20.1 Inspecting and Maintaining the Hedge Trimmer

WARNING
To reduce the risk of personal injury from unintended
activation, remove the activation key before inspecting the
hedge trimmer or carrying out any maintenance, @ 8. Carry
out only the maintenance operations described in this
manual. There are no user-authorized repairs. STIHL
recommends that repair work be performed by authorized
STIHL servicing dealers.
To properly maintain the hedge trimmer:
► Have worn cutting blades replaced by an authorized
STIHL servicing dealer.
► Have missing or damaged safety labels replaced by an
authorized STIHL servicing dealer.
If you make a warranty claim for a component that has not
been serviced or maintained properly, coverage may be
denied.

20.2 Inspecting and Maintaining the Cutting Blades

WARNING
To reduce the risk of personal injury from unintended
activation, remove the activation key before inspecting the
cutting blades or carrying out any maintenance, @ 8.
STIHL recommends having the cutting blades sharpened by
an authorized STIHL servicing dealer.
Although it is best to have the cutting blades resharpened 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.
26
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. The file only sharpens 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, @ 22.2.
► Turn the hedge trimmer over and sharpen the cutting
edges of the lower cutting blade.
► 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 that 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.
