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 equipment to do the work of larger industrial equipment. There are certain applications for which this equipment was designed.
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 the dust or fumes.
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.
