wheel. This can lead to kickback,
other reactive forces or a shattered
composite cutting wheel, which
could result in severe or fatal
personal injury.
If necessary, leave small sections

that hold the part that is to be
separated in position. Break these
sections manually with a hammer or
other appropriate tool after making
the last cut.
If the outer diameter of the pipe or other
round, hollow body is smaller than the
maximum cutting depth of the wheel:
Make one cut from the top to the
N
bottom of the pipe.
If the outer diameter of the pipe or other
round, hollow body is greater than the
maximum cutting depth of the wheel:
Plan first, then cut. The sequence shown
in this manual is illustrative and not
meant to substitute for the judgment of
the experienced workmen with actual
knowledge of on-site conditions.
However, the last cut must always be
made in such a way that the cutting
wheel cannot become pinched, bound
or clamped and so that the operator, co-
workers and bystanders are not at risk of
being injured by a falling part that has
been cut off or out, by cutting debris or
sparks. Generally, this should be in the

top portion of the pipe using the bottom
section of the cutting wheel with the
guard covering the top of the wheel.
If the pipe is in-ground or otherwise
cannot be rolled:
Support the pipe and chock it if

necessary to prevent it from rolling,
moving or vibrating.
Rotate the guard to the forward

To reduce the risk of pinching or

binding and kickback, start cutting in
the lower section of the pipe.

being careful not to tilt or twist the
wheel, and continue the cut down to
the center of the bottom half of the

Insert the abrasive cutting wheel at

full throttle into the existing cut,
being careful not to tilt or twist the
wheel, and continue the cut down to
the center of the bottom half of the
pipe. Make sure that the cut at the
bottom is complete and joins the
first cut made to the bottom of the
pipe. Illustration D. If the cuts fail to
meet, never attempt to make them
meet by twisting the machine or
wheel, bending the wheel or
attempting to change direction in
the cut. Start a new cut that will
