Safety Precautions
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.
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.
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.
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 773-
134, 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.
NOTE: The smaller the nozzle size the
greater atomization.
