A step up from the MS 230, the MS 250 is light enough to move through smaller tasks like clearing or cleanup but packs a powerful enough punch to cut through small limbs and trees. A combination of features and a high power-to-weight ratio makes this one of the best homeowner chainsaws on the market. Available with 14″/35cm, 16″/40cm or 18″/45cm guide bars.

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.
Side-mounted chain tensioning makes it easy to tension the chain safely.
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.
Precisely calculated buffer zones minimise 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.
Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.
All important functions such as start, choke, throttle and stop are operated via a single lever.
Special caps to open and close the tank cap quickly, easily and without tools.
