The Stihl MS400 C-M is availble from Masseys and is on show in our store in Swadlincote. It is the world’s first chainsaw with a magnesium piston. What does this mean? Well it gives the chainsaw an excellent power to weight ratio. The Stihl MS400 C-M chainsaw has been designed for a professional, offering Stihl’s highest performance in the 60cc class. If you compare the MS400 C-M to the Stihl MS362 C-M, you will see more displacement, more power, more torque and only a small weight increase with an outstanding power to weight ratio. The chainsaw has been designed for felling, de-limbing and cutting timber down to size.
The new Stihl 2-MIX engine provides 4 kW of power, compared to 3.5kW in the MS 362 C-M, as well as more torque – 4.1 Nm vs 3.5 Nm. These increases come from larger displacement of 66.8cc, which is a 14% increase compared to the MS 362 C-M. The magnesium piston is also 14% lighter than the aluminium piston in the MS 362 C-M, helping ensure rapid acceleration.
Thanks to these new and exciting design features, the Stihl MS 400 C-M has an impressive power-to-weight ratio of 1.45 kilograms per kilowatt, making it ideal to use when working in the forest, especially over prolonged periods. The power head on it’s own weighs 5.8 kg. In addition to the new 66.8 cc engine, the MS 400 C-M features STIHL’s latest M-Tronic 3.0 technology which has STIHL’s simple re-calibration procedure and an improved HD2 filter, which all help deliver optimum performance from the saw at all times.
The Stihl MS400 C-M also features Elastostart technology that enables effortless starting of the tool. Designed for forestry and arb professionals, the MS 400 C-M can be used for a range of applications, including felling, de-limbing and cutting timber down to size.
Masseys assemble your chainsaw, PDI it and make sure it is running before you leave the store which will reduce any unwanted down time. Don’t forget, Masseys in Swadlincote, Derbyshire has one of the largest Stihl displays in the UK!
Stihl MS400 C-M Features – Masseys
STIHL M-Tronic (M)
This fully electronic engine management system adjusts ignition timing and fuel metering in all operating modes. It also takes external conditions such as temperature, altitude and fuel quality into account. It ensures consistent engine performance, a constant maximum speed and superb acceleration. M-Tronic makes manual carburettor adjustments unnecessary. Thanks to electronic cold/warm start recognition, now there is only one start position on the combi-lever. The engine starts after fewer pulls and with no change of position, and can immediately accelerate up to speed – even after a cold start. M-Tronic also remembers the settings from the last time the tool was used. So when external conditions are the same, optimal engine performance is available every time you start up again.
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%.
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.
The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.
STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user’s joints and muscles through a spring or rubber element in the starter handle.
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.
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.
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.
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.
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.
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.
When changing the cutting attachment, you will not risk losing the nuts on the sprocket. The MS 261 is the first STIHL chainsaw to be equipped with the captive nuts. A great advantage for all users.
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%.
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.
