MS 251 C-BE Petrol Chainsaw: Top range domestic saw, the optimum choice for property maintenance
The new MS 251 C-BE featuring Quick Chain Tensioning (B) and ErgoStart (E) is ideal for a variety of applications, from cutting firewood to timber construction. This high torque engine is easy to start and comfortable to use, with a high cutting performance. Emissions are cut by 70% and fuel consumption is up to 20% lower compared to a STIHL 2-stroke engine of the same power output without 2-MIX technology.
Extend your domestic warranty from 2 to 3 years with the purchase of 5 litres of STIHL MotoMix® fuel and this product. Your STIHL Approved Dealer will register your extended warranty on the STIHL warranty database at point of purchase.
Instruction is necessary to recognize or assess the dangers of a chainsaw. Please wear protective clothing and equipment.
If anything is unclear, we recommend to order the chainsaw via Click & Collect and pickup up the chainsaw from a STIHL servicing dealer.
You can find videos showing you how to fill your machine with fuel and oil, fit bars and chains and start your chainsaw here.

Features
The pictures shown are sample photos. The actual appearance of the equipment features and their specific attachment to the product may differ from the pictorial representations, but will have the same functionality.
STIHL ANTI-VIBRATION SYSTEM
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.
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.
COMPENSATOR
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.
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.
STIHL ERGOSTART
EFFORTLESS STARTING. STIHL ErgoStart saves you energy when starting your tools. A smooth and even pull on the starter cord is all that’s needed. The required speed on the starter cord is significantly reduced, and the engine starts quickly and reliably even with a slow pull. An additional spring between the crankshaft and the starter cord roll makes this easier.
STIHL QUICK CHAIN TENSIONING
RE-TENSION THE SAW CHAIN TOOL-FREE. Thanks to STIHL Quick Chain Tensioning, you can tension your saw chain quickly and without tools, thanks to the adjusting wheel. Turning the adjusting wheel to the left releases tension on the saw chain, and turning the adjustment wheel to the right tensions the saw chain. The guide bar will be automatically secured when you tighten the sprocket cover.
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.
