amputation. See a physician immediately.
DO NOT TREAT AN INJECTION INJURY AS A SIMPLE
CUT! Injection can lead to amputation. See a physician
immediately.
PREVENTION:
• NEVER aim the gun at any part of the body.
• Do not aim the gun at, or spray any person or animal.
• NEVER allow any part of the body to touch the uid stream.
DO NOT allow body to touch a leak in the uid hose.
• NEVER put your hand in front of the gun. Gloves will not
provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut the pump off, and
release all pressure before servicing, cleaning the tip or
guard, changing tip, or leaving unattended. Pressure will
not be released by turning off the motor. The PRIME/
SPRAY valve or pressure bleed valve must be turned to
their appropriate positions to relieve system pressure.
Refer to the PRESSURE RELIEF PROCEDURE
described in this manual.
• ALWAYS keep the tip guard in place while spraying. The
tip guard provides some protection but is mainly a warning
device.
• ALWAYS remove the spray tip before ushing or cleaning
the system.
• Paint hose can develop leaks from wear, kinking and
abuse. A leak can inject material into the skin. Inspect
the hose before each use. Do not use hose to lift or pull
equipment.
• NEVER use a spray gun without a working trigger lock and
trigger guard in place.
• All accessories must be rated at or above the maximum
spraying pressure of the unit. This includes spray tips,
guns, extensions, and hose.
• Do not leave the unit energized or under pressure while
unattended. When the unit is not in use, turn off the unit and
relieve the pressure in accordance with the PRESSURE
RELIEF PROCEDURE described in this manual.
• Verify that all connections are secure before operating the
unit. Unsecured parts may eject at great force or leak a
high pressure uid stream causing severe injury.
• Always engage the trigger lock when not spraying. Verify
the trigger lock is functioning properly.
NOTE TO PHYSICIAN:
Injection into the skin is a traumatic injury. It is
important to treat the injury as soon as possible. DO
NOT delay treatment to research toxicity. Toxicity is a
concern with some coatings injected directly into the
blood stream. Consultation with a plastic surgeon or
reconstructive hand surgeon may be advisable.
HAZARD: HAZARDOUS VAPORS
Paints, solvents, insecticides, and other materials
can be harmful if inhaled or come in contact with the
body. Vapors can cause severe nausea, fainting, or
poisoning.
PREVENTION:
• Use a respirator or mask if vapors can be
inhaled. Read all instructions supplied

necessary protection.
• Wear protective eyewear.
• Wear protective clothing as required by coating manufacturer.
HAZARD: EXPLOSION OR FIRE
Solvent and paint fumes can explode or ignite.
Property damage and/or severe injury can occur.
PREVENTION:
• Provide extensive exhaust and fresh air
introduction to keep the air within the spray area free from
accumulation of ammable vapors. Solvent and paint
fumes can explode or ignite.
• Do not spray in a conned area.
• Avoid all ignition sources such as static electric sparks,
open ames, pilot lights, electrical appliances, and hot
objects. Connecting or disconnecting power cords or
working light switches can make sparks. Paint or solvent
owing through the equipment is able to result in static
electricity.
• Do not smoke in spray area.
• Fire extinguisher must be present and in good working
order.
• Place pump at least 25 feet (7.62 meters) from the
spray object in a well ventilated area (add more hose if
necessary). Flammable vapors are often heavier than air.
Floor area must be extremely well ventilated. The pump
contains arcing parts that emit sparks and can ignite vapors.
• The equipment and objects in and around the spray area
must be properly grounded to prevent static sparks.
• Keep area clean and free of paint or solvent containers,
rags and other ammable materials.
• Use only conductive or grounded high pressure uid hose.
Gun must be grounded through hose connections.
• For electric units — power cord must be connected to a
grounded circuit.
• Always ush unit into a separate metal container, at low
pump pressure, with spray tip removed. Hold gun rmly
against side of container to ground container and prevent
static sparks.
• Follow the material and solvent manufacturer’s warnings
and instructions. Know the contents of the paints and
solvents being sprayed. Read all Material Safety Data
Sheets (MSDS) and container labels provided with
the paints and solvents. Follow the paint and solvent
manufacturer’s safety instructions.
• Use extreme caution when using materials with a
ashpoint below 100ºF (38ºC). Flashpoint is the

