against the end of the piston shaft.
AG900+S Module: See Figure 11. Install the new
needle assembly onto the piston/cartridge
assembly. Turn until the needle bottoms out
against the end of the piston shaft.

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
.
