1.Reassemble the needle assemblies to the gun body. Lubricate the o-rings & use teflon tape on the threads.

seen between the gun block and the back side of the trigger and they both are exposed at the back of the gun block near the catalyst and resin needles.

3.Lock-tite both of the set screws, then assemble them to the needle guard using a 5/64in. hex key and make sure they are flush. Fine adjustment will be done after reassembly.
