Cutting Attachment

STIHL is the only manufacturer in the
industry to produce its own chain saws,
guide bars, saw chains and chain
sprockets.
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.
