To reform and grip a ball with the maximum force possible the jaw quality must be maintained.
It is important to monitor jaw quality during use.
The two jaws must also align as good as possible.
The maximum error of any misalignment side to side and in closing height is 5% of the ball diameter.
Cavity contamination is also a cause of poor jaw quality that can reduce the grip force. See the section on jaw cleaning.
