Set the distance by attaching the self-centring feet for
the pipe size to be laid (the 150 mm, six inch feet are
standard, all other sizes are optional) or by adjusting the
height of the Piper on the Trivet Mount Assembly.
The position of the laser beam relative to the centreline of
the pipe to be laid.
Set the line by aligning the laser beam with the next man-
