STIHL MS400.1 20" Petrol Chainsaw

The redesigned STIHL MS 400.1 stands at the forefront of chainsaw innovation, offering an exceptional power-to-weight ratio that is critical for demanding tree felling, delimbing and wood preparation tasks. Designed specifically with professionals in mind, its lightweight yet high-performing nature makes it an indispensable tool for ensuring safety and efficiency on job sites.

Delivering a robust 3.9kW output and an impressive 4.3 Nm of torque, the MS 400.1 provides the precise control needed when cutting large timber. Its advanced M-Tronic technology ensures rapid acceleration and a swift start-up, minimising delays and enhancing productivity during critical operations.

With a re-engineered rear handle and a widened gripping area, this chainsaw has been crafted to reduce operator fatigue and provide a secure hold even during prolonged use. The improved design, including a securely positioned leg-rest for plunge cutting, ensures that tree surgery professionals can work with comfort and confidence, even under challenging conditions.

A larger magnesium flywheel paired with an improved muffling system keeps the engine cool under heavy use, while the state-of-the-art HD2 filter extends maintenance intervals. This reliable performance is essential for professionals who must keep downtime to a minimum, ensuring that every cutting task is completed efficiently and to the highest standards.

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.
