If
you suspect that the spray tip or hose is
completely
clogged,
or that pressure has not been fully relieved
after following the steps above,
very slowly loosen
the tip guard retaining nut or hose end coupling and
relieve pressure gradually, then loosen completely.
Now
clear the tip or hose obstruction.
1. Open the bypass valve (66) ONE turn counter-
clockwise.
Do not place the pump intake in the
pail
yet.
