.
accumulation of metallic dust can cause
electrical hazards.
q. Do not use the electric power tool in
the vicinity of flammable materials.
Sparks can ignite such materials.
r. Do not use any tool inserts which
require liquid coolants. The use of water
or other liquid coolants could result in
electrical shock.
FURTHER SAFETY INSTRUCTIONS FOR
CUT OFF GRINDING APPLICATIONS
Kickback and relevant safety
instructions
• Kickback is the sudden reaction following
snagging or jamming of a rotating grinding
disc. Snagging or jamming lead to an
abrupt stop of the rotating tool insert. This
may then cause the uncontrolled electric
power tool to accelerate in the opposite
direction to the inserted tools direction of
rotation at the point were it jammed.
• If, for example, a grinding disc snags or
jams inside a workpiece, the edge of the
grinding disc which is inside the workpiece
may become caught and thus cause the
grinding disc to jump out or create a kick-
back. The grinding disc then moves
towards or away from the operator,
depending on the direction of rotation of
the disc at the jamming point. This can
also cause a grinding disc to break.
• A kickback is the result of improper or
incorrect use of the electric Power tool. It
can be avoided by taking suitable precau-
tions, as described below.
a. Hold the electric power tool firmly and
place your body and arms in such a
position that you can absorb the force
of a kickback. Always use the auxiliary
grips, when available, in order to have
the greatest possible control over kick-
back forces or torque reactions at high
speed. By taking suitable precautionary
measures, the operator can control kick-
back and reaction forces.
b. Never bring your hand into the vicinity
of a rotating tool insert. The inserted
tool could move over your hand if kick-
back occurs.
c. Avoid the area in front of and behind a
rotating cutting wheel. A kickback will
send the electric power tool in the oppo-
site direction to the movement of the
grinding disc at the point where it jams.
d. Work extremely carefully in the neigh-
bourhood of corners, sharp edges etc.
Prevent the tool insert from recoiling
from the workpiece and jamming. The
rotating tool insert bends at corners and
sharp edges or if it rebounds and may
jam itself. This causes a loss of control
or kickback.
e. Do not use any chainsaw or toothed
saw blade, nor any segmented dia-
mond disc, with slots wider than 10
mm. Such tool inserts frequently cause a
kickback or loss of control of the electric
power tool.
f. Avoid jamming of the cutting wheel or
too high a contact pressure. Do not
make excessively deep cuts. An over-
load of the cutting wheel increases its
stress and its susceptibility to tilting or
jamming and, hence, increases the pos-
sibility of a kickback or break in the
grinding wheel.
g. If the cutting wheel becomes jammed
or if you interrupt the work, switch the
device off and keep it held gently until
the disc has come to a standstill. Never
attempt to remove a still-running cutting
wheel from the cut, otherwise kickback
may result. Find and remove the cause
for the jamming.
h. Do not switch on the electric power
tool again, while it is still in the work-
piece. Allow the cutting wheel to first
reach its full rotation speed before care-
fully continuing the cut; otherwise, the
disc may snag, jump out of the work-
piece or cause a kickback.
i. Provide support for large workpieces,
to reduce the risk of a kickback
through jamming of the cutting wheel.
Large workpieces can bend under their
own weight. The workpiece must be
supported on both sides of the disc, as
well as both in the neighbourhood of the
separation cut and at the edges.
