Stihl GTA 26 Notice D'emploi page 38

English
► To remove a file burr from the cutter tooth, run the cutter
across a piece of hardwood.
► Check the sharpening angle with a file gauge.
All cutters must be of equal length and filed down to the
length of the shortest cutter. Otherwise, the tendency and
force of reactive forces will increase.
STIHL recommends having your chain sharpened by an
authorized STIHL servicing dealer to reduce the risk of
severe or fatal injury from an improperly sharpened chain.
WARNING
Depth gauges that are too low increase the potential and
force of reactive forces, which can increase the risk of
serious personal injury. Always maintain the proper
distance (a) between the depth gauge and the top of the
cutter.
The depth gauge determines the depth to which the cutter
penetrates the wood and thus the chip thickness.
A depth gauge that is too low can increase reactive forces.
A depth gauge that is too high will prevent the cutter from
entering the workpiece and will lead to poor cutting
performance. Always keep the required distance (a)
between depth gauge and cutting edge, @ 24.4.

To properly lower the depth gauge:
► Lay the appropriate file gauge for the chain pitch on the
chain and press it against the cutter to be checked. If the
depth gauge protrudes past the file gauge, the depth
gauge must be filed down.
► File the depth gauge so that it is flush with the top of the
file gauge.
a
► Afterwards, remove the file gauge and file the leading
edge of the depth gauge parallel to the service mark.
When doing this, be careful not to further lower the highest
point of the depth gauge.
► Lay the file gauge on the chain to check the height of the
file gauge. The highest point of the depth gauge must be
flush with the top of the file gauge.
► After sharpening, clean the chain thoroughly, removing
any filings or grinding dust.
► Oil the chain thoroughly.
