1.3 Gasoline Engine Safety
1. Gas engines are designed to give safe and dependable service
if operated according to instructions. Read and understand
UIFFOHJOFNBOVGBDUVSFST0XOFST.BOVBMCFGPSFPQFSBUJOHthe engine. Failure to do so could result in personal injury or
equipment damage.
2. To prevent re hazards and to provide adequate ventilation,
keep the engine at least 1 meter (3 feet) away from buildings
and other equipment during operation. Do not place
ammable objects close to the engine.
3. People who are not operating the device must stay away from
the area of operation due to a possibility of burns from hot
engine components or injury from any equipment the engine
may be used to operate.

5. Gasoline is extremely ammable and is explosive under
certain conditions.
6. Refuel in a well-ventilated area with the engine stopped. Do
not smoke or allow ames or sparks in the refueling area or
where gasoline is stored.
7. Do not overll the fuel tank. After refueling, make sure the
tank cap is closed properly and securely.
8. Be careful not to spill fuel when refueling. Fuel vapor or
spilled fuel may ignite. If any fuel is spilled, make sure the area
is dry before starting the engine.

10. The muer becomes very hot during operation and remains
hot for a while after stopping the engine. Be careful not to
touch the muer while it is hot. To avoid severe burns or re
hazards, let the engine cool before transporting it or storing it
indoors.

gasoline. If spark knock or pinging persists, consult
an authorized dealer of the engine manufacturer.
Failure to do so is considered misuse, and damage
caused by misuse is not covered by the engine
manufacturer’s limited warranty.
Occasionally you may experience light spark knock
while operating under heavy loads. This is no
cause for concern, it simply means your engine is
operating eciently.

Gasolines Containing Alcohol
If you decide to use a gasoline containing alcohol (gasohol), be
sure its octane rating is at least as high as that recommended by
the engine manufacturer. There are two types of “gasohol”: one
containing ethanol, and the other containing methanol. Do not use
gasohol that contains more than 10% ethanol. Do not use gasoline
containing methanol (methyl or wood alcohol) that does not also

solvents and corrosion inhibitors.
iFuel system damage or engine performance
problems resulting from the use of fuels that contain
alcohol is not covered under the warranty. The
engine manufacturer cannot endorse the use of
fuels containing methanol since evidence of their
suitability is incomplete at this time.
Before buying gasoline from an unfamiliar station, try
to nd out if the gasoline contains alcohol. If it does,
conrm the type and percentage of alcohol used. If
you notice any undesirable operating characteristics
while using a gasoline that contains alcohol, or one
that you think contains alcohol, switch to a gasoline
that you know does not contain alcohol.

3. Description of unit
3.1 Airless process
The main area of application are thick layers of highly viscous coating
material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it
to the tip. Pressed through the tip at a pressure of up to a maximum
of 248 bar (24.8 MPa), the coating material is atomised. This high
pressure has the eect of micro ne atomisation of the coating
material.

The gasoline engine or electric motor (g. 1, item 1) drives the
hydraulic pump (3) by means of a V-belt which is under the belt cover
(2). Hydraulic oil ows to the hydraulic motor (4) and then moves the
piston up and down in the material feed pump (5).
The inlet valve is opened automatically by the upwards movement
of the piston. The outlet valve is opened when the piston moves
downward.
The coating material ows under high pressure through the high-
pressure hose to the spray gun. When the coating material exits from
the tip it atomises.
The pressure control valve (6) controls the volume and the operating
pressure of the coating material.

Operation
4. Operation
This equipment produces a fluid stream at extremely
high pressure. Read and understand the warnings
in the Safety Precautions section at the front of this
manual before operating this equipment.
4.1 Setup
1. Make sure the siphon hose (g. 4, 1) is connected to the uid
section (2) and the bleed hose (3) is connected to the bleed
valve (4). They each have factory installed Teon tape on the
male end of the hoses and should be wrench tight.
3
1
4
2
2. Attach a minimum of 15m of nylon airless spray hose to the
sprayer. Do not use Teon tape or thread sealant on the spray
hose connection.
3. Attach an airless spray gun to the spray hose. Do not attach
the tip to the spray gun yet. Remove the tip if it is already
attached.
a. To use two guns, remove the plug from the second gun outlet
on the lter assembly. Connect a hose and gun to the outlet.
iFor multiple gun operation, connect a multiple gun
manifold to the single gun outlet. Connect a hose
and gun to each outlet. Make sure the second gun
outlet remains plugged. See “Technical Data”,
Section 3.5 to determine number of guns and
maximum spray tip sizes.

