The awsome, innovative STIHL MS 500i petrol chainsaw is the world’s first chainsaw with electronically controlled fuel injection. Its agile, performance-optimised engine accelerates very quickly. Thanks to its extremely successful lightweight design, this tool achieves an impressively low power-to-weight ratio of 1.24 kg/kW. This high-torque machine is a powerful solution for use in professionally harvesting large timber.
Working with the MS 500i means maximum operating enjoyment resulting from powerful performance. The machine features a simple start-up sequence as well as very good starting behaviour under all usage conditions. Sensory fuel metering guarantees that the mixture is directly adapted to the oxygen content of the air. Like the MS 462, this saw can be very easily pivoted and – thanks to its new bumper spikes and sprocket cover – can be guided close to tree trunks.

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