[. . . ] General Safety Information WARNING · Use neutral detergent to clean the chain. Do not use alkali-based or acid based detergent such as rust cleaners as it may result in damage and/or failure of the chain. [. . . ] Connection and securing of the cable Connect the cable to the rear derailleur and, after taking up the initial slack in the cable, re-secure to the rear derailleur as shown in the illustration. Tightening torque: 5 - 7 N·m {44 - 60 in. lbs. } Pull Tighten the outer cable adjusting barrel until the chain returns to the 2nd sprocket. (clockwise) Groove Note: Be sure that the cable is securely in the groove. Loosen the outer casing adjustment barrel until the chain touches the 3rd sprocket and makes noise. (counter clockwise) Specifications Type Total capacity Largest sprocket SS 29 teeth or less 27T 11T 14 teeth or less GS 37 teeth or less 27T 11T 22 teeth or less 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. For the best SIS performance, periodically lubricate all power-transmission parts. 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.
