Replace the Piston/Cartridge Assembly

Disassembly

To disassemble your applicator to replace the piston/cartridge assembly, perform the

following procedure:

1. Heated applicators: disconnect and lock out input electrical power from the applicator.

NOTE: Do not remove the module from the regulator body or applicator adapter body

unless applicator location prohibits easy access.

NOTE: Standalone modules are mounted using threaded holes in the applicator body.

Remove screws before proceeding.

2. See Figure 16. If location requires the AG900+/AG900+S module to be removed from

the regulator or applicator body adapter to access components, do so by removing the

two socket head screws from the front of the module and pulling it free.

NOTE: Module must be pulled straight away

to avoid damage to locating dowel pins on

back face of module.
