m) Clean the ventilation slots of your power tool regularly. The motor fan sucks
dust into the housing and a strong build-up of metal dust can cause electrical
hazards.
n) Do not use the power tool near flammable materials. Sparks may ignite such
materials.
o) Do not use accessory tools that require liquid coolant. Use of water or other
liquid coolants may cause electric shock.
Kickback and related safety regulations
Kickback is a sudden reaction caused when a rotating auxiliary tool, e.g. grinding
wheel, grinding belt, wire brush, etc. grabs or jams and leads to an abrupt stop of the
rotating auxiliary tool. If this happens, an uncontrolled power tool will quickly rotate
against the direction of rotation of the auxiliary tool.
If, for example, a grinding wheel gets stuck or jams, the edge of the grinding wheel
that is inserted into the workpiece may become jammed and break off from the
grinding wheel or cause a kickback. The grinding wheel can then fly towards or away
from the operator, depending on the direction of rotation of the wheel when it is
blocked. This can also cause grinding discs to break. Kickback is caused by incorrect
or improper use of the power tool. This can be avoided by taking the appropriate
precautions as described below.
General safety instructions for grinding, sanding with sandpaper, working with wire
brushes, polishing, milling and abrasive cutting:
a) This power tool is intended for use as a grinder, sander, steel brush, polisher,
milling machine and sanding machine. Observe all safety instructions,
diagrams and data supplied with the machine. Failure to observe the following
instructions may result in electric shock, fire and/or serious injury.
b) Do not use any accessories not supplied or recommended by the
manufacturer for this power tool. The fact that the accessories may be
attached to the power tool does not make them safe for use.
c) The permitted speed of the accessory used must be at least as high as the
maximum speed specified for the power tool. Accessories rotating faster than
the permitted speed may break and throw pieces into the air.
d) The external diameter and thickness of the auxiliary tool used must
correspond to the dimensions of your power tool. Incorrectly dimensioned
auxiliary tools cannot be adequately shielded or controlled.
e) Grinding discs, sanding drums or other accessories must fit precisely on the
grinding spindle or collet of your power tool. Accessories that do not fit
precisely into the mounting of the power tool will rotate unevenly, vibrate
heavily and may lead to loss of control.
