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 chemicalsare:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry 
products, and
• arsenic and chromium from chemically-treatedlumber.
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 microscopicparticles.
• 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 andbody.
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 hearingloss.
• 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 andbody.
• 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 closeproximity.
• 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 
movingparts.
• 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 thecord.

Lanyard Connection (Fig. B)
Safety Warnings Specific for Use At Height
WARNING: If the tool is dropped for any reason the 
lanyard connection must be inspected and properly serviced 
prior to re-use. The lanyard connection is designed to stretch 
to absorb the shock of a drop. Any permanent stretch to the
