Assembly
1. Install the needle assembly onto the new piston/cartridge
assembly. Turn until the needle nut bottoms out against
the end of the piston shaft shoulder.
NOTE: If the piston shaft is not fully seated inside the
needle assembly, the piston/cartridge assembly with the
needle assembly will not properly seat in the applicator
module and nozzle, resulting in adhesive leaking
.
2. AG900+ Module: See Figure 21. Install the new needle
assembly onto the piston/cartridge assembly. Turn until
the needle bottoms out against the end of the piston shaft.
Tighten jam nut.
AG900+S Module: See Figure 20. Install the new needle
assembly onto the piston/cartridge assembly. Turn until
the needle bottoms out against the end of the piston shaft.

3. Clean applicator module bore.
4. Apply o-ring lubricant to the module bore inside the applicator module body.
CAUTION! Apply o-ring lubricant to module body bore ONLY. Lubricating o-rings
directly or individual components causes back-up rings to become dislodged
when module is assembled.
5. Install piston/cartridge assembly into applicator module body. Carefully press on top of
the cartridge to properly engage cartridge o-rings into the module body bore.
NOTE: You will hear a small pop when the assembly seats in the module body.
