Overview
Packaged as a matched set, this 12” guide bar and chain combo delivers factory-level cutting performance as an aftermarket replacement. When either the bar or chain shows significant wear, the best practice is to replace both simultaneously. This combo simplifies the process and guarantees proper fitment between the two components.

Installation notes
Disconnect power or remove the spark plug wire before working on the cutting assembly.

Common questions
Q: Will this 12-inch guide bar 3670 005 0064 fit my chainsaw, or is it only compatible with certain models?
This guide bar is only compatible with specific chainsaw models, so you’ll want to match the bar number 3670 005 0064 and confirm fitment against the listing before installing it. The safest check is to compare your current bar’s mount pattern, bar length, chain pitch, and gauge to your original setup.
Q: Can I reuse my old chain with this 12-inch replacement guide bar, or do I need a matching new chain?
You can only reuse the old chain if it matches the new bar’s exact specifications for length, pitch, and gauge and is still in good condition. If the old chain is stretched, worn, or doesn’t sit properly in the bar groove, replace it with the correct matching chain to avoid poor cutting performance and premature bar wear.
Q: What should I do during installation and maintenance to keep this chainsaw blade and guide bar working properly?
When installing the bar, make sure the chain tension is snug but still allows the chain to move freely by hand, and verify the chain is facing the correct cutting direction. For maintenance, keep the bar groove clean, check that the oiling hole is not blocked, and periodically inspect the rails for uneven wear so the bar and chain last longer.
