The light HSA 66 Battery Hedge Trimmer has an efficient EC-motor that provides great cutting performance and maintains a constant stroke rate even during tough jobs.
Double-sided blades cut smoothly and efficiently on both the upwards and downwards stroke. The blades are droplet shaped and diamond ground which helps to guide branches between the cutting teeth for a precise and even finish - even through thick and tough shrubbery. The 50cm blade is an efficient working length for most applications and a tip protector helps protect the blade tip from damage.
Featuring long run times with no gradual drop in the tools performance – the HSA 66 runs at full power until the battery is fully depleted.
The HSA 66 is part of our AP Cordless System - the battery can be used on a wide range of other tools from the AP range.
Run time with AP 200 battery: up to 144 min
Run time with AP 300 battery: up to 180 min
Run time with AP 300 S battery: up to 223 min
Run times quoted are based on ideal operating conditions. Times will vary depending on load and conditions.

STIHL Battery System
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: How long will the Battery last?
A: The recommended AP 100 Battery will last up to 72 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 AP 100 Battery it takes 100 minutes, or to charge it up to 80%, it takes 75 minutes with the AL 101 charger.
Q: Are the Batteries Interchangeable?
A: Yes, all of the tools in the PRO Cordless System use the same style of battery. There are 7 different batteries in the range, which all have different capacities. For the HSA 66, we recommend the smaller capacity AP 100 battery as it is lighter which means the tool is perfectly balanced, but you can use any of the other batteries in this range.
Q: Does the performance of the Battery reduce as it depletes?
A: No there is no gradual drop in performance – the battery runs at full power until it is fully depleted.
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.
Q: Does this tool come with a warranty?
A: Yes, the HSA 66 has a 2 year STIHL domestic warranty.
