Stihl MSA 160 C Instruction Manual page 85

To check the angles
STIHL filing gauge (special accessory,
see table "Sharpening tools") – a
universal tool for checking sharpening
and side plate angles, depth gauge
setting, and tooth length, as well as
cleaning grooves and oil inlet holes.
Proper sharpening
Remove the battery from the
N
machine
Select sharpening tools in
N
accordance with chain pitch
Clamp guide bar if necessary
N
To advance the saw chain, set the
N
chain saw hand guard to ‚ – chain
brake is released
Sharpen frequently, removing little
N
material – two or three strokes of the
file are usually sufficient for simple
resharpening
MSA 160 C, MSA 200 C
Guide the file: horizontally (at a right
N
angle to the side surface of the
guide bar) in accordance with the
specified angle – according to the
markings on the file holder – rest the
file holder on the tooth head and the
depth gauge
File only from the inside outward
N
The file only sharpens on the
N
forward stroke – lift the file on the
backstroke
Do not file tie straps and drive links
N
Rotate the file a little periodically in
N
order to avoid uneven wear
To remove file burr, use a piece of
N
hardwood
Check angle with file gauge
N
All cutters must be equally long.
With varying cutter lengths, the cutter
heights also vary and cause rough
running of the saw chain and chain
breakage.
All cutters must be filed down equal
N
90° to the length of the shortest cutter –
ideally, one should have this done in
the workshop using an electric
sharpener
Depth gauge setting
The depth gauge determines the depth
to which the cutter penetrates the wood
and thus the chip thickness.
a Required distance between depth
gauge and cutting edge
When cutting softwood outside of the
frost season, the distance can be
increased by up to 0.2 mm (0.008").
