Do not smoke or

eat when spraying paint, insecticides, or other ﬂammable substances.

Keep hose away

from sharp objects. Bursting air hoses may cause injury. Examine air hoses regularly and replace if damaged.

Always work in a

clean environment. To avoid injury and damage to the workpiece, do not aim the spray gun at any dust or debris.

Keep visitors

away and NEVER allow children or pets in the work area.

PERSONAL SAFETY

a. Stay alert. Watch what you are

doing and use common sense when operating the tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of

inattention while operating the tool increases the risk of injury to persons.

b. Dress properly. Do not wear loose

clothing or jewelry. Contain long hair. Keep hair, clothing, and gloves away from moving parts.

Loose clothes, jewelry, or long hair increases the risk of injury to persons as a result of being caught in moving parts.

c. Do not attach the hose or tool to

your body. Attach the hose to the structure to reduce the risk of loss of balance if the hose shifts.

Use a

face mask / respirator and protective clothing when spraying. Always spray in a well ventilated area to prevent health and ﬁre hazards. Refer to Material Safety Data Sheets (MSDS) of spray material for details.

not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the spray gun in unexpected situations.

TOOL USE AND CARE

a. Use clamps or another practical way

to secure and support the workpiece to a stable platform. Holding the

work by hand or against the body is unstable and is able to lead to loss of control.

b. Store the tool when it is idle out

of reach of children and other untrained persons. A tool is

dangerous in the hands of untrained users.

Do not use pressure that exceeds operating pressure of the spray gun or any of the parts (hoses, ﬁttings, etc.) in the painting system.

Over pressurizing

the spray gun is able to result in bursting, abnormal operation, breakage of the spray gun or serious injury to persons.

Always verify

prior to using the spray gun that the air source has been adjusted to the rated air pressure or within the rated airpressure range.

Check for

misalignment or binding of moving parts, breakage of parts, and any other condition that affects the spray gun’s operation. If damaged, have the spray gun serviced before using. Many accidents are caused by poorly maintained spray guns. There is a risk of bursting if the spray gun is damaged.

Avoid

unintentional starting. Be sure the trigger is off before connecting to the air supply. Do not carry the spray gun with your ﬁnger on the trigger or connect the spray gun to the air supply with the trigger on.

Disconnect the

spray gun from the air source before, changing accessories, cleaning, servicing or storing the spray gun. Such preventive safety measures reduce the risk of starting the spray gun unintentionally.

Failure to install

appropriate water / oil removal equipment may result in damage to machinery or workpiece.

Always use a

pressure regulator on the air supply to the spray gun.

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 / Non-Bleeder – Indicates

whether air flows through the gun continuously or as the trigger is pulled.

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.

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.

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.

Mix – The mixing of paint and air when spraying.

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.

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.

Paint Tank – An auxiliary pressurized paint reservoir that allows continuous spraying of large amounts of paint without 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 workpiece.

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 a 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 compared 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 bounceback and overspray (See Figure 1). For these reasons, HVLP is also well suited for spraying parts with recessed areas.

Conventional

HVLP

Figure 1

Spray Gun Setup

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).

Operating Instructions

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. Set up 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 manufactuer’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.

WATER / OIL IN COMPRESSED AIR

All compressor pumps discharge some condensed water, oil or contaminates with the compressed air.

IMPORTANT: This condensation will cause “fish eyes” to appear in the paint job. Install appropriate water/oil removal equipment and controls as necessary for the intended application. Locate filter as close to spray gun as possible.

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).

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.

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.

Clean spray gun

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 PASSAGES 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 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 passages.

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-ofline. There are no adjustments that can be made to a bent gun body. 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.
