WORLDS FIRST CHAINSAW WITH FUEL INJECTION 

 

The innovative MS 500i chainsaw from STIHL 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.

 

The MS 500i 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.

STIHL INJECTION


HIGH PERFORMANCE IN COMPACT DESIGN. The electronic fuel injection control unit calculates the correct fuel supply and ideal ignition time, injecting directly into the crankcase. Sensors measure air pressure and temperatures, allowing the control unit to optimize fuel quantity and ignition timing for more power from a similar weight and size.

 

MANUAL DECOMPRESSION

 

EFFORTLESS START-UP. The decompression valve makes starting easier by allowing some compressed mixture to escape from the cylinder. This reduces the force needed on the starter cord and protects the start-up system.

 

SENSOR-BASED FUEL MEASUREMENT

 

FOR OPTIMISED RUNNING CHARACTERISTICS. Pressure and temperature sensors measure fuel during work, enabling the control unit to adapt to operating conditions. Optimized fuel measurement ensures the best running behavior.

 

SIMPLIFIED START

 

NO NEED FOR A START POSITION. With electronic fuel injection, your chainsaw doesn't need a start position. The accessible manual fuel pump further simplifies the start-up process.

 

STIHL 2-MIX ENGINE

 

HIGHLY POWER-EFFICIENT. The STIHL 2-MIX engine reduces exhaust emissions and fuel consumption, cutting operating costs. This low-maintenance 2-stroke engine uses a petrol and engine oil mixture and meets EU Stage V emissions directives.

 

STIHL ANTI-VIBRATION SYSTEM

 

FOR MORE PLEASANT WORK. Buffer and spring elements in the STIHL anti-vibration system reduce engine vibration transmission to the handle. This makes your tool more comfortable to hold and your work less tiring.
