The file only sharpens on the forward stroke. ► Do not file tie straps or drive links. ► Periodically rotate the file in order to avoid uneven wear. ► 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 kickback and other 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 kickback and other 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 will increase the kickback tendency of the chain saw and can increase kickback 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, @ 24.5. 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. 0458-890-8621-B 57

22 Inspection and Maintenance
Guide the file horizontally at a right angle to the side
surface of the guide bar in accordance with the specified
angle.
File only from the inside of the cutter outward.
Lift the file on the backstroke. The file only sharpens on
the forward stroke.
Do not file tie straps or drive links.
Periodically rotate the file in order to avoid uneven wear.
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 kickback and other 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 kickback and other 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 will increase the kickback
tendency of the chain saw and can increase kickback 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,
@
24.5.
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.
