Clean cuts, clear conscience: Advanced engines, optimized tools, eco-friendly fuels

Handheld outdoor power equipment is used worldwide to shape and maintain the environment and are daily assistants in forestry, operated under very demanding environmental conditions. In the power tool sector, as elsewhere, the shift from petrol to battery-powered products is already well underway, especially for consumer applications. However, internal combustion engines will continue to be indispensable for professional users of power tools, who place the highest demands on their equipment in terms of performance and energy density. These power tools are often used in remote locations and thus far away from a possible charging infrastructure. To make a contribution to climate protection, biofuels and RFNBOs are necessary. The continuous optimization of engine technology and its overall system, including cutting tools (saw chain set, cutting wheel, etc.) is an important development goal of STIHL. The interaction between the saw chain, guide bar and power train are essential for optimal work progress. STIHL develops and manufactures all important components itself. The newly developed STIHL Hexa saw chain is a very innovative system with a new tooth shape and represents a milestone. Thanks to the Hexa sharpening pattern and the narrow kerf, the cutting performance of the previous standard saw chain is exceeded by up to ten percent. The difference is clearly visible to professional users when felling, limbing and cutting to length. The saw chain also remains sharp over a longer period of time and has a longer service life with optimal sawing performance. This means that the energy used is converted into work progress with a higher degree of efficiency. In combination with a highly efficient 2-stroke engine and with a sustainable fuel, in addition to the lower energy consumption per cutting surface, CO2 emissions can also be significantly reduced. This overall package makes a good contribution to climate protection during sequential timber harvesting.
