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.

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.
• 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.
• Do not use Type 11 (flaring cup) wheels on this tool.
Using inappropriate accessories can result in injury.
• Always use auxiliary handle. Tighten the handle securely.
The auxiliary handle should always be used to maintain
control of the tool at all times.
• When starting the tool with a new or replacement
wheel, or a new or replacement wire brush installed,
hold the tool in a well protected area and let it run for
one minute. If the wheel has an undetected crack or flaw,
it should burst in less than one minute. If the wire brush has
loose wires, they will be detected. Never start the tool with a
person in line with the wheel. This includes the operator.
• To prevent the spindle end from contacting the
bottom of the hole of the hubbed wheel, use accessories
that have a threaded hole depth of at least 21 mm.
Failure to use an accessory with the appropriate thread depth
could result in damage to the hubbed wheel and injury to the
operator or persons in the area.
• Avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the wheel
for cracks or flaws.
• Always handle and store wheels in a careful manner.
• Do not operate this tool for long periods of time.
Vibration caused by the operating action of this tool may
cause permanent injury to fingers, hands, and arms. Use
gloves to provide extra cushion, take frequent rest periods, and
limit daily time of use.
• Safety goggles or safety glasses with side shields and
a full face shield compliant with ANSI Z87.1 MUST be
worn by the operator and others that are within 50'
(15.2 m) of the use of this product.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught in
moving parts.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) 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.
