Product Details

Standard Features

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.

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.

Fuel - 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.
