Small and simple, the MS171 chainsaw can be used by even a novice gardener.

If you are looking for a convenient petrol chainsaw for all those gardening tasks, then the MS 171 really is the one to buy. Ticking all the boxes, it’s great for cutting down small trees, sectioning firewood, reducing bushes and shrubbery and other small sawing tasks.

Additionally, it’s super simple to control with all the operation controlled by a single lever which adjusts the starter, choke, throttle and stop. Manoeuvring the chainsaw is effortless too, being a featherweight at just over 4 kilos, will help reduce fatigue for long periods of use. Around the chainsaw is a loop-handle grip to ensure maximum control and reduce kickback.

Furthermore, Stihl has introduced an anti-vibration system to the MS171 which dampens the oscillations through the chainsaw and into the handle. This helps prevent the long term effects of stress when using power tools in the fingers and wrists. Even the starting process is less stressful, featuring the Stihl ElastoStart system, which reduces compression shock..

A highly efficient petrol chainsaw, for all year round use.

Stihl has designed this MS 171 domestic chainsaw with efficiency in mind. Benefitting from a highly powerful 2-stroke petrol engine with a 2-mix system, it results in a 20% lower fuel consumption and greatly reduced emissions compared to other 2-stroke models.

What’s more, the fuel and air ratio is controlled by an advanced compensator. This prevents the carburettor’s fuel-air mixture becoming rich in petrol and the air filter becoming clogged. Only the right amount of fuel is delivered depending on the volume of air being sucked in, resulting in constant engine power. This Stihl chainsaw also benefits from a pre-separation air filtration system, which means longer filter life.

Finally, Stihl has produced the MS 171 chainsaw with its Ematic chain lubrication system. To make the chains last longer and reduce friction, the system lubricates the saw chains links and guide bar rails, resulting in less wear and up to 50% less oil consumption.
