1. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free
replacement.
2. 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 specially designed to filter out microscopic
particles.
3. 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 the tool live and shock the operator.
4. Keep hands away from all cutting edges and moving parts.
5. Wear ear protectors with impact drill. Exposure to noise can cause hearing loss.
6. Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