Attention
Piston Lube prevents increased wear and tear to the
packings.
5. Check the hydraulic uid level daily before starting the
sprayer. The hydraulic uid level should be at the “Full” mark
on the dipstick. Refer to the Maintenance section of this
manual for hydraulic system maintenance instructions.
Attention
Use of Titan’s Coolflo™ Hydraulic Fluid (P/N 430-361)
is mandatory in the hydraulic system. Do not use
any other hydraulic fluid. Use of any other hydraulic
fluid may seriously damage the hydraulic system
and will void the warranty.
6. For gas models, check the engine oil level daily before starting
the sprayer. The gasoline engine oil level is determined by
UIFFOHJOFNBOVGBDUVSFS3FGFSUPUIFFOHJOFNBOVGBDUVSFSTservice manual supplied with this sprayer.
7. For electric models, use a 20 amp service outlet. Always
locate the electric model within 10 to 15 feet of the service

cord is necessary, use only a grounded 3-wire #12 extension
cord.
8. Make sure the sprayer is earthed. All sprayers are equipped
with a earthing lug. An earthing cable (not supplied) should
be used to connect the sprayer to a true earth ground.
Check your local electrical regulations for detailed earthing
instructions.
Proper earthing is important. This applies to both
gas and electric powered models. The passage of
some materials through the nylon uid hose will
build up a static electric charge, which if discharged,
could ignite solvent vapors present and create an
explosion.
9. Strain all paints with a nylon strainer to ensure trouble free
operation and freedom from frequent cleaning of the inlet
screen and gun lter.
10. Make sure the spray area is well ventilated to prevent
hazardous operation with volatile solvents or exhaust fumes.
If lacquer or other flammable materials are to be
sprayed, ALWAYS locate the sprayer outside the
immediate spraying area. Failure to do so may cause
an explosion.

6.2 Maintaining the Filter Assembly
Clean the lter regularly. Dirty or clogged lters can greatly reduce
ltering ability and cause a number of system problems including
poor spray patterns, clogged spray tips, etc.
Cleaning (Fig. 15)
To clean the lter, perform the following procedure.
1. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual.
2. Remove the lter cap assembly (1) and spring (2).
3. Pull the lter element with ball straight (3) out of the lter
body (4).
4. Clean inside the lter body, lter element with ball, and lter
cap assembly using the appropriate solvent.
iUse care in handling parts as dirt, debris, scratches,
or nicks may prevent o-rings or gaskets from sealing.
This lter element lters from the inside out. Be sure
to clean the lter element thoroughly on the inside.

Inspection (Fig. 15)
Inspect all parts of the lter assembly before reassembly.
1. Inspect the ball inside the lter element. If the ball has
pressure cuts or scratches, replace the lter element.
a. If the ball is cut, remove the Teon o-ring (5) using an o-ring
pick and remove the carbide seat (6).
b. Check the seat for nicks or grooves. If the seat is damaged,
replace.
iRemoval of the Teon o-ring will damage the o-ring
and require replacement.
2. Remove the spring (2) from the spring guide on the lter cap.
a. Measure the length of the spring uncompressed. If it measures
less than 3/4” from end to end, replace.
b. Push the spring back onto the spring guide until it “snaps” back
into position.
3. Inspect the two Teon gaskets (7,8) and the Teon o-ring (5)
for deformity, nicks, or cuts. Replace, if needed.
iThe Teon gaskets, Teon o-ring, and spring are
packaged in Filter Service Kit P/N 930-050.
Reassembly (Fig. 15)
After cleaning and inspecting all parts, reassemble the lter.
1. Place the carbide seat (6) into the lter body (4). Make sure
the beveled side of the seat is facing up.
2. Place the Teon o-ring (5) into the groove on the outer
diameter of the carbide seat (6).

6.3 Maintaining the Hydraulic System
Attention
Use of Titan’s Coolflo™ Hydraulic Fluid is mandatory
in the PowrTwin Plus hydraulic system. Do not use
any other hydraulic fluid. Use of any other hydraulic
fluid may seriously damage the hydraulic system
and will void the warranty.
1. Check the hydraulic uid daily. It should be at the “Full”
mark (g. 16, item 1) on the dipstick (2). If it is low, add only
5JUBO$PPMóP)ZESBVMJD'MVJE1//FWFSBEEor change hydraulic uid except in a clean, dust-free area.
Contamination of the hydraulic uid will shorten hydraulic
pump life and may void warranty.
1

2. Change the hydraulic uid every twelve months. Drain the
old uid from the tank and ll with 6.25 quarts of hydraulic
uid. Start the sprayer at just enough pressure to operate the
uid section. Run the sprayer at this low pressure for at least
5 minutes. This removes air from the system. Check the uid
level after this procedure. Do not over-ll.
iWhen replacing the hydraulic filter (3) during a
fluid change, it may be necessary to add up to one
additional quart of hydraulic fluid.
3. The hydraulic system has an external, replaceable hydraulic
lter. Change the lter every twelve months.
4. The hydraulic pump should not be serviced in the eld. If
service on the hydraulic pump is required, it must be returned
to Titan.
6.4 Maintaining the Fluid Section
If the sprayer 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. This is particularly true of the upper packing
TFUGPSXIJDIVQQFSQBDLJOHMVCSJDBOU1JTUPO-VCF1/JTrecommended in normal usage.
If the sprayer has been out of service for an extended period of time,
it may be necessary to prime the pump with solvent. It is extremely
important that the threads on the siphon hose coupling are properly
sealed. Any air leakage will produce erratic operation of the sprayer
and may damage the system. The up and the down strokes should
be approximately equal in time (one should not be faster than the
other). A fast up or down stroke may indicate air in the system or
malfunctioning valve or seats (see the Troubleshooting section).
