1. Work Precautions
When conducting maintenance work, be careful to avoid injury caused by springs or the sharp
edges of sheet metal.
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 procedures presented in
the Technical Manual. In cases where, for example, it is necessary to disassemble 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 procedures 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.

damage screws and parts. Have all the tools necessary for the
work available.
