Really nice job. Covers the assembly really well.
Here's a few things that came to mind:
pg 2. - pre-loaded tanks and coils. What are the tanks? Is that a separate accessory for loading herbs, or is it the tank the coils go in? What is it? There was some mention of loading a tank that sounded like it was a different thing. If it's new I want one!
Would like to see more on usage beyond what's on page 14... more on loading (people often seem to think the funnel is involved from standard cart use) and proper draw technique, avoiding leaks, storing on side, cleaning the rod... practical use tips. Also the heading on page 14 is "assembly instructions", but the page content is more about usage?
White rod vs. black rod use and battery configs.
Differences between sr-71 and 74. I know this is for the 71, but people should know about using 74 rods and which parts are interchangeable or not.
What tops work with SR-71 and what does not. HVD heads, etc.
What extracts work and don't work well with the 71... runny liquids, water/ice extracts, etc. Not sure how generic the language has to be to mention concentrates.
Page 15 (Troubleshooting). At the first step I might have mentioned the AW IMRs (what there's no plug for the Core?). I know it mentions AW's elsewhere, but I originally had trouble with the Herc that came down to not using AW batteries. The other step I run into is wispy vapor caused by needing to reload.
A section on how to reclaim would be good.
Using loose leaf and oils together?
Really through manual! Should help people master their Hercs.
Edit: unrelated feedback. I've always wanted to see a PDF that's a brochure of the line of w9 tech. A page on each major vape or accessory, so a person can see the range of possibilities in one viewing.
