⚠WARNING

FAILURE TO HEED ALL WARNINGS COULD RESULT IN SEVERE PERSONAL OR

BYSTANDER INJURY, EVEN DEATH.

•ONLY USE TOOLS FOR PURPOSE THEY ARE INTENDED FOR.

• YOU MUST WEAR PROTECTIVE EYEWEAR AND SUITABLE RESPIRATORY

PROTECTION (OSHA APPROVED) WHILE SPRAYING OR CLEANING THIS GUN

OR ITS ATTACHMENTS.

• NEVER AIM SPRAY GUN AT PEOPLE. SOLVENTS AND THINNERS CAN CAUSE

INJURY.

• DO NOT EXCEED RATED OPERATING PRESSURE.

• CAUTION: POTENTIAL FLAMMABILITY OF SPRAYED PAINT, AND AVOID

SPRAYING NEAR FLAMESOR SPARKS.

• USE PAINT MASK/RESPIRATOR WHILE OPERATING PRODUCT.

• USE PRODUCT ONLY IN WELL-VENTILATED AREAS.

• WEAR EAR PROTECTORS.

⚠PERSONAL HAZARD WARNINGS

During cleaning and flushing, solvents can be forcefully expelled from fluid and air passages.

Some

solvents can cause eye injury. Be sure user and bystanders in the area are wearing impact

resistant eye and face protection. Even small projectiles can injure eyes and cause blindness.

Air under pressure can cause severe injury. Always shut off air supply, drain hose of air

pressure and disconnect tool from air supply when not in use, before changing accessories or

when making repairs. Never direct air at yourself or anyone else. Whipping hoses can cause

serious injury. Always check for damaged or loose hoses and fittings. Never use quick-change

couplings at tool. They add weight and could fail due to vibration. Instead, add a hose whip

and connect coupling between air supply and hose whip, between hose whip and leader hose

whip, or between hose whip and leader hose. DO NOT EXCEED MAXIMUM AIR

PRESSURE. Always use tool a safe distance from other people in work area. Maintain tools

with care. Keep tools clean and oiled for best and safest performance. Follow instructions for

lubricating and changing accessories. Wiping or cleaning rags and other flammable waste

materials must be placed in a tightly closed metal container and disposed of later in the

proper fashion.

Do not wear loose or ill-fitting clothing. Remove watches and rings. Do not overreach. Keep

proper footing and balance at all times. Slipping, tripping and falling can be a major cause of

serious injury or death. Be aware of excess hose left on the walking or work surface. Do not

abuse hoses or connectors. Never carry tool by the hose or yank it to disconnect from power

supply. Keep hoses from heat, oil and sharp edges. Check hoses for weak or worn condition

before each use, making certain that all connections are secure.

High sound levels can cause permanent hearing loss. Protect yourself from noise. Noise

levels vary with work surface. Wear ear protectors. When possible secure work with clamps

or vise so both hands are free to operate tool.

Repetitive work motions, awkward positions and exposure vibration can be harmful to hands

and arms. Avoid inhaling dust or handling debris from work processes, which can be harmful

to your health. Operators and maintenance personnel must be physically able to handle the

bulk, weight and power of the tool. This tool is not intended for using in explosive

atmospheres and is not insulated for contact with electric power sources. Solvent and

coatings can be highly flammable or combustible especially when sprayed. Adequate exhaust

must be provided to keep air free of accumulations of flammable vapors. Smoking must never

be allowed in the spray area. Fire extinguishing equipment must be present in the spray area.

Never spray near sources of ignition such as pilot lights, welders, etc.

Spray materials may be harmful if inhaled, or if there is contact with the skin. Adequate

exhaust must

be provided to keep the air free of accumulations of toxic materials. Use a mask or respirator

whenever there is a chance of inhaling sprayed materials. The mask must be compatible with

the material being sprayed and its concentration.

SPECIFICATIONS: DELUXE HVLP SPRAY GUN

Fluid Tip Size:

1.4 mm (9039629), 1.8 mm (9039637), 2.5 mm (9039645)

Air Inlet:

1/4” (6,35mm) NPT

Air Consumption:

11-13 CFM (60 PSI)

Capacity of Cup:

34 oz. (1000 ml)

Feed Type:

Gravity

Pressure Required:

30-43 PSI

AIR SUPPLY

Never mount oil and water extractor on or near the air compressor. During compression, air

temperature is greatly increased. As the air cools down to room temperature, moisture

condenses in the air line, on its way to the spray supply system where the compressed air

temperature is lowest. Drain air lines properly. Pitch all air lines back towards the compressor

so that condensed moisture will flow back into the air receiver where it can be drained off.