Setup
The flow from the spray tip is at very high pressure.
Contact with any body part may be dangerous. Do
not place finger on gun outlet. Do not point the
gun at any person.
Read, understand, and follow all warnings before
starting or operating this sprayer.
Required tools: Crescent wrench and screwdriver
1. Compressor Requirements:
Consult the Technical Specications on each model for
the approximate air requirements.
NOTE: The requirements will vary on each model.
Proper grounding in important. This applies to
gas, electric and air powered models. The passage
of some materials through the nylon hose will build
up a static electric charge, which if discharged,
could ignite solvent vapors present and create an
explosion.
2. Grounding the pump:
Be sure the Admiral™ system is grounded. All Titan units
are equipped with a grounding lug. A Grounding Clamp,
Part No. 101-208 and Ground Wire, Part No. 101-212
should be used to connect the unit to a true earth ground.
These accessories can be ordered from your local
distributor.
a. Loosen the Grounding Screw.
b. Insert one end of the Grounding Wire into the slot in the
Grounding Lug. Tighten the screw.
c. Connect the other end of the Grounding Wire to a true
earth ground. Check local electrical regulations for
detailed grounding instructions.
5. Connecting the paint hoses:
The siphon hose and the bleed line hose have factory
installed PTFE tape on the male end of the hoses.
Tigthen the siphon hose and bleed line wrench tight.
6. One Gun Operation:
Attach the gun and hose. Always use a spray hose at
least 50 feet long. Do not use PTFE or thread sealant on
this assembly. Do not install the spray tip.
7. Multiple Gun Operation:
For models equipped with a second gun outlet, remove
the plug from the outlet and connect a second hose and
gun to the outlet.
Multigun manifolds with shut-off valves can be used when
more than two guns are needed. Never use this second
gun outlet for a one-gun operation.
For guns without a second gun outlet, connect a multi-
gun manifold at the single gun outlet. These manifolds
are either 2, 3, or 4 gun manifolds with shut-off valves.
Connect a hose and gun to each outlet.
3. Ventilation:
Areas must be well ventilated to prevent hazardous
operation with volatile solvents or exhaust fumes.
4. Connecting compressor to the sprayer:
Tighten the air hose wrench tight. The air hose has
factory installed PTFE ape on the male end of the hose.
See gure below.
8. Fill the Wet-Cup 1/2 full with Titan’s Lubrisolv, supplied
by the factory. This extends packing life.
9. Strain all paints with Titan’s 5 gallon Nylon strainer, Part
No. 160-500 or 1 gallon Nylon strainer, Part No. 160100 to assure trouble-free operation and freedom from
frequent cleaning of inlet screen and gun strainer.

Startup
1. Close the self relieving shutoff valve. The gure below
shows the handle in the closed position.
9. The Automatic Lubricator was set at the factory for the
correct injection rate. Do not adjust the lubricator until it is
necessary to rell the reservoir. The lubricator is lled with
AirCare™ lubricant. See gure below.
2. Start the compressor.
3. Drain the Petcock by pushing it off center.
4. Adjusting the air regulator:
The air motor is designed for a maximum air input of 120
psi. Turn the T-Handle clockwise to increase pressure
and counter-clockwise to decrease pressure. Verify the
amount of air pressure by reading the air gauge.
Paint pressure is directly proportional to the amount of air
pressure.
Example: Admiral 30:1
100 psi reading at air gauge = 3000 psi at pump outlet.
Consult the materials manufacturer for guidelines in establishing
the correct air pressure.
10. After relling the reservoir, the automatic lubricator will
need adjusting. Turn the adjusting screw clockwise
to increase the AirCare™ injection rate and counterclockwise to decrease it.
Check the injection rate by observing the ow through the
sight dome. The proper ow rate is 1 drop of AirCare™
per minute or every 90-125 cycles. In cold weather when
icing may occur, increase to one drop every 50-60 cycles.
Operation at very high cycle rates (i.e. greater than 60) will
require a higher AirCare™ injection rate.
IMPORTANT: Use only Titan AirCare™ Part No. 311-011
lubricant. Use of any detergent-type lubricants will cause a
serious problem with the pump and void the warranty.
11. Close the pressure bleed valve. The system is now under
pressure.
NOTE: Using a higher pressure than required will only
Once the correct air pressure has been established, lock the air
regulator by tightening the lock nut.

