JGA-504 CONVENTIONAL SPRAY GUN

Note

Protective coating and rust inhibitors

have been used to keep the gun

in good condition prior to shipment.

Before using the gun, flush it with

solvents so that these materials will

be removed from fluid passages.

OPERATION

Mix, prepare and strain the material to be

sprayed according to the paint

manufacturer's instructions.

Strain material through a 60 or 90 mesh

screen.

1. Fill the suction or pressure feed cup

with the material. Do not overfill. Make

sure that the cup lid vent hole is clear,

if using a suction cup.

2. Turn on the gun air at the source of

supply. Adjust the atomization air pres-

sure to 35 psi.

3. Turn on the supply air to the pressure

cup if used.

4. Open the spreader adjustment valve

(10) (Fan) by turning the valve stem

counter-clockwise.

5. Open the fluid needle adjusting screw

(17) by turning counter-clockwise.

6. Spray a test area.

If the finish is too sandy and dry, the

material flow may be too low for the atomi-

zation air pressure being used.

If the finish sags, there is too much material

flowing for the atomization air pressure

being used.

Both of the above can be corrected by

increasing or decreasing the atomization

air pressure or the material flow. Pattern

width can be altered by turning the spreader

adjustment valve (10), either clockwise to

decrease the width or counter-clockwise

to increase the width.

See Spray Gun Guide SB-2-001 (latest

revision) for details concerning set up of

spray guns.

DESCRIPTION

The standard JGA-504 spray gun is a general

purpose, heavy duty, high production

spray gun suitable for use with most types

of materials. The fluid passageway is

plated brass and aluminum. The fluid tip

and needle are 300 series stainless steel.

Halogenated hydrocarbon solvents

- for example; 1, 1, 1 - trichloroethane

and methylene chloride - can chemi-

cally react with the aluminum in

this gun and cause an explosion

hazard. Read the label or data sheet

for the material you intend to

spray. Do not use spray materials

containing these solvents with this

spray gun.

Important: This gun may be used with

most common coating and finishing

materials. It is designed for use with mildly

corrosive and nonabrasive materials.

If used with other high corrosive or

abrasive materials, it must be expected

that frequent and thorough cleaning will

be required and the necessity for replace-

ment of parts will be increased.

INSTALLATION

1. Attach the air supply line to the air

inlet (26). An air transformer installed

as close as possible to the gun will

provide filtered and regulated air.

Note

When larger diameter air hoses

are used, it is advisable to use an

8' or 10' "whip end" or a smaller

diameter hose at the gun for

greater flexibility or movement.

2. Attach the suction feed cup or fluid

hose to the material inlet.

PREVENTIVE MAINTENANCE

To clean air cap and fluid tip, brush exterior

with a stiff bristle brush. If necessary

to clean cap holes, use a broom straw

or toothpick. Never use a wire or hard

instrument. This may scratch or burr

holes causing a distorted spray pattern.

To clean fluid passages, remove excess

material at source, then flush with a suit-

able solvent using a device such as the

SolventSaver™ (see Accessories). Wipe

gun exterior with a solvent dampened

cloth. Never completely immerse in

solvent as this is detrimental to the

lubricants and packings.

Note

When replacing the fluid tip or fluid

needle, replace

both at the same

time. Using worn parts can cause

fluid leakage. See Charts 1 and 2.

Also, replace the needle packing

at this time. Lightly lubricate the

threads of the fluid tip before

reassembling. Torque to 15-20 ft. lbs.

Do not overtighten the fluid tip.

To prevent damage to the fluid tip

(5) or fluid needle (11), be sure to

either 1) pull the trigger and hold

while tightening or loosening the

fluid tip or 2) remove fluid needle

adjusting screw (17) to relieve

spring pressure against needle

collar.
