With the treatment hose, the 100°C water is safely led to the unwanted weeds to be treated.
The hose may break due to wear and abrasion. A damaged hose must be replaced, as a broken hose can leak boiling water onto the user.
For replacement, you need a 2 x 22 mm wrench, a little strength and skill to open the hose connectors.
Recycle the broken hose as a mixed waste.
