► Use a file holder
Always use a file holder (special accessory, see
table "Sharpening tools") when sharpening saw
chains by hand. File holders have markings for
the sharpening angle.
Use only special saw chain files! Other files are
unsuitable in terms of shape and type of cutting.
30.5 To check the angles
001BA203 KN
STIHL filing gauge (special accessory, see table
"Sharpening tools") – a universal tool for check‐
ing sharpening and side plate angles, depth
gauge setting, and tooth length, as well as clean‐
ing grooves and oil inlet holes.
30.6 Proper sharpening
► Select sharpening tools in accordance with
chain pitch
► Clamp guide bar if necessary
► Block saw chain – push the hand guard for‐
ward
► To advance the saw chain, pull the hand
guard toward the handlebar: The chain brake
is disengaged. With the Quickstop Super
chain brake system, additionally press the
throttle trigger lockout
► Sharpen frequently, removing little material –
two or three strokes of the file are usually suffi‐
cient for simple resharpening

► Guide the file: horizontally (at a right angle to
the side surface of the guide bar) in accord‐
ance 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
► The file only sharpens on the forward stroke –
lift the file on the backstroke
► Do not file tie straps and drive links
► Rotate the file a little periodically in order to
avoid uneven wear
► To remove file burr, use a piece of hardwood
► Check angle with file gauge
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 to the
length of the shortest cutter – ideally, one
should have this done by a servicing dealer
using an electric sharpener
