User manual SHIMANO FRONT DRIVE SYSTEM TECHNICAL SERVICE INSTRUCTIONS

[. . . ] · Use a front chainwheel which is compatible with 9-speed chains in conjunction with Shimano CN-7701, CN-HG93 and CN-HG73 chains. If a chainwheel for an 8-speed chain or less is used, front chainwheel gear shifting problems may occur, or the chain pins might fall out, causing the chain to break. · The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened all at once. Use a torque wrench to check that the final tightening torques are within the range of 12 - 15 N·m. [. . . ] · If the chain keeps coming off the chainrings during use, replace the chainrings and the chain. · When the chain is in the position shown in the illustration, the chain may contact the front chainrings or front derailleur and generate noise. If the noise is a problem, shift the chain Front onto the next-larger rear sprocket or the one after. chainrings · Apply grease to the bottom bracket before installing it. · For smooth operation, use the specified outer casing and the bottom bracket cable guide. Rear · This front derailleur is for triple front chainwheel use only. It cannot be used with the sprockets double front chainwheel, as the shifting points do not match. · When installing the top route type, choose a frame that has three outer casing holders as shown in the illustration at right. · Use an outer casing which still has some length to spare even when the handlebars are turned all the way Outer casing holders to both sides. Furthermore, check that the shifting lever does not touch the bicycle frame when the handlebars are turned all the way. · A special grease is used for the gear shifting cable (SIS-SP41). Do not use DURA-ACE grease or other types of grease, otherwise they may cause deterioration in gear shifting performance. · Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly. · Operation of the levers related to gear shifting should be made only when the front chainwheel is turning. · If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the plastic parts of the shifting lever, this may cause the plastic parts to crack or become discolored. Therefore, you should make sure that the brake fluid does not adhere to these plastic parts. The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, but such parts should be cleaned with alcohol beforehand to prevent foreign particles from adhering. · Do not disassemble the indicator and shifting lever unit, as this may damage them or cause mis-operation. · Parts are not guaranteed against natural wear or deterioration resulting from normal use. · For maximum performance we highly recommend Shimano lubricants and maintenance products · For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a professional bicycle dealer. When lever (A) is pressed once, there is a shift of one step from a small chainring to a larger chainring. Install the brake lever in a position where it will not obstruct brake operation. Do not use in a combination which causes brake operation to be obstructed. In the case of carbon handlebars, it may be necessary to lower the tightening torque in order to prevent damage to the handlebar. [. . . ] (This also applies if shifting becomes difficult during use. ) If the chain falls to the crank side. If shifting is difficult from the intermediate chainring to the largest chainring. If shifting is difficult from the intermediate chainring to the smallest chainring. Do not remove the Pro-Set alignment block at this time.
