GENERAL SAFETY PRECAUTIONS
WARNING:
Always stop the en-
gine before doing any work on the
cutting attachment. This continues
to rotate even after the throttle has
been released. Ensure that the
cutting attachment has stopped
completely and disconnect the
lead from the spark plug before
you start to work on it.
WARNING:
Using an incorrect
cutting attachment or an incorrect-
ly sharpened blade increases the
risk of kickback.
Cutting equipment
Grass blades and grass cutters are in-
tended for cutting coarse grass.
A trimmer head is intended for trimming
grass.
General rules
Only use cutting attachments with the
guards we recommend! See the section on
Technical data.
Keep the teeth of the blade correctly sharp-
ened! Follow our instructions and use the
recommended file gauge. An incorrectly
sharpened or damaged blade increases the
risk of accidents.
Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.

Sharpening grass cutters and
grass blades
S See the cutting attachment packaging for
correct sharpening instructions. Sharpen
blades and cutters using a single- -cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.
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 re-
used. Only use original blades of
the specified type.
Trimmer head
IMPORTANT!
Always ensure the trimmer line is wound
tightly and evenly around the drum, other-
wise the machine will generate harmful
vibration.
S Only use the recommended cutting at-
tachments. See the section on "Technical
data".
S Smaller machines generally require small
trimmer heads and vice versa. This is be-
cause when clearing using trimmer line
the engine must throw out the trimmer
line radially from the trimmer head and
overcome the resistance of the grass
being cleared.
S The length of the trimmer line is also im-
portant. A longer trimmer line requires
greater engine power than a shorter
trimmer line of the same diameter.
S Make sure that the cutter on the trimmer
guard is intact. This is used to cut the
trimmer line to the correct length.
S To increase the life of the trimmer line it
can be soaked in water for a couple of
days. This will make the line tougher so
that it lasts longer.
