Gun Adjustment &
St art up
Gun Adjustment and Start Up
1. Make sure trigger and trigger bar are not worn, loose or damaged before
adjusting gun or needle guides.
2. Adjust the Resin Needle Guide and Jam Nut so they will open just before the
Catalyst Needle, never catalyst first. How much you open the resin needle
before you open the catalyst needle will depend on the resin viscosity and may
have to be changed as the resin temperature changes. See the Testing and
Adjusting Manual (12016-2) for testing your gun.
3. Test the gun by putting 100psi of air to the catalyst and resin fittings and putting
the gun in a tub of water.
