Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations:
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.
Do not position your body in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
your body, the possible kickback may propel
the spinning wheel and the power tool directly
at you.
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.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
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.
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.
Always use type 1 cutting guard for cutting
operations. Other guards or attachments may
not protect operator in the event of a wheel
burst.
Do not attempt to cut large stock or sheets
of metal as this machine is not designed to
be a dedicated cut-off machine. Large
materials shift while cutting and cause wheel to
burst.
Safety Warnings Specific for
Sanding Operations:
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.
A guard may not be used for all sanding
operations. Do not discard guard when not
in use. Use hand shield when sanding without
a guard. Always reinstall wheel guard when
converting back to grinding operations.
Safety Warnings Specific for
Wire Brushing Operations:
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.
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.
A guard may not be used for all wire
brushing operations. Do not discard guard
when not in use. Use hand shield when
brushing without a guard. Always reinstall
wheel guard when converting back to grinding
operations.
Do not use a knotted wire brush with this
tool. This tool does not have a guard for
knotted brushes.
Additional Warnings:
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known 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.
