1. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its
own cord. Contact with a “live” wire will make exposed metal parts of tool “live” and shock the operator.
2. Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.
3. Keep hands away from all cutting edges and moving parts.
4. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a
MILWAUKEE
Service facility for a
free replacement.
5. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in
a well ventilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out
microscopic particles.
