NOTE: The air filter in the filter housing on
the side of the head must be checked and
cleaned periodically, more often if used
under very dusty conditions or when a
great deal of fog from spraying is allowed
to circulate near unit.
IMPORTANT: Unit should be located as
far from spraying area as hose will allow
to prevent over-spray from clogging filter.
