The graduated knob is the control the operator uses to adjust the cutting thickness on the FIA Boston Plus 350E slicer, turning it to move the slicing plate closer to or further from the blade.

• Graduated scale to set the cutting thickness repeatably
• Specific to the FIA Boston Plus 350E slicer

Replacement is needed when the graduated ring is worn or no longer readable, when the movement is too loose or too stiff and no longer holds the set position, or if the mounting seat on the adjustment pin is broken. An intact knob ensures consistent slice thickness during work.
