Prepare an area where to put down the arm
system after removal. Use for example two
wooden planks on which the flange can
rest.
The screw heads of the cross roller bearing
will stick out further down than the outer
flange, so if placing down the arm system
on a flat surface, the arm system will rest
on the screw heads and be unstable.
