Introduction

The spray gun is a vital link in any finishing application. In addition to operating the spray gun properly, techniques of surface preparation and paint preparation must be understood. These instructions will explain the differences among various spray technologies and serve as a guide in the proper operation and techniques of spray painting. Refer to the Replacement Parts Manual for model specific information.

SPRAY GUN TERMS

Atomization - Conversion of bulk liquid to spray droplets (mist).

Bleeder – In this mode, air passes continuously through the gun whether spraying or not. This mode is generally used when the air is supplied by a continuously running compressor that does not have a tank.

Bleeder/Non-Bleeder – Indicates whether air flows through the gun continuously or as the trigger is pulled.

External Mix – Process where the air and paint are mixed just after leaving the nozzle. This type of mix should be used for fast drying paints and when a high quality finish is needed.

Feed – Method used to bring paint into the gun for spraying.

Fluid Control Knob – Used to control the amount of paint being mixed with air.

Gravity Feed – Method of paint feed similar to the siphon feed method.

However, the cup is inverted to create a positive fluid pressure at the nozzle.

Internal Mix – Process where the air and paint are mixed inside the air cap just before being sprayed. This method is best for heavy bodied, slow drying paints and can only be used with the pressure feed method. Do not use fast drying paints with internal mix. The paint will dry inside and quickly clog the air cap.

Mix – The mixing of paint and air when spraying.

Non-Bleeder – In this mode, air flows only when the trigger is pulled. This type of operation is used with a compressor equipped with a tank or with a large factory air system.

Paint Tank – An auxiliary pressurized paint reservoir that allows continuous spraying of large amounts of paint with- out stopping for refills as with a canister.

It also allows using the spray gun at any angle without causing paint to drip.

Pattern Control Knob – Used to form the proper pattern (size and shape) of paint as it is sprayed from the gun to the work-piece.

Pressure Feed – Method of paint feed where a canister or paint tank is pressurized to force paint to the gun. Either internal or external mix air caps are

used with this method. Pressure feed is generally used for spraying heavy bodied paints or for large size projects.

Siphon Feed – Method of paint feed where atmospheric pressure creates a partial vacuum to siphon paint to the gun. Only external mix air caps are used with this method. Siphon feed is used with light bodied paints.

Viscosity – A measurement of the resistance to the flow of liquids.

CONVENTIONAL VS HVLP

Conventional spray guns use a much higher air cap pressure to atomize paint than HVLP spray guns. This results in more overspray and lower transfer efficiency.

HVLP, electrostatic and airless processes are currently the only compliant spray methods that meet the strict 65% transfer efficiency criteria required by some air quality management districts. This enhanced transfer efficiency results in a significant material savings com- pared to conventional spraying. Check local, state and national regulations that may be in effect before performing any spraying operations.

HVLP spraying is a growing trend in the finishing industry due to its environmental friendliness. By definition, dynamic air pressures in the air cap must be

10 psi or less to qualify as HVLP. A soft, low velocity pattern is produced which increases control and reduces bounce-back and overspray (See Figure 1). For these reasons, HVLP is also well suited for spraying parts with recessed areas.

Spray Gun Set-up

The pressure for atomization is controlled at the air source. The amount of fluid is adjusted by the fluid control knob, the paint viscosity and the air pressure.

The gravity feed cup screws onto the top of the gun body creating a positive fluid pressure in the nozzle

(See Figure 2).

PREPARATION

1. Thoroughly mix and thin paint in accordance with the paint manufacturer’s instructions. Most materials will spray readily if thinned properly.

2. Strain material through cheese cloth or a paint strainer.

3. Fill the canister about 3/4 full and start the air compressor.

4. Setup a piece of cardboard or other scrap material to use as a target and adjust for best spray pattern.

5. Test the consistency of the material by making a few strokes on a cardboard target. If material still appears too thick, add a small amount of thinner. THIN WITH CARE!! Do not exceed paint manufacturer’s thinning recommendations.

FAN DIRECTION

The direction of the fan (horizontal or vertical) can be changed by loosening the lock ring and turning the air cap 90 degrees (See Figure 3). Hand tighten lock ring after adjustment.

PATTERN ADJUSTMENT

1. Adjust air pressure to the spray gun according to the recommendations supplied with the spray material. This air pressure usually falls between 40 - 60 psi.

WARNING!

DO NOT EXCEED SPRAY GUN MAXIMUM PRESSURE.

Adjust air pressure with the trigger pulled and air control knob (if applicable) fully open. If reduced air pressure is desired for some areas of the spray job, use the air compressor regulator or air control knob to reduce pressure as necessary (See Figure 4).

2. Set pattern size to desired shape. For full pattern, open pattern control knob by turning counterclockwise. For a round pattern, turn pattern control knob clockwise (See Figure 6).

3. Turn fluid control knob fully clockwise until closed (See Figure 6).

4. Trigger a short burst while turning fluid control knob counterclockwise. Observe the spray pattern on the target and adjust the fluid control knob until the desired pattern (atomization) is obtained

(See Figure 7).

