STIHL 4-MIX ENGINE
FOR FANTASTIC ENGINE POWER WITH LOW MAINTENANCE. The STIHL 4-MIX® engine is a four-stroke engine that does not require any oil circuit components, thanks to refuelling with an oil and gasoline mix. That’s why it’s more compact, more lightweight, and requires less maintenance than conventional four-stroke engines, while at the same time being powerful and offering a comfortable sound pattern. STIHL 4-MIX® engines comply with the European Stage V emissions directive.
AUTOMATIC DECOMPRESSION
EFFORTLESS STARTING. Automatic decompression makes it easier to start the engine. This is because the system automatically opens the intake valve when the engine is started; the opening time of the valve is extended, and as a result the compression pressure is reduced. This significantly reduces the force required on the starter cord.
LONG AIR FILTER SERVICE LIFE
ENSURES LONG CHANGEOVER INTERVALS. Thanks to its long service life, you rarely need to change the easily accessible filter. This saves resources and reduces maintenance effort.
