Toro INF55-6 Manuel D’Utilisation

Flushing the Sprinkler

1. With sprinkler operating, carefully step down on center of cap several times. Water will flow around riser and flush out debris.
2. Cycle sprinkler on and off several times to check for proper retraction. Cap should be even with top of body flange when fully retracted. If

riser sticks in up position, check for debris lodged between riser and body. Flush out all debris. Remove riser assembly if necessary.
