General safety advice for electrical power tools
General safety advice for electrical power tools
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 mis-
use 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 kick-
back.
A kickback moves the electrical power
tool in the opposite direction to the direction 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 kick-
back.
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.
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 consuma-
bles approved for use with your elec-
trical 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 purposes,
For example: never grind with the side
face of a cutting disc.
Cutting discs are in-
tended 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.
Further special safety
advice for disc-cutting
a)
Avoid snagging the cutting disc and
do not use too much contact pressure.
Do not attempt to make excessively
deep cuts.
Overloading the cutting disc in-
