DeVilbiss TLC-576 Reference manual

INSTALLATION
1. Position yoke at right angles to the gun
body with the cam (3) towards the
front of the gun.
2. Fasten lid assembly (11) to fluid con-
nector on the gun and tighten nut with
wrench.
3. Connect the air supply tube from regu-
lator to the fitting (8) on the lid.
OPERATION
Risk of injury. Cup is under pres-
sure during operation. Turn off or
disconnect air supply to spray gun
and paint cup before attaching or
removing the cup and cup lid and
before filling or cleaning. Turn the
cup regulator knob counterclock-
wise to shut off air to the paint cup.
Push down on the check valve pop-
pet stem (6) to relieve the cup pres-
sure.
Risk of injury or equipment dam-
age. Air pressure to the cup must
never exceed 20 psi (1.4 bar).
1. Mix, prepare and strain the material.
Remove cup (12) by moving the cam
lever counter-clockwise, fill cup. Do
not overfill.
Note
Only use a wooden or plastic paddle
or mixer for mixing material in the
Teflon® cup (TLC-401). A metal
paddle or mixer can scratch the
teflon lining.
IMPORTANT:
Read and follow all instructions and
SAFETY PRECAUTIONS before using this
equipment. Retain for future reference.

TLC-576 & TSC-591 HVLP LOW PRESSURE ONE QUART CUP
DESCRIPTION
These cups have a 1 quart capacity, for
pressure feed use with cup pressure regu-
lation. The TLC-576 Teflon® lined cup is
suitable for use with most common coat-
ing materials, where small amounts of
material or many color changes are re-
quired.
The TSC-591 is a high quality, stainless
steel cup designed for use with corrosive
type materials such as waterbornes. It is
also suitable for use with finishes contain-
ing halogenated hydrocarbon solvents.
Both cups are used with KK-4980 air regu-
lator kit (order separately).
Maximim working pressure: 20 psi (1.4
bar), connecting thread 3/8" NPS.
The Teflon cup check valve will prevent
the cup from losing pressure. The check
valve also prevents paint from backing up
into the air tube if the cup is tilted. The
poppet stem in the cup lid allows the
painter to manually relieve the cup pres-
sure.
2. Replace cup (12), engage pins into yoke
slots (make sure both pins are fully
engaged in both slots prior to tighten-
ing) and tighten by moving cam lever
(3) clockwise. Do not lubricate cam.
This can cause it to loosen.
3. Connect air supply to gun. Make sure
gun inlet pressure and cup pressure do
not exceed maximum limits.
4. Before refilling or emptying the con-
tents of the cup, depressurize the cup
by pushing down on the check valve
poppet stem (6) to relieve pressure
from the cup. If the check valve has
become wet it is normal for a small
amount of paint mist to be discharged
from stem hole.
Note
Horizontal spraying with a full cup
could allow paint to contact the
check valve. This could affect the
operation. Check valve (10) should
be cleaned after each use.
MAINTENANCE
Lid Repair/Replacement
1. To replace a damaged part, use a 5/16
inch Allen wrench to loosen and re-
move adapter (1). Nut (2), yoke and
cam (3), lid and tube assembly are now
loose for replacement.
2. Replace damaged parts on the lid and
tube assembly.
Note
To prevent leakage when reinstall-
ing adapter (1), apply sealant (Loc-
tite #262) to the first two full threads.
3. Insert threaded end of the adapter (1)
into open end of nut (2).
4. Install adapter and nut in top of lid and
tube assembly. Use a 5/16-inch Allen
wrench to tighten firmly (10-12 Ft. Lbs.).

Safeguards
Adequate exhaust must be provided to keep air free of
accumulations of flammable vapors
Smoking must never be allowed in the spray area.
Fire extinguishing equipment must be present in the spray
area.
Wear eye protection.
Follow the requirements of the Material Safety Data Sheet
supplied by your coating material manufacturer.
Adequate exhaust must be provided to keep the air free of
accumulations of toxic materials.
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 must be as prescribed by an industrial hygienst
or safety expert, and be NIOSH approved.
Read the label or data sheet for the material you intend
to spray.
Do not use any type of spray coating material containing
these solvents.
Do not use these solvents for equipment cleaning or
flushing.
If in doubt as to whether a material is compatible – contact
your material supplier.
Note
Information that you should pay spe-
cial attention to.
Cause
Solvent and coatings can be highly flam-
mable or combustible, especially when
sprayed.
During cleaning and flushing, solvents
can be forcefully expelled from fluid
and air passages. Some solvents can
cause eye injury.
Certain materials may be harmful if
inhaled, or if there is contact with the
skin.
TSC-591 is stainless steel and can be
used with Halogenated Hydrocarbons.
TLC-576 is alumimum. The solvent
1, 1, 1- Trichloroethane and Methylene
Chloride (sometimes called methyl
chloride) can chemically react with the
aluminum used in most spray equip-
ment, and this cup, to produce an ex-
plosion hazard.
The following hazards may occur
during the normal use of this equip-
ment. Please read the following
chart.

to prevent damage to equipment, or
how to avoid a situation that might
cause minor injury.

Do not use abrasives such as a wire
brush or steel wool to clean the
inside of the Teflon lined cup. Dam-
age to the Tefon surface could re-
sult.
CLEANING
1. Disconnect spray gun from air supply.
2. Remove cup and empty paint, wipe
clean lid, fluid tube and inside cup.
3. Place a small quantity of solvent in the
cup. Replace and connect air supply to
gun. Spray solvent until clean.
4. Disconnect spray gun from air supply.
Remove cup and empty surplus sol-
vent, wipe clean with a lint free dry
cloth.
5. Spray solvent into the bottom and side
holes of the check valve. Do not direct
air pressure higher than 15 psi through
or at the check valve. This may dam-
age the valve. The check valve can be
removed for cleaning if needed. It
cannot be disassembled. Allowing
paint to dry on the ball or seat surfaces
may cause the check valve not to func-
tion properly.
6. Spray solvent into the poppet stem
hole. To prevent sticking, it must be
cleaned after each use.
Note
The cam and mating surfaces on
the lid and yoke normally don't
require removal for cleaning. Spray-
ing some materials containing
Teflon® or similar materials can
necessitate more frequent clean-
ing and possible disassembly of
the cam. The overspray containing
Teflon® can build up on the cam
and mating surfaces causing a con-
dition where the cam may loosen
during use.
7. Clean cam and mating surface on lid
with a solvent soaked Scotch™ pad
and blow dry. If cam loosening per-
sists, removal of the yoke and cam will
be required for more thorough clean-
ing of these parts. Again, use a sol-
vent soaked Scotch™ pad for this
purpose. Reassemble lid.

IMMERSION
Since all materials in the cup are highly solvent resistant, the cup
assembly may be immersed for cleaning. Immersion should not
exceed 24 hours. The use of paint strippers should be avoided,
because strippers will affect the aluminum as well as other non-
metallic components. If the lid gasket has become swollen from
prolonged exposure to solvents, it will return to its original size
without loss of properties when allowed to dry
