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. Stay a safe dis-
tance from the machine, or
behind a protective barrier,
when operating it topside.
Serious injury or death
could result from contact
with the wire or as a result
of the wire breaking.
Before lowering the machine subsea, test all three drive cir-
cuits to make sure they are working.
Figure 3-10. Attach the hydraulic hoses as shown.
The ports marked “A” are pressure lines from the
TCP; the ports marked “B” are return lines to the
TCP.
