There would be no reason for using a putt call for general hunting purposes as it is an alarm warning. It is very difficult to make on a mouth call anyway, so I wouldn't be concerned with making the putt by mistake or trying to learn it.
The cutt is an excited hen call used to entice the gobbler. On a diaphragm it is done by mouthing "chop" in a random, staccato fashion.
The cluck is an all purpose content/ location call, as in "I'm over here." It is made by mouthing the word "chuck". Used by a hunter, it is known as a "confidence" call to assure incoming birds that all is well. A single cluck is also ideal to get an in-range gobbler that is searching for the hen to raise his head for your shot.
In a hunting setup, you might start by emitting some soft yelps and listen for a response. If none, wait a few minutes and yelp a little longer and louder. If still no response, wait a while and turn up the excitement and volume by mixing loud cutting in with some yelping. Don't be afraid to make a racket for 20 to 30 seconds. Then shut up. For 15 minutes. Use a watch if you have to. A lot of toms will sneak in to investigate, without gobbling or strutting, so just because you don't hear a gobble doesn't mean one isn't there. This is where the confidence calling comes in. Some mild scratching in the leaves (three short strokes) and an occasional cluck call help to convince a gobbler that a hen is nearby.
That's the nutshell version. Most diaphragm calls have decent user instructions on the packaging. Your biggest challenge will be learning when to use each call, if at all. Good luck.