Each low point in an airline acts as a water trap. Such points should be fitted with an easily

accessible drain. See diagram above.

SPRAY GUN HANDLING

This spray gun is rugged in construction and is built to yield exceptional value. The life of this

product and the efficiency of its operation depend upon knowledge of its construction use and

maintenance.

FOR BEST PERFORMANCE, PLEASE BE SURE TO DO THE FOLLOWING BEFORE

USING THIS TOOL.

Tighten the gun to the cup securely with the nut and fitting supplied. Be sure to have the

proper air pressure at the gun to operate. Prior to shipment, this gun was treated with an

anticorrosive agent. Before using gun, make sure that it is carefully flushed with thinner.

Adjust fluid control screw and spray width adjustment knob to your desired pattern before

using on production. Clean all parts after use.

ADJUSTMENTS

Set atomization pressure at approximately 30 PSI for lacquer and 43 PSI for enamel. Try

spray. If spray is too fine, then decrease the air pressure or open fluid control screw. If the

spray is too thick, then close the fluid control screw. Regulate the pattern width and repeat

adjustment of spray as needed.

OPERATION

Proper handling of the gun is essential for obtaining a good finish. The gun should be held at

right angle to the surface being covered, moving parallel with the surface. For precise control

of the gun and material, the trigger should be released before the end of the stroke.

Hold the gun from 6 to 12 inches (15,24cm to 30,48cm) away from the surface depending on

material and atomizing pressure. For a uniform finish, lap each stroke over the preceding

stroke, making sure the spray is smooth and wet.

Using the lowest possible atomizing air pressure will reduce over-spray and provide maximum

efficiency.

CLEANING AND MAINTENANCE

⚠WARNING

RESPONSIBILITY. IT SHALL BE THE TOOL OWNER’S RESPONSIBILITY TO ASSURE

THAT TOOLS AREMAINTAINED IN A SAFE OPERATING CONDITION. IF TOOLS ARE

DAMAGED, REMOVE FROM SERVICEIMMEDIATELY.

AUTHORIZED PERSONNEL. TOOL MAINTENANCE AND REPAIR SHALL BE PERFORMED

BYAUTHORIZED, TRAINED, COMPETENT PERSONNEL.

REPAIRS. TOOLS SHALL BE DISCONNECTED FROM THEIR COMPRESSED AIR SUPPLY

BEFOREREPAIR IS ATTEMPTED. REPAIRS SHALL BE CONSISTENT WITH

MANUFACTURER’S RECOMMENDEDPROCEDURES. PLEASE REFER TO CLEANING

AND MAINTENANCE OR TROUBLESHOOTING SECTIONS.

REPLACEMENT. TOOLS, HOSES AND FITTINGS SHALL BE REPLACED IF UNSUITABLE

FOR SAFEOPERATION.

1. Submerge the front end of the gun in solvent just until the fluid connection is covered.

2. Paint that has built up on the gun should be removed using a bristle brush and solvent.

3. Never submerge all of the spray gun in solvent. This will dissolve the lubricant in the leather

packing and on wear surfaces, causing them to dry out and resulting in difficult operation and

faster wear. Air passages in the gun will become clogged with dirty solvent.

4. Using a rag moistened with solvent, wipe down the outside of the gun.

5. Oil gun daily. Use a drop of lightweight machine oil on: A. External Needle Pack Adjustment

(Packing Nut) See FIGURE 1 on page 4 for location of above point.

⚠CAUTION

DO NOT USE LUBRICANTS CONTAINING SILICONE.

SILICONE MAY CAUSE DEFECTS IN THE FINISH APPLICATION.

ALL PARTS ON A SPRAY GUN SHOULD BE SCREWED IN BY HAND AT FIRST.

THIS WILL AVOID THE POSSIBILITY OF CROSS THREADING THE PARTS. IF THE PARTS

CANNOT BE TURNED BY HAND EASILY, MAKE SURE YOU HAVE THE CORRECT PARTS,

UNSCREW, REALIGN, AND TRY AGAIN. NEVER USE UNDUE FORCE IN MATING PARTS.

SERVICE

•Tool service must be performed only by qualified repair personnel. Service or maintenance

performed by unqualified could result in a risk of injury.

•When servicing a tool, use only identical replacement parts. Follow instructions in the

Maintenance section of this manual. Use of unauthorized parts or failure to follow

Maintenance Instructions may create a risk of electrical shock or injury.
