Solution
See Clear Tip Clogs, page 19.
Repeat Start Up procedure to
ensure all air is evacuated from
the FlexLiner. See Startup, page
14.
Verify Cup Lid is tight. An under
tightened Cup Lid will allow air to
seep into the FlexLiner and
cause a loss of prime. Add Seal
Lube (included) to the Cup Lid
gasket to ensure an airtight seal.
If the sprayer sprays when
upside down by not upright,
there is likely still an air leak into
the cup. Try replacing the
FlexLiner and VacuValve (extra
of both included with sprayer).
Make certain there is only one
FlexLiner in the Cup Support.
Make certain there is no damage
to or debris on the top sealing
edge of the FlexLiner or Cup Lid
gasket.
Make certain all the air is out of
the FlexLiner and the VacuValve
cap is properly closed.
Make certain the cup assembly
is properly installed onto the
sprayer.
Clean sprayer. See Cleanup,
page 21.
Remove the Pump Filter from the
pump. Clean both sides of the
Pump Filter. While the Pump
Filter is removed, inspect and
ensure no dried paint debris is
collected inside the pump inlet.
Turn Prime Knob forward to
SPRAY position.
Turn Spray Tip to SPRAY
position.
Refill FlexLiner. See Cup Fill,
page 11.
