Quiet technology

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

Compact and ergonomic

The integrated battery cells mean that the tool is optimally balanced. The HSA 45 is easy-to-handle. Its streamlined design creates plenty of room to manoeuver.

Soft handle

The HSA 45 can only be operated with two hands, so you are always in control. The soft-grip front handle can be operated from all sides so that you can work at exactly the right angle for your hedges.

Tip protector with hanging eye

The tip protector protects the tip of the blades from damage. It also features a hanging eyelet for easy storage in the garage or shed.

Pruning system

The blades on the HSA 45 are precision ground, so you get a precise cut on your hedges.

Activation key

The tool can only be used with the activation key. If the key is removed, the tool switches off to prevent it from being started accidentally. The HSA 45 can then be safely stored and transported.

Charge level indicator

There are four LEDs on the side of the trimmer to show you how much charge you have left. Just press the button next to the LEDs and you will be able to quickly see the charge level.

Charger cable

The built-in battery in the HSA 45 is easily charged using the charger cable.

A: You can cut branches up to 0.3"/8 mm in diameter.

Question: Does the hedge trimmer come with a blade cover?

A: Yes, your hedge trimmer comes with a scabbard to cover the blades during transport or storage. On new machines, the scabbard will be quite tight so you may need to use some force to remove it for the first few times. Just hold the scabbard about half way down and pull it away from you so your hands or body cannot come into contact with the blades.

#1 Using the HSA 45

You will get a straighter cut on your hedges, if you move the hedge trimmer in an upwards motion when trimming. The HSA 45 has a handy tip protector at the end of the blades - this means you can trim closer to the ground without damaging the blades.

#2 Cleaning your HSA 45

When you have finished using the HSA 45, remove the activation key. We suggest spraying a little resin solvent onto the blades to remove sap or resin, protect them from corrosion and stop them getting stuck together.

#3 Storing your HSA 45

We recommend that you store your HSA 45 hedge trimmer with around 40-60% charge (2 green LEDs), ideally within a temperature range of 0 to 50 degrees centigrade. Store it in a clean and dry area and keep out of the reach of children at all times.
