MS 291 C-BE petrol-driven chainsaw

MS 291 C-BE petrol-driven chainsaw
Powerful and comfortable for longer periods of work Strong, robust 2,8kW petrol chainsaw with fast chain tension (B) and Easy2start (E). Up to 20% less fuel consumption and up to 50% reduction in emissions compared to the same performance STIHL two-stroke engines without 2-Mix technology. Long-term air filtration system with pre-separation. Professional anti-vibration system. Practical all-rounder for farmers, landscape gardeners, construction workers and carpenters. HD2 filter
INCREASES SERVICE LIFE. 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.
Long-life air filter system for chainsaw
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.
Stihl four-chnnel technology
FOR LOWER FUEL CONSUMPTION AND HIGH PERFORMANCE. 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.
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.
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.
Side-mounted chain tension
FOR SIMPLE AND SECURE RE-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.
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 Easy2start
EFFORTLESS STARTING. STIHL Easy2start saves you energy when starting your power 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.
Tool-free fuel cap for oil and fuel tank
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 2-MIX Engine
The STIHL 2-MIX engine is both powerful and economical. Separating the exhaust emissions from the unburnt gas minimises scavenging losses, and therefore increases the power output while reducing consumption.

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.
