Features

MS 440

Standard equipment

  • STIHL ElastoStart Zoom
    STIHL ElastoStart

    Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element in the ElastoStart special starter grip alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.

  • Carburettor heating (V) Zoom
    Carburettor heating (V)

    By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

  • 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 at hand.

  • Side-mounted chain tensioning Zoom
    Side-mounted chain tensioning

    Side-mounted chain tensioning makes it easy to tension the chain safely.

  • Compensator Zoom
    Compensator

    This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

  • Decompression valve Zoom
    Decompression valve

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

  • STIHL anti-vibration system Zoom
    STIHL anti-vibration system

    Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.

  • STIHL Ematic System Zoom
    STIHL Ematic System

    Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.

  • Single-lever master control Zoom
    Single-lever master control

    All important functions such as start, choke, throttle and stop are operated via a single lever.

  • Tool free fuel caps Zoom
    Tool free fuel caps

    Special caps to open and close the tank cap quickly, easily and without tools.
