Emissions are cut by 70% and fuel consumption is up to 20% lower compared to a STIHL 2-stroke engine of the same power output without 2-MIX technology.

Extend your domestic warranty from 2 to 3 years with the purchase of 5 litres of STIHL MotoMix® fuel and this product. Your STIHL Approved Dealer will register your extended warranty on the STIHL warranty database at point of purchase.


Instruction is necessary to recognize or assess the dangers of a chainsaw. Please wear protective clothing and equipment.
If anything is unclear, we recommend to order the chainsaw via Click & Collect and pickup up the chainsaw from a STIHL servicing dealer.

You can find videos showing you how to fill your machine with fuel and oil, fit bars and chains and start your chainsaw here.

Features

MS 251 C-BE

Standard features

  • Anti-vibration system Zoom
    Anti-vibration system

    Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

  • 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.

  • 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.

  • Ematic chain lubrication system Zoom
    Ematic chain lubrication system

    The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL Oilomatic saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.

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

    A genuine advance in easy starting. STIHL ErgoStart (E) cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. All it takes is 2 fingers and a gentle pull action.

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

    After releasing the sprocket cover the chain can be adjusted using a thumb wheel without the need for tools.

  • Tool free filler caps Zoom
    Tool free filler caps

    Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.

    • STIHL Smart Connector Zoom
      STIHL Smart Connector

      STIHL connected is a smart fleet management system that enables professional users to digitally manage machine fleets and work assignments.

      This is managed by the STIHL Smart Connector - a sensor with a diameter of just under 5cm, which is mounted on the tool. It can be mounted on petrol, electric or battery-powered tools where it records and saves the operating hours while the motor is running and transmits this information via Bluetooth® 4.2 to the STIHL connected App (the smart connector can be mounted on non-STIHL tools too). The Smart Connector offers entirely new functions and services, as a basis for device management both in your home garden using the STIHL connected App, and for managing your machine fleet using the STIHL connected Portal.

      Here’s a few reasons why STIHL connected can help manage your fleet of tools:

      • The Digital Fleet Management keeps a record of all tools and their service record
      • You get prompts when a tool needs servicing, so you never forget to change the plug, filter or just carry out maintenance
      • You can see how many hours a tool has done, so you can plan which tools to use, replace or buy more of
      • At the end of the day, you can open the app and see which tools are next to you - so you can tell if something is missing
      • Book a service with your nearest STIHL Approved Dealer and give them access to see what work will be needed in advance.

      STIHL Connected is an intuitive way to manage your machine fleet and workload intelligently and efficiently. Visit: STIHL connected FAQs to find out more.
