To reduce the risks of fire or explosion, electrical shock and the injury to persons, read and understand all instructions included in this manual. Be familiar with the controls and proper usage of the equipment.

HAZARD: INJECTION INJURY

A high pressure paint stream produced by this equipment can pierce the skin and underlying tissues, leading to serious injury and possible amputation. See a physician immediately

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

The maximum operating range of the sprayer is 3000 PSI / 20.6 MPa fluid pressure.

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 fluid stream. DO NOT allow body to touch 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 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 flushing 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 3000 PSI / 20.6 MPa. 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 fluid 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 with the mask to be sure it will provide the necessary protection.

ear protective eyewear.

• W

• 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 flammable vapors. Solvent and paint fumes can explode or ignite.

• Do not spray in a confined area.

• Avoid all ignition sources such as static electric sparks, open flames, pilot lights, electrical appliances, and hot objects. Connecting or disconnecting power cords or working light switches can make sparks. Paint or solvent flowing 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 flammable materials.

• Use only conductive or grounded high pressure fluid hose. Gun must be grounded through hose connections.

• For electric units — power cord must be connected to a grounded circuit.

• Always flush unit into a separate metal container, at low pump pressure, with spray tip removed. Hold gun firmly 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 flashpoint below 70ºF (21ºC). Flashpoint is the temperature that a fluid can produce enough vapors to ignite.

• Plastic can cause static sparks. Never hang plastic to enclose a spray area. Do not use plastic drop cloths when spraying flammable materials.

• Use lowest possible pressure to flush equipment.

• Do not spray onto pump assembly.

Grounding Instructions

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper installation of the grounding 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 grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin.

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

IMPORTANT: Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw in line voltage resulting in loss of power and overheating. A 12 gauge cord is recommended. If an extension cord is to be used outdoors, it must be marked with the suffix WA after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

IMPORTANT: When the sprayer is used with a generator or uncontrolled line voltage, the use of Titan’s “Line Surge Protector” (P/N 800-935) is recommended.

Be sure to follow the pressure relief procedure when shutting the unit down for any purpose, including servicing or adjusting any part of the spray system, changing or cleaning spray tips, or preparing for cleanup.

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

Turn off the sprayer by moving the ON/OFF switch to the OFF position.

3. Set the pressure to minimum by turning the pressure control knob fully counterclockwise.

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

5. 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.

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

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

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

Spraying

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%.

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 12 to 14 inches (30 to 35 cm).

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.

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. 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

Good spray pattern

Paint tailing pattern

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

9. Turn off the sprayer by moving the ON/OFF switch to the OFF position.

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

11. Turn on the sprayer.

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.

12. 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.

13.

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

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

mineral spirits 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).

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.

IMPORTANT: 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.

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

3. Place the siphon tube into a container of the appropriate solvent (refer to recommendations of the material manufacturer). An example of the appropriate solvent is water for latex paint.

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

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

NOTE: Hold the return hose in the waste

flush the paint out of the return hose into the metal waste container.

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

15. Unplug the sprayer and store in a clean, dry area.

IMPORTANT: 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.
