NOTE: When setting Structural Rivets such as Marson Klik-Lock™, Huck Maga-Lock™ or
any other similar type Structural Rivets, it will be necessary for you to change supplied
collet case (96), jaws (95) and use the appropriate size nosepieces (91, 92, 93 or 94)
for the rivet diameter you are installing.
