Accessories

We recommend only to use the listed guide bar and saw
chain combinations.
Low kickback saw chain
A saw chain that is designated as Low kickback saw
chain, meets the low kickback requirement specified in
ANSI B175.1-2012.
Kickback and guide bar nose radius
For sprocket nose bars the nose radius is specified by
the number of teeth, such as 10T. For solid guide bars
the nose radius is specified by the dimension of the
nose radius. For a given guide bar length, you can use a
guide bar with smaller nose radius than given.
Note:
The usable cutting length is usually 1 in less
than the nominal guide bar length.
