MS 400 C-M Petrol Chainsaw

STIHL M-Tronic

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.

STIHL Anti-Vibration System

FOR MORE PLEASANT WORK. Vibrations can occur when you put your power 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 power tool is more comfortable to hold and your work is much less tiring.

Manual Decompression

EFFORTLESS START-UP. 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.

Long-Life Air Filter System for Chainsaws

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.

Controlled-Delivery Oil Pump

The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.

Side-Mounted Chain Tensioning

The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.

Heated Carburettor (V)

FOR RELIABLE OPERATION EVEN IN WINTER. Thanks to carburettor preheating, you can work reliably with your chainsaw even in winter. You can change the operation from summer to winter mode in just one simple step. In the winter setting, pre-heated intake air flows around the carburettor, preventing it from icing up.

Tool-Free Fuel Cap for Oil and Fuel Tanks

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.

STIHL Ematic System

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.
