1) Wrap the clamp around the CV boot and thread the tail through the buckle.  Draw it tight.

2) Insert the tail of the clamp into the head of the banding tool and slide it through the slot of the winding mandrel.

3) Tension the clamp with a clockwise motion using a ¾” socket wrench.

4) After sufficient tension has been applied (the clamp is tight enough to hold the boot from turning on the joint but not too tight that the boot is damaged), lever the tool back over the buckle to put a bend in the clamp to hold the tension (you may want to tap it with a hammer to put a good crease).

5) Cut off excess band with the tin cutter.

6) Complete clamp installation by tapping down the tail of the clamp against the buckle and then tapping down the buckle ears to hold the clamp tail. 

The professional Banding Tool works similar to the Economy Banding Tool but it has a built in ratchet and cutter.
