    STIHL M-TRONIC SYSTEM (FT)

    The electronic engine management system with memory function regulates the ignition timing, fuel supply and automatically registers the external temperature allowing optimal engine performance, great acceleration and sustained maximum torque. This technology also provides a simplified starting procedure.

  • STIHL ANTI-VIBRATION SYSTEM Zoom
    STIHL ANTI-VIBRATION SYSTEM

    Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.

  • DECOMPRESSION VALVE Zoom
    DECOMPRESSION VALVE

    The decompression valve is part of the easy start-system. The valve should be pressed before starting in order to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.

  • COMPENSATOR Zoom
    COMPENSATOR

    The compensator is a control system in the carburettor, that uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance, letting you work for a long time without maintenance.

  • STIHL EMATIC SYSTEM Zoom
    STIHL EMATIC SYSTEM

    A reservoir holds bar oil until it is picked up by the passing chain. This achieves maximum lubrication resulting in longer wear and less oil consumption.

  • SIDE CHAIN TENSIONING Zoom
    SIDE CHAIN TENSIONING

    The tensioning screw is located on the side of the chainsaw through the sprocket cover. Chain side tensioning allows the saw chain to be re-tensioned effortlessly, avoiding any contact with the sharp chain.

  • CONTROLLED-DELIVERY OIL PUMP Zoom
    CONTROLLED-DELIVERY OIL PUMP

    Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job.

  • HD2 FILTER Zoom
    HD2 FILTER

    The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from robust PET material and is oil and water-repellent, making it easier to clean the filter. The filter cartridge can also be easily replaced without tools.

  • STIHL 2-MIX ENGINE Zoom
    STIHL 2-MIX ENGINE

    The low-maintenance STIHL 2-MIX engine reduces emissions and fuel consumption while maintaining high efficiency, even at high power levels.
