5.3.2 Laminating instructions
5.3.2.1 Laminating a thigh socket
INFORMATION
The 4X46 lamination aid must be screwed in while laminating. First the
clamping pre-tension must be increased using the cylinder head screw
to the point where the threaded part can still be screwed in and out.
Once the pre-tension is set in this manner, the threaded part is replaced
with the lamination aid.
After laminating, unscrew the lamination aid and install the threaded part.
