This manual contains important information that ALL users should knowand understand BEFORE using the equipment. This
information relates to USERSAFETY
and PREVENTING EQUIPMENTPROBLEMS. To helpyou recognize this information.
we use the following termstodrawyourattentiontocertain equipment labelsand portionsofthis manual. Pay special attention
to any label or information that is highlighted by one of these terms:
WARNING I
Important information to alert you to a situation that
might cause serious injury if instructions are not fol-
lowed.
Note
Important information that tells how to preventdamage
to equipment, or how to avoid a situation that might
cause minor injury.
Information that you should pay special attention to.
AREA
Tells where hazards
WARNING I
The following hazards may occur during the normal use of this equipment.
Please read
the following chart.
HAZARD
Tells what the hazard is.
Solvent and coatings can be
highly flammable or combus-
tible, especially
when sprayed.
During cleaning
and flushing,
solvents can
be forcefully ex-
pelled from fluid and air pas-
sages. Some solvents can
cause eye injury.
The solvent
1, 1, 1- Trichlo-
roethane
and Methylene
Chloride (sometimes called
methyl chloride) can chemi-
cally react with the aluminum
used
in most spray equip-
ment, and these cups,
to pro-
duce
an explosion hazard.
Certain materials may be
harmful
if inhaled, or if there is
contact with the skin.
SAFEGUARD
Tells how to avoid the hazard.
Do notspray nearopen flames, pilot lights in stoves or
heaters, or other heat sources.
2. Adequateventilation mustalways be provided. Indus-
trial applications must comply with OSHA require-
ments.
Wear eye protection.
1. Read the label or data sheet for the material you
intend to spray.
2.
Do not use any typeofspraycoating material contain-
ing these solvents.
3. Do not use these solvents for equipment cleaning or
flushing.
4. It in doubt as to whether a material is compatible-
contact your material supplier.
1. Follow the requirements of the Material Safety Data
Sheet supplied by your coating material manufac-
turer.
2. Adequate exhaust must be provided to keep the air
free of accumulations of toxic materials.
3. Use a mask or respirator whenever there is a chance
of inhaling sprayed materials. The mask must be
compatible with the material being sprayed and its
concentration. Equipment used must be as pre~
scribedby an industrial hygienistorsafety expert, and
be NIOSH approved.

DESCRIPTION
The TGC-500-2 cup is used in applications where
agitation ofmaterial in the sprayguncup is required
to
prevent the settling of pigments and solids inthe paint
during application.
An air turbine mixing blade lifts
pigments and solids
from the bottom of the cup and
keeps it in suspension.
An airregulating valveontheturbineairline regulates
the speed
of the turbine to control the mixing action.
An air adjusting valve is also supplied at the
gun air
inlet
to control spray gun nozzle atomization.
INSTALLATION
Attach fluid connector(25, Figure 1) to spray gunfluid
inlet Make sure tube is attached to the gun with the
tube bend
out and awayfromthegun to allow room for
the cup.
Attach lower end of fluid connector
to fluid outlet on
cup housing (24).
Attach air adjusting valve to gun handle so that
the
valve airline fitting is onthe leftside of the gun handle.
Attach air line (9) to fittings. The assembled gun and
cup should appear as shown in Figure
1.
OPERATION
Risk of damage to shaft and seal. Do not oper-
ate the turbine without material in the cup.
Fill the cup with paint reduced to spray viscosity. The
full level is about i inch from the top, or just below the
area where the cup starts to bell out
Attach the cup tothe spray gun. Make sure turbine air
regulator valve (17) is turned off (all the way in) and
connect the air supply line to the gun.
Note
Spray guns with an agitator cup require higherair
line pressure. Spray gun nozzle air (atomization)
is regulated by the airadjusting valve (
i 2) instead
of air line pressure when using the cup.
With the
gun and cup in an upward position, open
turbine airvalve until the required amount of agitation
(mixing speed) is obtained. The mixing speed is
determined
by the amount of paint in the cup, paint
viscosity,
and airpressure used. Do not operate tur-
bine without material in the cup.
Approximately3 minutes is needed to completely mix
a full
cup of paint.
Check
for leaks from thecupandfittings by holdingthe
gun and
cup in a horizontal position w1th the mixeron.
If a leak occurs, tighten cup, or turbine air valve
packing slightly.
Spray in the normal manner. Should the mixing slow
down considerably,
or stopwhen the gun is triggered,
increase
the air line pressure at the main airregulator
for the gun.

