STIHL MS400.1 20" Petrol Chainsaw

The redesigned STIHL MS 400.1 is engineered for both professionals and passionate garden enthusiasts. Its redevelopment from the MS 400 C-M means it delivers an extraordinary power-to-weight ratio in the 60cc class, ensuring that felling, delimbing and wood preparation are executed with impressive speed and reliability.

Experience enhanced precision with a redesigned rear handle and widened gripping area. These improvements minimise operator fatigue, making it the ideal tool for long sessions whether you are managing extensive landscaping projects, conducting tree surgery or maintaining your own garden.

Boasting a robust 3.9 kW output and 4.3 Nm of torque, the MS 400.1 ensures consistent performance even under pressure. An integrated M-Tronic system guarantees fast start-up and rapid acceleration, helping you maintain momentum on every task while the larger magnesium flywheel and improved muffle system keep engine temperatures in check.

Designed to thrive in challenging outdoor environments, this chainsaw is equipped with an advanced HD2 filter. It captures fine dust and particles efficiently, reducing maintenance intervals and ensuring that your tool remains reliable throughout demanding ground care, professional landscaping, or intensive garden maintenance.

FOR MORE PLEASANT WORK. Vibrations can occur when you put your tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your tool is more comfortable to hold and your work is much less tiring.

CAPTIVE NUTS. When changing the cutting attachment, you will not risk losing the nuts on the sprocket.

EFFORTLESS START-UP. The decompression valve makes it easier to start your tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.

REDUCES OIL CONSUMPTION. The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.

SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.

REDUCED MAINTENANCE. The compensator is a control system in the carburettor, which uses pressure compensation to ensure that engine performance, exhaust gas quality and fuel consumption remain virtually constant over a long period of time, despite increasing contamination of the air filter. You do not need to clean the air filter until there is a noticeable drop in performance. This means that you can work for a long time without maintenance.

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.

EXTENDED FILTER SERVICE LIFE. Pre-separation routing removes coarse, larger particles from the airstream before they can reach the actual filter. The HD2 filter keeps even fine dust away from the engine, ensuring a long engine service life, long cleaning intervals and easy maintenance of your chainsaw. When we refer to a long-life air filter system in chainsaws, this exclusively describes models that have pre-separation routing and an HD2 filter. With this system, you benefit from a significantly longer filter service life compared to conventional air filter systems.

VARIABLE DISPLACEMENT OIL PUMP. Allows a precise, demand-based delivery of oil. It's possible to reduce oil production by up to 50% in the E position. For very long cutting attachments or very dry wood, an additional volume of oil can be added by the user. similar to illustration.

HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX engine complies with the strict EU Stage V emissions directive.

RELIABLE WORK WITH THE BEST PERFORMANCE. With STIHL M-Tronic, you’ll have the best performance from your work tool from the outset. Fully electronic engine management regulates the ignition timing and fuel metering in all work situations, taking into account external conditions such as temperature, altitude and fuel quality.

QUICK AND EASY TO USE. With tool-free fuel cap, you can open and close oil and fuel tanks in just a few simple steps, thanks to a bayonet closure.
