Safety precautions

1. Safety regulations for Airless spraying

1.1 Explanation of symbols used

This manual contains information that must be read and understood

before using the equipment. When you come to an area that has one

of the following symbols, pay particular attention and make certain

to heed the safeguard.

This symbol indicates a potential hazard that

may cause serious injury or loss of life. Important

safety information will follow.

At

tention

This symbol indicates a potential hazard to you

or to the equipment. Important information that

tells how to prevent damage to the equipment or

how to avoid causes of minor injuries will follow.

Danger of skin injection

Danger of fire from solvent and paint fumes

Danger of explosion from solvent, paint fumes

and incompatible materials

Danger of injury from inhalation of harmful

vapors

i

Notes give important information which should

be given special attention.

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 1MΩ.

• 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.

• 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.

• 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.

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

portable electric lamps and plastic drop cloths (potential static

arc).

• 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 grounding chain is in place and reaches the

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.

PowrLiner 3

GB

Safety precautions

• 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 grounded/earthed. In the event of an

electrical short circuit, grounding/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 grounding/earthing

Safety precautions

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.

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.

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.

i

If “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.

i

Fuel 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.

General view of application Description of unit

2. General view of application

2.1 Application

This airless line striper is a precision power tool used to spray many

types of material for many types of applications including parking

lots, curbs, and athletic elds. Read and follow this instruction manual

carefully for proper operating instructions, maintenance, and safety

information.

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

recommended in general.

Mix coating material before commencement of work.

i

Make 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. A

minimum of 45 minute set time is recommended. 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 227 bar (22.7 MPa, 3300 PSI), the coating material is atomized. 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 PowrLiner (PL) 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 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 atomizes.

The pressure control valve (6) controls the volume and the operating

pressure of the coating material.

Operation

Attention

Always disengage the trigger cable from the

tensioning clamp before making any adjustments to

the spray gun position.

b. Loosen the support bar clamps and slide the gun support bar

to the desired horizontal position.

c. Loosen the gun riser clamp and slide the spray gun to the

desired vertical position.

i

The height of the spray gun aects the width of the

spray pattern (i.e., the lower the gun, the smaller the

line width). Tip size also aects line width.

4. Repeat steps 3a through 3c for the second spray gun.

i

It is recommended that both spray guns be installed

at the same height as a starting point. The gun

heights can be adjusted individually based on

spraying needs (i.e. spraying a curb or spraying two

lines of dierent widths).

5. Once both guns are installed, their vertical position can be

adjusted simultaneously.

a. Loosen the vertical support clamp knob (g. 5, item 1) on the

riser.

b. Turn the crank (2) to adjust the overall height of the spray guns.

c. Once at desired height, re-tighten the vertical support clamp

knob (1).

6. Set the trigger selector for proper spray gun operation (g.

6). The right handlebar triggers the gun or guns. The selector

on the trigger must be set for the rst gun, both guns, or the

second gun .

Attention

Always turn the trigger lock on the spray gun to the

locked position before making any adjustments to

the trigger selector. Also, release the trigger cable

from its block by lifting the cable up and out of the

block. There will be a brief triggering of the gun

while releasing the trigger cable.

i

If lift/tilt assembly has excessive friction during

operation, spray the tubes with dry graphite

lubricant.

a. First Gun — The rst gun position is with the selector in the

left position. Push the lever toward the inside of the frame until

the pin engages the left plate.

b. Both Guns — The dual gun position is with the selector in the

center position. Push the lever toward the center position until

the pin engages both plates. The pin must engage both plates.

c. Second Gun — The second gun position is with the selector in

the right position. Push the lever away from the inside of the

frame until the pin engages the right plate.

ABC

7. 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.

8. 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.

9. 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.

10. 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.

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.

11. Make sure the sprayer is grounded/earthed. All sprayers are

equipped with an grounding/earthing chain. Make sure

the chain reaches all the way to the ground. Check your

local electrical regulations for detailed grounding/earthing

instructions.

Proper grounding/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.

12. Strain all paints with a nylon strainer to ensure trouble free

operation and freedom from frequent cleaning of the inlet

screen and gun lter.

13. Make sure the spray area is well ventilated to prevent

hazardous operation with volatile solvents or exhaust fumes.

lter body (4).

6. Place the thick PTFE gasket (7) onto the top of the thin gasket

(8).

7. Tighten the lter cap assembly (1) onto the lter body (4).

6.3 Maintaining the Hydraulic System

Attention

Use of Titan’s Coolflo™ Hydraulic Fluid is mandatory

in the PowrLiner 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. 18, 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.

3

1

2

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.

i

When 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).

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) BP6ES / BPR6E spark plug. 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.

6.8 Replacing the Belt (Fig. 24)

Before replacing the belt on your unit, make sure

you have performed the “Pressure Relief Procedure”

as illustrated in the Operation section of this manual.

DO NOT attempt this repair while the unit is running.

i

The graphics below show a unit with a gas engine.

All instructions given in this section will apply to

both gas engine models and electric motor models

except where noted.

1. Loosen the bolt (1) on the front of the belt guard. Lift open

the front end of the belt guard (2) so that the front end of the

belt (3) is exposed.

2. Gently lift the front end of the gas engine / electric motor.

This will loosen the tension on the belt and make it easier to

remove.

PINCH HAZARD. Make sure your fingers remain clear

of the gas engine / electric motor mounting plate.

BURN HAZARD. Make sure the gas engine has had

time to sufficiently cool before touching it.

3. While the gas engine / electric motor is lifted up, remove the

belt from the front (4) and rear (5) pulleys.

4. Install the new belt:

a. Insert the belt into the xed section of the belt guard (6). Loop

the belt over the rear pulley (5) until the belt engages the

pulley groove.

b. Gently lift the front end of the gas engine / electric motor.

c. With the front end of the gas engine / electric motor lifted, loop

the other end of the belt around the front pulley (4).

d. Gently set the the gas engine / electric motor down. The

weight of the gas engine / electric motor will create tension in

the belt and prevent it from coming o.

Attention

Make sure the belt is not pinched or twisted in any

way once you have set the gas engine / electric

motor back into place.

e. Close the belt guard (2) and tighten the belt guard bolt (1).

Refer to the ”SAE O-Ring Fitting Installation”

procedure at the end of this section for installation

instructions for item 22 and 24.

Perform this procedure using the necessary parts from Motor Service

Kit — Minor (P/N 235-050). If the hydraulic motor is operable, start

the machine and jog the piston rod (19) into its top position.

i

Servicing of the hydraulic motor should be carried

out in a clean, dust free area only. Any dust or

metallic particles left in the motor or entering it on

reassembly may damage the critical parts and aect

its service life and warranty. All parts should be
