5 Cutting Attachment
A cutting attachment consists of the saw chain,
guide bar and chain sprocket.
The cutting attachment that comes standard is
designed to exactly match the chain saw.

– The pitch (t) of the saw chain (1), chain
sprocket and the nose sprocket of the Rollo‐
matic guide bar must match.

5.1 Chain Scabbard
Your saw comes standard with a chain scabbard
that matches the cutting attachment.
If guide bars of different lengths are mounted to
the saw, always use a chain scabbard of the cor‐
rect length which covers the complete guide bar.
The length of the matching guide bars is marked
on the side of the chain scabbard.
Guide bars longer than 90 cm require one scab‐
bard extension. Guide bars longer than 120 cm
require two scabbard extensions.
Depending on the model, the scabbard exten‐
sion either comes standard with the saw or is
available as a special accessory.
