What this is
Two replacement chains for EGO’s Multi-Head pole saw attachment — the PSA1000, the carbon-fiber PSA1020, the MPS1000 / MPS1001 kits built around them — and the commercial PSX2500 attachment. EGO’s own chain for all of these is AC1000. This pack is the same size: 10”, 3/8” low-profile pitch, .043” gauge, 40 drive links.
EGO has two 10-inch pole saw chains
| EGO chain | Pitch | Drive links | Used on |
|---|---|---|---|
| AC1000 | 3/8” low-profile | 40 | PSA1000, PSA1020, MPS1000 / MPS1001, PSX2500 — this chain |
| AC1000Q | 1/4” | 56 | PS1000, PS1001, PSX2510 (our chain for those) |
The quickest way to tell them apart: the PSA attachments clip onto an EGO Power Head (PH1400 or PH1420). The PS1000 is a complete pole saw with its own motor.
Fitting it
The PSA1000 and PSA1020 are tensioned with a chain-tensioning screw, not a tool-free knob. EGO’s manual lists only the AG1000 bar and AC1000 chain as approved accessories and says to use only low-kickback chain on these attachments.