If the spray is too fine (excessive over-spray), caused by too much air for the amount of paint being sprayed, reduce the air pressure or open the fluid control to spray more material.

If the spray is too coarse (spitting globs), reduce the amount of material with the fluid control knob or thin the paint.

5. The fluid control knob can be used to finely adjust pattern consistency.

Before spraying the work-piece, practice a few minutes on a cardboard target to ensure the pattern size and consistency are set correctly.

Operation

1. Begin spraying. Always keep the gun at right angles to the work (See Figure 8).

2. Keep the nozzle about 6 to 9 inches from the work surface throughout the stroke and always keep the gun in motion while spraying. Stopping gun movement in mid-stroke will cause a build-up of paint and result in runs. Do not fan the gun from side to side while painting. This will cause a build-up of paint in the center of the stroke and an insufficient coating at each end (See

Figure 9).

3. Trigger the gun properly. Start the gun moving at the beginning of the stroke

BEFORE SQUEEZING THE TRIGGER and release the trigger BEFORE

STOPPING GUN MOVEMENT at the end of the stroke. This procedure will feather (blend) each stroke with the next without showing overlap or unevenness (See Figure 10).

4. The amount of paint being applied can be varied by the speed of the stroke, distance from the surface and adjustment of the fluid control knob.

5. Overlap strokes just enough to obtain an even coat (See Figure 11).

NOTE:

Two thin coats of paint will yield better results and have less chance of runs than one heavy layer.

6. Use a piece of cardboard as a shield to catch overspray at the edges of the work to protect other surfaces. Use masking tape to cover other areas if needed.

Maintenance

DAILY CLEAN-UP

Local codes may require specific cleaning methods and equipment. Follow local codes and paint manufacturer’s recommendations for the use and disposal of spray materials and solvent.

CAUTION:

CLEAN SPRAY GUN IMMEDIATELY AFTER USE. PAINT AND

OTHER MATERIALS DRY QUICKLY IN THE SMALL PASSAGES

RENDERING GUN USELESS DUE TO THE DIFFICULTY OF

REMOVING HARDENED PAINT FROM THE PASSAGES INSIDE

THE GUN.

NOTE:

In the instructions below, the use of the word “solvent” refers to the specific solvent for the material used (example: lacquer thinner for lacquer, etc.).

1. Remove and empty the canister; then rinse with a solvent recommended for the paint or other material used.

2. Refill canister with clean solvent and attach to the gun. Spray solvent through the gun while shaking the gun vigorously. Wipe the gun exterior with a solvent soaked rag. Repeat until the gun is clean.

3. Remove the air cap and soak in solvent until clean. Use a small brush for stubborn stains if necessary. Toothpicks or small brushes may be used to clean air passages; however, NEVER USE METAL

OBJECTS TO CLEAN PRECISELY DRILLED PASSAGES.

DAMAGED PAS- SAGES WILL CAUSE IMPROPER SPRAYING.

4. Clean gaskets with a solvent soaked rag. To prevent equipment damage, DO NOT IMMERSE GASKETS OR SPRAY GUN BODY IN

SOLVENTS.

5. After using water to clean out water based paints or materials, spray mineral spirits through the gun to prevent corrosion.

6. Use a non-silicone oil on all moving parts when reassembling. Use

Vaseline® or light grease on all threaded connections prior to storage.

7. Clean and flush gun thoroughly to neutralize any contaminants corrosive to the spray gun.

PERIODIC CLEAN-UP

Due to improper cleaning and paint it may be necessary to inspect and clean the internal parts and the gun body.

1. Examine openings in air cap and fluid tip. If clogged, remove any o- rings and soak the air cap or fluid tip in solvent.

2. A brush or toothpick or something similar may be used to dislodge the dried paint from holes and pas- sages. NEVER USE METAL

OBJECTS TO CLEAN PRECISELY DRILLED PASSAGES.

DAMAGED PASSAGES WILL CAUSE IMPROPER SPRAYING.

3. Remove and check the fluid needle for excessive wear at the tip and straightness.

IMPORTANT: If the needle tip is worn more on one side than the other, either the needle is bent or the gun body has been dropped or knocked out-of-line.

There are no adjustments that can be made to a bent gun

Test the needle by rolling on a flat surface. Replace if necessary.

4. Check and replace any damaged o- rings and seals. O-rings and seals can be wiped clean but not soaked in solvent.

5. Unscrew packing nuts and replace the packing ONLY if a leak will not stop when the nut is tightened (See Figure 5). Do not over-

tighten a packing nut because this will restrict movement of the needle.

6. Re-assemble in reverse order of above and use a non-silicone oil on moving parts. Apply Vaseline® or light grease on threaded joints and hose connections.

STORING

1. When not using spray gun, turn the fluid adjustment knob counterclockwise to open which will reduce spring tension on needle fluid tip.

2. Spray gun MUST BE well cleaned and lightly lubricated.
