Step 1: First, knot the main line to make a snap.
Step 2: Put the main line snap on the rod leader as shown in the picture.
Step 3: Use your left forefinger to press down on the line to prevent it from coming off.
Step 4: Hold the rod tip and the snap with your left hand, and tug on the line with your right hand to snap the snap onto the rod tip.
Step 5: Being tied up and finished, pull the main line tight again to see if it is firm.
