(clockwise) Loosen the outer casing adjustment barrel until the chain touches the 3rd sprocket and makes noise. (counter clockwise) Outer casing adjustment barrel Outer casing adjustment barrel 3. Low adjustment Turn the low adjustment screw so that the guide pulley moves to a position directly in line with the largest sprocket. Best setting The best setting is when the shifting lever is operated just enough to take up the play and the chain touches the 3rd sprocket and makes noise. * Return the lever to its original position (the position where the lever is at the 2nd sprocket setting and it has been released) and then turn the crank arm clockwise. If the chain is touching the 3rd sprocket and making noise, turn the outer casing adjustment barrel clockwise slightly to tighten it until the noise stops and the chain runs smoothly. Operate lever to change gears, and check that no noise occurs in any of the gear positions. Note · If gear shifting operations cannot be carried out smoothly, clean the derailleur and lubricate all moving parts. · If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur. · You should periodically clean the derailleur and lubricate all moving parts (mechanism and pulleys). · If gear shifting adjustment cannot be carried out, check the degree of parallelism at the rear end of the bicycle. [. . . ] Then turn the B-tension adjustment screw to adjust the guide pulley as close to the sprocket as possible but not so close that it touches. Next, set the chain to the smallest sprocket and repeat the above to make sure that the pulley does not touch the sprocket. Largest sprocket Smallest sprocket For the best SIS performance, periodically lubricate all power-transmission parts. These service instructions are printed on recycled paper.
