Before You Water
Operation
Connect the sprinkler to the hose
Attach the garden hose securely to the hose-end of the sprinkler.
Place the sprinkler on the lawn
Set the metal base on a stable, level area with the spray nozzles facing the watering area.
Adjust the watering range
Move the sliding tabs to select the desired position and customize the watering pattern.
Turn on the water
Open the faucet and confirm the sprinkler oscillates and sprays across the selected range.
Watch for runoff
Monitor the watering area and stop or adjust the sprinkler if water begins running off the lawn.

Watering Tips
Water in the morning
Morning watering helps minimize water loss through evaporation.
Water deeply but less often
Deep, less frequent watering helps promote deeper root growth.
Avoid runoff
Watch water application and adjust placement or timing if water begins running off the lawn.
Maintenance + Care
Follow these steps if the sprinkler stops working properly or shows poor water flow due to debris or dirt buildup.
Remove and rinse the inlet filter
Remove the inlet filter from the hose-end of the oscillator and rinse it under water.
Remove the cleaning pin
Take the cleaning pin from the opposite end of the oscillator.
Flush the sprinkler
Connect the oscillator to a spigot. Turn on the faucet and, while water continues running, gently spin the oscillator tube back and forth for a few minutes.
Reinstall the inlet filter
Screw the inlet filter firmly back into place after flushing.
Clear nozzle clogs
Use the provided cleaning pin to clear clogs from the spray nozzles.
Return the cleaning pin
Fit the cleaning pin firmly back in place before using the sprinkler again.
Storage
Turn off the faucet
Shut off the water supply before disconnecting the sprinkler.
Disconnect the hose
Remove the garden hose from the hose-end connection.
Drain remaining water
Allow water to drain completely from the sprinkler before storing.
Store safely
Store the sprinkler in a clean, dry location when not in use, especially before freezing temperatures.
