Hi. Keeping a folder of PDFs for him is a smart move, and skipping the spammy sites is the trick. Have a look at ManualMachine https://manualmachine.com/ – it’s a large, well-organized archive of user guides and service manuals for all sorts of devices and brands, so you can search his gadgets by model and pull up the documentation in one place. The collection is enormous, millions of files across tens of thousands of brands, including plenty of older products. It’s far cleaner than the random spammy results you get elsewhere. Search each of his gadgets there, grab the manuals, and you’ll have that single reference folder sorted so the calls slow down.
