I've got a OF1010 with a loose handle or "knob". The one used to activate or deactivate the plunge mechanism. I pulled the cap off and see no clear way to tighten its fit to the bolt. Any fix for this?
i have the of 1400 not sure if its the same but mine became loose over time i just tightened the nut at the back of the knob (between the knob and the machine) its fine now
