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 disperse dust,
which may cause serious and permanent respiratory or other
injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
WARNING: Always wear proper personal hearing protection
that conforms to ANSI S12.6 (S3.19) during use. Under some
conditions and duration of use, noise from this product may
contribute to hearing loss.
WARNING: When not in use, place grinder on a stable
surface where it will not move inadvertantly, roll or cause a
tripping or falling hazard. Serious personal injury may result.
WARNING: The grinding wheel or accessory may loosen
during coast-down of the tool when shut off. If grinding wheel or
accessory loosens, it may dismount from the machine and may cause
serious personal injury.
CAUTION: To reduce the risk of personal injury, use extra care
when working into a corner or edge because a sudden, sharp
movement of the tool may be experienced when the wheel or other
accessory contacts a secondary surface or a surface edge.
