MS 171 STIHL chainsaw

By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

STIHL has developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

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.

Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.

STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems.

Reduced-emission engine technology - more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines
