Cutting with No. 820 Cutter
1. Open cutter by turning the feed screw counterclock-
wise. Lower the cutter into cutting position. Align the
cutter wheel with the mark on pipe. Cutting threaded
or damaged sections of pipe can damage the cutter
wheel.
Length Gauge Use – Place cutting wheel blade against
the end of pipe and set length gauge pointer to “0”
(Figure 20A)
. Raise cutter and turn carriage hand-
wheel until the pointer is at the length desired. Lower
the cutter into cutting position.
See Figure 20B

2. Tighten the cutter feed screw handle to bring the cut-
ter wheel firmly in contact with the pipe while keeping
the cutter wheel aligned with the mark on pipe.
3. Move the REV/OFF/FOR Switch to the FOR position.
4. With both hands, grasp the pipe cutter feed handle.
5. Depress the foot switch.
6. Tighten the feed screw handle one-half turn per rota-
tion of the pipe until the pipe is cut. More aggressive
tightening of the handle reduces cutter wheel life and
increases burr formation. Do not support the pipe
by hand. Let the cut off piece be supported by the
threading machine carriage and pipe stand.
