Some terms that describe the bar and chain
When the cutting equipment supplied with your saw becomes
worn or damaged you will need to replace it. Use only the type
of bar and chain recommended by us. See the ”Technical data”
section to find out which equipment is recommended for your
saw.
kickback
!
Faulty cutting equipment or the wrong
combination of bar and chain increases the
risk of kickback. Use only the bar and chain
combinations recommended in the ”Technical
data” section.
Bar
The only way to avoid kickback is to make sure that the kick-
back zone of the bar never touches anything.
By using cutting equipment with “built-in” kickback protection
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.
