Features Continued:
Controlled-Delivery Oil Pump
- Different bar lengths, wood types and sawing techniques require different amounts of oil
- The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand
Compensator
- Controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged
- 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
- Filter doesn't need to be cleaned until an appreciable drop in power occurs
Decompression Valve
- The decompression valve is part of the easy starting system
- Decompression valve is semi-automatic, it must be pressed manually before starting, but then closes automatically
- The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope
Stihl Anti-Vibration System
- The chainsaw therefore runs noticeably smoother
- This allows the user to save their strength and work longer
- Precisely calculated buffer zones minimize the transfer of engine and saw chain vibrations to the front and rear handles
Stihl Ematic System
- Compared to conventional bars without Ematic, the Stihl Ematic system reduces the consumption of chain lubricant by up to 50 percent, 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
- Virtually every drop of chain lubricant is delivered to exactly the right spot
Side-Mounted Chain Tensioning
- Side-mounted chain tensioning makes it easy to tension the chain safely
Captive Nuts
- A great advantage for all users
- When changing the cutting attachment, you will not risk losing the nuts on the sprocket
- The MS 261 is the first Stihl chainsaw to be equipped with the captive nuts
Tool Free Fuel Caps
- Special caps to open and close the tank cap quickly, easily and without tools
