ca.gov.

HAZARD: INJECTION INJURY

A high pressure stream produced by this equipment

can pierce the skin and underlying tissues, leading to

serious injury and possible amputation.

Do not treat a spraying injury as a harmless cut. In

case of injury to the skin through coating materials

or solvents, consult a doctor immediately for quick

and expert treatment. Inform the doctor about the

coating material or solvent used.

PREVENTION:

• NEVER aim the gun at any part of the body.

• 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 uid pump o and

release all pressure before servicing, cleaning the tip guard,

changing tips, or leaving unattended. Pressure will not be

released by turning o the engine. The PRIME/SPRAY valve

or pressure bleed valve must be turned to their appropriate

positions to relieve system pressure.

• ALWAYS keep 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.

• 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

operating pressure range of the sprayer. This includes spray

tips, guns, extensions, and hose.

HAZARD

: HIGH PRESSURE HOSE

The paint hose can develop leaks from wear, kinking

and abuse. A leak can inject material into the skin.

Inspect the hose before each use.

PREVENTION:

• Avoid sharp bending or kinking of the high-pressure hose. The

smallest bending radius amounts to about 20 cm.

• Do not drive over the high-pressure hose. Protect against

sharp objects and edges.

• Replace any damaged high-pressure hose immediately.

• Never repair defective high-pressure hoses yourself!

• Electrostatic charging of spray guns and the high-pressure

hose is discharged through the high-pressure hose. For this

reason the electric resistance between the connections of the

high-pressure hose must be equal to or lower than 1M.

• For reasons of function, safety and durability use only original

Titan high-pressure hoses.

• Before each use, check all hoses for cuts, leaks, abrasion

or bulging of cover. Check for damage or movement of

couplings. Immediately replace the hose if any of these

conditions exist. Never repair a paint hose. Replace it with

another earthed high-pressure hose.

• Make sure power cord, air hose and spray hoses are routed in

such a manner to minimize slip, trip and fall hazard.

HAZARD: EXPLOSION OR FIRE

Flammable vapors, such as solvent and paint vapors,

in work area can ignite or explode.

PREVENTION:

• Use equipment only in well ventilated area. Keep a good

supply of fresh air moving through the area to keep the air

within the spray area free from accumulation of ammable

vapors. Keep pump assembly in well ventilated area. Do not

spray pump assembly.

• Electric models only - Do not use materials with a ashpoint

below 38º C (100º F). Flashpoint is the temperature at which a

uid can produce enough vapors to ignite.

• Gas models only - Do not ll fuel tank while engine is running

or hot; shut o engine and allow to cool. Fuel is ammable

and can ignite or explode if spilled on a hot surface.

• Eliminate all ignition sources, such as pilot lights, cigarettes,

portable electric lamps and plastic drop cloths (potential static

arc).

PowrTwin Plus 3

GB

Safety precautions

• Keep work area free of debris, including solvent, rags and

gasoline.

• Do not plug or unplug power cords, or turn power or light

switches on or o when ammable vapors are present.

• Ground equipment and conductive objects in work area.

Make sure the grounding cable (not equipped) is connected

from the grounding lug to a true earth ground.

• Use only grounded hoses.

• Hold spray gun rmly to the side of a grounded pail when

triggering into pail.

• If there is static sparking or if you feel a shock, stop operation

immediately.

• Know the contents of the paint 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.

• Do not use a paint or solvent containing halogenated

hydrocarbons. Such as chlorine, bleach, mildewcide,

methylene chloride and trichloroethane. They are not

compatible with aluminum. Contact the coating supplier

about compatibility of material with aluminum.

• Keep a re extinguisher in work area.

HAZARD: HAZARDOUS VAPORS

Paints, solvents, and other materials can be harmful

if inhaled or come in contact with body. Vapors can

cause severe nausea, fainting, or poisoning.

PREVENTION:

• Wear respiratory protection when spraying. Read all

instructions supplied with the mask to be sure it will provide

the necessary protection.

• All local regulations regarding protection against hazardous

vapors must be observed.

• Wear protective eyewear.

• Protective clothing, gloves and possibly skin protection cream

are necessary for the protection of the skin. Observe the

regulations of the manufacturer concerning coating materials,

solvents and cleaning agents in preparation, processing and

cleaning units.

