Safety Precautions

WARNING

Do not use equipment before reading this
section

Never operate this unit unless it is properly
grounded. A fire or explosion hazard is
present when spraying flammable materials.
Please read and understand the following
steps to assure safe operation of your
sprayer.

1. Always keep spray area well ventilated.

Always keep the turbine a minimum of 20
feet from spray activity.

Form No. 313-1079, REV B © 2000 Titan Tool Inc. All rights reserved. 1

2. Always follow the coating or solvent
manufacturer’s safety precautions and
warnings.

3. Never spray flammable materials near
open flames, pilot lights or any other
source of ignition.

4. Always wear spray masks and protective
eye wear while spraying.

5. Never alter or modify any part of this
equipment; doing so could cause it to
malfunction.

6. Never attempt to service or disassemble
the turbine while it is plugged in.

7. Never attempt to clean the exterior of the
turbine while plugged in. CAUTION: TO
REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT EXPOSE TO RAIN –
STORE INDOORS

8. Never point the spray gun at anyone or
any part of the body.

9. Never leave equipment unattended. Keep
away from children or anyone not familiar
with the operation of spray equipment.

10. Never remove lid of pressure pot without
relieving pressure first.

11. Never exceed 50 psi in pressure pot.

12. Do not use halogenated hydrocarbons in
Titan equipment.

Startup Procedures

Prepare the Paint

1. Prepare the material to be sprayed
according to paint manufacturers
recommendations.

2. Strain the paint before each use (cone
strainer P/N 770-119 provided).

3. Thin the material to be sprayed with the
recommended solvent. Most materials
need to be thinned to obtain spraying
consistency. To achieve the proper
viscosity for spraying, either a viscosity
cup can be used or trial and error.

4. If a viscosity cup is not available, thin the
materials to a point where you will achieve
a one second interval between drops after
a paint stick has been inserted and
removed from paint.

Gun and Turbine Set-Up

1. With the turbine switch in the off position,
plug into a grounded outlet at least 20 feet
from spray activity.

2. Attach air atomizing hose to turbine.

30

3. Attach the quart cup to the gun and attach
the tube from the gun to the cup. Attach
the air hose to the bottom of the gun.
Make sure that everything is secure before
spraying.

Spray Gun Adjustments

The “ProFinish” gun comes equipped with a
.051 fluid nozzle and needle and our “#0”
medium air cap. Always test your spray pattern
on a test surface before you begin to work.

1. Fan size adjustment is controlled by
turning the air cap retainer ring. Clockwise
will increase fan width, counterclockwise
will decrease fan width.

2. The top knob controls the air volume.
Clockwise will decrease air flow.

3. A round, horizontal or vertical fan pattern
can be achieved by rotating the air cap as
shown by the diagrams below.

4. A round pattern will require less material
flow than a wide pattern. Turning the lower
knob clockwise will decrease fluid flow;
counter-clockwise will increase fluid flow.

Fluid Nozzle / Needle / Air Cap
Selection

If after all of the appropriate adjustments are
made poor results are obtained, it may be
necessary to change to a different fluid nozzle /
needle or air cap. Refer to our selection chart to
match the appropriate components to the
material being sprayed.

NOTE: The smaller the nozzle size the

greater atomization.

1. To change fluid nozzle and tip remove air
cap (10) and retaining ring (11).

2. Squeeze trigger and with a wrench remove
fluid nozzle (7, use HVLP tool P/N 773­134, supplied).

3. Remove adjustment knob (18). Remove
needle spring (19) and needle (20).
Reassemble in reverse order 1 – 3.

NOTE: Never use lubricants containing

silicones. Silicones will adversely
affect spray finishes and is difficult
to remove once on equipment.

Application Techniques

The following techniques are recommended to
assure professional painting results. Hold the gun
perpendicular to the surface and always at an
equal distance of approximately 6”-8”.

Move the gun either across or up and down the
surface at a steady rate. Moving the gun at a
consistent speed provides even coverage. The
correct spraying speed allows for a full wet coat
of material without runs or sags. Do not angle the
gun as this will cause uneven paint build-up, runs
or sags. Begin movement of the gun before the
trigger is pulled.

RIGHT

Proper lapping (overlap of spray pattern) is
essential to an even finish. Overlap your strokes
about 50%.

WRONG

Problem Probable Cause

Orange Peel Material is too viscous Thin Material

Runs and Sags Too much solvent Add material

Blushing Fast drying thinner Add retarder
Pin Holing and
Solvent Pops Trapped solvents Reduce fluid flow and apply

Blistering Surface not primed properly Use appropriate primer

Coarse Finish Improper cleaning of surface Clean immediately before

Troubleshooting — Finish Problems

Cleaning Procedures

The Titan ProFinish system has been constructed
with the finest materials to assure trouble free
operation and durability. However, like any paint
tool, proper cleaning is essential for optimum
performance to be maintained. Always clean
thoroughly after each use.

1. Pour remaining material in the quart cup
back into the original container. For single
component materials ONLY. For catalyzed
material, consult coating manufacturer's
recommendation.

2. Pour a small amount of the appropriate
solvent for the type of material you are
spraying into the cup. Swirl the solvent
around in the cup and empty.

3. Thoroughly clean the interior of the cup and
wipe dry.

4. Pour a small amount of solvent into the cup
and spray through the gun to clean fluid
nozzle and needle.

5. After extended use, it might be necessary to
remove the fluid nozzle, needle, and air cap
to clean by hand, with a soft brush. (P/N
770-118, provided). Do not use a wire brush
or hard tools that could damage the
components. Also clean the inside of the
gun with solvent and a soft brush.
Reassemble gun and test with mineral
spirits.

6. Clean the exterior of the gun using solvent.
NEVER soak the gun in solvent. Some
solvents can damage the internal seals.

7. Check filter on turbine, clean or replace.
(Never use solvent to clean turbine filter,
blow clean with compressed air or replace.)

NOTE: If service is required on the turbine,

refer to the service center listing
enclosed or call 1-800-526-5362 for
assistance.

Please dispose of cleaning solvent and unused
coatings in an environmentally safe fashion.
Consult with material manufacturer on proper
procedure.
