IMPORTANT SAFETY INSTRUCTIONS

Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals

known (to the State of California) to cause cancer, birth defects or other
reproductive harm. Some example of these chemicals are:

lead from lead-based paints

crystalline silica from bricks and cement and other masonry products

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, always wear

MSHA/NIOSH

approved, properly fitting face mask or respirator when using

such tools.

When using air tools, basic safety precautions should always be followed to
reduce the risk of of personal injury.