HAZARD: GENERAL

This product can cause severe injury or property

damage.

PREVENTION:

• Follow all appropriate local, state, and national codes

governing ventilation, re prevention, and operation.

• Pulling the trigger causes a recoil force to the hand that is

holding the spray gun. The recoil force of the spray gun is

particularly powerful when the tip has been removed and

a high pressure has been set on the airless pump. When

cleaning without a spray tip, set the pressure control knob to

the lowest pressure.

• Use only manufacturer authorized parts. User assumes all

risks and liabilities when using parts that do not meet the

minimum specications and safety devices of the pump

manufacturer.

• ALWAYS follow the material manufacturer’s instructions for

safe handling of paint and solvents.

• Clean up all material and solvent spills immediately to prevent

slip hazard.

• Wear ear protection. This unit can produce noise levels above

85 dB(A).

• Never leave this equipment unattended. Keep away from

children or anyone not familiar with the operation of airless

equipment.

• Do not spray on windy days.

• The device and all related liquids (i.e. hydraulic oil) must be

disposed of in an environmentally friendly way.

1.2 Electric Safety

Electric models must be earthed. In the event of an electrical short

circuit, earthing reduces the risk of electric shock by providing an

escape wire for the electric current. This product is equipped with

a cord having an earthing wire with an appropriate earthing plug.

Connection to the mains only through a special feed point, e.g.

through an error protection insallation with INF < 30 mA.

DANGER — Work or repairs at the electrical

1.3 Gasoline Engine Safety

1. Gas engines are designed to give safe and dependable service

if operated according to instructions. Read and understand

the engine manufacturer’s Owner’s Manual before operating

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.

4. Know how to stop the engine quickly, and understand the

operation of all controls. Never permit anyone to operate the

engine without proper instructions.

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.

4 PowrTwin Plus

GB

Safety precautions

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.

9. Never run the engine in an enclosed or conned area. Exhaust

contains poisonous carbon monoxide gas; exposure may

cause loss of consciousness and may lead to death.

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.

11. Never ship/transport sprayer with gasoline in the tank.

DO NOT use this equipment to spray water or acid.

Attention

Do not lift by cart handle when loading or unloading.

Device is very heavy. Three-person lift is required.

1.4 Fueling (gas engine)

Gasoline is extremely flammable and is explosive

under certain conditions.

Attention

Do not overll the gas tank. Overlling can cause

the gas cap to become clogged with any particles

in the gasoline which can cause a vaccum. Read

the gas engine’s instruction manual for fueling

instructions.

Fuel Specications

• Use automotive gasoline that has a pump octane number of

86 or higher, or that has a research octane number of 91 or

higher. Use of a lower octane gasoline can cause persistent

“pinging” or heavy “spark knock” (a metallic rapping noise)

which, if severe, can lead to engine damage.

iIf “spark knock” or “pinging” occurs at a steady

engine speed under normal load, change brands of

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.

• Unleaded fuel produces fewer engine and spark plug deposits

and extends the life of the exhaust system components.

• Never use stale or contaminated gasoline or an oil/gasoline

mixture. Avoid getting dirt, dust, or water in the fuel tank.

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

contain co-solvents and corrosion inhibitors for methanol. Never

use gasoline containing more than 5% methanol, even if it has co-

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.

1.5 Setting up on uneven surfaces

The front side of the unit must point downwards to prevent sliding

away.

GB

General view of application Description of unit

2. General view of application

2.1 Application

Priming and nal coating of large areas, sealing, impregnation,

construction sanitation, façade protection and renovation, rust

protection and building protection, roof coating, roof sealing,

concrete sanitation, as well as heavy corrosion protection.

Examples of objects to be sprayed

Large-scale construction sites, cooling towers, bridges, sewage

treatment plants and terraces.

2.2 Coating materials

Processible coating materials

i

Pay attention to the Airless quality of the coating

materials to be processed.

Latex paint, dispersion paints, re protection and thick lm materials,

zinc dust and micaceous iron ore paints, Airless spray primer,

sprayable glue, anti-corrosive agents, thick coating materials and

bitumen-like coating materials.

