N
Always make the final separating
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:
N
Use only the bottom of the abrasive
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.
N
Roll the pipe, resecure and support
it. Make another partial cut using the
bottom of the wheel and the guard
covering the top of the wheel.
N
Repeat this process until the cut is
complete.
N
Be alert to bell ends or any other
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
cutting wheel and resulting in
severe kickback or other reactive
force.
Cutting Recesses in Pipe
The sequence of cuts (in the illustrations
below, 1 to 4) is recommended:
N
Always make severing cuts so that
the abrasive cutting wheel is not
pinched, bound or clamped.
N
Use wedges and/or leave sections
of pipe to be manually broken out
after cutting. Always continue to
wear appropriate eye protection
when finishing a cut by breaking it
manually.
N
If the severed part remains in the
recess after cutting, do not make
any further cuts – break the part out
manually, using a hammer or other
appropriate tool. Always continue to
wear appropriate eye protection
when finishing a cut by breaking it
manually.
