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

.
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.
