• To loosen and tighten the locknut, use a socket
wrench with a long shaft. The arrow in the picture
shows the area where you can operate the socket
wrench.
WARNING: When you loosen and
tighten the locknut, there is a risk of
injury from the blade. You must always
make sure that the blade guard prevents
injury to your hand when you do this.
Note: Make sure that you cannot turn the locknut by
hand. Replace the nut if the nylon lining does not have a
resistance of a minimum of 1.5 Nm. The locknut must be
replaced after it has been put on approximately 10
times.
Cutting equipment
Select correct cutting equipment and do maintenance on
the cutting equipment to:
• Get maximum cutting performance.
• Increase lifetime of the cutting equipment.
WARNING: Only use cutting attachments
with the guards we recommend! See
Accessories on page 22 . Refer to the
instructions for the cutting attachment to find
the correct way to load the trimmer line and
the correct trimmer line diameter.
WARNING: A defective cutting attachment
may increase the risk of accidents.
WARNING: Always stop the engine before
you do the work on the cutting attachment.
This continues to rotate after you release the
throttle. Make sure that the cutting
attachment has stopped fully and disconnect
the spark plug cap before you start the work
on it.

Trimmer head
WARNING: Always make sure the trimmer
line is wound tightly and evenly around the
drum to prevent harmful vibration.
• Only use recommended trimmer heads and trimmer
lines.
• Only use recommended cutting attachments.
• Smaller machines requires small trimmer heads and
vice versa.
• The length of the trimmer line is 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 cuts the trimmer line to the correct
length.
• Soak the trimmer line in water for a couple of days
before use to increase the life length.
