STIHL FSS-KM 450mm Line Trimmer (FA03 200 0018)
The STIHL FSS-KM 450mm Line Trimmer (FA03 200 0018) is a KombiSystem attachment for cutting grass along walls, fences, hedges and paths, or mowing areas a lawn mower cannot easily reach. Its 450mm nylon-line mowing circle helps cover ground efficiently.
Attachment Only
A compatible STIHL power unit is sold separately. This is not a complete powered line trimmer or brushcutter. For a battery power unit, battery and charger are also separate unless expressly included in the selected kit.
Key Features
- 450mm nylon-line mowing circle for grass cutting.
- AutoCut nylon-line mowing setup.
- KombiSystem coupling for quick attachment changes.
- Useful around obstacles and on awkward terrain, subject to secure footing and the operating manual.
- Protective shield helps deflect cuttings and debris but does not eliminate thrown-object hazards.
Compatible Power Units
- STIHL KMA 200 R battery KombiMotor.
- STIHL KM 131 R petrol KombiEngine.
- The existing listing also identifies legacy KM 235 for existing owners; confirm the exact combination in its instruction manual.
The current Australian KombiSystem guide lists FSS-KM for KMA 200 R and KM 131 R, not KMA 80 R, KMA 135 R, KM 56 RC-E or KM 94 RC-E. Do not apply standard FS-KM compatibility to FSS-KM. Check the exact attachment and power-unit combination before ordering.
Cutting Head and Replacement Parts
Confirm the exact AutoCut head supplied with part FA03 200 0018 before ordering replacement spools, line or head components. The existing listing identifies AutoCut 27-2 as an optional mowing head, not an additional included head; verify approval for the exact setup before purchase.
Metal-blade configurations require separate approval for the exact FSS-KM, power unit, cutting tool, guard, mounting parts, handle or barrier bar and harness. An FS-KM fitting-kit listing is not proof of FSS-KM compatibility. Ask Betontools to confirm the complete setup before ordering a blade or conversion parts.
Safe Fitting and Operation
Follow both the attachment and power-unit manuals for fitting, protective equipment and operating distances. Stop and isolate the power unit as instructed before changing attachments or working on the cutting head. Maintain secure footing and keep people clear of the cutting area.
