Proper spring pressure and dwell are set at the factory. However, adjustment may be
necessary from time to time. The factory settings are as follows:
Sharp Blade spring height - .750” Dwell - .015”
Dwell is measured while the knife blade assembly is fully compressed against the
sonic horn.
Spring height is measured when the knife blade assembly is in the “up” position.
To adjust the knife blade pressure, use the supplied 9/16” wrench (part # 571399), to
turn the Adjusting Nut clockwise/counter clockwise to achieve desired pressure. The
nut bracket will keep the spring nut from rotating and allow easy turning of the adjust
nut.
To adjust knife blade dwell, use the supplied 9/16” wrench to hold Adjusting Nut in
place. Use ½” wrench to loosen the Locking Nut. Turn the Spring Nut to move the
Adjusting Rod up/down for desired gap setting.
