This removes the need for contact with the sharp saw chain. Side chain tensioner - The tensioning screw can be found on the side of the chain saw through the sprocket cover. Single-lever master control - All important functions such as start, choke, throttle and stop are operated via a single lever. The Ematic system can reduce bar oil consumption by up to 50%. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. 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.Įmatic chain lubrication system - The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. The pre-cleaned air is routed to the air filter via the pre-separator duct.Īnti-vibration system - Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. The larger, heavier particles are ejected. Pre-separation air filtration system - STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. The filter doesn't need to be cleaned until an appreciable drop in power occurs. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. The result is lower fuel consumption and high torque across a broad rpm range.Ĭompensator Compensator - This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.Īdvanced combustion technology - Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. 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. Reduced-emission engine technology - 2-stroke engine with stratified charge.
