Safety Precautions

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.

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.

Airless units develop extremely high spraying pressures.

• Never put your fingers, hands or any other parts of the body into the spray jet.

• Never point the spray gun at yourself or anybody else.

• Never use the spray gun without the safety guard.

NOTE: Notes give important information which should

be given special attention.

CAUTION

Attention! Danger of injury by injection!

In case of injury to skin caused by coating materials or solvents consult a doctor immediately. Inform the doctor of the type of coating material or cleaning agent with which the injury was caused.

The operating instructions state that the following points must always be observed before starting up:

1. Faulty units should not be used.

2. Secure spray gun using the safety catch on the trigger.

3. Ensure that the unit is properly earthed.

4. Check the permissible operating pressures.

5. Check all connections for leaks.

The instructions regarding regular cleaning and maintenance of the unit must be strictly observed.

Before any work is done on the unit or for every break in work the following rules must be observed:

1. Release the pressure from the spray gun and hose.

2. Secure the spray gun using the safety catch on the trigger.

3. Turn off the motor.

Be safety-conscious! All local regulations in force must be observed. In order to ensure safe operation of the airless systems

the safety regulations listed below must be followed:

1. In order to avoid dangers, read the operating instructions carefully and follow the instructions laid down in them.

2. Do not use materials with a flash point below 21ºC (70ºF).

3. The use of this unit is prohibited in workshops which are covered under the explosion prevention regulations.

4. Never spray near sources of ignition; e.g. open flames, cigarettes — also cigars and pipes are sources of ignition — sparks, hot wires and hot surfaces, etc.

5. Attention! Danger of injury by injection! Never point the spray gun at yourself or anyone else. Never put your fingers or hands into the spray jet. The

very high spraying pressures can cause very serious injuries. Never use the spray gun without the safety guard.

When installing and removing the tip and during breaks in work the spray gun must always be secured, so that it cannot be activated.

6. Wear respiratory equipment when spraying. The operator must be provided with a protective mask.

In order to prevent work related illness, the manufacturer's regulations for the materials, solvents, and cleaning agents used must be observed when preparing, working with and cleaning the unit. Protective clothing, gloves and, in certain cases, protective skin cream are necessary to protect the skin.

7. The spray gun and high pressure hose between the unit and spray gun must be of a sufficient standard for the pressure produced in the unit.

The permissible operating pressure for the high-pressure hose, the manufacturer and date of manufacture must be indicated by a permanent identification marking on the hose. Furthermore, it must be constructed so that the electrical resistance between the connections to the unit and the spray gun is equal to or less than one megohm.

8. Under certain conditions the flow speed can cause an electrostatic charge on the unit. This could cause sparks or flames on discharging. It is, therefore, important that the unit is always earthed over the electrical installation. The contact should be made using a shockproof socket earthed in accordance with the regulations.

WARNING

9. Attention! Please observe the following when working inside and outside:

No solvent gasses should be carried to the unit. No solvent gasses should form near the unit. Set up the unit on the opposite side to the object being sprayed. When spraying outdoors, take the wind direction into account. When working indoors there must be sufficient ventilation to ensure that the solvent gasses are carried away. A minimum distance of 6.1m (20’) must be observed between the unit and object being sprayed.

10. Extraction equipment should be installed by the user in accordance with the local regulations.

11. The objects being sprayed must be earthed.

12. When cleaning the unit, solvent should never be sprayed into a container with only a small opening (bunghole). An explosive gas/air mixture is likely to form. The container must be earthed.

13. Cleaning the unit. A harsh jet should never be used to spray the unit. In

particular a high-pressure cleaner or high-pressure steam cleaner should never be used. There is a danger that water will penetrate into the unit and cause a short-circuit.

14. 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 high-pressure pump. Therefore, when cleaning without tip set the pressure control valve to the lowest pressure.

15. The mains plug should always be disconnected from the socket when work is being carried out on the electrical components.

