MS 441

English

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

Push the scabbard extension and

chain scabbard together – the

lugs (1) must engage in the chain

scabbard.
