your hand, the possible kickback may propel
the spinning wheel and the power tool directly
at you.
When wheel is pinched, snagged 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 pinching or
snagging.
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.
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.
GFCI and personal protection devices like
electrician's rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the tool since internal wires may be
misplaced or pinched or safety guard return
springs may be improperly mounted.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Ensure the switch is in the off position
before inserting battery pack. Inserting the
battery pack into power tools that have the
switch on invites accidents.

Additional Safety Warnings

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 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.
Allow brushes to run at operating speed for
at least one minute before using them.
During this time no one is to stand in front
or in line with the brush. Loose bristles or
wires will be discharged during the run-in time.
Direct the discharge of the spinning wire
brush away from you. Small particles and tiny
wire fragments may be discharged at high
velocity during the use of these brushes and
may become imbedded in your skin.
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.
