Warning Information
Parts Breakdown
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 paints,
• 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.
