The 6-day spoke wheel is for watering by day interval.
Watering by day interval: Using the 6-spoke wheel, put skip-a-day pins in the spokes for the days you do not want to water.
Example: To water every other day, put a pin in every other spoke.
After inserting the pins, turn the skip-a-day wheel clockwise until the spoke representing today sits on the grey colored day set button. A pin covering the day set button will prevent watering. lf the tripper gear has moved past the skip-a-day wheel put the spoke for tomorrow’s watering on the day set button.
