Scheppach DS920 Operating Manual page 25

g) Never use damaged accessory tools. Before
each use inspect the accessory such as abra-
sive wheels for chips and cracks, backing pad
for cracks, tear or excess wear, wire brush for
loose or cracked wires. If the power tool or the
accessory tool in use is dropped, check to see
if it is damaged or use an undamaged acces-
sory tool. When you have checked and insert-
ed the accessory tool, ensure that you and any
other people in the vicinity remain outside of
the level of the rotating accessory tool and
allow the tool to rotate at maximum speed for
one minute. Damaged tool attachments usually
break during this test period.
h) Wear personal protective equipment. De-
pending on application, use face shield,
safety goggles or safety glasses. Where ap-
propriate, wear a dust mask, hearing pro-
tection, protective gloves or a special apron
that will keep small grinding and material
particles away from you. The eye protection
must be capable of stopping flying debris gen-
erated by various operations. Dust or breathing
masks must filter the dust generated during use.
Prolonged exposure to high intensity noise may
cause hearing loss.
i) Ensure that other people remain at a safe dis-
tance from your workspace. Anyone who en-
ters the workspace must wear personal pro-
tective equipment. Fragments of workpiece or of
a broken accessory may fly away and cause injury
beyond immediate area of operation.
j) Hold power tool by insulated gripping surfac-
es only, when performing an operation where
the cutting accessory may contact hidden wir-
ing or its own cord. Contact with a live wire may
make exposed metal parts of the power tool live
and could give the operator an electric shock.
k) Keep the power cord away from any rotating
accessories. If you lose control, the cord may
be cut or snagged and your hand or arm may be
pulled into the spinning accessory.
l) Never put the power tool down until the acces-
sory tool being used has come to a complete
standstill. The rotating accessory tool can come
into contact with the surface and cause you to
lose control of the power tool.
m) Do not run the power tool while carrying it
at your side. Accidental contact of your cloth-
ing with the rotating attachment part could lead
to an injury.
n) Clean the ventilation slits of your power tool
regularly. The engine fan draws dust into the
housing and a strong accumulation of metal dust
can cause electrical hazards.
o) Never use the power tool in the vicinity of in-
flammable materials. Sparks can ignite such
materials.
p) Do not use any accessory tools which require
liquid coolant. The use of water or other liquid
coolants may lead to an electric shock.
Safety instructions for all applications − kick-back
and corresponding safety instructions
Kick-back is the sudden reaction resulting from a caught
or jammed rotating insert tool, such as a grinding disc,
grinding wheel, wire brush, etc. Catching or jamming
results in the rotating insert tool stopping abruptly.
As a result, an uncontrolled electric tool is accelerated
against the direction of rotation of the tool attachment
at the blocking point.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the sur-
face of the material causing the wheel to climb out or
kick out. The grinding disc may either jump toward or
away from the operator, depending on direction of the
wheel's movement at the point of pinching. Abrasive
wheels may also break under these conditions.
Kickback is the result of incorrect or deficient use of
the power tool.
It can be prevented by suitable precautionary meas-
ures, as described in the following.
a) Hold the power tool firmly in both hands and
position your body and arms so they can ab-
sorb the force of a kickback. Always use the
additional handle, if available, so that you
have the maximum possible control over the
kickback force or reaction forces at full speed.
By taking adequate precautions, the operator can
stay in control of the kickback and reaction forces.
b) Never hold your hand close to a rotating ac-
cessory tool. The accessory tool could jump out
of your hand if there is a kickback.
c) Avoid having any part of your body in the re-
gion in which the power tool is likely to move
in event of a kickback. The kickback will force the
power tool in the opposite direction to the direction
of rotation of the grinding disc at the blockage.
