grinding disc, grinding plate,
wire brush etc. Chopping or
blocking leads to sudden stop-
ping of the rotating attachment.
This causes an uncontrolled elec-
tric tool to accelerate in a direc-
tion counter to the rotational di-
rection of the attachment tool. If,
for example, a grinding disc cuts
into the workpiece or blocks it,
the edge of the grinding disc that
digs into the workpiece can get
caught and, through that, break
off the grinding disc or cause a
kickback. The grinding disc then
moves towards or away from
the operator, depending on the
direction of rotation of the disc
at the blocked spot. Here, the
grinding discs can also break. A
kickback is caused by wrongly
or incorrectly operating the elec-
tric tool. It can be avoided by
suitable cautionary measures,
such as described below.
a)
Hold the electric tool very
firmly and bring your body
and your arm into a position
in which you can resist the
kickback force. Always use
the supplemental handle if
available to give you the best
control over kickback force or
reaction time during accelera-
tion.
The operator can master
the kickback and reaction
force through suitable precau-
tions.
b)
Never bring your hands near
a rotating attachment tool.
The attachment tool can run
over your hand in the kick-
back.
c)
Keep your body away from
the area in which the electric
tool would move during a
kickback.
The kickback drives
the electric tool in the counter-
direction to the rotation of the
grinding disc at the blocked
spot.
d)
Work particularly cautious-
ly in corner areas or where
there are sharp corners etc.
Prevent the attachment tools
from recoiling from the work-
piece and jamming. The ro-
tating attachment tool tends
to jam when near corners,
sharp edges or when it recoils
from such.
This causes a loss
of control or kickback.
e)
Do not use chain or toothed
saw blades.
Such attachment
tools frequently cause a kick
-
back or loss of control over
the electric tool.
Special safety instructions
for grinding and cutting
a)
Use only grinders which have
been approved for your elec-
tric tool and the protective
hood intended for these grin-
ders.
Grinders which are not
intended for the electric tool
may not be sufficiently shiel
-
ded and are unsafe.
b)
Depressed Center grinding
wheels must be pre-assem-
bled so that their surface not
above the level of the edge
of the guard stands out.

wheel, which extends beyond
