...I'd be able to read the instructions on my new Shinto Saw Rasp. But I'm not.
Can anyone help out with this? Some of it is obvious from the drawings, but there are still questions. I'm asking here instead of on some Japanese language-type forum (if such a thing exists) because my prior experience tells me that this probably requires someone with woodworking knowledge, not just language knowledge. (I've had engineering drawings from Finland, and when I asked the software guy in my company who was from Finland, he had no idea because he didn't know the jargon.)
So, the instructions are on the back of the package. Here's the first pic from the top end.

First there's what is probably a list of features. But below that are some cautions, which would be good to know.
Next pic down:

In the first illustration, A and B orientations and actions are pretty obvious. But what meaning are they trying to get across in C and D?
The second illustration is obvious, pretty much the same as A and B above it. Don't attack end grain!
Next pic down has three areas:

First illustration: I'm thinking this means, " If you want to trim off the end of a board, first bevel it back to your trim line, then remove the remainder with a perpendicular cut." The pic suggests it might be referring to plywood specifically.
Second illustration: OK to go cross grain? Maybe?
Third illustration: Don't know. The first action seems prohibited by a previous instruction, but this time there's no X.
Last pic:

The illustration is pretty clear - to thin down a board, work similarly to the end trim / plywood instruction. Take bevels from two sides, and then go flat to the line.
Below the heavy horizontal bar is text that could be useful. Odd that it ends in what might be an ellipsis...
So, has anyone got a clue?
