Trigger & Needle Guard Readjustment Procedure
If you trigger the gun and notice that one needle is activating before
the other and not parallel, ne adjustment is needed.
1. Using a 5/64in. hex key adjust the Set Screw which is NOT making
gun pin contact when the gun is triggered. Turn the set screw until
both needles activate at the same time. Making the needle guard
parallel is very important, to prevent LAG-LEAD in the catalyst
& resin mix.
