Stihl MS171 14" Petrol ChainsawOne of a new generation of occasional use saws, the STIHL MS 171 chain saw features reduced-emission engine technology. Reducing fuel consumption by up to 20% compared to its predecessor, this innovative saw saves the user both time and money. Ideal for homeowners, the STIHL MS 171 is good for cutting firewood, felling small trees or completing clean up tasks.
Special Features Stihl MS171 14" Petrol Chainsaw:
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. 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
Advanced combustion technology - Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.
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
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.
Tool free filler caps - Special catches on the fuel and oil tanks for easy opening and locking without the need for tools
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 carburettor 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
Ematic chain lubrication system - The Ematic chain lubrication system ensures pinpoint 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%.
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
Single-lever master control - All important functions such as start, choke, throttle and stop are operated via a single lever
Chain Quick Tensioning (B) - After releasing the sprocket cover the chain can be adjusted using a thumb wheel without the need for tools. (Optional, not included).
STIHL ElastoStart - STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle. (Optional, not included).
