EGO PSA1000 Chain Questions

What size chain does an EGO PSA1000 take?

3/8" LP pitch, 0.043" (1.1mm) gauge on the PSA1000. The standard 10" bar takes 40 drive links. Note: EGO also sells a separate PS1000 pole saw with a different 1/4" pitch chain — check your exact model number, as PSA1000 and PS1000 are easily confused.

How many drive links is an EGO PSA1000 chain?

40 DL on the standard 10" bar. The DL count is usually stamped on the bar itself, or count the drive links on your old chain. You can also use our Search by Chainsaw tool.

Is this a genuine EGO chain?

No — it's an Alpine Chain Co. chain manufactured to fit the EGO PSA1000, replacing the EGO AC1000 chain and matching the Oregon 90PX. Same pitch, gauge and drive link count, with a semi-chisel profile chosen for Australian hardwood. 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 EGO PSA1000, 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.
