STEP 7:  
Screw the threaded end of the newCABLE (68128) (2) approximately 3/4” into the end of the WEIGHT STACK SHAFT (1) and  
tighten jam nut securely.  
If the HEAD PLATE does not sit on top of the first WEIGHT PLATE, push the head plate down, insert the SELECTOR PIN and  
perform several repetitions on the machine. This will relax the cable system and prevent the HEAD PLATE from lifting up.  
If after completing the previous step, the HEAD PLATE still does not sit on top of the first WEIGHT PLATE or if there is excess  
slack in the cable system, adjust the threaded end of the CABLE accordingly and retighten the jam nut.
