Q: How long does the battery last?
A: The recommend AK 10 Battery will last up to 55 minutes, this does depend on what is being cut and how the tool is being used.
Q: How long does it take to charge?
A: To fully charge an AK 10 Battery it takes 95 minutes, or to charge it up to 80%, it takes 70 minutes with the AL 101 charger.
Q: Are the Batteries Interchangeable?
A: Yes, all of the tools in the STIHL AK Battery System are interchangeable. There are three different batteries in the range, which all have different capacities. For the HSA 50, we recommend the smaller capacity AK 10 battery as it is lighter and means the tool is perfectly balanced, but you can also use the AK 20 and AK 30 battery in this tool.
Q: Will the blades need sharpening?
A: Keeping the blades sharp will give a neat cut on whatever you are trimming. If you notice that the blades are getting jammed easily or the machine is struggling, the blades may need sharpening. Our STIHL SHOP retailers can do this for you or it is easy to do yourself.
Q: What should I wear when using this tool?
A: We recommend that you wear snug-fitting clothes, eye protection, gloves and sturdy boots or shoes, and tie back long hair.
Q: Does this tool come with a Warranty?
A: Yes, the HSA 50 tool, battery and charger all come with a STIHL domestic 5 year warranty.
Q: Does this hedge trimmer come with a battery and charger?
A: This is the tool-only version and does not include a battery or charger. We recommend pairing it with the STIHL AK 10 battery and AL 101 charger for the best balance of weight and runtime. Or purchase the kit version which contains everything you need.
Q: What size branches can the HSA 50 cut?
A: The HSA 50 is designed for trimming hedges, shrubs, and new growth. It can comfortably cut green hedge material and small branches, making it ideal for maintaining residential gardens and lifestyle properties. It is not suitable for cutting thick or woody material.
Q: Is the HSA 50 suitable for beginners?
A: Yes. The lightweight design, quiet battery operation, and simple controls make the HSA 50 easy to use for homeowners who want professional-quality results without the noise and maintenance of a petrol hedge trimmer.
Q: How heavy is the HSA 50?
A: The HSA 50 weighs just 2.9 kg (without battery), making it comfortable to use for extended periods and easier to manoeuvre when shaping hedges and shrubs.
Q: Can I use this hedge trimmer in wet conditions?
A: No. For safety reasons, always avoid using this hedge trimmer in rain or wet conditions and follow the operating instructions provided in the owner's manual.
Q: Why should I choose a battery hedge trimmer over a petrol model?
A: Battery hedge trimmers are quieter, lighter, easier to start, and require less maintenance than petrol-powered alternatives. They also produce no direct emissions during operation.
