11.7 Replacing the chain
sprocket
Remove the chain and the guide bar as de-
scribed above. Using a screwdriver, strip
the snap safety ring [8-1] from the spindle
[8-4], and remove the washer [8-2] and
chain sprocket [8-3]. After replacement,
put the washer and safety ring back on.
11.8 Lubrication and cleaning
We recommend cleaning the machine reg-
ularly. Remove dust, cuttings, resin and
other impurities. Detergents that contain
solvents can harm the painted surfaces or
plastic parts. If you use such detergents,
we recommend that you fi rst test their
effect on a small hidden surface. During
maintenance or replacement of any part of
the tool cutting set, clean the inside of the
cover by removing the accumulated dust
and cuttings, clean the guide groove, as
well as the lubrication and tension ports
of the chain's guide bar. Do not clean the
rotary suction adaptor with your fi ngers!
The motor cover's ventilation ports must
not be blocked!
11.9 Replacing the carbon
brushes
WARNING
The saw must undergo safety inspection
to maintain its protection category, and
this work must be done at an authorised
facility licensed to perform such work. Be-
fore servicing the tool, always unplug the
cord from the socket!
Have an authorised service facility handle re-
placement of the brushes, power cord, etc. If
the machine is dropped, it must be checked
by an authorised service centre to prevent
any electrical or mechanical hazard.
After approximately 200 operating hours,
the brushes must be checked. The brushes
are accessible after removal of the hood.
The brushes must be replaced with new
ones if they become shorter than 5 mm.
The machine is equipped with self-detach-
ing brushes that come off automatically
once the minimum length is reached. Use
only original-equipment brushes!
12 Environmental
Protection / Disposal
Power tools, accessories and packaging
should be sorted for environmental-friendly
recycling.
Only for EC countries:
Do not dispose of power tools into
household waste!
According to the European Directive
2002/96/EC on waste electrical and elec-
tronic equipment and its incorporation into
national law, power tools that are no longer
suitable for use must be separately collect-

tal-friendly manner.
