2.1.2 Notes on procedure for disassemby/assemblyassembling work such as phase adjustment or mecha-
nism adjustment.
The disassembling procedure table (Table 2-4-1 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 ac-
tual 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.
