Safety Warnings Specific for Wire
Brushing Operations
a ) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load to
the brush. The wire bristles can easily penetrate light
clothing and/or skin.
b ) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel or
brush may expand in diameter due to work load and
centrifugal forces.

Additional Safety Rules for Grinders

Do not use Type 11 (flaring cup) wheels on this tool.
Using inappropriate accessories can result in injury.
Always use side handle. Tighten the handle securely.
The side handle should always be used to maintain control
of the tool at all times.

WARNING: We recommend the use of a residual
current device with a residual current rating of 30mA
or less.

Additional Safety Information


WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,
NIOSH/OSHA/MSHA respiratory protection.

WARNING: 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 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.
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 disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection
36
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.

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.
Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught
in moving parts.
Do not operate this tool for long periods of time.
Vibration caused by tool action may be harmful to your
hands and arms. Use gloves to provide extra cushion and
limit exposure by taking frequent rest periods.
An extension cord must have adequate wire size
for safety. The smaller the gauge number of the wire,
the greater the capacity of the cable, that is, 16 gauge
has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension
to make up the total length, be sure each individual
extension contains at least the minimum wire size. The
following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use
the next heavier gauge. The lower the gauge number, the
heavier the cord.

representative or by an equally qualified person to
avoid danger.
