Congrats on your new arrival! There are lots of threads about grinding / sharpening (opposed to this specific topic on depth gauges) - most apply to any model of full sized, round grinder, and chain and might be a better place to attract input on general questions. Here is one of them for the similar 511A grinder (slightly different vise):

In general:
- take your time;
- take lots of light taps;
- dress your wheels frequently;
- start with some scrap chains and see what it takes to
intentionally overheat a cutter - then work back from there;
- 'play around' with the settings and see how they affect the cutter shape.
While your chain and cutter are both new, try 'fitting' the wheel to your new chain and working backwards to read the scales: does the vise read 30° in each direction (or maybe 29° Right and 31° Left)? Does a grinder head tilt of 60° match, or is 57.5° closer? etc. Once you start sharpening, it is up to you to decide what angles you want - but these decisions should be
intentional choices.

I profile my cutting edges first, so I know how much gullet I have to clear. Then I 'back off' the chain positioning stop / dog about 1/2 a turn, and lower the wheel depth about 1/2 a turn, and 'run' the gullets. This works for small amounts, and needs to be adjusted for gullets that have long been ignored. Again, you will develop methods that work for you.
