Stihl MS 500i Chainsaw

Professional petrol chainsaw 63cm/25'' bar

Innovative new chainsaw with electronically controlled fuel injection.

First ever chainsaw with STIHL Injection Technology. The best power-to-weight ratio on the market, and the simplest operation. Ideally suited for the harvesting and processing of large timber. All thanks to its unique lightweight design and outstanding acceleration. New bumper spikes, HD2 filter, captive nut on the sprocket cover for easy chain change, controlled-delivery oil pump, and tool-free fuel cap for safe and easy filling with fuels and lubricants. Where required, there is also the option of the MS 500i W variant with heated handles, which features no-maintenance, wear-free heating strips on the front and rear handles. These keep your hands warm, your grip strong, and operation safe in winter conditions.

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‚ÄČin 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.

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.

Controlled-delivery oil pump

The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.

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 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.

Very easy to start, whether starting from cold

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