Important Fitment Information

Before ordering, confirm your chainsaw's bar mount, chain pitch, gauge and drive-link count.

This combo uses a .325" pitch chain and requires a matching .325" drive sprocket. It is not a direct replacement for a chainsaw configured with a 3/8" drive sprocket.

The included chain has .063" gauge and 81 drive links. It is not interchangeable with .050" or .058" gauge chains unless the guide bar is also matched to the correct gauge.

Do not select a replacement solely by chainsaw model or 20" bar length. Compare your original guide bar specifications and verify your equipment's drive system.

Follow the chainsaw manufacturer's instructions for installation, chain tension, lubrication and safe operation.
