Removing the keys
<Removing the keys>
To remove the keys, you will need two of the tools described below.
Before removing a black key, you must rst remove both white keys on either side of the black key.
White keys may be removed with the same procedures as removing black keys.
<Tool>
The tool used in the photos in this section was converted from a gardening ID tag. The size and shape
of an ID tag accord to the dimensions below.
<Note on shaping an ID tag>
The thickness of the tool must be within 1.2~1.3 mm.
If the tool is too thin, removing keys become difcult.
If the tool is too thick, it may damage the rib of the chassis.
