Safety advice
relating to kickback
Kickback is the sudden reaction to a pinched or
snagged rotating attachment, such as a grinding
disc, grinding pad, wire brush etc. Pinching or
snagging results in the rotating attachment coming
to an abrupt stop. This causes the electrical power
tool (if not controlled) to move in the opposite di-
rection to the direction of rotation of the attachment
at the point of constraint.
If, for example, a grinding disc is pinched or snags
in a workpiece, this can cause the edge of the
grinding disc to penetrate the workpiece, become
trapped there and either free itself or kickback. The
grinding disc moves towards or away from the op-
erator, depending on the direction of movement of
the disc at the point of constraint. The grinding disc
could also break.
Kickback occurs as a result of incorrect use or misuse
of the electrical power tool. It can be prevented by
taking the appropriate precautions as described below.
a) Maintain a firm grip on the electrical
power tool and position your body
and arms to allow you to resist kick-
back forces. Always use the auxiliary
handle, if provided, to exercise the
greatest possible control over kick-
back forces or reaction torques as the
device builds up to full speed. By taking
suitable precautions the operator can control
kickback and reaction forces.
b) Do not place your hands near a rotat-
ing attachment. If kickback occurs the at-
tachment could move over your hand.
c) Avoid positioning your body in the
area into which the electrical power
tool would move in the event of a
kickback. A kickback moves the electrical
power tool in the opposite direction to the di-
rection of movement of the grinding disc at the
point of constraint.
d) Work particularly carefully in the
area of corners, sharp edges etc. to
avoid the attachment bouncing or
snagging on the workpiece. Corners,
sharp edges or bouncing have a tendency to
snag the rotating attachment. This causes loss
of control or kickback.
e) Do not use saw-chain woodcarving
discs or toothed discs. Such attachments
create frequent kickback and loss of control of
the electrical power tool.
Q
Special safety advice relating
to grinding and disc-cutting
a) Always use the guard designed for
the type of abrasive consumable you
are using. Always use abrasive consumables
approved for use with your electrical power
tool. Abrasive consumables not approved for
use with your electrical power tool cannot be
adequately guarded and are unsafe.
b) To ensure the highest level of opera-
tional safety, the disc guard cover must
be attached to the electrical power tool
and set in such a way that the smallest
possible area of the abrasive consum-
able is exposed to the operator. The disc
guard cover is there to protect the operator from
pieces breaking off and accidental contact with
the abrasive consumable.
c) Abrasive consumables must be used
only for their recommended purpos-
es, For example: never grind with the
side face of a cutting disc. Cutting discs
are intended for removing material using the
edge of the disc. Sideways forces on these
abrasive consumables can cause them to break.
d) Always use an undamaged mounting
flange of the correct size and shape
for your selected grinding disc. Suitable
flanges support the grinding disc and reduce the
chance of it breaking. Flanges for cutting discs
are
different from the flanges for other abrasive discs.
e) Never use worn down abrasive con-
sumables intended for larger electrical
power tools. Abrasive consumables intended
for larger electrical power tools are not designed
for the faster rotational speeds of these smaller
electrical power tools and could break.
