CHAPTER 1: MAINTENANCE
3. 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.

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