Operation
1. Repeat above Startup procedure with paint material. Lock
gun trigger and attach spray tip. See the Technical Data
Sheet on the gun provided for installation and selection of
the proper tip size.
2. Test spray pattern. Operate the pump at the lowest air
gauge reading which provides good atomization.
See the Troubleshooting guide if you are not getting the
proper pattern.
3. When restarting the unit, reduce the pressure at the air
regulator and open the pressure bleed valve.
Pressure Relief Procedure
Always reduce fluid pressure when you are
cleaning a clogged tip, changing a tip, servicing
any part of the system, or shutting down. Follow
the steps below.
1. Engage the gun trigger lock.
2. Close the self-relieving vented shutoff valve.
3. Open the pressure bleed valve by turning it counterclockwise three full turns.
4. Disengage the gun trigger lock and hold trigger open until
owof material stops.
Cleaning a Clogged Tip
The flow from the spray tip is at very high pressure.
Contact with any body part may be dangerous. Do
not place finger on gun outlet. Do not point the
gun at any person. Never operate the spray gun
without the proper tip guard.
1. Follow the Pressure Relief Procedure outlined above.
2. Lock the gun trigger.
3. Unscrew the nozzle cap and remove the spray tip. Wash
the tip in solvent and use a tip probe to remove any
clogged material.
4. If the gun is equipped with a Titan TAC 5™ Assembly, see

5. Release the gun trigger lock and spray briey into a waste
container to ush out any clogged particles.
6. Reset the trigger lock in the “Trigger Locked” position.
Release the trigger lock and resume spraying.
Color Change / Clean Out
IMPORTANT: Use only compatible solvents when cleaning
out oil based enamels, lacquers, coal tar, and epoxies.
Check with the fluid manufacturer for a recommended
solvent.
1. Reduce pressure by following the Pressure Relief
Procedure.
The pressure bleed valve should be turned counter-
clockwise three full turns.
2. Pull the siphon tube out of the material container.
3. Remove the spray tip from the gun. Hold the gun trigger
open until material ow stops.
4. Put siphon tube into wash solvent or water as applicable,
and operate pump slowly at low pressure until solvent
ows freely from pressure bleed valve line.
5. Close pressure bleed valve and hold gun trigger open
until solvent ows freely from gun. If solvent is not too
dirty, recirculate it by owing gun stream back into solvent
container. Use additional clean solvent and repeat
procedure if necessary.
6. If your model is equipped with a gun strainer screen and
pump outlet lter, check them daily. Use 50 mesh screens
with spray tip size .018 and larger. Use 100 or 200 mesh
screens with spray tip sizes .015 and smaller. Always
check the materials manufacturer’s recommendations for
proper ltration requirements.
7. On models with a outlet paint lter, replace paint lter cap
by turning clockwise. The lter cover should be hand
removable after the rst or second use with a new PTFE
O-ring.
IMPORTANT: O-ring must have PTFE backup washer to seal
properly.
8. If unit has been spraying a water soluble material, ush
with water and then repeat procedure with mineral spirits
or similar solvent.
9. Wash spray tip and preorice in solvent. Blow tip clean
with air pressure directed through the tip in the reverse
direction. Store preorice and tips in clean place.

