(1) Open the front cover. Then pull out the
transfer/transport unit by turning its handle
clockwise.
(2) Remove 2 screws and open the IH cover-1
carefully to the front side.
(3) Remove 4 screws and then release 4 power
supply harnesses of the IH coil.
Notes:
1. Be sure that each of these harnesses is
connected to the proper position.
2. Use tightening torques of 1.2-2.0 N•m for
the 4 screws connecting these power
supply harnesses.
3. Since the IH board is a high-voltage
section, be sure to pull out the power
cable before starting maintenance or
checking. Especially do not touch the
IGBT when the power is ON since it is
generating high-voltage.
