38. Install the catalyst tip over the spray tip.
Note
Use caution not to damage the O-rings on the front of the gun block.
39. Install the retainer to secure the catalyst tip and spray tip in place.
40. Spray a test pattern.
41. Make gelcoat pump pressure adjustments until a fairly uniform pattern is achieved with
slight horns on either side of the spray fan.
42. Slowly open the air-assist needle valve located on the side of the gun handle until a soft,
uniform pattern is achieved.
Internal Mix
43. Use a little red grease on the O-rings and threads of the spray tip, catalyst tip, and retainer.
44. Install the turbulent mixer into the mix chamber.
45. Insert the static mixer and spray tip onto the air assist housing and screw the air-assist onto
the gun mix housing.
Note
For longer turbulent mixer life, do not overtighten the air assist nozzle housing.
46. Attach the air-assist tube from the needle valve on the side of the gun handle to the air-assist
head.

Performing Daily Tasks
Daily Start Up – External Mix
1. Check all hoses for damage; replace as needed.
2. Check all material supplies and refill or replace as needed.
3. Open the recirculation valve on the catalyst manifold.
4. Open the main air inlet valve on the manifold.
5. Remove the pivot pin from the catalyst drive.
6. Manually pump the catalyst pump with the catalyst drive until you observe the stream
returning to the catalyst jug is air free.
7. Close the recirculation valve on the catalyst manifold.
8. Manually pump the catalyst pump with the salve arm drive, bringing the catalyst pressure to
operating pressure of about 100 psi.
9. Check the pump pressure; if adjustment is needed, press and hold the priming button while
slowly adjusting the air pressure.
