Operating instructions
b) Never place your hand near the rotating
accessory. The accessory may kickback
over your hand.
c) Do not position your body in the area
where the power tool will move if
kickback occurs. Kickback will propel the
tool in the direction opposite to the wheel's
movement at the point of snagging.
d) Use special care when working corners,
sharp edges, etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of control
over the power tool.
Additional safety instructions for grind-
ing and cutting off operations
a) Always use guard designed for the type of
wheel you are using. 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.
b) 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.
c) 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.
d) 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.

e) 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
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) 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.
g) 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.
