Stihl MS 231
The versatile MS231 chainsaw is ideal for private users or farmers felling small trees, cutting firewood and general landscape maintenance. The STIHL 2-MIX engine allows emissions to be cut by up to 70% and up to 20% lower fuel consumption compared to a STIHL 2-stroke engine of the same power output without 2-MIX technology.
Pre-separation air filtration system
STIHL 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.
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.
STIHL anti-vibration system
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.
STIHL Ematic System
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.
Single-lever master control
All important functions such as start, choke, throttle and stop are operated via a single lever.
Side-mounted chain tensioning
Side-mounted chain tensioning makes it easy to tension the chain safely.
Tool free fuel caps
Special caps to open and close the tank cap quickly, easily and without tools.
