Guide :Food Mixers : KSM90 Ultra Power Series Stand Mixer
Pops out of lock under a heavy load
When kneading bread or pizza dough at no more than Speed 2 setting, motor section "bucks" and soon unlocks itself.
This bucking has caused the thumb screw to unscrew allowing both it and the cap hub to fall into the mixer bowl during the mixing process. As a result, the plastic part of the thumb screw has cracked and no longer stays screwed in (I have it taped on with blue painter's tape in order to keep debris out of the attachment hole).
Is there something that I can tighten or adjust to remedy this problem? Can I get a replacement for the thumb screw?
Thanks in advance
