Solution
Turn jack control valve fully clockwise to close.
Close pump control valve fully as above
Check oil level in the jack correctly and top up
if necessary
Follow instructions to check oil level in the jack
correctly
Unscrew the check screws until the threads
are clear of the check screw block
Leave the pipe for a few hours to return to its
original shape, if this does not work we have a
selection of re-rounding tools to help make any
size pipe round again, see
Check the correct size and SDR squeeze plates
are being used before squeezing the pipe
Where this is required users are advised to
consider using 2 squeeze tools
