Operating Instructions
The Melnor Pulsating Sprinkler offers adjustable settings to customize your watering pattern and distance.
- Adjusting Spray Pattern (Arc):
- Locate the two slider clips on the sprinkler head.
- Move these clips to set the desired watering arc, from a narrow 30-degree wedge to a full 360-degree circle. The sprinkler will oscillate between these two points.
- Adjusting Spray Distance:
- On the top of the sprinkler head, locate the yellow dial labeled "DISTANCE".
- Turn this dial to adjust the spray distance, allowing for minimum or maximum reach.
- Water Flow: The sprinkler sprays a gentle rain of water. Adjust the water pressure from your hose spigot to control the overall flow rate.
- Side-Splash Control: The sprinkler features a special arm designed to eliminate wasteful side-splash, ensuring water is directed efficiently.
Maintenance
- Cleaning: Periodically check the sprinkler nozzle for any debris or mineral buildup that might obstruct the spray. Clean with a soft brush or a small pin if necessary.
- Winterization: Before freezing temperatures, disconnect the sprinkler from the hose and drain all water. Store the sprinkler in a dry, protected area to prevent damage from freezing.
- Storage: When not in use, store the sprinkler in a cool, dry place away from direct sunlight to prolong its lifespan.
