TLC-576 OR TSC-591 CUP
READ THIS BEFORE YOU ATTACH THE AIR HOSE!
3. Place a small quantity of solvent in
the cup. Reconnect air supply to gun.
Spray solvent until clean.
Certain environmental legis-
lation prohibits spraying sol-
vents into the atmosphere.
Check local codes.
Air Supply Requirements:
• 18 SCFM at 10 PSIG air cap pressure
(33A air cap)*
• 22.5 SCFM at 10 PSIG air cap pressure
(#46MP air cap)*
• 26.0 SCFM at 10 PSIG air cap pressure
(#83MP air cap)*
• Minimum 5/16" inside dia. air hose
1. Turn A all the way.
2. Pull trigger and turn B
until the trigger touches the handle.
3. Turn Dall the way.
4. Fill cup with paint. Connect air hose.
Perform the following steps and prac-
tice on a piece of cardboard.
5. Adust air pressure to gun handle, cor-
responding with required baffle range:
JGHV-450-28 or 33-80=80 psi maximum
JGHV-450-28 or 33-50=50 psi maximum
JGHV-450-46-50=50 psi maximum
JGHV-450-83-65=65 psi maximum
These input pressures result in 10 psi
air cap pressure. Use only as much
atomizing air required to properly
atomize. Verify pressure at cap using
KK-5033-28, 33A 46MP or 83 MP air cap
test kit.
6. While triggering the gun, very slowly
turn D to increase fluid pressure.
7. If too much paint is being sprayed, turn
Dall the way and push down C
to remove all cup pressure. Repeat Step
No. 6 at lower pressure.
CLEANING GUIDE
Gun washers do not adequately clean HVLP
guns and cups. The solvent spray must be
directed at critical areas such as the check
valve and poppet. A small squeeze bottle
filled with solvent is useful for cleaning
these areas.
If a gun washer is used, be sure to remove
regulator Dfrom gun before placing gun
assembly in washer. Do not put regulator
or gauge in gun washer.
Cleaning Procedures
1. Disconnect spray gun from air supply.
2. Remove cup and empty paint, wipe lid
clean, fluid tube and inside of cup.
The paint cup is pressurized.
Press the poppet C to release
all cup pressure before open-
ing the cup.
*SCFM = Standard cubic feet per minute (air volume)

4. Disconnect spray gun from air sup-
ply. Remove cup and empty surplus
solvent, wipe clean with a lint free
dry cloth.
5. Remove check valve. Flush clean
solvent into the top, bottom and
side holes of the check valve.
6. Flush solvent into the poppet hole and
straight barbed fitting hole. Failure to
use clean solvent may result in a sticky
film accumulating on check valve ball
or seat surfaces. Sticking may then
occur.
7. Remove air cap and brush exterior
of cap and fluid tip with a soft bristle
brush and solvent.
8. Wipe exterior of gun and cup with a
solvent dampened cloth.
9. Dry all parts including gun air and
fluid passages and check valve using
a maximum of 15 PSIG compressed
air.
10. Inspect check valve to insure spring
and ball are properly oriented. Test by
depressing ball with poppet to make
sure ball isn't stuck and it returns
properly.
