STIHL MS400.1 18" Petrol Chainsaw

The STIHL MS400.1 is specifically engineered for professionals who demand unrivalled efficiency and reliability in challenging environments. Its re-engineered 60cc platform boasts an outstanding power-to-weight ratio, offering a robust 3.9 kW output alongside 4.3 Nm of torque. This ensures that the chainsaw remains steady when cutting large timber, minimising the risk of bogging down a critical requirement for those working in the field of tree surgery.

With its advanced M-Tronic system, the chainsaw ensures a rapid start-up and quick acceleration. This means less time waiting and more time efficiently tackling felling, delimbing and wood preparation tasks on busy job sites. The seamless performance is crucial for managing multiple challenges, such as adhering to strict health and safety regulations and ensuring minimal equipment downtime.

Understanding the physical demands placed on tree surgeons, the STIHL MS400.1 has been designed with an improved geometry. The rear handle has been refined and the gripping area enhanced to reduce operator fatigue an essential benefit when working long hours in varying weather conditions. This ergonomic focus not only ensures extra comfort but also contributes to safer and more controlled cutting, critical when precision and consistent handling are needed on every job.

Built to maintain optimal operating temperatures even during extended use, this chainsaw integrates a larger magnesium flywheel and an improved muffling system. These features work together to ensure the engine remains cool and efficient, reducing maintenance interruptions. For professionals managing tight schedules, this translates into greater operational efficiency and reliability even in less than ideal working conditions.

Engineered with a compact yet robust design, the STIHL MS400.1 is perfectly suited to the rugged demands of tree surgery. It is built to withstand the pressures of continuous use in challenging outdoor settings, ensuring that the chainsaw remains a dependable tool that meets the rigorous safety and performance standards required by professionals.

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.
