Power Tool-Specific Safety Warnings
▶ Safety Warnings Specific
for Grinding and Abrasive
Cutting-Off Operations
Use only wheel types that are recom-
mended 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 grinding surface of centre depressed
wheels must be mounted below the plane
of the guard lip. An improperly mounted
wheel that projects through the plane of
the guard lip cannot be adequately pro-
tected.
The guard must be securely attached to
the power tool and positioned for maxi-
mum safety, so the least amount of wheel
is exposed towards the operator. The
guard helps to protect operator from bro-
ken wheel fragments and accidental con-
tact with wheel.
Wheels must be used only for recom-
mended applications. For example: do
not grind with the side of 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 flang-
es support the wheel thus reducing the
possibility of wheel breakage. Flanges for
cut-off wheels may be different from grind-
ing wheel flanges.
Do not use worn down wheels from larg-
er power tools. Wheel intended for larger
power tool is 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. Over-
stressing 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 kick-
back may propel the spinning wheel and
the power tool directly at you.
When wheel is binding or when inter-
rupting 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 correc-
tive 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 work-
piece to minimize the risk of wheel pinch-
ing 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 ar-
eas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects
that can cause kickback.
Do not use type 1 abrasive wheels de-
signed for straight grinding.
Do not attempt to cut large stock or
sheets of metal as this machine is not de-
signed to be a dedicated cut-off machine.
▶ Safety Warnings Specific for
Sanding Operations
Do not use excessively oversized sand-
ing disc paper. Follow manufacturer’s
recommendations, when selecting sand-
ing paper. Larger sanding paper extending
beyond the sanding pad presents a lacera-
tion hazard and may cause snagging, tear-
ing of the disc or kickback.
