WARNING:
3)
Ensure the needle valve is fully closed
.
Move the pump control valve
handle from "squeeze" to "
release". As this is done, the tool will start to open
immediately. Should the operator want to stop the release, return the pump
control valve handle to the squeeze position. The orifice in the needle valve controls the
release rate. As the pipe opens, the pressure in the tool will decrease and the release
rate will slow down. Once the pipe is sufficiently relaxed and the tool does not open any
further, the operator can then
fully
open the needle valve to raise the bars more rapidly
for a complete release.
By opening the needle valve early, a large amount of oil will
enter into the pump and cause it to overflow, which may result in seal damage to
the pump.
Having the pump control valve handle to the release position, start to pump.
Continue to open the tool until it can be removed from the pipe.
Once the tool is fully
open, do not continue to pump.
Continuing to pump will cause hydraulic oil to be
vented from the relief valve to prevent tool damage.
4) To remove the tool from the pipe let the upper bar rest against the pipe. Pull
up
the locking pin then rotate the bottom bar clear of the pipe. The tool may now be lifted
clear of the pipe.
Be aware that the balance of the tool will shift because of the
change in position of the lower bar.
5) If re-rounding of pipe is not to be performed, the grounding spike may now be
removed and the tool can be repacked into its shipping container, in the open position.
RE-ROUNDING THE PIPE, IF REQUIRED
Once the tool is fully open reposition the tool 90
°
from the original squeeze on the top of
the peaks of the squeeze. Squeeze the pipe back to its original shape as outlined in
“Installation on Pipe” and “Squeezing the Pipe” detailed above. Consult your local utility
for their specific recommendations regarding this procedure. The grounding spike may
now be removed and the tool can be repacked into its shipping container, in the
closed position.

RELEASING THE PIPE
1) Unscrew the lock-down bolts located at each end of the clamping bars. It will be
necessary to place the pump control valve into the "squeeze" mode and apply more
pressure to the tool to relieve the upward strain on the bolts created by the pipe trying to
bounce back.
2) To avoid any damage to the pipe it is critical that a slow release rate be achieved. A
release rate of 1/2 inche per minute is recommended. This time allows for the PE pipe
to "flow" minimi
zing the chances of pipe damage. Below 32
°
F (0°C), the release rate
should be slower. Consult your local utility for their specific recommendations regarding
their prescribed release rate.
