You can run chains of different pitches
on this chainsaw – depending on the
chain sprocket (see "Specifications"):
The chain pitch (1) must match the pitch
of the sprocket and the guide bar (for
Rollomatic). The drive link gauge (2)
must match the bar groove width (3).
The pitch is marked on the chain
sprocket and guide bar in inches
(e.g. 3/8 or .325). The groove width
is marked on the guide bar in
millimeters (e.g. 1.6).
If non-matching components of the
wrong pitch or drive link gauge are
run together on the same machine
they may be damaged beyond
repair after a short period of
operation.
