Tracker Operation - Underhill Tracker Assembly Instructions And Operation Manual

Tracker Operation

When connected to a 1" diameter hose (to support the flow demand of the impact
sprinkler), with a minimum of 50 Psi, the Tracker will automatically pull itself along the
nylon cord, then automatically shut off once it's reach the ground stake.
Unthread the impact sprinkler and open the plastic cover of the Tracker. Figure 9-1
shows mechanical "On/Off" features of the Tracker.
When the cut-off rod is turned downward as shown in Figure 9-2, the spring-loaded rod
will be pushed away from the valve. A rubber ball will be pressed to the seal ring to
close the water flow to space outside of the diaphragm shown above, thereby allowing
water to flow past the turbine and out through the sprinkler.
