Features

Standard features

STOP BUTTON

Simply Set the choke, pump the fuel primer, pull the starter cord and away you go! The running machine then switches off after a brief press of the stop button. Once the machine is at a standstill, the ignition activates again automatically. Thus the ignition is always ready for starting.
Ergonomic bike handle

When used in conjunction with a harness, the bike handle enables a smooth mowing action. Ideal for working on large areas and allows the machine to be easily guided, 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.
Multi-function control handle

Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.
STIHL Anti-vibration system

The STIHL anti-vibration system is available in a one-point version for smaller models and in an especially effective four-point version for larger machines starting with the STIHL. It reduces handle vibration for easy and comfortable operation.
Stop button

You do not need to control the stop button when restarting. The engine can be started at any time.
