DISASSEMBLY/ASSEMBLY Overview 61
4.1  Overview
This section describes procedures for disassembling the main components of the 
product. Unless otherwise specified, disassembled units or components can be 
reassembled by reversing the disassembly procedure.
Procedures which, if not strictly observed, could result in personal injury are described 
under the heading “WARNING”.
“CAUTION” signals a precaution which, if ignored, could result in damage to equipment.
Important tips for procedures are described under the heading “CHECK POINT”.
If the assembly procedure is different from the reversed disassembly procedure, the 
correct procedure is described under the heading “REASSEMBLY”.
Any adjustments required after reassembly of components or parts are described under 
the heading “ADJUSTMENT REQUIRED”.
When you have to remove any components or parts that are not described in this 
chapter, refer to the exploded diagrams in the appendix.

 Since a prototype was used to illustrate these disassembly and 
reassembly procedures, the appearance of some parts may 
differ from those on actual product. The procedures 
themselves, however, are accurate for the retail model. 
 When using compressed air products; such as air duster, for 
cleaning during repair and maintenance, the use of such 
products containing flammable gas is prohibited.
