4.1
Disassembly/Assembly and Adjustment Initial Issue
4.1 Introduction
This section contains procedures required for parts disassembly, assembly, replacement and
adjustment in the field service.
4.1.1 How to Use the Disassembly/Assembly and Adjustment
1. For installation procedures, only NOTEs are described here since installation procedures
are the reverse of removal ones.
2. (Figure X) at the beginning of a procedure indicates that its detailed steps are shown in
illustration. Numbers in the illustration indicate the sequence of the steps.
3. (REP X.X.X) at the end of a procedure indicates the replacement procedure to be referred
to.
4. Item numbers of disassembly/assembly and adjustment procedures (i.e. REP/ADJ No.)
correlate to PL No. in Chapter 5 Parts List. Therefore, an appropriate replacement or
adjustment procedure can easily be referred to a PL No. or vice versa. E.g. The replace-
ment or adjustment procedure of Component PL 1.1 is REP 1.1.X or ADJ 1.1.X.
5. When replacement/adjustment procedures or title items vary by modification or model,
the modification number or the model are indicated at the beginning or the end of the
respective titles or procedures.
E.g. 1) REP X.X.X Main PWB [Models with 1V]
*Indicates that the entire procedure under this title applies to machines with Tag 1V.
E.g. 2)
6. Positions or directions of the machine and directions inside the machine used in the pro-
cedure are defined as listed below.
(1) Front: Front of the machine
(2) Right: Right-hand side when facing the front of the machine.
(3) Left: Left-hand side when facing the front of the machine.
(4) Rear: Rear when facing the front of the machine.
