PRE-SEPARATION AIR FILTRATION SYSTEM
Stihl long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.
>>
REDUCED EMISSION ENGINE TECHNOLOGY
2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. Thie results in more power with a lower weight, up to 20 lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.
>>
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.
>>
COMPENSATOR
This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carbutettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs.
>>
SIDE CHAIN TENSIONER
The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.
>>
EMATIC CHAIN LUBRICATION SYSTEM
The Ematic chain lubrication of the saw chain links and guide bar rails. When used with Stihl Oilomatic saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.
>>
CARBURETOR PREHEATING SYSTEM
For reliable operation even in winter. Thanks to the preheating of the carburetor, you can work reliably with the chainsaw even in winter. You can switch it from summer to winter mode with just one simple step. In the winter environment, preheated intake air flows around the carburetor, preventing it from freezing.
>>
TOOL FREE FILLER CAPS
Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
