General Safety Information
In order to realize the best performance, we recommend that the following
combination be used.
Series
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.
• Use the reinforced connecting pin only for connecting the narrow type of chain.
• There are two different types of reinforced connecting pins available. Be sure to check
the table below before selecting which pin to use. 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.

the chain due to a change in the
number of sprocket teeth, make the cut
at some other place than the place
where the chain has been joined using
a reinforced connecting pin or an end pin. The chain will be damaged if it is cut at a
place where it has been joined with a reinforced connecting pin or an end pin.
• Be careful not to let the cuffs of your clothes get caught in the chain while riding,
otherwise you may fall off the bicycle.
• Check that the tension of the chain is correct and that the chain is not damaged. If the
tension is too weak or the chain is damaged, the chain should be replaced. If this is
not done, the chain may break and cause serious injury.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are
any cracks, the crank arm may break and you may fall off the bicycle.
• 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.
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend that only genuine Shimano replacement parts be used.
• Read these Technical Service Instructions carefully, and keep them in a safe place for
later reference.

note of steps 3. and 4.
Do not disassemble the indicator and shifting lever unit, as this

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.
When cutting the outer casing, cut the opposite end to the end with

• In addition, if pedaling performance does not feel normal, check this once more.
• Check that there is no looseness in any joints or connections before riding the bicycle.
(BB-FC, FC-PD)
• Do not wash the bottom bracket with high-pressure jets of water.
• If you feel any looseness in the bottom bracket axle, the bottom bracket should be
replaced.
• 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 wash the chainrings in a neutral detergent and then lubricate
them again. In addition, cleaning the chain with neutral detergent and lubricating it can
be an effective way of extending the useful life of the chainrings and the chain.
• If the chain keeps coming off the chainrings during use, replace the chainrings and
the chain.
• Apply grease to the bottom bracket before installing it.
• For smooth operation, use the specified outer casing and the bottom bracket cable
guide.
• This front derailleur is for triple front chainwheel use only. It cannot be used with the
double front chainwheel, as the shifting points do not match.
Outer casing holders
• 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 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.
• Be sure to use only the applicable chain and bottom bracket.
• If using a chain case, use the FC-M531 / BB-ES51-AK / BB-ES30-AK combination.
• Operation of the levers related to gear shifting should be made only when the front
chainwheel is turning.
• 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.
