Cutter bit (cont.)
Loose the 2 securing screws slightly so that the mount can be pivoted. Push the cutter down
so that the cutting edge will be in contact with the horn face. Pivot the mount slightly so
that the contacting area will be a line rather than a point. Tighten the securing screws.
Recheck the contacting area again so that the mount did not move during tightening.
After the cutter bit is replaced, the self calibration (described in the next section)
MUST
be
performed before operating the machine.
WARNING !
Failure to calibrate the cutter may cause damage to the horn face and/or cutter bit.
Ultrasonic component
All ultrasonic components are calibrated to match each other as the correct frequency is
critical to the proper machine operation. There are no user serviceable parts in the system
including the power board and the ultrasonic stack, horns, etc. All parts replacement should
be done by authorized technician or send back to the factory. Do not attempt to hammer,
dismantle or unscrew the parts with consulting H&H as the ultrasonic stack contains fragile
component that could be damaged easily.