Should the texture of the applied finish have too
muchorangepeel
or appear toodry,furtherreduc-
tion of paint maybe necessary. This is caused by
the total blending of the paint due to the mixing
action of the cup.
CLEANING
Afteruse, pour, asmallamountofpaintsolventintothe
cup. Attach the cup to the spray gun and turn the air
turbine
on (adjust turbine air regulator valve).
Shake the gun and cup up and down and trigger the
gun to clean all fluid passages.
Withthe airturbine
on, turn the gunupsidedown, turn
the air turbine
off. With the gun still turned over de-
presstheball andallowpaintsolventtorunthroughthe
vent passages.
To prevent excessive wear to shaft and
shaft sea!, clean cup as indicated below.
Wear to the seal can cause paint leakage.
Whencleaning the cup, it isvery importantto clean all
paintresiduefrom shaftseal and shaft area. Failure to
clean all paint residue will allow paintto harden. Once
hardened, the paint will cause abrasion and wear
betweenthe rotating shaft and seal.
If worn, paint can
leakfrom cup (thru airholeson thecoverassembly
(3)
if cup is tipped at an angle while spraying.

PAGE 4 SB-4-394-C
Remove cup from gun. Using aclean soft cloth damp-
ened with paintsolvent, wipe all exteriorsurfaces ofthe
cup and housing. Clean gasketarea of cup housing to
remove all paint from the gasket and cup lid edges.
After cleaning, inspect the shaft adjacent to washer
(18). Makesure all paint has been removed to prevent
hardening.
Attach cup loosely to the housing when not in use.
PARTS REPLACEMENT
Remove fluid connector (25) from cup.
Remove retaining ring (2). Pull shaft(19)out of bottom
of cup housing
(24) and remove impeller (20) from
shaft.
Remove the 3 screws
(1) from cover assembly. Re-
move turbine (4) from top ofhousing. Invert shaft (19)
and use it to press out the bushing (1 0) and seal (11)
through bottom of housing.
Insert new bushing (1 0) as shown. Insert seal (11)
(spring side towards turbine) through bottom of lid
assembly. Gently press into place using the turbine
end of the old shaft with a shaft washer (18)
in place.
Reinsert washer (18) on shaft (19) and insert into
housing (24). Reassemble impeller(20) ontobottomof
shaft. Insertturbine
(4) (be sure turbine blades are in
directionshown in Fig.
2) andcoverassembly(3) attop
and tighten with the 3 screws (1 ): Torque to 15 in. lbs.
Reassemble retaining ring (2).
GENERAL CLEANING
Remove turbine airregulator valve (17), bushing (16),
and gasket (15).
Soak all parts in paint solvent to loosen all dried paint
and residue from cup passages. Clean all parts using
a soft bristle
bnush and clean soft cloth.
After cleaning, dry all parts thoroughly.
Inspect all gaskets and parts for any signs of wear or
damage and replace if necessary.
PREVENTIVE MAINTENANCE
Frequently check agitator shaft area between shaft
(19) and shaftwasher(18). Remove anyaccumulated
paint to prevent premature wear. Disassemble and
clean the inside of the upper and lower bushings and
the seal with paint solvent.
The cup
is equipped with a spring-loaded ball check
dripless vent system. The vent opens automatically
when gun is triggered and closes when trigger
is
released. In order for it to work effectively, the vent
must
be kept clean at all times.
With paint solvent in the cup, loosentop vent cap and
turn spray gun and cup over allowing paint solvent to
flow through the vent passages. If the vent does not
clean satisfactorily, remove both vent caps (5), spring
(7), and ball
(6) and soak parts in paint solvent. Use
a pipe cleaner or similiar object soaked
in paint
solventtocleantheventpassagesinthecup housing.
