Your saw comes standard with a chain
scabbard that matches the cutting
attachment.

If you use guide bars of different lengths
on the saw, the length of the chain
scabbard must be matched to the guide
bar to reduce the risk of injury. It should
cover the full length of the guide bar.
The length of the matching guide bars is
marked on the side of the chain
scabbard.

One chain scabbard extension is
required for guide bars longer than
35.4 in (90 cm). Two extensions are
required for guide bars longer than
47.2 in (120 cm).
Depending on original equipment, the
chain scabbard extension either comes
with the machine or is available as a
special accessory.
