Procedure
To set up a mold release gun, do the following:
1.
Model L60M19 Mold Release Gun is supplied
with Part No. 24N748 Nozzle, 24N727 Air Cap,
and a spray tip of choice. If you require a different
size spray tip, see
(Model L60M19 MRG Gun Only), page 102
, or
consult with your Graco distributor. To install
the tip, see
Air Cap, Spray Tip, and Nozzle
Replacement (Model L60M19), page 60
.
2.
Follow steps 2–10 in the
3.
The fluid output and pattern width depend on the
size of the spray tip, the fluid viscosity, and the
fluid pressure. Use the
(Model L60M19 MRG Gun Only), page 102
, as a
guide for selecting the appropriate spray tip for
your application.
4.
Align the spray tip tab with the groove in the air
cap. Install the tip.
5.
Install the air cap and retaining ring. Orientate
the air cap and tighten the retaining ring securely.
6.
Close the atomizing air adjustment valve (G) and
the fan air adjustment valve (F).
7.
Check that the ES On-Off switch is OFF (O).
8.
Start the pump. Set the fluid regulator to 400 psi
(2.8 MPa, 28 bar).
9.
Spray a test pattern. Examine the particle size in
the center of the pattern (tails will be removed
in step 21). Increase the pressure in small
increments. Spray another pattern. Compare
particle size. Continue increasing pressure until
the particle size remains constant. Do not exceed
3000 psi (21 MPa, 210 bar).
10. Turn ON (I) the ES On-Off switch.
11. Check that the ES indicator (K) [Hz indicator on
Smart guns] is lit. See the following table.

Green
When spraying, the indicator
should remain green, indicating
sufficient air pressure to the
alternator turbine.
Amber
If the indicator changes to amber
after one second, the air pressure
is too low. Increase air pressure
until the indicator is green.
Red
If the indicator changes to red
after one second, the air pressure
is too high. Decrease air pressure
until the indicator is green. To
maintain a higher application air
pressure, install ES On/Off Valve
Restrictor Kit 26A294. Adjust the
pressure as needed to ensure the
indicator remains green.
