I bought a Kramer Krane for my daughters for Christmas - figured something fun in these crazy times. It works, but I can’t get it to pick up any stuffed animals because the crane strength is weak. I’ve got the technical document (attached), opened it up, and believe I have found the POT that will adjust - but it doesn’t look like it turns. I haven’t tried with much pressure for fear of breaking it. Am I in the right spot for the adjustment and just need to try and turn it harder?
