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.
• 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.
Direct particles away from face and body.
• Use the appropriate dust extractor vacuum to remove
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to the
operator and those in close proximity.
• Use clamps or other practical ways to secure and
support the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may lead
to loss of control and injury.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught in
moving parts.

CAUTION: When not in use, place tool on its side
on a stable surface where it will not cause a tripping
or falling hazard. Some tools with large battery packs
will stand upright on the battery pack but may be easily
knocked over.
