheet for the material you are spraying. Use an approved respirator designed for use with your specific application. WARNING Risk from Compressed Air WHAT CAN HAPPEN The compressed air stream can cause soft tissue damage, and can propel dirt, chips, loose particles and small objects at high speed, resulting in property damage or personal injury. HOW TO PREVENT IT • Always wear approved safety glasses with side shields when using or maintaining the compressor. • Never point any nozzle or sprayer toward any part of the body or at other people or animals. • Always turn the compressor off and bleed pressure from the air line before attempting maintenance, attaching tools or accessories. WARNING Risk from Moving Parts WHAT CAN HAPPEN The compressor cycles automatically when the pressure switch is in the on/auto position. If you attempt repair or maintenance while the compressor is operating or plugged in, you can expose yourself to moving parts. These moving parts can cause serious injury. HOW TO PREVENT IT • Always unplug the compressor and release air pressure from the tank and any attachments before attempting any maintenance or repair. • Never operate the compressor with guards or covers which are damaged or removed. • Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. • Air vents may cover moving parts and should be avoided as well. WARNING Risk of Burn WHAT CAN HAPPEN Contact with hot parts such as the compressor head or outlet tubes could result in a serious skin burn. 4 HOW TO PREVENT IT • Never touch hot components during or immediately after operation of the compressor. Do not reach around protective shrouds or attempt maintenance until unit has been allowed to cool. GLOSSARY 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. CUT-IN PRESSURE: While the motor is off, air tank pressure drops as you continue to use your accessory or air tool. When the tank pressure drops to a certain level the motor will restart automatically re-started is called "cut-in pressure". CUT-OUT PRESSURE: When you turn on your air compressor, it begins to run, air pressure in the air tank begins to build. It builds to a certain pressure before the motor automatically shuts off - protecting your air tank from pressure higher than its design rating. The pressure at which the motor shuts off is called "cut-out pressure". DUTY CYCLE All Makita manufactured air compressors are recommended to be operated on not more than a 50% duty cycle. This means an air compressor that pumps air more than 50% in one hour is considered misuse because the air compressor is undersized for the required air demand. GENERAL INFORMATION This air compressor is equipped with an Oil-Less pump designed for durability and no maintenance. The compressor can be used for properly rated pneumatic nailers and staplers. An air pressure regulator is supplied for these applications. WARNING Never use compressor for applications other than to operate a properly rated nailer or stapler. Use of the compressor for other applications could result in property damage and personal injury. Separate air transformers which combine the functions of air regulation and/or moisture and dirt removal should be used where applicable. ON-RECEIPT INSPECTION DAMAGE: Each air compressor outfit is carefully tested and checked before shipment. With improper handling, damage may result in transit and cause problems with compressor operation. Immediately upon arrival, check equipment for both concealed and visible damages to avoid expenses being incurred to correct such problems. This should be done regardless of any visible signs of damage to the shipping container. If this product was shipped directly to you, report any damages to the carrier and arrange for inspection of goods immediately.
