g) If devices are provided for the connec-
tion of dust extraction and collection fa-
cilities, ensure these are connected and
properly used. Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was de-
signed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch
is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these in-
structions to operate the power tool.
Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for mis-
alignment or binding of moving parts,
breakage of parts and any other condi-
tion that may affect the power tool's op-
eration. If damaged, have the power tool
repaired before use. Many accidents are
caused by poorly maintained 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 in-
structions, taking into account the work-
ing conditions and the work to be per-
formed. 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 qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.
Safety Warnings for Sander
Use the machine only for dry sanding. Pen-
etration of water into the machine increases
the risk of an electric shock.
Pay attention that no persons are put at risk
through sparking. Remove any combustible
materials in the vicinity. Sparking occurs
when sanding metal materials.
Caution, fire hazard! Avoid overheating the
object being sanded as well as the sander.
Always empty the dust collector before tak-
ing breaks. In unfavourable conditions, e. g.,
when sparks emit from sanding metals, sand-
ing debris in the dust bag, micro filter or pa-
per sack (or in the filter sack or filter of the
vacuum cleaner) can self-ignite. Particularly
when mixed with remainders of varnish, poly-
urethane or other chemical materials and
when the sanding debris is hot after long
periods of working.
When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
