Description:

Designed for the most demanding tree care and forestry professionals, the STIHL® MS 400 C-M is built with STIHL M-Tronic™ engine technology to deliver low exhaust emission, fuel-efficient performance even under changing conditions. Unlike its aluminum piston-equipped counterparts, the advanced magnesium piston in the MS 400 C-M provides greater displacement, power, and torque without additional weight. A long-life HD2 air filter means you simply clean it instead of replacing it, while a Pre-Separation Air Filtration System removes large debris before it even gets to the air filter, increasing run time between cleanings.

Features:

• Magnesium Alloy Piston – The magnesium alloy piston is lighter in weight than equivalent-size aluminum alloy pistons.
• Excellent Power-to-Weight Ratio (12.8 lbs./5.4 bhp) – Thanks to innovative engineering and construction, the MS 400 C-M delivers an excellent power-to-weight ratio.
• Modern Design – The modern design of the MS 400 C-M is an aesthetic reflection of the power and innovation this saw delivers.
• Lightweight (12.8 lbs.) – The MS 400 C-M professional chainsaw is designed to deliver lightweight performance and jobsite productivity.
• STIHL M-Tronic™ – This product features M-Tronic™, a new generation of Intelligent Engine Management that eliminates the low and high speed carburetor adjustment screws, compensates for dirty air filters, and adjusts to changes in elevation and fuel quality for optimum engine power at all times.
• STIHL ElastoStart™ – The ElastoStart™ starter handle is an exclusive feature of STIHL®. It has a built-in shock absorber that helps reduce effort when pulling the starter cord. The grip noticeably reduces the sudden peak forces felt during cranking.
• Ematic™ Lubrication System – The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, provides proper lubrication with up to 50% less oil consumption than conventional methods.
• STIHL Quickstop® – STIHL® chainsaws are equipped with the STIHL Quickstop® chain brake system designed to reduce injury risk in certain kickback situations by stopping the chain within fractions of a second.
• Winter/Summer Shutter – Allows the carburetor to operate at optimum temperature year-round and helps prevent carburetor icing below 50°F (10°C).
• Adjustable Automatic Oiler – Allows the user to adjust the lubrication for different bar lengths and cutting conditions.
• Translucent Fuel Tank – Lets operators easily check fuel level before starting work.
• Bumper Spikes – Prevent pull-in and improve control during cutting.
• Decompression Valve – Vents cylinder compression for easier starting, reducing effort when pulling the starter rope.
• Pre-Separation Air Filtration System – Boosts engine filter efficiency by removing larger debris before it reaches the air filter, doubling time between cleanings.
• Side-Access Chain Tensioner – Makes saw chain adjustment more convenient with a bar wrench.
• Master Control Lever™ – The Master Control Lever™ is a single, easy-to-use lever that controls choke, throttle lock, and on/off switch.
• Anti-Vibration System – STIHL® has engineered this system to reduce vibration and operator fatigue for more comfortable use.
• Toolless Fuel and Oil Caps with Retainers – Caps can be opened or tightened without tools by lifting and twisting.
• Throttle Trigger Lock – See it in action!
