1.
Align the machine at the desired cut line, perpendicu-
lar to the center axis of the pipe. The clamping arms
should extend around the pipe and the mounting shoes
should be against the pipe, or close to it.
2.
Start the hydraulic power unit. Set it to provide 22
gpm flow at 3000 psi.
3.
Push both clamping flow levers down simultaneously.
Watch the clamping pressure gauges to ensure that the
pressure is within 1900-2200 psi.
As you operate the machine,
check the clamping pressure
frequently to make sure it
stays above 1700 psi. If it
gets too low, stop the
machine and reclamp it to the
pipe.
4.
When the clamping arms are fully clamped and the
pressure is within 1900-2200 psi, pull both clamping
flow levers up to lock the holding pressure. The pres-
sure will drop quickly to 1850 psi and then slowly to
about 1600 psi.
5.
Repeat the clamp sequence three times. The pressure
should hold above 1700 psi.

UT
The cutting wire spins at very
high speed. If the wire
breaks, segments of the wire
can fragment and be thrown
from the machine at danger-
ous speeds. Make sure all
personnel are at a safe dis-
tance before starting the cut-
ting drive. Serious injury or
death could result from
contact with the wire or as
a result of the wire break-
ing.
1.
Push the feed flow lever down to open the feed circuit.
Figure 3-11. Push the feed flow lever down to supply
power to the feed drive.
2.
Set the feed speed knob to 2.5 gpm.
