SERVICE BULLETIN

SB-2-616-B

IMPORTANT: Before using this equipment, read all safety

precautions on page 2 and instructions. Keep for future use.

DESCRIPTION

The FLG-693 and FLG-694 are light weight, general purpose suction

feed spray guns for both conventional and HVLP spraying applica-

tions suitable for use with a wide variety of common coating

materials. These models include the TGC-545 suction cup. The

FLG-692 is a pressure feed HVLP spray gun.

Halogenated hydrocarbon solvents - for example; 1, 1, 1-

trichloroethane and methylene chloride - can chemically

react with the aluminum in this gun and cause an explo-

sion hazard. Read the label or data sheet for the material

you intend to spray. Do not use spray materials contain-

ing 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 non-abrasive materials. If used with other high corrosive or

abrasive materials, it must be expected that frequent and thor-

ough cleaning will be required and the necessity for replacement

of parts will be increased.

OPERATION

Strain material thru 60 or 90 mesh screen.

Model FLG-693:

The No. 1 (conventional) air cap requires an air supply at the gun

inlet of approximately 45 psi, measured with the trigger pulled

and can be operated from a 3 H.P. compressor.

HVLP Models FLG-692 and FLG-694:

The No. 3 (HVLP) air cap requires an air supply at the gun inlet of

23 psi max., measured with the trigger pulled.

This gun was manufactured to provide maximum transfer efficiency

by limiting air cap pressure to 10 psi (complies with rules issued by

SCAQMD and other air quality authorities).

This gun will produce approximately 10 psi cap pressure at 23 psi

inlet pressure, as measured at the gun inlet. An air cap test kit (see

ACCESSORIES) should be used to insure 10 psi cap pressure is not

exceeded.

Adjust fluid pressure to deliver the desired paint volume. Adjust air

pressure and fluid flow to provide a uniform dispersion of atomized

paint throughout the pattern. Keep air pressure as low as possible

to minimize bounce - back and overspray. Excessive air pressure

will result in split patterns. Low air pressure will result in heavy

centered patterns and poor atomization. Excessive fluid flow will

result in heavy center spray patterns. Inadequate fluid flows may

cause the pattern to split. See Spray Gun Guide, SB-2-001, which is

available upon request, for details concerning set up of spray guns.

To hang the spray gun when not using, refer to the "Accessories"

page 8 (192219 or GH-407).

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 if

possible. If a wire or hard instrument is used, extreme care must

be used to prevent scratching or burring of the holes which will

cause a distorted spray pattern.

To clean fluid passages, remove excess material at source, then

flush with a suitable solvent. 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.

To prevent damage to the fluid tip (3) 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 knob

(13) to relieve spring pressure against needle collar.

Spray Gun Lubrication

Daily, apply a drop of SSL-10 spray gun lube at trigger bearing stud

(21) and the stem of the air valve (14). The shank of the fluid needle

(11) where it enters the packing nut (24) should also be oiled. The fluid

needle packing (23) should be kept soft and pliable by periodic

lubrication. Make sure the baffle (6) and retaining ring (1) threads are

clean and free of foreign matter. Before assembling retaining ring to

baffle, clean the threads thoroughly, then add two drops of SSL-10

spray gun lube to threads. The fluid needle spring (12) and air valve

spring (15) should be coated with a very light grease, making sure

that any excess grease will not clog the air passages. For best results,

lubricate the points indicated, daily.

DESCRIPTION - MODEL TGC-545 CUP

This one quart capacity drip free suction cup has a unique, two

position valve which permits selection of either a drip free spraying

mode or a conventional open vent mode.

In the drip free position, air is directed through the vent in the lid to

a channel beneath the lid gasket before entering the cup at the valve.

This allows the cup to be tilted when full without dripping paint

through the vent.

The open position isolates the channel and opens a direct vent into

the cup.
