Stihl KM 131 Kombi Engine

Standard Features

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.

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.

Bike Handle

When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas, thus reducing fatigue.

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.

The engine requires a mix of petrol and engine oil.  Simply mix a Stihl 50:1 two-stroke engine oil with unleaded (95 octane) petrol. The simplest method is using a standard 5 litre fuel canister and to add 0.1 litres (100 ml) of Stihl HP 2 stroke oil, close and thoroughly shake the canister and the mix is ready to use.

For this machine we recommend either Stihl HP or Stihl HP Ultra engine oil.
