English
► Periodically clean the oil inlet hole (1), oil outlet
channel (2) and bar groove (3).

along the guide bar with a flat file or a STIHL guide bar
dressing tool.
► Replace the guide bar if the burrs cannot be filed or if the
guide bar becomes damaged.
20.5 Inspecting, Maintaining and Sharpening the
Saw Chain
WARNING
An improperly sharpened saw chain can increase the risk of
kickback and other reactive forces, resulting in severe
personal injury or death. For example, depth gauges that are
too low or cutters that are filed incorrectly can increase the
kickback tendency of the chain saw and can increase
kickback forces, making it more difficult to control the saw.
Always review and follow the sharpening angles and
dimensions recommended by STIHL when checking or
sharpening the saw chain.
WARNING
Never use a dull or damaged saw chain. This leads to
increased physical strain, increased vibration load,
unsatisfactory cutting results and increased wear. If the
chips from cutting are fine, more like saw dust than wood
chips, the chain likely is dull.
► Switch off the chain saw, engage the chain brake and
disconnect the chain saw from the power supply.

► Check the height of the depth gauge (1) with a STIHL file
► If the depth gauge protrudes higher than the file gauge,
► Work carefully. Do not file the depth gauge too low. A
STIHL saw chain is manufactured with wear marks to help
the operator identify excessive wear. The wear marks
depicted above (1 - 4) must remain visible.
► Replace the saw chain if any wear marks are no longer
► Check the sharpening angle of the cutters with a STIHL
► If the sharpening angle is incorrect, file the cutters to the
