To do a check of the muffler
WARNING:
Never use a product with a
faulty muffler.
WARNING:
Bear in mind that the
exhaust fumes from the engine are hot and
may contain sparks which can start a fire.
Never start the product indoors or near
combustible material!
The muffler keeps noise levels to a minimum and sends
exhaust fumes away from the operator. For mufflers it is
very important that you follow the instructions on how to
check, maintain and service your product.
• Regularly check that the muffler is securely attached
to the product.
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 can not 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.
Personal protective equipment
