Compatibility and Inclusions
This listing is for the FS-MM attachment with AutoCut 25-2 head. The MultiEngine is sold separately. The FS-MM is a MultiSystem tool, not an FS-KM KombiTool; do not assume it fits KM petrol KombiEngines or KMA battery KombiMotors.
Before purchase, confirm that your exact MultiEngine model is approved for the FS-MM. Read both the engine and attachment manuals for fitting, gearbox orientation, starting and safe operation.
Cutting Heads and Guards
Use only the exact cutting-head and deflector combinations approved for the FS-MM and your MultiEngine. A shared head brand, thread or family name does not establish compatibility. Check the full head model and mounting requirements before ordering a replacement or alternative.
Do not treat this attachment as approval for a metal grass blade, brush knife, saw blade or a universal blade-fitting kit. Keep the correct deflector fitted, stop the engine and follow the manual before replacing cutting equipment, clearing blockages, cleaning or servicing.
