The Stihl KM111R Kombi Engine with it’s newly updated 4-MIX engine, replaces its predecessor (the KM100R), in performance. An easier starting method, a bigger tank for fuel and a larger fuel tank and an easy to handle loop grip operation, are just some of the upgraded additions. Therefore, you can operate the tool longer with less fatigue

Improve productivity with the Stihl Kombi Engine

  • Simpler starting method,
  • A bigger fuel tank at 0.71 Litres,
  • Compatible with the full KombiTools range,
  • Lightweight comfortable operation,
  • High torque, with low noise and vibration.

An upgraded 4-Mix Engine

Benefit from the resilience of a 2-stroke but the power of a 4-stroke engine with the KM 111 R. With the combination of a fuel/ oil mix, the mechanics of the machine much far more smoother than other engine, this means you can enjoy a quiet motor amongst other benefits. Additionally, with smoother operation comes increased efficiency, meaning less fuel consumptopn and reduced emmisions.

Enjoy lightweight operation

All Stihl products come with optimal design for performance, the KM111 R is no different, being lightweight and comfortable to use. It’s also very easy to move around your garden, with a weight of just 4.4kg and an easy to handle loop-handle operation system. One handed use is no issue too as the controls are within reach together from the hand-held bar. Ideal for those tight working areas of your garden or pathway.

Start and restart with no fuss.

An upgrade to the starter feature means a simple but efficient start/ stop functions. Featuring a manual fuel pump, this allows the engine to start with less strokes. Combine this with the decompression valve, less force is required to get it started by pulling the starter rope.

Compatible with all KombiTools

Another great feature of the Stihl KM111R Kombi Engine, is it can be used with the full range of Kombi Tools including blowers, bristle brushes and edge trimmers. With twelve attachments in total, there is a tool for every job, which can all be easily swapped between using the quick release coupling system. Take the weight of and improve productivity with the shoulder harness attachment, perfect for the large working areas to reduce strain.

Features We Like

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. (similar to illustration)

Stop switch

The multi-function control handle features a stop switch which automatically reverts back to the start position for a quicker, simple restart.

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.

Shoulder strap / carrying system

Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.

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.
