User manual DAHON RD-7800 TECHNICAL SERVICE INSTRUCTIONS

[. . . ] · If connecting pins other than reinforced connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for the type of chain is used, sufficient connection force may not be obtained, which could cause the chain to break or fall off. Chain 10-speed super narrow chain such as CN-7801 / 6600 Reinforced connecting pin with groove (3) If the smallest sprocket is 15T or 16T · The end of the outer casing which has the aluminum cap should be at the derailleur side. Derailleur side Aluminum cap Plastic cap or 4-mm cap 4-mm cap Largest sprocket Largest chainring 5. SIS Adjustment Operate the shifting lever several times to move the chain to the 2nd sprocket. [. . . ] · Read these Technical Service Instructions carefully, and keep them in a safe place for later reference. In order to realize the best performance, we recommend that the following combination be used.

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.

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). [. . . ] Next, set the chain to the smallest sprocket and repeat the above to make sure that the pulley does not touch the sprocket.