Air Motor Maintenance
Air motors require a normal maintenance and service inspection
at 1500 hours service. Service procedure includes replacement
of motor service kit, minor. It is suggested that one motor
service kit, major (which includes the minor kit) be kept on hand
for normal maintenance and emergency repairs. Check the
individual model’s specications for correct part numbers.
Air motors should be served with moisure free air and for this, an
airline lter / moisture separator, such as Titan Part No. 141-057
is recommended. Very cold and humid air conditions combined
with high speed and high operating pressure may require a
moisture separator and an automatic lubricator to avoid icing.
NOTE: Anairlinelter/moistureseparatorarestandard
on many models.
Best lubrication will be obtained with an automatic lubricator such
as Titan Part No. 151-055.
Fluid Pump Maintenance
If the uid pump is going to be out of service for an extended
period of time, it is recommended that following cleanup, a
kerosene and oil mixture be introduced as a preservative.
Packings may tend to dry out from lack of use. The is particularly
true of the upper packing set for which upper packing lubricant,
Lubrisolv, Titan Part No. 310-200, is recommended in normal
usage. A sample of Lubrisolv accompanies each new unit. Do
not substitute water or paint solvent for Lubrisolv. Ordinary oil
may contaminate the paint material and is not recommended.
If the uid pump has been out of service for an extended period
of time, it may be necessary to prime the suction by pouring
some of the paint solvent into the inlet siphon tube to restart.
IMPORTANT: It is very important that the threads on the
inlet siphon hose coupling are properly sealed. Any air
leakage will produce erratic operation of pump and may
damage the system.
The up and down strokes should be approximately equal in
time. That is, one should not be faster than the other. A fast up
or down stroke may indicate air in the system or malfunctioning
valve seats. See Troubleshooting guide.
Hydraulic Motor and Paint Pump Service

stroke - air does not exhaust when
gun is open.
B. Motor stops, blows air from exhaust
when gun is open.
Piston rod is loose where it connects to the
uid section.
Trip springs or valve spring broken.
Motor is frozen due to icing or lack of
lubrication.
See above.
Air valve is in dead stall position.
O-rings were worn or damaged.
Tighten connection.
Inspect and replace where neessary.
Add 30 weight nondetergent oil to manual
oiler. If condition persists, install moisture
separator and automatic lubricator.
See above.
Remove one trip spring retainer, trip spring
and ball. Push spool valve up or down,
lubricate, reassemble and restart.
Install minor service kit and follow

Condition Possible Cause Correction
A. Pump delivers on upstroke only
or goes up slowly and down fast
(commonly called downstroke dive).
B. Pump delivers on down stroke only
or goes up fast and down slowly.
C. Pump moves up and down fast, not
delivering material.
D. Pump moves up and down slowly
when spray gun is shut off.
E. Not enough uid pressure at gun. Spray tip is worn.
F. Pump chatters on up or down stroke Solvent has caused upper packing to
Lower foot valve ball is not seating due to
trash or wear.
Material to viscous to siphon.
Air leaking in on siphon side or damaged
siphon hose. Siphon may be too small for
heavy material.
Upper packing nut (if applicable) is loose
or upper packings are worn.
Upper ball is not seating due to trash or
wear.
Lower packing set is worn.
Material container is empty or material is
too thick to ow through the siphon hose.
Bottom ball stuck to foot valve seat.
Siphon hose is kinked or loose.
Loose connections. Bleed valve is open
partially or bleed valve is worn. Lower
packing set is worn.
Upper and/or lower ball not seating.
Compressor (air operated units only) too
small. Outlet lter or gun lter is clogged.
Low voltage and/or inadequate amperage.
Hose size or length is too small or too
long.
swell, or packing is too tight.
Remove foot valve assembly. Clean and
inspect. Test foot valve by lling with
water. If ball fails to seal the seat, replace
ball.
Thin material - contact manufacturer for
proper thinning procedures.
Tighten all connections between pump
and paint container. If damaged, replace.
Switch to bigger siphon set.
If tightening upper packing nut does not
correct, change upper packings.
Check upper seat and ball with water. If
ball fails to seal seat, replace.
Replace packing set is worn.
Rell with new material. If too thick,
remove siphon hose and immerse pump or
add thinner to material. Change to bigger
siphon set. Open bleed valve to remove air
and restart pump.
Remove foot valve. Clean ball and seat.
Straighten.
Check all connections between pump and
gun. Tighten as necessary. If material is
owing from bleed hose, close bleed valve
or replace if necessary. Should none of
above be evident, replace lower packing.
Reset balls by cleaning.
Replace.
Clean or replace lter. Recommend proper
hose size and/or air compressor size.
Check electrical service. Correct as required.
Increase hose size to minimize pressure
drop through hose and/or reduce hose
lengths.
Back off upper packing nut 1/4 turn (if
applicable) and restart pump. Repeat if
necessary.
