First remove 14 of the 16 screws (6 from the top and 8 from the

positions of each screw to ensure that they are correctly
replaced after service work.

Stand firmly next to the gantry and hold it with both hands, while
the other person removes the remaining two screws.
Lift the gantry off the guide slide and carry it out of the machine.
