While rotating the Headstock, visually determine the point on the surface where Tool
Bit A comes closest to the pipe.
Rotate the Feed Sprocket until Tool Bit A makes contact with the pipe.
Back the Tool Holder away from the pipe about 1/4 of a revolution, [approximately
.008” (.20 mm)].
Each full revolution of the Feed Sprocket moves the Tool Bit .031” (.8 mm) toward or
from the pipe.
Continue to rotate the Headstock through 360 O slowly, in order to verify that the
position of Tool Bit A allows .006” (.2 mm) minimum clearance between Tool Bit A
and the pipe surface at the closest point.
Readjust Tool Bit A if necessary.
Mark the pipe surface to define Tool Bit A’s closest approach to the pipe.
Continue to rotate the Headstock slowly.
Position Tool Bits B and C directly over the mark that you made to define the closest
approach of Tool Bit A to the pipe.
Rotate the Feed Sprocket until Tool Bits B and C make contact with the pipe surface.