16. Work or repairs should only be carried out on electrical equipment by a trained electrician, even if the work is described in the operating instructions. No liability will be accepted for incorrectly installed electrics.

17. Positioning when the ground is uneven. The front of the unit must point downward so that the

machine does not slip away.

HAZARD: INJECTION INJURY - A high pressure stream

of paint produced by this equipment can pierce the skin and underlying tissues, leading to serious injury and possible amputation.

PREVENTION:

• The maximum operating range of the unit is 228 BAR (3300 PSI) fluid pressure.

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

• NEVER allow any part of the body to come in contact with the fluid stream. DO NOT come in contact with a fluid stream created by a leak in the fluid 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 fluid pump off and release all pressure before servicing, cleaning the tip guard, changing tips, or leaving unattended. Pressure will not be released by turning off the engine. The PRIME/SPRAY knob must be turned to PRIME to relieve the pressure. Refer to the PRESSURE RELIEF PROCEDURE described in this manual.

• The tip guard must always be in place while spraying. The tip guard provides some protection against injection injuries but is mainly a warning device.

•ALWAYS remove the spray tip before flushing or cleaning the system.

• The paint hose can develop leaks from wear, kinking and abuse. A leak is capable of injecting material into the skin. Inspect the paint hose before each use.

DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT! Injection can lead to amputation. See a physician immediately.

HAZARD: EXPLOSION OR FIRE - Solvent and paint fumes

can explode or ignite, causing property damage and/or severe injury.

PREVENTION:

• Fire extinguishing equipment must be present and in good working order.

• Use only conductive or earthed high pressure fluid hoses for airless applications. Be sure that the gun is earthed properly through hose connections.

• The pump must be connected to an earthed object. Use the green earthing wire to connect the pump to a water pipe, steel beam, or other electrically earthed surface.

• When flushing equipment use the lowest possible pressure.

HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE

MATERIALS- May cause property damage or severe injury.

PREVENTION:

• Do not use bleach.

• Do not use halogenated hydrocarbon solvents such as methylene chloride and 1,1,1 - trichloroethane. They are not compatible with aluminum and may cause an explosion. If you are unsure of a material’s compatibility with aluminum, contact your coating's supplier.

HAZARD: GENERAL - May cause property damage or

severe injury.

PREVENTION:

• This high pressure airless pump is designed to be used with manufacturer authorized parts only. When using this pump with parts that do not comply with the minimum specifications and safety devices of the pump manufacturer, the user assumes all risks and liabilities.

• Before each use, check all hoses for cuts, leaks, abrasion or bulging of cover, as well as damage or movement of couplings. If any of these conditions exist, replace the hose immediately. Never repair a paint hose. Replace it with another earthed hose.

•Wear protective eyewear.

• Do not spray on windy days.

Earthing Instructions

This product 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. The plug must be plugged into an outlet that is properly installed and earthed in accordance with all local codes and ordinances.

DANGER — Improper installation of the earthing plug can result in a risk of electric shock.

If repair or replacement of the cord or plug is necessary, do not connect the green earthing wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the earthing wire and must be connected to the earthing pin.

Check with a qualified electrician or serviceman if the earthing instructions are not completely understood, or if you are in doubt as to whether the product is properly earthed. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

NOTE TO PHYSICIAN:

Injection into the skin is a traumatic injury. It is important to treat the injury surgically 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.

General Description

This airless sprayer is a precision power tool used for spraying many types of materials. Read and follow this instruction manual carefully for proper operating instructions, maintenance, and safety information.

Electronic Pressure Control Indicators

The following is a description of the electronic pressure control indicators.

Pressure Indicator

The pressure indicator shows the current operating pressure of the sprayer. It has three different indications: blinking yellow, solid yellow, and solid green.

Blinking Yellow

When the pressure indicator is blinking yellow, the sprayer is operating between 0 and 14 bar (200 PSI). A blinking yellow pressure indicator means:

• The sprayer is plugged in and turned “ON”.

