JGHV SPRAY GUN WITH
TLC-576 OR TSC-591 CUP
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 D
all 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
D all 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 D from gun before placing gun
assembly in washer. Do not put regulator
or gauge in gun washer.
