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, @ 9.1. 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.
32
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, @ 24.2.
Sharpen on the forward stroke. Lift off the blade on the
backstroke.
► Only sharpen the cutting edges. Do not file blunt
projecting parts of the cutting attachment, or the cutting
blade guard. Make sure your sharpening stroke matches
the sharpening angle, @ 24.2.
► Turn the hedge trimmer over.
► Use a whetstone to remove any burrs from the cutting
edges. Remove as little material as possible.
► After sharpening, wipe away filing or grinding dust with a
dry or slightly dampened cloth and then spray the cutting
blades with a resin solvent, such as STIHL Resin
Remover and Lubricant.
If you make a warranty claim for a component which has not
been serviced or maintained properly, coverage may be
denied.
NOTICE
Operating the machine with dull or damaged cutting blades
may overload the motor. Keeping the cutting blades sharp
helps maintain cutting performance and the expected life of
the product.
