Important Safety Considerations

• DO NOT modify the tool in any way. Unauthorized modification may impair the function and/or safety of the tool and could affect the life of the tool. There are specific applications for which the tool is designed.
• Use the right tool for the job. DO NOT attempt to force a small piece of equipment to do the work of larger industrial equipment. There are certain applications for which this equipment was designed. It will do the job better and more safely at the capacity for which it was intended. DO NOT use this equipment for a purpose for which it was not intended.
• Industrial or commercial applications must follow OSHA requirements.

WARNING

WORK AREA SAFETY

• Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well lit. Cluttered, wet, or dark work areas can result in injury. Using the tool in confined work areas may put you dangerously close to other cutting tools and rotating parts.
•  Do not use the tool where there is a risk of causing a fire or an explosion; e.g., in the presence of flammable liquids, gases, or dust. The tool can create sparks, which may ignite dust or fumes.
• Do not allow the tool to come into contact with an electrical source. The tool is not insulated and contact will cause electrical shock.
• Keep children and bystanders away from the work area while operating the tool. Do not allow children to handle the tool.
• Be aware of all power lines, electrical circuits, water pipes, and other mechanical hazards in your work area. Some of these hazards may be below the work surface hidden from your view and may cause personal harm or property damage if unintentionally contacted.

PERSONAL SAFETY

• Stay alert, watch what you are doing, and use common sense when operating the tool. Do not use the tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the tool may result in serious personal injury.
• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Air vents on the tool often cover moving parts and should be avoided.
• Use safety apparel and equipment. Use ANSI-approved safety goggles or safety glasses with side shields, or when needed, a face shield. Use a dust mask in dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection systems, and hearing protection when appropriate. This applies to all persons in the work area.
•  Do not overreach. Keep proper footing and balance at all times.
• Remove adjusting keys or wrenches before connecting the tool to the air supply or turning on the tool. A wrench or key that is left attached to a rotating part of the tool may cause personal injury.
• Secure the work with clamps or a vise instead of your hand when practical. This safety precaution allows for proper tool operation using both hands.

CAUTION

TOOL USE AND CARE

• USE COMPRESSED AIR ONLY. Use clean, dry, and regulated compressed air to power the tool. Do not use oxygen, carbon dioxide, or any other bottled gas as a power source for this tool.

• Lubricate the tool before its initial use and before and after each additional use.

• Do not force the tool. Pneumatic tools do a better and safer job when used in the manner for
  which they are designed. Plan your work, and use the correct tool for the job.

• Check for damaged parts before each use. Carefully check that the tool will operate properly
  and perform its intended function. Replace damaged or worn parts immediately. Never operate the tool with a damaged part. · Do not use a tool with a malfunctioning switch. Any power tool that cannot be controlled with the power switch is dangerous and must be repaired by an authorized service representative before use.

• Disconnect the air supply from the tool and place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. · Store the tool when it is not in use. Store it in a dry, secure place out of the reach of children. Inspect the tool for good working condition prior to storage and before re-use. · Use only accessories that are recommended by the manufacturer for use with your tool. Accessories that may be suitable for one tool may create a risk of injury when used with another tool. Never use an accessory that has a lower operating speed or operating pressure than the tool itself. · Keep guards in place and in working order. Never operate the tool without the guards in place. · Do not leave the tool running unattended. · Inspect the tool, hose, and accessories for damage or excessive wear before each use. If you find damage do not use the tool.

To manually lubricate the tool, add a few drops of pneumatic tool oil to the tool’s airline connection.
