surface such as paper or cardboard which
interrupts grounding continuity.
Use only water-based or oil-based
(mineral spirit-type) materials with flash
point greater than 100° F (38° C). Do not
use materials which state “FLAMMABLE”
on the packaging. For more information
about your material, request a Safety Data
Sheet (SDS) from distributor or retailer.
Clean in a well-ventilated area. Keep a
good supply of fresh air moving through
the area.
To avoid serious injury or damage to
equipment, do not expose the sprayer
electronics to cleaning fluids. Keep
sprayer at least 10 in. (25 cm) above the
rim of the container when cleaning.
The equipment must be grounded to
reduce the risk of static sparking and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric
shock. A good ground provides an escape
wire for the electric current.

Sprayer Diagnostics
Problem Cause Solution
Sprayer makes sound
but no material is
sprayed when Trigger is
pulled
Spray Tip is clogged See Clear Tip Clogs, page 19.
Sprayer is not primed 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.
Pump Filter is plugged 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.
Prime Knob is in PRIME position Turn Prime Knob forward to
SPRAY position.
