Safety warnings specific for grinding and
abrasive cutting off operations
Always use the guard designed for the type
of wheel you are using. The guard must be
securely attached to the power tool and po-
sitioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. The guard helps to protect the oper-
ator from broken wheel fragments and acci-
dental contact with the wheel.
Use only wheel types that are recom-
mended for your power tool and the spe-
cific guard designed for the selected
wheel. Wheels for which the power tool was
not designed cannot be adequately guarded
and are unsafe.
Wheels must be used only for recom-
mended applications. For example: Do not
grind with the side of a cut-off wheel. Abrasive
cut-off wheels are intended for peripheral
grinding; side forces applied to these wheels
may cause them to shatter.
Always use undamaged wheel flanges that
are of correct size and shape for your se-
lected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of
wheel breakage. Flanges for cut-off wheels
may be different from grinding wheel flanges.
Do not use worn down wheels from larger
power tools. A wheel intended for a larger
power tool is not suitable for the higher speed
of a smaller tool and may burst.
Additional safety warnings specific for abra-
sive cutting off operations
Do not "jam" the cut-off wheel or apply ex-
cessive 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 break-
age.
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 the wheel is binding or when inter-
rupting a cut for any reason, switch off the
power tool and hold the power tool motion-
less until the wheel comes to a complete
stop. Never attempt to remove the cut-off
wheel from the cut while the wheel is in mo-
tion, otherwise kickback may occur. Inves-
tigate 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 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 un-
der 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.
Safety warnings specific for sanding opera-
tions
When sanding, do not use excessively
oversized sanding disc paper. Follow the
manufacturers' recommendations when
selecting sanding paper. Larger sanding pa-
per extending beyond the sanding pad
presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety warnings specific for polishing opera-
tions
Do not allow any loose portion of the pol-
ishing bonnet or its attachment strings to
spin freely. Tuck away or trim any loose at-
tachment strings. Loose and spinning attach-
ment strings can entangle your fingers or snag
on the workpiece.
