1.4 Intended Use

The JT400 jointer is used to flatten and straighten rough lumber, 
boards, and other wood products before finishing. Face jointing 
removes bowing and twists in a board that is positioned flat on the 
machine table. Straight-lining or edge-jointing squares a board that 
is positioned on its edge on the machine table.

The machine has a 16" (405mm) cutting width, enhanced 
engineering designs, and superior build construction. It offers 
intelligent standard features like an interchangeable fold-away bridge 
guard, helical cutting system for quiet operation, and 96" (2440mm) 
cutting length.
