tightened to Cup Support. For
proper sprayer operation lid must
seal tightly with the cup.
Avoid flexing or pushing on the
Cup Support when you evacuate
the air out of the FlexLiner.
Avoid pulling down on the
FlexLiner when you evacuate the
air out of the FlexLiner.
Make certain there is no damage

gasket.
Make certain the FlexLiner lip
and Cup Lid gasket are free of
debris.
