1. Preparing for Check, Adjustment and Parts Replacement of Mechanism Block
Before starting check, adjustment and parts replacement of mechanism block
1)
For the method of "how to remove the mechanism block" when performing check, adjustment and parts replacement of mechanism
block, refer to "How to Remove Mechanism Block" described in the mechanical adjustment manual of each model.
2)
When performing check, adjustment and parts replacement of mechanism block, use the Simple MSW jig in order to facilitate the above
operations at all times. For the selection of each [
] mode that is specified in this manual, refer to "Section 1-2. Simple MSW Jig
Operating Procedure" of this manual.
3)
Disassembling, re-assembling and adjustment of the mechanism block are performed using the [ULE] mode unless otherwise specified.
