MS 151 C-E Chainsaw

Lightweight back handle saw for pruning and carving

The lightest back handle saw by STIHL. Suitable for pruning, snedding, hedge-laying and cutting smaller limbs.

This upgraded version of the MS 151 features a new 2-MIX engine that consists of a new cylinder, piston and exhaust. These changes mean there is an increase in power of the saw by up to 1.05kW and a 15% increase in torque to 1.1Nm - all while retaining the lightweight nature of the saw.

Fitted with a manual fuel pump and STIHL's ErgoStart (E) technology, this saw is easy to start-up so you can get on with the job straight away.

Available with either a 10" or 12" bar and fitted with a 1/4" PM3 saw chain for a finer, precise cut. Also excellent for intricate woodwork when combined with a carving bar.

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.

    Standard features

    • 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.

    • STIHL 2-MIX-Engine

      1-in-4 channel technology. The economical STIHL 2-MIX engine with 1-in-4channel technology features a high torque over a wide speed range. The chainsaw provides fuel savings of up to 20% compared to STIHL two-stroke engines in the same performance class without 2-MIX technology. Exhaust emissions are reduced by up to 50%.

    • Manual fuel pump (Purger)

      A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

    • Side chain tensioner

      The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.

    • Tool free filler caps

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

    • Service-friendly air filter system

      The carburetor can be accessed without tools, so you can clean the air filter in a single step.

    • 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.

    • 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.

    • 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%.

    • Advanced combustion technology

      Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.

    • STIHL Smart Connector

      STIHL Connected is a cloud based 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. The STIHL connected Portal gives you a detailed overview of the status of your fleet of tools, as well as information such as duration of use on a particular work assignment.

      You can view power tool availability, analyse machine usage; plan and manage work tasks with associated resources; and analyse machine data, which you can then use to optimise your daily work processes. The Smart Connector also provides information about upcoming tool maintenance and, if needed, the system can arrange a workshop appointment directly with a STIHL Approved Dealer. Service-related tool data can also be shared with the dealer with your permission, so they can plan the servicing work in advance and order any necessary spare parts. This can shorten service times so the tool is quickly ready for use again.

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