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)
-
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.
-
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 and thus reducing fatigue.
-
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.
-
Multi-function handle
All the engine and speed controls are easily accessible and at your finger tips.
-
Tool-free handle adjustment
The handle bar can be easily adjusted to suit the users working position via the tool-free handle adjustment clamp.
-
ADVANCE Universal Harness
Soft padding makes work more comfortable during longer jobs.
-
Stop switch
The multi-function control handle features a stop switch which automatically reverts back to the start position for a quicker, simple restart.
