Cleaning Procedure
WARNING: High pressure device --
Follow all safety warnings located on
sprayer and in the owner's manual.
Always clean using low pressure,
with the spray tip removed. Always
flush into a separate metal container
away from the sprayer. Never clean
the exterior of the pump while the
pump is plugged in or operating.
PRESSURE RELEASE
PROCEDURE:
Step 1: Engage trigger safety lock on
gun.
Step 2: Turn off pump and release fluid
pressure by turning the pressure relief
prime valve located on the side of pump
down.
LOW PRESSURE CLEANING
PROCEDURE:
Step 3: Remove tip and let soak clean,
in a small container of solvents or water.
Adjust fluid pressure to lowest possible
setting.
Step 4: Turn the pump on. Tilt syphon
tube above paint container, allowing the
sprayer to pump itself dry through the
return tube.
Step 5: Have available container of hot
soapy water if spraying latex (or suitable
solvent for oil base paints). Do not
clean with mineral spirits if using latex
paint as this will make jelly.
Step 6: Place syphon tube into
container with hot soapy water or
solvents. Let circulate for 2-3 minutes,
then turn unit off.
Step 7: To save paint still in spray hose,
turn prime valve up to spray position,
then carefully trigger gun into and
against side of metal paint container.
Be careful of splashing. When cleaning
solution appears, shut off gun and place
gun in a separate metal container.
Repeat process if spraying with two
guns.
Step 8: Trigger gun and let cleaning
solution circulate for approximately 2-3
minutes, then turn unit off.
Step 9: Turn prime valve down and
remove suction tube from cleaning
container. Turn unit on and allow
sprayer to pump dry.
Step 10: Take a clean container of
water or solvent and using low pressure
pump through system until clear. If
cleaning with water, pump a small
amount of mineral spirits or TITAN LS-
10 solution through pump. This will
protect against corrosion.
Step 11: Take suction tube out of
container and let sprayer run itself dry.
Step 12: Check filter on pump and gun.
Clean or replace.
Step 13: Remove spray tip from
solvent, clean with a soft bristle brush
and store in a dry place.
PROBABLE CAUSE
1. Inadequate fluid delivery

TROUBLESHOOTING AIRLESS GUN
Airless Tip Selection
Tips are selected by the orifice size and fan width. The proper
selection is determined by the fan width required for a specific job and
by the orifice size that will supply the desired amount of fluid and
accomplish proper atomization.
For light viscosity fluids, smaller orifice tips generally are desired. For
heavier viscosity materials, larger orifice tips are preferred. Please
refer to the chart below.
Note: Do not exceed the pump's recommended tip size.
The following chart indicates the most common sizes and the
appropriate materials to be sprayed.
.011 - .013 Lacquers & Stains 100 Mesh Filter
.015 - .019 Oil & Latex 50 Mesh Filter
.021 - .026 Heavy Bodied Latex & Blockfillers 5 Mesh Filter
Fan widths measuring 8" to 12" (20 to 30 centimeters) are most
preferred because they offer more control while spraying and are less
likely to plug.
