A burr can build up on the outer edge of the guide bar.
► Remove burr with a flat file or a STIHL guide bar dressing
tool.
► If you have any queries: Contact your STIHL servicing

16.2 Sharpening the Saw Chain

Correctly sharpening saw chains requires a lot of practice.
STIHL files, STIHL filing aids, STIHL sharpeners and the
brochure "Sharpening STIHL Saw Chains" help you achieve
the right results. To obtain the brochure visit

STIHL recommends you have saw chains resharpened by a
STIHL servicing dealer.

► File each cutter with a round file so that the following
points are observed:
– Round file matches the chain pitch.
– File from the inside to the outside of the cutter.
– Hold the file at right angle to the guide bar.
– Maintain a filing angle of 30°.
► File down the depth gauges with a flat file so that they are
level with the STIHL filing gauge and parallel to the service
mark. The STIHL filing gauge must match the chain pitch.
► If you have any queries: Contact your STIHL servicing
dealer for assistance.
