Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations
a ) Do not "jam" the cut‑off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheel breakage.
b ) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point
of operations, is moving away from your body, the
possible kickback may propel the spinning wheel and
the power tool directly at you.
c ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut‑off wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of
wheel binding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re‑enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
e ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece
on both sides of the wheel.
f ) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding
Operations
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer's recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc or kickback.
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 llight
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 and
centrifugal forces.

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

WARNING: Never modify the power tool or any part of
it. Damage or personal injury could result.

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.

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
