Features

MS 500i

Standard features

  • STIHL 2-MIX Engine Zoom
    STIHL 2-MIX Engine

  •  HD2 filter with radial seal
    HD2 filter with radial seal

    The new HD2 air filter, made from PET material and featuring a radial seal, prevents the intake of fine dust particles. The hermetic seal increases the service life of the engine and reduces wear.

  • 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.

  • STIHL ElastoStart Zoom
    STIHL ElastoStart

    STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.

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

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

  • Tool free fuel caps Zoom
    Tool free fuel caps

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

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

    Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.

  • Captive bar nuts Zoom
    Captive bar nuts

    Bar nuts held captive in the sprocket cover will not get lost when changing over the cutting attachment.

  • Optimised sprocket cover
    Optimised sprocket cover

    The flatter, narrower sprocket cover with integrated slide rails reduces effort when pruning and ensures outstanding chip removal.

  • STIHL Ematic with new oil pump system

    The new oil pump system allows a higher volume of oil to be delivered. This is especially useful in dusty conditions or when using a long guide bar.

  • STIHL Injection (i)
    STIHL Injection (i)

    STIHL injection technology enables the MS 500i to achieve extremely high performance with extraordinarily low displacement and low weight. The saw uses innovative technology to achieve rapid acceleration from 0 to 100 km/h in an unbelievable 0.25 seconds. The powerful saw is ready to use right away. Sensors measure air pressure and internal and external temperature, and pass information on to the control unit. This can use the identified values to determine the optimum fuel quantity and ignition timing.

  • Best power-to-weight ratio
    Best power-to-weight ratio

    Its revolutionary chainsaw engine technology, and resulting intelligent lightweight construction result in the best power-to-weight ratio on the market. The optimised design – with lightweight sprocket cover, more compact engine unit, flywheel with a low design height, and a reduced-weight crankshaft adapted to the low weight of the flywheel – makes work significantly more comfortable. The MS 500i is ideal for heavy timber felling, cutting into lengths, and pruning.

  • Very easy to start, whether starting from cold or
    Very easy to start, whether starting from cold or

    The starting process is perfect, with no need for a start position, and easy access to the purger.

  • Sensor-controlled fuel metering
    Sensor-controlled fuel metering

    In addition to the external temperature sensor, the MS 500i also has a pressure and internal temperature sensor in its engine. This measures the environmental pressure on start-up, and during operation it checks the engine temperature and pressure in the crankcase. The electrical voltage generator delivers the required speed information. The control unit processes these values, meaning that the system adapts to the conditions of use. The fuel is then dosed at the optimum level, quickly resulting in perfect running characteristics.

  • Plunge guide
    Plunge guide

    Marking has been added to the fan housing to assist with plunge cuts. This ensures better directional control and safe use of the machine during plunge cutting.

  • Optimised bumper spikes
    Optimised bumper spikes

    The tooth length of the bumper spikes has been adjusted to account for the radial contours of trees. The saw bites into wood even better when cutting lengths and felling.
