Features

MS 251 C-BE

Standard features

  • STIHL ErgoStart (E) Zoom
    STIHL ErgoStart (E)

    A spring between the starter cord reel and crankshaft relieves the strain when starting, meaning that excessive pulling on the cord is no longer needed. The result is a convenient starting procedure with practically.

  • STIHL Quick Chain Tensioning (B) Zoom
    STIHL Quick Chain Tensioning (B)

    With STIHL Quick Chain Tensioning, it's easy to adjust the saw chain, without tools and without coming into contact with the sharp saw chain itself. Just release the sprocket cover and turn the adjusting wheel to set the optimum tension.

  • Pre-separation air filtration system Zoom
    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.

  • Compensator Zoom
    Compensator

    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.

  • Manual fuel pump (Purger) Zoom
    Manual fuel pump (Purger)

    STIHL chainsaws and pole pruners with manual fuel pumps allow improved starting with a reduced number of starting pulls. Pressing the primer fills the carburettor control chamber with fuel. This ensures that there is sufficient fuel present to create an ignitable air-fuel mix on starting, requiring significantly fewer starting pulls.

  • STIHL anti-vibration system Zoom
    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 Zoom
    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 Zoom
    Single-lever master control

    All important functions such as start, choke, throttle and stop are operated via a single lever.

  • Tool free fuel caps Zoom
    Tool free fuel caps

    Special caps to open and close the tank cap quickly, easily and without tools.
