The cylinders are single-acting with spring return. An angled head makes access easier. Sets and separate replacement chisels are listed in the parts directory. The nut material, strength class and accessible space must be checked before selection.
Select according to the actual across-flats size. Published thread-size assignments for the largest model are inconsistent and are therefore not used as a selection rule here.
