These Service Instructions describe the operation method when using the RAPIDFIRE SL-M660 in combination with the RD-M662 top normal-type rear derailleur. If using in combination with a reverse spring-type derailleur, the operations and indicator displays will be reversed.
Install the inner hole cover by turning it as shown in the illustration until it stops. Do not turn it any further than this, otherwise it may damage the screw thread.
<If not installing the indicator> 1. Remove the indicator bracket protective cover which is attached
to the indicator, starting from the shorter tab as shown in the illustration.
This release lever is equipped with a 2-way release mechanism which allows release operations to be carried out by either pushing or pulling the lever. Both lever (A) and lever (B) always return to the initial position when they are released after shifting. When operating one of the levers, always be sure to turn the crank arm at the same time.
2. First insert the tab of the indicator bracket protective cover into
the slot which does not have a o mark, and then set it onto the shifting lever unit and secure it with the indicator fixing screw.
Note
If gear shifting operations do not feel smooth, wash 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. If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley. If the wheel becomes stiff and difficult to turn, you should lubricate it with grease. Do not apply any oil to the inside of the hub, otherwise the grease will come out. You should periodically wash the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain. If the chain keeps coming off the sprockets during use, replace the sprockets and the chain. Use a frame with internal cable routing is strongly discouraged as it has tendencies to impair the SIS shifting function due to its high cable resistance. Always be sure to use the sprocket set bearing the same group marks. Never use in combination with a sprocket bearing a different group mark. Group marks Use an outer casing which still has some length to spare even when the handlebars are turned all the way 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. For smooth operation, use the specified outer casing and the bottom bracket cable guide. 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.

Do not push the brake lever against the indicator cover, otherwise it may cause problems with the operation of the needle. * If the rear derailleur moves to a large degree, such as in bicycles with rear suspension, it is recommended that you replace the cap with the Derailleur side accessory aluminum cap. The end of the outer casing which has the aluminum cap should be at the derailleur side.

For each sprocket, the surface that has the group mark should face outward and be positioned so that the wider part of each sprocket and the A part (where the groove width is wide) of the freewheel body are aligned.

If not using the indicator, this shifting lever can be installed either on the inside or the outside of the brake lever. If adjusting the position, remove the indicator, and then be sure to secure it in the new position with the two fixing bolts.

This service instruction explains how to use and maintain the Shimano bicycle parts which have been used on your new bicycle. For any questions regarding your bicycle or other matters which are not related to Shimano parts, please contact the place of purchase or the bicycle manufacturer.
Install the shifting lever in a position where it will not obstruct brake operation and gear shifting operation. Do not use in a combination which causes brake operation to be obstructed. When installing the components to carbon frame/handle bar surfaces, verify with the manufacturer of the carbon frame/parts for their recommendation on tightening torque in order to prevent over tightening that can cause damage to the carbon material and/or under tightening that can cause lack of fixing strength for the components.
