MARKETING OBJECTIVE The Model CM 4ST is the 4” cutter version of the low-end ST series model based on the CM 4SB. Overload strength is increased by adopting a powerful motor with maximum output of 1,950 W, while a rubber cover over the switch trigger section and lock button prevents the entry of dust, thus improving durability.

• Single-operation cutting must be restricted to cutting depths of 20 mm or less, at slow feed speed. Cutting at deeper than 20 mm must be done in two or three separate cutting operations. Attempting single- operation cutting at deeper than 20 mm will shorten the service life of the diamond wheel, and could cause motor burnout.
