Product Description

The MS 251 is STIHL’s top range domestic petrol chainsaw ideal for efficiently cutting firewood, felling small trees, timber construction, and general garden maintenance.

High levels of torque are efficiently delivered by this machine’s STIHL 2-mix engine. Despite this, it produces 70% less emissions and uses 20% less fuel than similar standard 2-stroke engines.

The MS 251 also has a lightweight and well-balanced construction, resulting in an impressive power to weight ratio, making this machine easy to position and manoeuvre while still being able to cut thicker material efficiently.

Also, the machine utilises innovative anti-vibration technology to improve comfort and reduce the risk of nerve damage if using for longer periods of time.

Finally, maintenance is made simple with the side chain tensioner, the easy-to-open tool-free filler caps, and the Ematic chain lubrication system.

The STIHL brand is known for its high-quality, reliable chainsaws. That’s why this MS 251 petrol chainsaw features:

  • Excellent power-to-weight ratio (high performance and manoeuvrability)
  • An economical and low-emission STIHL 2-MIX engine
  • Anti-vibration system (reduced injury risk)
  • Single-level master control (start, choke, throttle, and stop)
  • Side chain tensioner (removes need to come into contact with the chain)
  • Compensator (constant engine power)
  • Pre-separation air filtration system (longer filter life)
  • Ematic chain lubrication system (lowers oil consumption by up to 50%)
  • Tool-free filler caps

Reduced-emission engine technology

2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

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

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.

Features in depth

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

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

Side chain tensioner

You can tension the chain quickly with the easily accessible chain tensioner on the side of the machine.

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%.

Tool free filler cap

Patented special filler caps for fuel and oil. These filler caps can be opened and closed again quickly and easily, without tools.
