Mounting The Bar And Chain (Side Chain Tensioner) - Stihl MS 251 Manual De Instrucciones

English
Chain scabbard
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 help 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.
