CatalogueMS 171 - Ideal for general cutting and trimming tasks in the garden.
Standard features
Reduced-emission engine technology:
2-stroke engine with stratified charge. During the flushing process a fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase. This cushion reduces the amount of fuel lost in flushing discharge during the charge cycle. The result? More power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.
Standard features
Advanced combustion technology:
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result: lower consumption and high torque across a broad rpm range.
Standard features
Pre-separation air filtration system:
The long-life air filter system with cyclone air routing ensures that 80% of dust particles contained in the sucked in air are caught in the first stage of the system. Unlike traditional systems, these are not collected in the foam filter, but are separated and transported out into the surrounding air. In turn, this provides the elimination of cleaning intervals for the foam pre-filter.
Standard features
Anti-vibration system:
Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.
Standard features
Tool free filler caps:
Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
Standard features
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.
Standard features
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 up to 50%.
Standard features
Side chain tensioner:
The tensioning screw reachable on the side of chainsaw through the sprocket cover. This removes the need for contact with the sharp saw chain.
Standard features
Single-lever master control:
All important functions such as start, choke, throttle and stop are operated via a single lever.
Additional features
Chain Quick Tensioning (B):
After releasing the sprocket cover the chain can be adjusted using a thumb wheel without the need for tools.
Additional features
ElastoStart:
STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.
One of a new generation of occasional use saws, the MS 171 STIHL chainsaw features reduced-emission engine technology — an advantage for the user because it reduces fuel consumption while reducing exhaust emissions. This innovative chainsaw is just right for homeowners who need to cut firewood, fell small trees or do clean up.
