Knife Pressure
This new design comes with factory set knife pressure. The following diagram
shows the factory settings for pressure with a new top blade. Should the unit
stop cutting, the knife blade should be leveled first, and if unsuccessful, add
pressure with the “Adjusting Knife Spring Pressure” instructions above.
A means to adjust this pressure is built into the knife linkage. To make this
adjustment, first the .015” gap must be set - followed by the .750” gap.
To set the .015” gap, jog the machine until the knife blade is in its full down
position with no fabric under the blade. Loosen the LOCK KNOB and turn the
ADJUSTMENT NUT until the gap is at .015”. Retighten the LOCK KNOB.
To set the .750” gap, jog the machine until the knife blade is in its full down
position with no fabric under the blade. Loosen the screw on the ADJUSTING
NUT; turn the ADJUSTMENT NUT until the gap is .750”. Tighten the
setscrew.

START & OPERATION
Replacing the Top Blade
Turn the Ultrasonic power supply switch off.
Note: The knife button and start button combination will cycle the blade ½
revolution - from no pressure to full pressure.
Because the knife blade will eventually wear from abrasion caused by ultrasonic
vibration when the horn face and the knife blade are in contact, the knife blade
will need to be replaced periodically.
To replace the knife blade, remove the knife blade guard. The knife is attached
to a self-leveling mount with a leveling pin. Loosen and remove the (2) knife
screws and remove the blade from the leveling pin. Replace the new knife blade.
Thread the (2) knife screws into the knife mount but do not tighten. The blade
must be leveled each time it is replaced. See below for knife blade leveling
procedure.
When removing the knife blade, the blade may seem tightly mounted to the knife
mount pin. Pull blade off of mount (leveling) pin by pulling from the top of the
blade.
Knife Blade leveling
Jog the knife with the TEST/START buttons until the blade is in full contact
with the horn. Tighten the two clamp screws in small equal increments until
they are very tight. Loose screws will shorten blade and horn life. (A loose
screw may cause the blade to make a noise during the cut.)
