STIHL MS 400 C-M Professional 50cm/20″ Petrol Chainsaw (1140-200-0786)

Thanks to the magnesium piston developed in-house by STIHL, the innovative STIHL MS 400 C-M petrol chainsaw offers a range of advantages for forestry professionals. Thanks to the reduced weight of the piston and the lightweight overall construction, this chainsaw has a power-to-weight ratio of 1.45 kg/kW.

But when it comes to felling, delimbing and processing wood in medium-density forests, we know it is not just power that is important. That’s why the advanced version of the STIHL MS 400 C-M chainsaw is equipped with STIHL M-Tronic to enable you to work efficiently. This version also allows for calibration of the system. STIHL ElastoStart supports you when you start your chainsaw, making start-up particularly easy, while the STIHL anti-vibration system reduces vibrations to protect your muscles and joints,. The STIHL MS 400 C-M petrol chainsaw features a long-life air filter system to ensure uninterrupted operation for as long as possible. This consists of a routing pre-separator and an HD2 filter.

Features:

• STIHL Anti-Vibration System
  Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.
• Captive Nuts
  The nuts are attached to the sprocket cover in a captive manner. This makes it impossible for the nuts to fall off and get lost when the cover is removed.
• Manual Decompression
  The decompression valve makes it easier to start your power 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.
• HD2 Filter
  The HD2 filter protects your power tool’s engine against even the finest dust, ensuring a longer service life and reduced wear. The filter made from PET material has up to 70% finer pores than fleece and polyamide filters, and is also oil- and water-repellent. This also makes it easier to clean the filter. When needed, the filter cartridge can be easily replaced without tools.
• Compensator
  The compensator is a control system in the carburetor, 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 With the STIHL M-Tronic, you have the best performance from your implement right from the start. The fully electronic engine management regulates the ignition point and fuel metering in every work situation, taking into account external conditions such as temperature, altitude and fuel quality.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.
• Long-Life Air Filter System for Chainsaws
  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.
• Magnesium Piston
  The extremely lightweight magnesium piston gives you an excellent power-to-weight ratio, allowing you to work highly efficiently and enjoy a long service life. In addition, a chainsaw with a magnesium piston is designed for a high maximum speed.
• Controlled-Delivery Oil Pump
  The controlled-delivery oil pump reduces your chainsaw’s oil consumption by up to 50%. To use it, simply select the E position. For very long cutting attachments or very dry wood, an additional oil volume can be set by the user.
• STIHL M-Tronic
  With the STIHL M-Tronic, you have the best performance from your implement right from the start. The fully electronic engine management regulates the ignition point and fuel metering in every work situation, taking into account external conditions such as temperature, altitude and fuel quality.
• STIHL Four-Channel Technology
  Thanks to STIHL four-channel technology, you can work with your power tool with very low fuel consumption and high performance. The four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted and more compressed manner, which optimally burns the fuel and significantly increases the performance of the engine.
• Side-Mounted Chain Tensioning
  Side-mounted chain tensioning allows for protected, easy and quick chain tensioning and replacement. The tensioning screw is inserted laterally through the sprocket cover.
• STIHL 2-MIX Engine
  The two-stroke engine with STIHL 2-MIX technology saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
• Tool-Free Cap for Fuel & Oil Tanks
  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.
• STIHL Ematic System
  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.
