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 us-
ing such tools.

GENERAL SAFETY RULES
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power
tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a polarized outlet. Do not change the
plug in any way. Double Insulation eliminates the need for the three wire
grounded power cord and grounded power supply system.
2. Avoid body contact with grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your
body is grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the
plug from an outlet. Keep cord away from heat, oil, sharp edges or moving
parts. Replace damaged cords immediately. Damaged cords increase the risk
of electric shock.
