Stihl Chainsaw MS 251 C-BE

Compact 2.0 kW chainsaw. Up to 20% less fuel consumption and up to 70% emission reduction compared to the same power STIHL two-stroke engines without 2-Mix technology. With optimum control behavior and ease of use. Ideal for the plot.

FEATURES

Reduced-emission engine technology
2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

Pre-separation air filtration system
STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.

Anti-vibration system
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles.

Chain Quick Tensioning (B)
After releasing the sprocket cover the chain can be adjusted using a thumb wheel without the need for tools.

Tool free filler caps
Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.

Ematic chain lubrication system
The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.

Manual fuel pump (Purger)
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

Single-lever master control
All important functions such as start, choke, throttle and stop are operated via a single lever.

STIHL ErgoStart (E)
A genuine advance in easy starting. STIHL ErgoStart (E) cuts the effort required to start the tool by half, while the starter cord can be pulled at just one-third of the normal force. All it takes is 2 fingers and gentle pull action.
