Gun Setup
Mold Release Release Gun Gun Setup
Mold Mold Release Gun
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, follow the steps in
Spray Tip Selection Chart (Model L60M19
MRG Gun Only), page
your Graco distributor. To install the tip, see
Air Cap, Spray Tip, and Nozzle Replacement
(Model L60M19), page
2. Follow steps 2–10 in the
Gun Setup Procedure, page
3. Use the Spray Tip Selection Chart (Model
L60M19 MRG Gun Only), page
for selecting the appropriate spray tip for your
application. The fluid output and pattern width
depend on the size of the spray tip, the fluid
viscosity, and the fluid pressure.
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.

Color Color
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.
