Stihl MS 271 Light Petrol Chainsaw 14 / 16 / 18 inch

Introducing the new 2020 version of the Stihl MS271 Petrol chainsaw, the ideal for cutting firewood and landscape use. Upgrades include the new .325″ RS Pro saw chain, with an updated Light 04 guide bar – which means an amazing improvement in cutting performance.

• Upgraded bar and chain,
• Better fuel economy
• Lightweight and well balanced,
• Available with a 14″, 16″ or 18″ blade.

MS271 has better cutting performance than previous models

With the Stihl MS 271 Petrol chainsaw, we have seen an impressive 20% increase in cutting performance (compared to .325″ RS). With this petrol chainsaw, you will also not lack power. Designed with a narrower cutting width (kerf), the blade will have less resistance to the wood, therefore, you can saw through at a much greater speed.

Additionally, this Stihl petrol chainsaw will always provide optimum power with a great throttle response. The MS271 is comfortable to use too, with Stihl’s anti-vibration system crucially reducing the judder. This means no more aching hands during long stints.

Unstoppable operation with better efficiency.

After the machine is turned off, the control lever immediately moves back into the operating position. This allows a warm machine to be restarted again immediately.

This controller in the carburettor prevents the fuel-air mixture from 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.

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%.

Features We Like

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%

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.

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.

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.

Combi lever

As M-Tronic has electronic cold and warm start recognition, only one start position is needed on the combi lever. The exact amount of fuel is supplied on demand. You do not need to know about the status of your chainsaw and can apply full throttle straight away – even with a cold start. Because the saw is warmed up by optimum acceleration in a few seconds.

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.

Carburettor heating (V)

By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

Single-lever master control

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

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%.

HD2 filter

The HD2 filter is made from polyethylene filter material with up to 70% finer pores than fleece and polyamide filters to trap even very fine dust. In addition, it is oil and water-repellent and thus very easy to clean. The PET-covered filter cartridge with quick-release lock enables the filter to be assembled and disassembled in next to no time, without using tools.
