General rules
Only use cutting attachments with the guards we
recommend. See the "TECHNICAL DATA"
section.
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.
Check the cutting attachment for damage or
cracks. A damaged cutting attachment should
always be replaced.
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.
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
IMPORTANT: Always ensure the trimmer line is
wound tightly and evenly around the drum;
otherwise the machine may generate vibration
which could be harmful.
GENERAL SAFETY PRECAUTIONS
Only use the recommended cutting
•
attachments. See the "TECHNICAL DATA"
section.
Smaller machines generally require small
•
trimmer heads and vice versa. This is because
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.
The length of the trimmer line is also
•
important. A longer trimmer line requires
greater engine power than a shorter trimmer
line of the same diameter.
Make sure that the cutter on the trimmer guard
•
is intact. This is used to cut the trimmer line to
the correct length.
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.
