Introduction

This section contains procedures required for parts replacement and adjustment.
How to Use the Replacement and Adjustment Section
For installation procedures, only NOTEs are described here since installation procedures are
the reverse of removal ones.
1. (Figure X) at the beginning of a procedure indicates that its detailed steps are shown in
the illustration. Numbers in the illustration indicate the sequence of the steps.
2. (REP X.X.X) at the end of a procedure indicates the replacement procedure to be referred
to.
3. Item numbers of replacement and adjustment procedures (i.e. REP/ADJ No.) correlate to
the PL No. in Section 5 Parts List. Therefore, an appropriate replacement or adjustment
procedure can easily be referred to a PL No. and vice versa. For example, the replace-
ment or adjustment procedure of Component PL 1.1 is REP 1.1.X or ADJ 1.1.X.
4. When replacement/adjustment procedures or title items vary by modification or model,
the modification number or the model is indicated at the beginning or the end of the
respective titles or procedures.
Example 1: REP X.X.X Main PWB [Models with 1V] indicates that the entire procedure
under this title applies to machines with Tag 1V.
Example 2: See Table 1.
