Install The Impact Sprinkler; Converting A Part Circle To A Full Circle Arc Pattern - Underhill Tracker Assembly Instructions And Operation Manual

Install the Impact Sprinkler

Wrap the male threads of the impact sprinkler with 3 or 4 turns of Teflon tape and
thread into the 1" outlet on top of the Tracker, see Figure 8-1. Tighten ¼ turn further
with a crescent wrench.

Note: Confirm the red cover is closed before connecting the sprinkler.

Converting a Part Circle to a Full Circle Arc Pattern

Unthread and remove the Tracker sprinkler. Turning the sprinkler upside
down, locate the arc pattern "trip-lever" on the opposing side of the main
nozzle as shown in Figure 8-2. There are two rectangular openings, one
larger than the other (shown in dashed yellow lines). Pinch the outward
facing wires together while rotating the one side with the larger slot molded
in the underside of the mechanism upward at the same time to remove the
trip lever. Now the sprinkler will rotate continuously in a full circle.
