    Standard features

    • Compact and ergonomic

      The integrated battery cells mean that the tool is optimally balanced. The HSA is easy to handle. Its streamlined design creates plenty of room for manoeuvre.

    • Soft handle

      Thanks to the two-hand control device and soft handle with lever lock function and lever, the user always has the cordless hedge trimmer safely under control.

    • Tip protector with hanging eye

      The tip protector protects the tip of the cutter bar against damage when working close to walls and the ground. The hedge trimmer tip protector is fitted with an integrated hanging eye for wall mounting.

    • Charge level indicator

      The remaining working or charging time can be viewed at any time by pressing the button. Four LEDs light up, or flash green or red, to indicate the charging state or problems.

    • Activation key

      The tool can only be used with the activation key. If the key is removed, the tool switches off to guard against unintentional activation. The tool can be safely stored and transported.

    • Charger cable

      The STIHL HSA 45 draws its power from an integrated 18V lithium-ion battery. The battery is easily charged using the charger cable.

    • Quiet technology

      The STIHL cordless tools are so quiet you don't even need to wear ear protection.

    • Pruning system

      The single-sided precision-ground and double-sided cutting blades produce a very clean cut when trimming hedges. The 33° cutting angle delivers excellent cutting performance. The blade teeth geometry allows cutting of twigs up to 8 mm thick.

    • STIHL Smart Connector

      STIHL Connected is a cloud based system that enables professional users to digitally manage machine fleets and work assignments.

      This is managed by the STIHL Smart Connector - a sensor with a diameter of just under 5cm, which is mounted on the tool. It can be mounted on petrol, electric or battery-powered tools where it records and saves the operating hours while the motor is running and transmits this information via Bluetooth® 4.2 to the STIHL connected App (the smart connector can be mounted on non-STIHL tools too). The Smart Connector offers entirely new functions and services, as a basis for device management both in your home garden using the STIHL connected App, and for managing your machine fleet using the STIHL connected Portal. The STIHL connected Portal gives you a detailed overview of the status of your fleet of tools, as well as information such as duration of use on a particular work assignment.

      You can view power tool availability, analyse machine usage; plan and manage work tasks with associated resources; and analyse machine data, which you can then use to optimise your daily work processes. The Smart Connector also provides information about upcoming tool maintenance and, if needed, the system can arrange a workshop appointment directly with a STIHL Approved Dealer. Service-related tool data can also be shared with the dealer with your permission, so they can plan the servicing work in advance and order any necessary spare parts. This can shorten service times so the tool is quickly ready for use again.

      STIHL Connected is an intuitive way to manage your machine fleet and workload intelligently and efficiently. Visit: STIHL connected FAQs to find out more.
