Intelligent Design Features STIHL has equipped the ASA 20.0 with a range of smart features for enhanced control and usability. The blades can be set to two different opening widths, allowing for faster work on thinner twigs and branches.

All essential information, including battery charge level, selected blade opening, and the total number of cuts made, is clearly visible on the bright OLED display. Thanks to the efficient EC Motor, the tool delivers constant power regardless of the battery’s charge status, ensuring consistent performance from the first cut to the last.

This product is a complete kit. It includes the ASA 20.0 cordless secateurs, one STIHL AS 2 lithium-ion battery, and one STIHL AL 1 standard charger, providing everything you need to start working. How many cuts can I make on a single charge? With a fully charged AS 2 battery, the ASA 20.0 can make a maximum of 2,000 cuts. Please note that this number can vary depending on the thickness and type of wood being cut. What is ‘progressive cut’ on these secateurs? Progressive cut is a feature that gives you maximum control and precision. The movement of the cutting blade directly follows the movement of your finger on the trigger. The blade only closes as far as you press the lever and opens immediately when you release it. Can I adjust the blade opening? Yes, the ASA 20.0 features two adjustable blade opening widths. You can use the full width for thicker branches up to 25mm or select the smaller opening for thinner twigs, which increases cutting speed and efficiency. User Manuals / Downloads View STIHL Brochure
