wire is required. Always check that the power supply corresponds to
the voltage on the rating plate.
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 paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber. (CCA)
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.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the
skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse
dust, which may cause serious and permanent respiratory or
