Additional safety instructions for
grinding and cutting off operations
Use only wheel types that are recommended
for your power tool and the specific
guard designed for the selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
The guard must be securely attached to the
power tool and positioned for maximum
safety, so the least amount of wheel is exposed
towards the operator. The guard helps to protect
operator from broken wheel fragments and
accidental contact with wheel.
Wheels must be used only for recommended
applications. For example: do not grind
with the side of the 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 selected
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. Wheels intended for larger
power tools are not suitable for the higher
speed of a smaller tool and may burst.
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.
Safety warnings specific for sanding
operations
Do not use excessively oversized sanding
disc paper. Follow manufacturers
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
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.
