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 you use guide bars of different lengths
on the saw, the length of the chain
scabbard must be matched to the guide
bar to 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.
Removing the chain sprocket cover
N Unscrew the nut and remove the
chain sprocket cover.
N Turn the screw (1)
counterclockwise until the tensioner
slide (2) butts against the left end of
the housing slot.
