Retrieved as indexed publisher-source text on 2026-10-26; original PDF returns 404 and was not visually checked.
RPM, frequency and calibration remain unresolved.
These historical values are retained as provisional source notes only; headline power and frequency-specific prime/standby fields remain blank.
Do not use them as a verified selection rating.
The newer catalogue confirms model existence but gives no exact-model mechanical rating table for this designation.
Do not transfer propulsion, project-level electrical outputs, or specifications from similarly named MPI/622 variants.
Current factory production status is unknown; discontinued is the owner-approved catalogue classification, not a manufacturer-confirmed end of production.
