First standard chainsaw with electronically controlled fuel injection
STIHL has launched the MS 500i, which it boasts is the world’s first standard chainsaw with electronic fuel injection and a never-before achieved power-to-weight ratio.
The company says the injection technology (i) not only “provides the chainsaw with incredible torque, but also ensures rapid acceleration of the saw chain from 0 to 100km/h in 0.25 seconds”.
It also says that due to the intelligent lightweight design, the MS 500i features the best ever power-to-weight ratio – 1.24 kilograms per kilowatt, a value never achieved before by series-manufactured chainsaws.
STIHL goes on to say that together with the many additional design optimisations, “there is a substantial increase in operator comfort”. The reduction of gyroscopic forces provides the 80cm³-class high-performance professional saw with dynamic manoeuvrability, which is a particular advantage during limbing. This makes the professional big timber harvester easy to handle in all disciplines – from felling to cutting to length.
This is also supported by the new bumper spike geometry. The raised plunge bar on the fan housing – parallel to the axis of symmetry of the guide bar – makes directional control and tool guidance easier when plunge cutting. Captive nuts on the chain sprocket cover make changing the chain straightforward.
The company says that the MS 500i has “exceptional starting behaviour and provides optimum engine power right from start up”. The engine does not need a carburetor, since the fuel metering is done using a sensor, and automatically adapts to the different operating conditions, no matter what the altitude and ambient temperature.
Due to the exceptional level of interest, the machine will already be available in selected markets, including Germany, in limited quantities in time for the 2018-19 season.
