22 Inspection and Maintenance

22.1 Garden Shears

WARNING
To reduce the risk of personal injury from unintended
activation, remove the battery before inspecting the garden
shears or carrying out any maintenance, @ 9. 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.
Proper maintenance of the garden shears includes the
following activities:
► Sharpen the cutting blades.
► Replace worn or damaged cutting blades.
► Have worn, 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.

22.2 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. To help
prevent injuries, always wear heavy-duty work gloves when
handling the garden shears or the cutting blades, @ 6.4.
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, it is possible to use a flat, crosscut sharpening file
to sharpen the cutting blades.
Sharpen the cutting blades when cutting performance
begins to deteriorate, i.e., blades frequently snag on
branches or fail to cut material cleanly.

Shrub Blades
To sharpen the shrub blades with a file:
► Remove the shrub blades from the garden shears,
@ 13.2.
► Sharpen each cutting edge of the upper shrub 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, @ 24.2.
► Turn the shrub blades over and sharpen the cutting edges
of the lower shrub 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.
