essential to comply with the
angles and dimensions specified
below. If the blade is incorrectly
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
• Only use cutting attachments with
t h e g u a r d s w e r e c o m m e n d ! S e e
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. 14-17)
• 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 file 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 flat
file.
• Sharpen all edges equally to maintain the
balance of the blade. (Fig. 14-17)
WARNING: Always discard a blade
that is bent, twisted, cracked,
broken or damaged in any other
way. Never attempt to straighten
a twisted blade so that it can be
reused. Only use original blades
of the specified type.
Trimmer head
CAUTION: Always ensure the
trimmer cord is wound tightly and
evenly around the drum, otherwise
the machine will generate harmful
vibration.
• Only use the recommended trimmer heads
and trimmer cords. These have been tested
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).
