22 Inspection and Maintenance
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.
Grass Blades
To sharpen the grass blades with a file:
► Remove the grass blades from the garden shears,
@ 13.2.
► Move the upper grass cutting blade fully in one direction
so that one side of the cutting edges is easily accessible.
► Sharpen each accessible cutting edge of the upper grass
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.
► Move the upper grass cutting blade fully in the other
direction so that the other side of the cutting edges is
easily accessible and sharpen the rest of the cutting
edges.
► Use a whetstone to remove any burrs from the cutting
edges. Remove as little material as possible.
