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 Rollomatic guide bar
must match.
–
The drive link gauge (2) of the saw
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
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 correct 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 scabbard extension. Guide bars
longer than 120 cm require two
scabbard extensions.
Depending on the model, the scabbard
extension either comes standard with
the saw or is available as a special
accessory.
Fitting Chain Scabbard Extension
N
Push the scabbard extension and
chain scabbard together – the
lugs (1) must engage in the chain
scabbard.
