Mounting The Machine On The Pipe - Wachs WS-8460 User Manual

Diamond Wire Saw User's Manual
CAUTION
Lift the machine ONLY on the
lifting eyes provided. Lifting
on any other component
could damage the machine.
NOTE
The flow on the clamp circuit
is set internally at 4 gpm.
CAUTION
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.

OUNTING THE
See "Rigging the Machine" in Chapter 1 for instructions on
lifting the machine to position it for horizontal or vertical
cuts.
• Attach lifting shackles to the appropriate lift eyes for the
orientation of the machine.
• Before lowering the machine subsea to the cutting loca-
tion, make sure the clamping arms are fully open.
Set the controls on the TCP as follows:
• All flow levers up (flow off).
• Cutter speed knob to 17.5 gpm
• Feed speed knob to 1.5 gpm
• (Clamp flow is preset to 4 gpm)
• Clamp direction to ENGAGE
• Feed direction to FORWARD
• (Cutter direction is preset to forward).
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.
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.
