You need foams made specifically for your speaker. I prefer kits that also include shims and dust caps.Kits with white glue are MUCH easier to work with than ones with solvent-based glue.

Here's the manual

http://www.calculated.com/ugfiles/UG34153415-KITE-F.pdf

and page 19 shows you how to do it with the shift key

Under these circumstances, the best suggestion I can make is to use Google translate or one of the other translation sites and translate as much as you can piece by piece until you have translated and printed out that entire manual. That's a lot of material and it will take a while. I would start with the basic stuff first then get additional translations as she needs them. Good luck!!!
