Groove Tighten the outer cable adjusting barrel until the chain returns to the 2nd sprocket. (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. Also check if the cable is lubricated and if the outer casing is too long or too short.
