Top specs

  • Power Supply

    Gasoline

    Ideal for long and demanding work, they provide great autonomy as they do not depend on cables and sockets. Their disadvantages are increased noise and high maintenance and usage costs.

  • Displacement

    Displacement (measured in cubic centimeters - cc) is essentially the size and power of the engine of a petrol-powered chainsaw.

  • Bar Length

    The bar length is the maximum thickness of wood you can cut in a single pass. It is measured in centimeters (cm).


    - Longer bar = Cutting thicker logs. It allows you to handle larger trees.

    - Shorter bar = Better control and safety. It is more flexible, lighter, and ideal for pruning, as it reduces the risk of "kickback".


    The bar should always be proportional to the power of the engine. A small engine cannot effectively support a huge bar.
  • Weight 2.5 kg

  • Horsepower

    Horsepower (HP) is the actual, useful power produced by the chainsaw to turn the chain. While engine displacement shows the size of the engine, horsepower indicates its efficiency.


    More horsepower (HP) = Faster and more efficient cutting.

  • Carving Bar

    The carving bar, also known as the woodcarving bar, is a specialized accessory for chainsaws, designed not for quickly cutting large logs, but for precision cuts, detailed work, and artistic woodcarving.

  • Step

    The chain pitch is the distance between the links of the chain and indicates its size.

    Larger pitch → more "aggressive" and powerful cutting

    Smaller pitch → smoother cutting and better control

  • Guide Bar Thickness

    The guide bar thickness is the thickness of the chain’s tongue that fits into the guide bar. It must match perfectly with the groove of the guide bar.
