protects you against small grinding chips
and material particles. Protect your eyes
against foreign objects which fly off during
different operations. The purpose of dust masks
and breathing equipment is to filter the dust
generated during the operation. Long-term
exposure to high noise pollution may cause
hearing loss.
i) Make sure that other persons stay a safe
distance away from your working area.
Persons accessing your working area must wear
personal protective equipment. Fragments of
the work piece or broken insertion tools may
fly off and cause injury even outside the direct
working area.
j) Always hold the tool by its insulated
handles when the insertion tool may come
into contact with hidden power lines or with
the power cord of the power tool. Contact
with live lines may energise metal tool parts and
cause electric shock.
k) Keep the power cord away from rotating
insertion tools. If you lose control of the power
tool, the power cord may be cut or trapped, and
your hand or arm may get into the path of the
rotating insertion tool.
l) Never put aside the power tool before the
complete halt of the insertion tool. Rotating
insertion tools may get in contact with the place
of deposit thus causing the loss of control of the
tool.
m) Switch off the power tool while you carry
it around. Your clothes may be trapped when
unintentionally getting in contact with the
rotating insertion tool and the insertion tool
may penetrate your body.
n) The ventilation slots of your power tool
must be cleaned on a regular basis. The motor
fan sucks in dust, and the accumulation of metal
dust may cause electrical risks.
o) Do not use the power tool in the vicinity
of inflammable materials. Sparks may ignite
these materials.
p) Do not use insertion tools which require
liquid coolants. Using water or other liquid
coolants may cause electric shock.
4.7 Further safety notes for all applications –
kickback and corresponding safety notes
A kickback is the sudden reaction caused by
rotating insertion tools such as a grinding disk,
grinding plate, wire brush, etc. which has got
caught or which blocks. Getting caught or
blocking results in the immediate stop of the
rotating insertion tool. This accelerates the
uncontrolled power tool against the rotary
direction of the insertion tool.
If for example a grinding disk gets caught
or blocks in the work piece, the edge of the
grinding disk which penetrates the work piece
may get caught, the grinding disk will make
a sudden movement or cause a kickback. As
a result, the grinding disk moves towards the
operator or away from the operator, depending
on the rotary direction of the disk when it
blocks. This may also cause the fracture of
grinding disks.
Kickbacks are the result of the improper or
incorrect use of power tools. Kickbacks can
be avoided when observing the following
precautionary measures.
a) Hold the power tool firmly in your hands
and bring your body and arms in a position
which allows you to adequately react to
kickback forces. Always use the additional
handle, if available. This ensures you the
utmost control of kickback forces or reaction
torques when starting your power tool. When
taking appropriate precautions, the operator is
in the position to control kickback and reaction
forces.
