Stihl MS 151 C-E Chainsaw Specs

Technical Features

  • Starting a chainsaw can be a hassle, but STIHL ERGOSTART takes the effort out of the process with a unique feature that includes a spring between the starter cord reel and crankshaft. This innovation relieves the strain of starting, making it easy and convenient to get the saw running.
  • Powered by STIHL 2-MIX engine, this chainsaw is an eco-friendly option that saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines without 2-MIX technology. This not only saves money but also helps preserve the environment.
  • Side-mounted chain tensioning is another feature that makes STIHL ERGOSTART user-friendly. This convenient feature makes it easy to tension the chain safely, reducing the risk of injury or damage to the chainsaw.
  • No more fumbling around with additional tools when it’s time to refill the tank! The tool-free fuel caps on the STIHL ERGOSTART allow for quick and easy opening and closing of the tank cap.
  • The service-friendly air filter system allows for easy access to the carburetor, making it simple to clean the air filter without the use of any tools. This feature saves time and makes maintenance a breeze.
  • The STIHL anti-vibration system is a must-have for any serious chainsaw user. This system features buffer zones that minimize the transfer of engine and saw chain vibrations to the front and rear handles, resulting in a smoother operation and less fatigue for the user.
  • The compensator is a feature that ensures consistent engine power by maintaining the fuel/air ratio in the combustion mixture. This feature prevents the fuel-air mixture from getting richer as the air filter becomes clogged, and the filter doesn’t need to be cleaned until an appreciable drop in power occurs.
  • STIHL ERGOSTART features advanced combustion technology that uses four overflow channels to swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. This results in lower fuel consumption and high torque across a broad RPM range.
  • The STIHL Ematic system is another feature that sets STIHL ERGOSTART apart from the competition. This system reduces the consumption of chain lubricant by up to 50%, depending on the type of wood and the cutting attachment used. With this system, virtually every drop of chain lubricant is delivered to exactly the right spot, resulting in a cleaner and more efficient operation.
