Step 7: Once locked ensure that the distance between
the set nut and the hydraulic cylinder is 2.11 mm.
Step 8: Start the machine, pull back the upper roller as
far as possible, close the cylinder cutoff valve and start
to pump. Do not pump continuously, allow the tube to
rotate three times for each pumping operation. When
the set nut touches the hydraulic cylinder stop pumping
and do not stop the machine until the tube has rotated
three times. Stop the machine, open the cylinder cutoff
valve to ensure that the hydraulic cylinder recedes and
remove the tube.
