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 Relief Procedure
1. Engage trigger safety lock on gun.
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
1. Remove tip and let soak clean, in a
small container of solvents or water.
Adjust fluid pressure to lowest
possible setting.
2. Turn the pump on. Tilt syphon tube
above paint container, allowing the
sprayer to pump itself dry through the
return tube.
3. Have available a 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.
4. Place syphon tube into container with
hot soapy water or solvents. Let
circulate for 2-3 minutes, then turn
unit off.
5. 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.
6. Trigger gun and let cleaning solution
circulate for approximately 2-3
minutes, then turn unit off.
7. Turn prime valve down and remove
suction tube from cleaning container.
Turn unit on and allow sprayer to
pump dry.
8. 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.
9. Take suction tube out of container
and let sprayer run itself dry.
10. Check filter on pump and gun. Clean
or replace.
11. Remove spray tip from solvent, clean
with a soft bristle brush and store in a
dry place.
Cause
1. Inadequate fluid delivery
2. Fluid not atomizing
3. Insufficient velocity
4. Material too cohesive
5. Tip worn past pump capacity
1. Worn tip
2. Tip may be chipped
1. Plugged, worn or chipped tip
1. Leak in suction tube
2. Not enough hose
3. Tip too large or worn

3. Broken needle in gun
Problem
Spitting gun
Gun will not shut off
Gun does not spray
Troubleshooting Airless Gun
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

.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.
