The serve grip technique continues

Next in serve grip, you have to bend knees and bring your racket down behind you back in a throwing position. Your racket swing should be timed to contact the ball as it reaches the top of the toss - about 15cm above your outstretched racket and slightly in front of you. The higher you make contact, the more power you will be able to generate. Next important thing is actually to snap your wrist, following through across your body. The timing to contact the ball requires more practice at least to me and really requires much sharpness.
