Underhill Tracker Assembly and Operation Instructions
13
Operation
Now that the Tracker is fully assembled, connect a 1” hose to a water source and then other end
to the quick connect fitting of the Tracker.
Required Operating Pressure
The Tracker requires a
minimum of 50 Psi
at the inlet side of the machine. If delivery
pressure is measured to be the same or lower at the water source, this could impact the
product’s performance where it may not operate as expected.
Speed Adjustment
The Tracker has variable travel speed adjustment capability located under the cover
above the water supply inlet see Figure 13-1. Turn the speed control knob (-) or (+) to
increase or decrease the factory-default setting. One complete turn of the speed
control knob in either direction will produce a speed variation of approximately 4%.

Note: Remember that even though the Tracker will automatically shut off,
the water supply line remains pressurized. The water supply line or source
should be turned off once the irrigation cycle is complete.
Set-up to Water
Set the Tracker approximately 50 feet from the boundary of the area to be irrigated.
Pull the nylon pull-rope to the desired length and tie-off to the ground stake.
Connect a 1” supply hose to the Tracker inlet. Open the hose bib or quick coupler slowly
to begin irrigating and confirm the Tracker begins to travel.
If it fails to move forward, turn off the water and confirm the auto shut-off has been
reset properly.
