Stihl KM131R Professional Kombi Engine gives a great performance throughout the day at long lengths of duration due its 1.9hp 4-mix engine technology provides fast acceleration and more power.Its reliable to start every time in any weather condition and having a simplified starting system to make easy to use with no headache before you start your task. Its great to transport with the split shaft and ideal to be able to carry the engine and attachments in a Stihl carry holder or to fit in your car boot. I have explained in the video below the technic on how to start the KM111R kombi Engine which has the same concept as the KM131R

Standard Features and Benefits:

Manual fuel pump
The manual fuel pump makes starting the tool easier. Pressing the pump ensures fewer strokes are required to start the tool as sufficient fuel is present within the carburettor.
Loop handle (R)
The loop handled grass trimmers and brushcutters are ideal for working in areas where space is limited, e.g. thinning between bushes and shrubs.
Multi-function handle with stop button
All the engine controls can be controlled with just one hand featuring a stop switch which automatically reverts back to the start position for a quicker, simple restart.
STIHL 4-MIX® engine
You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX® engine, which runs on a fuel-oil mix just like a 2-stroke, offers the benefits without the compromises of 4-stroke power. STIHL 4-MIX engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly, quietly and more easily.
Air filter with long service life
The easily accessible paper filter with a long service life means it can go for long intervals without changing.
Stop switch
The multi-function control handle features a stop switch which automatically reverts back to the start position for a quicker, simple restart.
Anti-vibration system
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
Decompression system
The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.
Quick-release coupling
The quick-release coupling allows the KombiSystem to be quickly dismantled into two parts for easy transport and storage – and then re-assembled quickly without tools.
