If the pipe end is not square to the pipe axis, the tool bit will contact only a
small segment of the pipe during each revolution.
To avoid tool bit damage, the feed rate should be very slow until the tool bit(s) is in
contact with the pipe continually during at least one full revolution.
Continue rotating the feed handle clockwise until the end of the pipe is completely
machined.
Discontinue feed and allow the head to rotate 1 to 3 revolutions to improve finish of
the prep surface.
Release the air motor trigger to stop the head rotation.
Rotate the feed handle counterclockwise to separate the tool bit(s) from the pipe.
Rotate the feed handle counterclockwise until the tool bit to pipe clearance is 1/8” (3
mm).
Loosen the draw nut on the mandrel to release the mandrel from the pipe.
The mandrel assembly may be left in the BOILERMASTER™ and installed as a
complete assembly.
