Basically hold the trigger down and pull the pump handle back. then bring it slowly forward until it fires.
Look at the spot where the gun fired. If it is over the size of a nickel 1/8 inch then you need to adjust it. Turn the allen head clockwise a half turn at a time until you get close then find the sweet spot.
The guy you talked to was Rod. If you have any other questions or issues please don't hesitate to call back.