• The sprayer is at priming pressure (little or no pressure).

• It is safe to move the PRIME/SPRAY valve between positions.

• It is safe to change or replace the spray tip (refer to gun manual for tip replacement instructions).

NOTE: If the pressure indicator begins blinking yellow

when the pressure control knob is set at a higher pressure and the PRIME/SPRAY valve is in the SPRAY position, either the spray tip is worn, there is a leak, or the sprayer is in need of service/repair.

WARNING

Solid Yellow

When the pressure indicator is solid yellow, the sprayer is operating between 14 and 124 bar (200 and 1800 PSI). A solid yellow pressure indicator means:

•The sprayer is at the proper pressure setting for spraying stain, lacquer, varnish, and multi-colors.

• If the pressure indicator goes to solid yellow when the pressure is set so that it starts at solid green, it indicates one of the following:

a. Tip Wear Indicator — when spraying with latex or at

high pressure the solid yellow appears. This means the tip is worn and needs to be replaced.

b. Tip Too Large — when a tip that is too large for the

sprayer is put in the gun, the pressure indicator will turn from solid green to solid yellow.

c. Fluid Section Wear — if a solid yellow pressure

indicator appears when using a new tip and the pressure is set at maximum, service may be required (worn packings, worn piston, stuck valve, etc...).

Solid Green

When the pressure indicator is solid green, the sprayer is operating between 124 and 228 bar (1800 and 3300 PSI). A solid green pressure indicator means:

•The sprayer is at the proper pressure setting for spraying oil-based and latex house paints.

• The sprayer is operating at peak performance at a high pressure setting.

Motor Running Indicator

The Motor Running indicator is on when the motor is commanded to run. This indicator is used by service centers to troubleshoot motor problems.

Pressure Relief Procedure

1. Lock the gun by turning the gun trigger lock to the locked position.

2. Turn the pressure control knob counterclockwise to its OFF position in the black zone.

3. Unlock the gun by turning the gun trigger lock to the unlocked position.

4. Hold the metal part of the gun firmly to the side of a metal container to ground the gun and avoid a build up of static electricity.

5. Trigger the gun to remove any pressure that may still be in the hose.

6. Lock the gun by turning the gun trigger lock to the locked position.

7. Move the PRIME/SPRAY valve down to the PRIME position.

Spraying

NOTE: When spraying block fillers, mastics, or high

solid coatings, remove the gun filter and the high pressure filter.

Spraying Technique

The following techniques, if followed, will assure professional painting results.

Hold the gun perpendicular to the surface and always at equal distance from the surface. Depending on the type of material, surface, or desired spray pattern, the gun should be held at a distance of 30 to 35 cm (12 to 14 inches).

Move the gun either across or up and down the surface at a steady rate. Moving the gun at a consistent speed conserves material and provides even coverage. The correct spraying speed allows a full, wet coat of paint to be applied without runs or sags.

Holding the gun closer to the surface deposits more paint on the surface and produces a narrower spray pattern. Holding the gun farther from the surface produces a thinner coat and wider spray pattern. If runs, sags, or excessive paint occur, change to a spray tip with a smaller orifice. If there is an insufficient amount of paint on the surface or you desire to spray faster, a larger orifice tip should be selected.

Maintain uniform spray stroke action. Spray alternately from left to right and right to left. Begin movement of the gun before the trigger is pulled.

Avoid arcing or holding the gun at an angle. This will result in an uneven finish.

Proper lapping (overlap of spray pattern) is essential to an even finish. Lap each stroke. If you are spraying horizontally, aim at the bottom edge of the preceding stroke, so as to lap the previous pattern by 50%.

WARNING

For corners and edges, split the center of the spray pattern on the corner or edge and spray vertically so that both adjoining sections receive approximately even amounts of paint.

When spraying with a shield, hold it firmly against the surface. Angle the spray gun slightly away from the shield and toward the surface. This will prevent paint from being forced underneath.

