1. The MAX gripping force was measured at the midpoint of master jaw stroke in static condition.
2. Never exceed the gripping range; otherwise, the poor engagement between jaw tooth and scroll will cause breakage in jaw tooth, thus it will result in hazard by flying workpiece.
3. Take care of interference among jaws, machine and cutting tools, as op jaws stick out of the edge of chuck body when gripping big workpiece.
