Most people position the G88 in their weaker hand to hold everything securely, and then turn the T-handle with their stronger hand. All the while holding everything secure while tightening. Don't let the jaws slide over the receiver, hold them tight.
Here shown above on a trombone slide (12H & Bach), and below on a tuba. Always use this grip!
Be sure you get the jaws planted firmly on the mouthpiece stem, so that you 'push' the receiver.
It helps to lay the instrument on a bench or table. Otherwise it can be a two man job.
