Stihl TSA 230 Notice D'emploi page 79

g) The outer diameter and thickness of
the tool being used must
correspond to the dimensions of
your electrical power tool.
Incorrectly measured tools that are
used cannot be adequately shielded
or controlled.
h) Abrasive wheels and flanges must
fit exactly onto the grinding spindle
of your electrical power tool. Tool
bits that do not fit exactly onto the
grinding spindle of the electrical
power tool, rotate unevenly, vibrate
a lot and can result in loss of control.
i) Do not use damaged abrasive
wheels. Before each use, check the
abrasive wheels for splitting and
cracks. If the electrical power tool or
abrasive wheel falls, check if it is
damaged or use an undamaged
abrasive wheel. Once you have
checked the abrasive wheel and
started it, make sure that you and
everyone else nearby remain
outside of the area of the rotating
abrasive wheel and allow the
machine to run for a minute at
maximum speed. Damaged
abrasive wheels usually break
during this test period.
j) Wear personal protective
equipment. Depending on the
operation, wear full face protection,
eye protection or safety glasses.
Where appropriate, wear a dust
mask, ear protection, protective
gloves or a special apron that keeps
small ground particles and material
particles away from you. Eyes must
be protected against foreign bodies
flying around that occur with certain
applications. The dust mask or
TSA 230
respirator must filter the dust
created during the operation. If
subjected to loud noise for a longer
period of time, you may suffer from
loss of hearing.
k) Make sure that other persons keep
a safe distance to your work area.
Anyone entering the work area must
wear personal protective
equipment. Fragments from the
workpiece or broken tool bits can fly
off and cause injuries even when
the person is outside of the direct
work area.
l) Hold the machine only by the
insulated handle surfaces when
carrying out work where the tool bit
can hit hidden power lines. Contact
with a live line can also render metal
machine parts live and cause an
electric shock.
n) Never put the electrical power tool
down before the tool bit has fully
stopped. The rotating tool bit could
make contact with the surface,
causing you to loose control of the
electrical power tool.
o) Do not leave the electrical power
tool running whilst carrying it. Your
clothing may get caught in the
rotating tool bit and the tool bit may
penetrate your body.
p) Clean the vents of your electrical
power tool regularly. The engine fan
attracts dust into the housing and
the large volume of metal dust
collected can be an electrical
hazard.
q) Do not use the electrical power tool
near combustible materials. Sparks
can ignite these materials.
8) Additional safety instructions for
abrasive wheel applications
Kickback and associated safety
instructions
Kickback is the sudden reaction as a
result of a catching or blocked rotating
abrasive wheel. Catching and blocking
causes the rotating tool bit to stop
abruptly. An uncontrolled electrical
power tool is thereby accelerated
against the direction of rotation of the
tool bit at the blockage site.
If for example an abrasive wheel
catches or blocks in the workpiece, the
edge of the abrasive wheel that
penetrates the workpiece can be
caught, thereby causing the abrasive
wheel to break away or a kickback. The
abrasive wheel then travels towards or
away from the operator depending on
the direction of rotation of the wheel at
the blockage site. Abrasive wheels can
also break in this instance.
A kickback is the result of the incorrect
or faulty use of the electrical power tool.
It can be prevented by taking suitable
measures, as described below.
a) Hold the electrical power tool firmly
and make sure your body and arms
are in a position so that you can
catch the kickback forces. Always
use the additional handle, if
available, to maintain the best
