Description
A lightweight, fuel-efficient chainsaw with reduced-emission engine technology.
The STIHL MS 171 is part of the lightweight generation of STIHL chainsaws with reduced emission technology – a significant benefit for users because it saves fuel even as it cuts exhaust emissions. The MS 171 also has the STIHL pre-separation air filter, which can extend filter life up to five times over previous models.

STIHL anti-vibration systemPrecisely calculated buffer zones minimize the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer. |
 |
Reduced-emission engine technology2-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 technologyFour 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 systemSTIHL 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. |
 |
Tool free fuel capsSpecial caps to open and close the tank cap quickly, easily and without tools.
|
 |
Side-mounted chain tensioningThe tensioning screw can be found on the side of chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.
|
 |
Single-lever master controlAll important functions such as start, choke, throttle and stop are operated via a single lever.
