REPLACING METHOD FOR MAIN PARTS REMOVE OF CORD REEL ASS’Y 1. Remove the 4 screws fixing the body. (Fig. 2.) 2. Remove the body from the panel ring. 3. Remove the cord reel from the body, and disconnect lead wire from the cord reel. 4. - Page 13 3. With the lid held with a handle, first release the latch button and open it to a normal degree, at which the lid first stops.(Fig. 4.) 4. Press the both sides of the lid assembly outward at the claws to release.
- Page 14 CAUTION When assembling, be sure not to catch the lead wires for the inner lid heater. As shown in Fig. 6, the lead wires of the lid heater are to be passed under the rib of the lid cover and passed above the hinge pin. After assembly, make sure not to have deformation of inner lid packing.
