Î When both spacers lie on the lower squeezing pipe after renewed lowering of the upper squeezing
pipe, then screw the counter pressure screws fully downwards.
Î Finally relieve the pressure in the hydraulic cylinder by opening the pressure relief valve. The squeezing
pressure should only be achieved over longer periods of time over the counter pressure screws.
Î The squeezing device is moved outwards again, as described, after ending the work.
The lower squeezing pipe should be secured by pumping down the upper squeezing pipe and by fixing by
means of the counter pressure screws to transport/secure the squeezing device.
It cannot fall out or be lost.
Only for 53220: Use of the 160-225 distance adapter
Î In order to squeeze pipes with SDR 17.6 and a pipe outer diameter of 160 mm the distance adapter
must be moved from the upper position in the frame into the lower position.
If the upper squeezing pipe cannot be pumped low enough, despite correct adjustments, it may be that
the spindle screw is not unscrewed enough out of the cylinder piston.
Move the upper squeezing pipe up again a little, insert the ratchet end of the pump lever into the mount
for the hydraulic cylinder, hold the cylinder piston firmly and turn it out a bit further using both hands.
Only take hold of the cylinder piston when the upper squeezing pipe has come to a standstill. You
can otherwise crush the hands/fingers.
