22.2 Inspecting and Maintaining the Cutting Blades

WARNING
To reduce the risk of personal injury from unintended
activation, remove the battery before inspecting the cutting
blades or carrying out any maintenance, @ 8.1. To help
prevent injuries, always wear heavy-duty work gloves when
handling the hedge trimmer or its cutting blades, @ 6.3.
STIHL recommends having the cutting blades sharpened by
an authorized STIHL servicing dealer.
Although it is best to have the cutting blades sharpened by
a dealer on a workshop sharpener, it is possible to use a flat
crosscut sharpening file.
Sharpen the cutting blades when cutting performance
begins to deteriorate, i.e., blades frequently snag on
branches or fail to cut material cleanly.
To sharpen the cutting blades with a file:
► Sharpen each cutting edge of the upper cutting blade with
a sharpening file. Always file toward the cutting edge with
a forward motion matching the sharpening angle, @ 24.3.
Sharpen on the forward stroke. Lift off the blade on the
backstroke.
