Explanation:
As technicians will need to use both hands while reading the manual, the perfect binding would be extremely inadequate, not allowing the optimization of technicians' work. This is because perfect binding must be used when the manual will be used by someone who will not have their hands full, otherwise the formatting must adapt to the work of technicians, promoting speed and work optimization.
