Replacing the Top Knife Blade
Upper blade wear is caused by the abrasion from the ultrasonic vibration
when the horn face and the edge of the blade are in contact. There are
four major adjustments that control the life of the upper blade. The first is
a properly tuned power supply. Second is the blade parallel the horn
face. Third is the amount of pressure between the blade and the horn
(factory setting .750”). Fourth is the dwell time between the blade edge
and the horn face after the cut has been made (factory setting .015”).
The following is a guide to properly replace the upper knife blade.
