NOTE
Hitachi LR165-714 — 65 A rating on CG engine. Note: page heading on EL-7009 referenced LR170-714 in the construction exploded view, but the SDS here lists LR165-714. The 165 vs 170 discrepancy is intentional — LR170-714 is the construction reference (mechanical), LR165-714 is the in-service nominal (electrical 65 A) — verify against the unit's own nameplate when ordering parts.
