STIHL MS 500i Petrol Chainsaw | 63 cm
The world’s first chainsaw with electronically controlled fuel injection
Product description
With the STIHL MS 500i marks a new era in chainsaw technology from STIHL. As the world’s first chainsaw with electronically controlled fuel injection, it sets new standards in performance and responsiveness. With its powerful 79.2 cm³ engine, low weight and dynamic handling, it is ideal for professional large-timber harvesting and processing in forestry.
Common problems
Professional large-timber harvesting presents typical challenges for conventional carburettor saws:
- Manual carburettor adjustment responds only slowly to changes in altitude and outside temperature
- Carburettor engines often require different start positions for cold and warm starts
- With conventional engines, high power usually comes with correspondingly higher weight
Solution
The MS 500i tackles this with revolutionary STIHL Injection: a control unit uses pressure and temperature sensors to constantly calculate the optimum fuel supply and ideal ignition timing – regardless of altitude or ambient temperature, with no start position.
Key features
- High-performance forestry saw with 63 cm RS cutting attachment
- STIHL Injection – electronically controlled fuel injection
- Best power-to-weight ratio on the market: 1.24 kg/kW
- Chain accelerates from 0 to 100 km/h in 0.25 seconds
- Simplified starting with no start position
- Optimised bumper spike for a firm hold on the tree
- Captive nuts on the sprocket cover
- STIHL anti-vibration system for more comfortable working
Highlights
STIHL Injection
The control unit constantly calculates the correct fuel supply and ideal ignition timing. Sensors measure air pressure and internal and external temperature – for consistently optimum performance in all conditions.
Best power-to-weight ratio on the market
At 1.24 kg/kW, the MS 500i achieves the best power-to-weight ratio on the market – unique in its class despite its high output.
Rapid acceleration
The chain accelerates from 0 km/h to 100 km/h in an incredible 0.25 seconds. This means fast progress in professional large-timber processing.
Simplified starting
Thanks to electronic injection, there is no start position. The easily accessible purger further perfects starting, whether cold or warm.
Optimised sprocket cover
Narrower and flatter than on the previous model, with integrated skid strips and guide edge – for less strenuous limbing and excellent chip removal.
Comfortable working
The STIHL anti-vibration system significantly reduces strain on arms and hands during longer forestry work.
