Special Accessories
Chain scabbard
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 help reduce the risk of injury.
If the chain scabbard does not cover the
full length of the guide bar, a suitable
chain scabbard or a scabbard extension
is necessary.
Depending on the model, the scabbard
extension either comes standard with
the saw or is available as a special
accessory.
