HOW TO USE SHEAR

Model 6603:

Firmly support and clamp the workpiece to ensure control. Place the side knives of the shear slightly on the edge of the top side of the workpiece to steady the tool. Squeeze the trigger switch and guide the shear into the work. The tool cuts freely with only slight pressure. Forcing the tool will not make it cut faster. Always use sharp cutters. A light coat of suitable cutting fluid applied along the line of cut will increase the cutter life.

You can produce a cut-out within the perimeter of the workpiece by drilling a 1/2" diameter starting hole and following the directions above.

Model 6605.

Firmly support and clamp the workpiece to ensure control. Position the workpiece with the hidden or back surface of the material facing up to reduce marring of the exposed side. To achieve

maximum cutting efficiency, hold the bottom of stationary blades parallel to and against the workpiece.
