Product Description

The STIHL MS 251 C-BE petrol chainsaw is the ideal chainsaw if you are undertaking extended sawing tasks, such as harvesting firewood. It is compact and robust and comes with a range of comfort functions that make your job easier, both in domestic tasks and work by skilled trades. The STIHL MS 251 C-BE chainsaw impresses with its high cutting performance and durable STIHL .325 RM3 saw chain. Even thick tree trunks can be effectively felled and processed with the optional 40 cm bar.

Thanks to single-lever control you can control the essential functions of the STIHL 2.2 kW (3.0 hp) 2-MIX engine, such as starting and stopping the power tool, with one hand. This allows you to operate the chainsaw comfortably and safely, as it means your right hand can always remain on the handle. To protect your joints and muscles, the STIHL anti-vibration system reduces engine and power tool vibrations. Starting the chainsaw is easy, because STIHL ErgoStart reduces the effort required by half compared to conventional STIHL starters. The manual fuel pump also allows you to quickly restart the machine after a break in operation. To do this, press your thumb on the pump to feed fuel directly into the carburettor.

To ensure that you can work as comfortably as possible, the STIHL 251 C-BE chainsaw comes with additional features such as STIHL Quick Chain Tensioning, which allows you to re-tension the saw chain easily, safely and without tools, tool-free fuel cap, and pre-separation routing which keeps coarse particles away from the filter.

To additionally protect the engine from fine dust, you can also retrofit this petrol-driven chainsaw with an HD2 air filter, meaning that your STIHL MS 251 will benefit from a long-life air filter system.

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.
