Operating Instructions

Gravity Feed 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 – 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-BleederIndicates 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-BleederIn 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 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

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)..

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..

Failure to install appropriate

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

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-strokewill cause a build up of paint and result in runs.. Do not fan the gun from side to side while painting.. This will cause abuild-upof paint in the center of the stroke and an

insufficient coating at each end (See Figure 9)..

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

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..

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-siliconeoil 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..

User - Maintenance Instructions

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 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..

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-ringsand 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-of-line.. 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..
