Outer diameter of pipe is smaller than
the maximum cutting depth
Make one cut from the top to the
N
bottom
Outer diameter of pipe is greater than
the maximum cutting depth
Plan first, then cut. Several cuts are
needed – correct sequence is important.
If the pipe is in-ground or otherwise
cannot be rolled:
To reduce the risk of pinching and
N
kickback, always start at the bottom,
use the front and upper part of the
abrasive wheel for cutting.
TSA 230
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.
Next, make a first lateral cut on the
N
top half of the pipe, connecting with
the kerf from the bottom half.
A second lateral cut is then made in
N
the marked area. To keep the pipe
from pinching during this cut, never
cut into the area of the final cut.
Only make the final top cut once all
bottom and lateral cuts have been
completed and connect with one
another.
Always make the final separating
N
cut from the top (approx. 15 % of the
pipe circumference). 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
wheel to make an initial partial cut.
Then, roll the pipe, resecure it and
N
make another partial cut with the
bottom of the wheel.
Repeat until the cut is complete.
N
Be especially alert to belled ends or
N
any other feature that could cause
the kerf to close on the wheel if not
properly supported. 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.
