I've seen this first hand may times trying to take apart devices assembled with such lock washers. They will very much dig into the underside of the bolt head and very much resist your efforts to disassemble the joint.

Now maybe he has a different definition of what it means to lock the joint. If so it would be wise if the manual was updated with full qualification.