No other materials should be used for spraying without Titan’s

approval.

Filtering

In spite of the high-pressure lter, ltering of the coating material is

to be recommended in general (except when processing airless joint

ller).

Stir coating material before commencement of work.

iMake sure when stirring with motor-driven agitators

that no air bubbles are stirred in. Air bubbles disturb

when spraying and can, in fact, lead to interruption

of operation.

Viscosity

It is possible to work with high-viscosity coating materials with the

devices.

If highly viscous coating materials cannot be sucked up, they must be

diluted in accordance with the manufacturer’s instruction.

Two-component coating material

The appropriate processing time must be adhered to exactly. Within

this time rinse through and clean the unit meticulously with the

appropriate cleaning agents.

Coating materials with sharp-edged additional materials

These have a strong wear and tear eect on valves, high-pressure

hose, spray gun and tip. The durability of these parts can be reduced

appreciably through this.

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 3300-3600 psi (228-248 bar, 24.4-24.8 MPa), the coating material is

atomised. This high pressure has the eect of micro ne atomisation

of the coating material.

As no air is used in this process, it is described as an AIRLESS process.

This method of spraying has the advantages of nest atomisation,

cloudless operation and a smooth, bubble-free surface. As well as

these, the advantages of the speed of work and convenience must be

mentioned.

3.2 Functioning of the unit

The following section contains a brief description of the technical

construction for better understanding of the function.

TITAN PowrTwin Plus (PT) are high-pressure spraying units driven by

either a gasoline engine or electric motor.

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 Speeo® HydraDrive™ 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 PTFE 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 PTFE 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.

4. Fill the oil cup 1/2 full with Piston Lube (P/N 314-480). This

extends packing life.

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

the engine manufacturer. Refer to the engine manufacturer’s

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

outlet. Use a short electric cable and a long paint hose. Any

extension cord will create some voltage drop. If an extension

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.

11. Locate the sprayer outside the immediate spraying area to

avoid clogged air intake of the engine or electric motor with

overspray.

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

Titan Coolo™ Hydraulic Fluid (P/N 430-361). Never add

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

3

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

set for which upper packing lubricant Piston Lube (P/N 314-480) is

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).

Maintenance

6.5 Basic Engine Maintenance (gas engine)

• For detailed engine maintenance and technical specications

refer to the separate gasoline engine manual.

• All service to the engine should be performed by a dealer

authorized by the engine manufacturer.

• Use a premium quality motor oil. 10W30 is recommended for

general all temperature use. Other viscosities may be required

in other climates.

• Use only a (NGK) BR-6HS (PT4900), or (NGK) BP6ES / BPR6E

spark plug (PT6900/PT8900/PT12000). Gap the plug to 0.028

to 0.031 In. (0.7 to 0.8 mm) Always use a spark plug wrench.

Daily

1. Check engine oil level, and ll as necessary.

2. Check gasoline level, and ll as necessary.

Always follow the fueling procedure outlined earlier

in this manual.

First 20 Hours

1. Change engine oil.

Every 100 Hours

1. Change engine oil.

2. Clean the sediment cup.

3. Clean and re-gap the spark plug.

4. Clean the spark arrestor.

Weekly

1. Remove the air lter cover and clean the element. In very

dusty environments, check the lter daily. Replace the

element as needed. Replacement elements can be purchased

from your local engine manufacturer dealer.

Engine Operation and Service

1. Clean and oil air lter pad on gasoline engine every 25 hours

or once weekly. Do not permit the air intake screen around

the y wheel of the gas engine to load up with paint or

trash. Clean it regularly. The service life and eciency of

the gas engine model depends upon keeping the gasoline

engine running properly. Change the oil in the engine

every 100 hours. Failure to observe this may result in engine

overheating. Consult the engine manufacturer’s service

manual provided.

2. To conserve fuel, service life, and eciency of the sprayer,

always operate the gasoline engine at the lowest RPM at

which it runs smoothly without laboring and delivers the

amount required for the particular painting operation.

Higher RPM does not produce higher working pressure. The

gasoline engine is connected to the hydraulic pump by a

pulley combination designed to produce full paint delivery at

maximum RPM.

3. The warranty on gasoline engines or electric motors is limited

to the original manufacturer.
