angles and dimensions specifi ed

sharpened there is a risk of
increased kickout of the brush
cutter and increase risk of thrown
object, with resulting risk of injury.
Failure to replace or repair
damaged cutting attachment can
cause serious injury.
The blades are very sharp, always
wear protective gloves when
performing maintenance to the
blades.
General rules

Recommended cutting attachments
(Page 10).
• Keep the teeth of the blade correctly
sharpened! Follow our instructions and
use the recommended file gauge. An
incorrectly sharpened or damaged blade
increases the risk of accidents. (Fig. 11-17)
• Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.
• Resharpen frequently, take away as little
material as possible – two or three strokes
of the fi le are usually enough.
To avoid out-of-balance:
• Resharpen the cutters uniformly – do not
alter the contour of the parent blade in any
way.
• After resharpening about 5 times, have
blade checked by your dealer.

MAINTENANCE
WARNING: Never repair damaged
cutting attachments by welding,
straightening or modifying the
shape. This may cause parts of the
cutting tool to come off and result
in serious or fatal injuries.
Sharpening grass cutters and grass blades
• See the cutting attachment packaging for
correct sharpening instructions. Sharpen
blades and cutters using a single-cut fl at

balance of the blade. (Fig. 11-17)
WARNING: Always discard a blade
that is bent, twisted, cracked,

trimmer cord is wound tightly and
evenly around the drum, otherwise

by the manufacturer to suit a particular
engine size. This is especially important
when a fully automatic trimmer head is
used. Only use the recommended cutting
attachment. See Recommended cutting
attachments (Page 10).