Shrubs next to houses should be tied back and covered with a canvas cloth. The cloth should be removed as soon as possible. Titan gun extensions are extremely helpful in these situations.

Nearby objects such as automobiles, outdoor furniture, etc. should be moved or covered whenever in the vicinity of a spray job. Be careful of any other surrounding objects that could be damaged by overspray.

Practice

1. Be sure that the paint hose is free of kinks and clear of objects with sharp cutting edges.

2. Turn the pressure control knob counterclockwise to its to its lowest setting.

3. Turn the PRIME/SPRAY valve up to its SPRAY position.

4. Turn the pressure control knob clockwise to its highest setting. The paint hose should stiffen as paint begins to flow through it.

5. Unlock the gun trigger lock.

6. Trigger the spray gun to bleed air out of the hose.

7. When paint reaches the spray tip, spray a test area to check the spray pattern.

8. Use the lowest pressure setting necessary to get a good spray pattern. If the pressure is set too high, the spray pattern will be too light. If the pressure is set too low, tailing will appear or the paint will spatter out in gobs rather than in a fine spray.

Cleanup

Special cleanup instructions for use with flammable solvents:

•Always flush spray gun preferably outside and at least one hose length from spray pump.

• If collecting flushed solvents in a one gallon metal container, place it into an empty five gallon container, then flush solvents.

• Area must be free of flammable vapors.

• Follow all cleanup instructions.

The sprayer, hose, and gun should be cleaned thoroughly after daily use. Failure to do so permits material to build up, seriously affecting the performance of the unit.

Always spray at minimum pressure with the gun nozzle tip removed when using mineral spirits or any other solvent to clean the sprayer, hose, or gun. Static electricity buildup may result in a fire or explosion in the presence of flammable vapors.

1. Follow the “Pressure Relief Procedure” found in the Operation section of this manual.

2. Remove the gun tip and tip guard and clean with a brush using the appropriate solvent.

CAUTION

3. Place the siphon tube into a container of the appropriate solvent. Examples of the appropriate solvent are water for latex paint or mineral spirits for oil-based paints.

4. Place the return hose into a metal waste container.

5. Move the PRIME/SPRAY valve down to its PRIME position.

6. Turn the unit on and set the pressure to Turbo PulseClean by turning the pressure control knob to its CLEAN position in the red zone.

7. Allow the solvent to circulate through the unit and flush the paint out of the return hose into the metal waste container.

8. Turn the unit off by moving the pressure control knob to the OFF position in the black zone.

9. Move the PRIME/SPRAY valve up to its SPRAY position.

10. Turn the unit on and set the pressure to Turbo PulseClean by turning the pressure control knob to its CLEAN position in the red zone.

Ground the gun by holding it against the edge of the metal container while flushing. Failure to do so may lead to a static electric discharge, which may cause a fire.

11.Trigger the gun into the metal waste container until the paint is flushed out of the hose and solvent is coming out of the gun.

12. Continue to trigger the spray gun into the waste container until the solvent coming out of the gun is clean.

13. Follow the “Pressure Relief Procedure” found in the Operation section of this manual.

14. Unplug the unit and store in a clean, dry area.

Do not store the unit under pressure.

Cleaning the Spray Tip

1. Flush the gun with solvent immediately after the work is completed.

2. Oil the retractor pins to prevent them from seizing up.

Should the spray tip become clogged, reverse the spray tip with the lever and pull the trigger. Once the obstruction comes out of the spray tip, release the trigger, reverse the spray tip back to the spray pattern setting, and resume spraying.

Do not attempt to clean the tip with your finger. Do not use a needle or other sharp pointed instrument to

clean the tip. The hard tungsten carbide is brittle and can be chipped.

CAUTION

NOTE: For long-term or cold weather storage, pump

mineral sprits through the entire system. For short-term storage when using latex paint,

pump water mixed with Titan Liquid Shield Plus through the entire system (see the Accessories section of this manual for part number).
