Underhill Tracker Assembly and Operation Instructions

When the pull rope mechanism is pushed inward (see Figure 10-1), simulating the all of
the nylon pull rope has been spooled, the spring loaded cut-off rod slides into the notch
as shown in orange below.
Cut-Off Rod Push Inward
Figure 10-1
When cut-off rod is in this position, a rubber ball will be pushed away from the seal ring.
This enables water to by-pass the seal ring and pressurizes the space outside of the
diaphragm shown in blue in Figure 10-2 below automatically shutting off the Tracker.

Note: If the Tracker is observed to no longer pull it self along the nylon rope,
then the cone-shaped inlet of the diaphragm is clogged w/ debris and needs to
be cleaned.
