CHAPTER 1. MAINTENANCE
2. Work Precautions
Inspection
If you discover any defects or problems during an inspection, fix the problems or if necessary take
steps such as replacing a part.
Removal
Check the problem area. At the same time, examine the cause of the problem and determine
whether the part needs to be removed or disassembled. Next proceed according to the proce-
dures presented in the Technical Manual. In cases where, for example, it is necessary to disas-
semble areas with large numbers of parts, parts which are similar to each other, or parts which are
the same on the left and right, sort the parts so that you do not mix them up during reassembly.
(1)
Carefully sort the removed parts.
(2) Distinguish between parts which are being replaced and those which will be reused.
(3) When replacing screws, etc., be sure to use the
specified sizes.
Assembly and Installation
Unless specified otherwise, perform the removal proce-
dures in reverse during assembly and installation. In
cases where protrusions or holes are provided to assist
in positioning parts, use them for accurate positioning
and securing.

Tools
Using tools other than those specified can lead to injury
or damage screws and parts. Have all the tools neces-
sary for the work available.
