top portion of the pipe using the bottom

If the pipe is in-ground or otherwise
cannot be rolled:
Rotate the guard to the rear limit

stop.
A
To reduce the risk of pinching or
N
binding and kickback, start cutting in
the lower section of the pipe.
Illustration A.
B
Use the front and upper part of the
N
abrasive wheel for cutting the
opposite lower side. Make sure that
the cut at the bottom is complete.

C
Next, make a cut from the top half of
N
the pipe down, connecting with the
cut from the lower half.
Illustration C. Do not attempt to twist
or bend the machine or wheel to join
the two cuts.
D X
Make a cut in the marked area
N
shown above, leaving uncut the
section labeled "X" in the illustration.
Connect the cut with the cut in the
lower half. Do not attempt to twist or
bend the machine or wheel to join
the two cuts. To keep the pipe from
pinching, binding or clamping, do
not cut into the area labeled "X."
Illustration D.
Only make the final top cut once all
bottom and lateral cuts have been
completed and connect with one
another.
E
Always make the final separating
N
cut from the top (approx. 15 % of the
pipe circumference). Illustration E. If
the workpiece is properly
supported, it should not pinch when
the cut is completed. If there is any
residual pinching, however, it will be
at the bottom of the wheel, where it
may result in pull-away, but not in
kickback. Be alert for pull-away.
If the pipe can be rolled:
Use only the bottom of the abrasive
N
cutting wheel to make an initial
partial cut with the guard of the
machine pushed fully forward to the
limit stop, covering the top of the
wheel.
Roll the pipe, resecure and support
N
it. Make another partial cut using the
bottom of the wheel and the guard
covering the top of the wheel.
Repeat this process until the cut is
N
complete.
Be alert to bell ends or any other
N
feature of the pipe that could cause
the cut to close on the wheel if the
pipe is not properly supported and
secured. Bell ended pipes, even
when lying on level ground, can
create a ramp effect that may cause
the pipe to sag or drop when cut,
pinching, binding or clamping the
