Service Notes will be published in Support Update. They are printed in reduced size for placing
in this binder. Remove them from the Support Update, punch them and pi ace them behind
this page.
How to Punch the Service Notes
A
problem arises in that six-hole punches are not widely available. The Service Notes may
either be punched with a hand punch, or a three-hole punch may be adjusted to punch the
Handbook pattern.
To modify a three-hole punch to punch the Handbook hole pattern, follow these directions:
1. Most punches have an inch scale to position the individual punches. This scale has zero in
the middle, and increases to the left and right. Move the individual punches to the 1
7 /8,
2% and 3% positions. The punches can be on either the left or the right (or any combina-
tion) as long as each number has a punch on it.
2. Center the page to be punched on the scale. That is, put the left edge on the same
number on the left scale as the right edge is on the right scale. For an 8112 inch page this
will be 41f4.
3. Punch the page, then turn it over, center it and punch it a second time.
