-Loosen nut of the cable clamp [12]
-Turn the “high” adjusting screw so the jockey roller [7] is in line with the outside edge of the smallest rear sprocket [8]

2.Put the “low” adjusting screw in the correct position as follows:
-Shift the chain onto the largest rear sprocket
-Loosen nut of the cable clamp
-Turn the “low” adjusting screw so the jockey roller is exactly below the largest rear sprocket [9]
-Tighten the nut of the cable clamp.
3.Adjust the index shift system:
-Shift the chain onto the smallest rear sprocket
-Without turning the crank, turn the shift control one “click”
-Slowly turn the crank forward
-The chain should move from the smallest rear sprocket to the next larger rear sprocket
-Turn the adjusting barrel as needed so the chain moves exactly on to the second rear sprocket and does not rub, jump, or delay.
Chain
WARNING: This bicycle has special high strength chain. Do not use a pliers type chain tools 
to remove the chain. Separate the chain only at an original pin [10]. Never separate the chain
at the master link [11] or at a connecting link [12]. Identify an original pin by either two lines or a square on each end, a master pin by plain ends, and a connecting pin by an indentation on one end. If you remove an original pin from the chain, discard it. Use only a new connecting pin to assemble the chain. If you have any questions, contact HUFFY Bicycles at 1 - 800 - 872 - 2453. If you do not obey these instructions, chain failure can result and cause injury to the rider or to others.
