Baumr-AG SX25 Chain Questions

What size chain does a Baumr-AG SX25 take?

How many drive links is a Baumr-AG SX25 chain?

40 DL on the 10" bar. The DL count is usually stamped on the bar itself, or count the drive links on your old chain.

What file do I use on an SX25 chain?

A 4.0mm round file suits this 3/8" LP chain.

Will this chain fit other Baumr-AG saws?

Possibly, but please use our Search by Chainsaw tool to find your specific saw chain with no doubt.

Is this a genuine Baumr-AG chain?

No — it's an Alpine Chain Co. chain manufactured to fit the Baumr-AG SX25, replacing the factory 10" 40-link chain and matching the Oregon 91PX. The SX25 ships with a full-chisel chain; ours is semi-chisel, chosen for Australian hardwood, and fits the same bar. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Baumr-AG SX25, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
