TO CLEAR A NAIL JAM:
1. It helps to tap the Driving Blade back to the retracted
position before trying to remove a jammed nail. The
spare Driving Blade works best for this.
2. Try to pull the jammed nail out of the gate with a pair
of long nose pliers. If this does not work remove the
four (4) cap screws holding the Foot, Gate and Nail
Channel Assembly together.
