The Drive motor shutting off is the result of a mechanical bind or an electrical problem.
The first thing to check is to make certain the folder is setting level and that the fold pans are not rubbing the fold rolls.
If the above items are okay I would remove the non-operator side guard. Then remove the belt from the motor. Run the motor to see if it still shuts off. If the motor does shut off then you know it is a problem with the motor or switch and you need to call 1-800-543-6107 and ask for technical support.
If the motor does not shut off then you have a mechanical bind. In the older 714's (serial numbers beginning with 82 thru 90) the bearings on the ends of the fold rollers need to be lubricated periodically with a lightweight oil. Also the gears that drive the feed table and the stacker also need to be lubricated with lightweight oil. These gears are located on the inside of the non-operator side frames between the feed table and the stacker.
Another item that could be causing the problem would be the slitter shaft thumb screw that tightens into the frame. This screw should only be into the frame a couple of threads. If it is tight it could cause a bind.
If these items do not resolve the problem please contact our Technical Support group at 1-800-543-6107
