SECTION 2 MECHANISM ADJUSTMENT
2.1 PRELIMINARY REMARKS ON ADJUSTMENT AND REPAIR 2.1.1 Precautions 1. When fastening parts, pay careful attention to the tightening torque of each screw. Unless otherwise specified, tighten a screw with the torque of 0.039 N·m (0.4 kgf·cm). 2. Be sure to disconnect the set from the power supply before fastening and soldering parts. 3. When disconnecting/connecting wires, be careful not to get them and their connectors damaged. (Refer to the Section 1.) 4. When replacing parts, be very careful neither to damage other parts nor to fit wrong parts by mistake. 2.1.2 Necessary jigs 1

2.1.3 Notes on procedure for disassemby/assembly The disassembling procedure table (Table 2-2-2 on page 2-5, a part of the table is shown below for reference) shows the procedure to disassemble/reassemble mechanism parts. Carefully read the following explanation before starting actual disassembling/reassembling work. The item numbers (circled numbers) in the following explanation correspond to those appearing under respective columns of the table. (1) Circled numbers appearing in this column indicate the order to remove parts. When reassembling, follow these numbers in the reverse order. Circled numbers in this column correspond to those appearing in drawings of this section. (2) This column shows part names corresponding to circled numbers in the left column.

(3) The symbol (T or B) appearing in this column shows the side which the objective part is mounted on. T = the upper side, B = the lower side (4) Symbols appearing in this column indicate drawing numbers. (5) This column indicates parts and points such as screws, washers, springs, and others to be removed/fitted for disassembling/reassembling the mechanism. Besides such the parts, this column occasionally indicates working points. P= W= S= *= etc. Example Spring Washer Screw Lock (L), soldering (SD), shield, connector (CN),
