EGO PS1000 Chain Questions

What size chain does an EGO PS1000 take?

1/4" pitch, 0.043" (1.1mm) gauge on the PS1000. The standard 10" bar takes 56 drive links. Note: EGO also sells a separate PSA1000 pole saw attachment with a different 3/8"LP pitch chain — check your exact model number, as PS1000 and PSA1000 are easily confused despite both being 10" 56V pole saws.

How many drive links is an EGO PS1000 chain?

56 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 PS1000, replacing the genuine EGO chain and matching the Oregon 25AP. 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 PS1000, 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.
