a) Fill the bearing chamber through the main body of the Watchdog until it reaches the
optimum fluid level visible in the bullseye sight.
b) Fill the watchdog reservoir using a funnel.
c) Verify o-ring is on the Watchdog oiler spout.
d) Place your thumb over the reservoir spout. Invert and insert the spout into the internal
threaded boss on the main body.
