STIHL FSA80

Technical Specifications: Nominal battery system 36 V DC STIHL lithium-ion; EC brushless motor in standard cordless brushcutter configuration; cutting circle and head selected by kit, with line heads such as AutoCut models or reversible grass blades according to regional package; handle options include loop or bike handles depending on FSA 80 variant; tool-only mass and total mass with battery vary by handle, shaft and battery pack; charging through the STIHL charger matched to the installed battery; runtime determined by battery capacity, cutting head, grass density and throttle profile.

Functional Features: Electronic motor control with variable speed according to trigger and ecosystem settings, automatic line feed on compatible AutoCut heads, guard and harness provisions for user safety, low-noise electric operation, and battery state indication through the pack or machine display where fitted.

Application Scenarios: Residential and commercial lawn trimming, garden edge cutting, orchard and amenity grassland maintenance, cemetery and municipal green-space care, and areas where exhaust emissions, noise or manual starting must be avoided.

Performance Parameters: Brushless EC drive provides high starting torque and consistent speed under varying grass load; cutting diameter follows the installed head or blade, commonly 350 to 380 mm for comparable STIHL 36 V brushcutters; vibration and sound values must be taken from the regional nameplate because they change with head, battery and handle kit.

Material Composition: Glass-filled polymer motor housing and guard, aluminum or composite drive shaft according to handle class, steel or nylon cutting attachments, lithium-ion battery cells with electronic protection circuit, and ergonomic grips with anti-vibration inserts where specified.

Structural Characteristics: Straight or curved shaft according to variant, detachable cutting head, guarded spindle, trigger and safety interlock, battery bay or backpack cable interface according to battery system, and adjustable handle geometry for balance.

Working Principle: The lithium-ion battery supplies DC power to the electronic controller, which drives the brushless motor at a commanded speed. Motor rotation is transferred through the shaft to the cutting head; line heads dispense trimming line automatically or manually, while blade heads provide cutting for thicker vegetation.

Installation Requirements: Insert the STIHL-approved battery fully until locked; attach the correct guard for the installed head; adjust handle and harness for upright posture; fit the recommended line diameter or blade; charge the battery with the matching STIHL charger before first use; confirm local regulations for blade use in public areas.

Usage Precautions: Use only STIHL-approved batteries and chargers; disconnect battery before changing line, blade or guard; wear eye protection, hearing protection, gloves and leg protection; keep bystanders clear of the rotating head arc; do not operate with damaged guard, line head or motor housing; avoid wet electrical connections and store battery within the recommended temperature range.
