4. Operating Instructions
The GARDENA Water Stop Adapter features a simple lever mechanism for controlling water flow.
4.1 Regulating Water Flow
- The orange lever on the side of the adapter controls the water flow.
- To allow water to flow, turn the orange lever to align with the direction of the hose (open position).
- To stop the water flow, turn the orange lever perpendicular to the hose (closed position). This will completely shut off the water, allowing you to change accessories without getting wet or wasting water.
