(2) Minimal damage to studs permits easy processing
Because of the special cutters employed, few burrs are caused during cutting, and nuts can be attached to the
studs smoothly and easily. Deburring can be done easily and quickly by means of the provided trimmer.

(3) Lightweight
The length of a stud is basically determined by the various needs of the work site. If the ceiling is slanted, for
example, it is hard to determine appropriate lengths. In such a case, it is common to hang studs which are longer
than the required length, and mark and cut them off later. When mounting ducts, up to 20 studs can be cut at a
time at floor level (with a cut-off machine, for example). When mounting luminaiers, however, often only two studs
are cut in one spot. This means that the cut-off machine must be moved from one spot to another over a wide
area.
The Model CL 10SA is compact, lightweight, so it is easily transportable and particularly convenient for cutting off
hanged studs.
