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.

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.

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)

Manual fuel pump (Purger)

A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

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.

Stop switch

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

Loop handle

The brushcutter loop handle is ideal when working in confined spaces and mowing around obstacles.
