2. Safety Information
Please read and understand all safety warnings before operating this product. Failure to follow these instructions may result in injury or property damage.
- Keep away from children.
- Do not use during lightning storms.
- Avoid electrical hazards; ensure no electrical wiring is near the watering area.
- Always turn off the water supply before removing or adjusting the sprinkler.
- Store the sprinkler in a dry place when not in use to prevent damage and extend its lifespan.
3. Setup
- Connect to Water Source: Attach a standard garden hose to the inlet connection at the base of the sprinkler. Ensure the connection is tight to prevent leaks.
- Position the Sprinkler: Firmly insert the metal T-spike into the ground in the desired watering area. Ensure the spike is stable and the sprinkler head is upright.
- Connect Multiple Sprinklers (Optional): If watering a larger area, connect additional sprinklers in series using the flow-through design at the spike base. Attach a garden hose from the outlet of the first sprinkler to the inlet of the next.

4. Operating Instructions
Once the sprinkler is set up and connected to a water source, slowly turn on the water supply. The sprinkler head will begin to rotate and distribute water. Observe the spray pattern and coverage to ensure it meets your watering needs.
Adjusting Spray Pattern and Distance:
- Arc Adjustment: The sprinkler allows for adjustment from a partial circle (1 degree) to a full 360-degree circle. Locate the adjustment collars or tabs on the sprinkler head and move them to set the desired watering arc.
- Distance Control: A diffuser screw or tab is typically located on the sprinkler head. Turning this screw will break up the water stream, reducing the spray distance. Adjust as needed to prevent over-watering or spraying unintended areas.
- Stream Adjustment: The anti-backsplash arm helps maintain smooth rotation and consistent water distribution. Ensure it moves freely.
5. Maintenance
Regular maintenance helps ensure optimal performance and extends the life of your sprinkler.
- Cleaning Nozzle: Periodically check the sprinkler nozzle for any debris or mineral buildup that might obstruct the water flow. Clean with a small brush or needle if necessary.
- Winter Storage: Before freezing temperatures, disconnect the sprinkler from the hose, drain all water, and store it in a dry, protected area to prevent freeze damage.
- Inspect Connections: Regularly check hose connections for wear or leaks. Replace washers if needed to maintain a tight seal.
6. Troubleshooting
If you encounter issues with your sprinkler, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven spray pattern or reduced distance | Clogged nozzle, low water pressure, or incorrect adjustment. | Clean the nozzle. Check water supply pressure. Adjust the diffuser screw and arc settings. |
| Sprinkler not rotating | Insufficient water pressure, debris in the mechanism, or arm obstruction. | Ensure adequate water pressure. Inspect for and remove any debris. Check that the anti-backsplash arm moves freely. |
| Water leaking from connections | Loose hose connection or worn washer. | Tighten hose connections. Replace the rubber washer in the hose if it is worn or missing. |
