3. Make sure that the vibration damping units are
attached correctly.
To do a check of the muffler
The muffler keeps noise levels to a minimum and sends
exhaust fumes away from the operator.
• Do a visual check for damage and deformation.
• Make sure that the muffler is correctly attached to
the product.
• If the muffler on your product has a spark arrester
screen, do a visual check. Replace the spark
arrester screen if it is damaged.
a) Clean the spark arrester screen if it is blocked. A
blocked spark arrester screen causes the engine
to become too hot which causes damage to the
engine.

b) Make sure that the spark arrestor mesh is
attached correctly.
To attach and remove the locknut
WARNING: Stop the engine, use protective
gloves and be careful around the sharp
edges of the cutting attachment.
A locknut is used to attach some types of cutting
attachments. The locknut has a left thread.
• To attach, tighten the locknut in the opposite
direction to the direction of turning of the cutting
attachment.
• To remove the locknut, loosen the locknut in the
same direction as the cutting attachment rotates.
• 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.
