maximum speed specified for the power tool. Accessories that rotate faster than
the permissible rate can break and throw pieces into the air.
e) The external diameter and thickness of the accessory tool used must comply with
the dimensions of your power tool. Incorrectly dimensioned accessory tools
cannot be sufficiently shielded or controlled.
f) Grinding discs, sanding drums or other accessories must match the grinding
spindle or collet chuck of your power tool exactly. Accessory tools which do not fit
precisely into the take-up of the power tool will rotate unevenly, vibrate severely
and can lead to a loss of control.
g) Hold the power tool only by the insulated gripping surfaces when performing an
operation where the accessory tool may contact hidden wiring or its own cord.
Contact with a live cable can also make metal parts of the appliance live and
could result in an electric shock.
h) Always hold the power tool firmly. When running up to full speed, the torque of
the motor can cause the power tool to twist.
i) If possible, use clamps to hold the workpiece in position. Never hold a small
workpiece in one hand and the power tool in the other while you are using it. By
clamping small workpieces, you keep both hands free for better control of the
power tool. When cutting round workpieces such as dowels, rods or pipes, be
aware that these can roll away and this can cause the tool to jam and be thrown
towards you.
j) Never put the power tool down until the accessory tool 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.
k) When changing accessory tools or changing settings, tighten the collet nut, the
chuck or other fixing elements tightly. Loose fastening elements can shift
unexpectedly and lead to loss of control; unsecured, rotating components will fly
off violently.
l) Do not leave the power tool running whilst carrying it. Accidental contact between
you clothing and the rotating accessory tool could lead to physical injury.
m) 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.
n) Do not use the power tool in the vicinity of flammable materials. Sparks can ignite
such materials.
o) Do not use any accessory tools which require liquid coolant. The use of water or
other liquid coolants may lead to electric shock.
SAFETY INSTRUCTIONS FOR ALL APPLICATIONS
Kickback and corresponding safety instructions
Kickback is a sudden reaction caused when a rotating accessory tool, e.g. grinding
disc, grinding band, wire brush, etc., catches or jams and leads to an abrupt stop of
the rotating accessory tool. If this happens, an uncontrolled power tool will turn
rapidly against the direction of rotation of the accessory tool.
If, for example, a grinding disc catches or jams, the edge of the grinding disc that is
projecting into the workpiece can get caught and break off the grinding disc or cause
a kickback. The grinding disc can then fly in the direction of the operator or away
from him, depending on the direction of rotation of the disc at the blockage. This can
also break grinding discs. A kickback is caused by improper or incorrect use of the
power tool. This can be avoided by taking proper precautions as described below.
General safety instructions for grinding, sandpaper sanding, working with wire
brushes, polishing, milling and abrasive cutting:
a) This power tool is intended for use as a grinder, sandpaper sander, wire brush,
polisher, milling machine and abrasive cutting machine.
