e) Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage
of parts and any other condition that may
affect the power tool's operation. If dam-
aged, have the power tool repaired before
use. Many accidents are caused by poorly main-
tained power tools.
f) Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool
bits etc., in accordance with these instruc-
tions and in the manner intended for the
particular type of power tool, taking into
account the working conditions and the
work to be performed. Use of the power tool
for operations different from those intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Machine-specific
Safety Notes
B Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
B Take safety measures when dusts can be pro-
duced during working that are detrimental to
one's health, inflammable or explosive. Exam-
ple: Some dusts are regarded as carcinogenic. Use
suitable dust/chip extraction and wear a dust respi-
rator.
B Keep your workplace clean. Blends of materials
are particularly dangerous. Dust from light alloys
can burn or explode.
B Do not work materials containing asbestos.
Asbestos is considered carcinogenic.
B Never use the machine with a damaged cable.
Do not touch the damaged cable and pull the
mains plug when the cable is damaged while
working. Damaged cables increase the risk of an
electric shock.
B Connect machines that are used in the open
via a residual current device (RCD).
B Use the machine only for dry sanding. Penetra-
tion of water into the machine increases the risk of
an electric shock.

B Caution, fire hazard! Avoid overheating the
object being sanded as well as the sander.
Always empty the dust collector before taking
breaks. In unfavourable conditions, e. g., when
sparks emit from sanding metals, sanding debris in
the dust bag, micro filter or paper sack (or in the fil-
ter sack or filter of the vacuum cleaner) can self-
ignite. Particularly when mixed with remainders of
varnish, polyurethane or other chemical materials
and when the sanding debris is hot after long peri-
ods of working.
