General Safety Information
Technical Service Instructions
WARNING
• 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 you may fall off the bicycle.
• 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 - 14 N·m. Furthermore, after riding approximately 100 km (60 miles), use a torque wrench to recheck the tightening torques. It is also important to periodically check the tightening torques. If the tightening
torques are too weak or if the mounting bolts are not tightened alternately in stages, the left crank arm may
come off and the bicycle may fall over, and serious injury may occur as a result.
• 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.
• If the inner cover is not installed correctly, the axle may rust and become damaged, and the bicycle
may fall over and serious injury may occur as a result.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or
damaged parts may cause the bicycle to fall over and serious injury may occur as a result. We
strongly recommend only using genuine Shimano replacement parts.
• Obtain and read the service instructions carefully prior to installing the parts. If adjustments are
not carried out correctly, the chain may come off and this may cause you to fall off the bicycle which
could result in serious injury.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.
CAUTION
• If the chain is on the smallest or intermediate chainring, there is the danger of injury from the tips of
the teeth on the largest chainring.

Note
• Make sure that the chainring combination matches the front chainwheel tooth configuration in the
Product specifications table. If other combinations are used, the distance between the chainrings will
be incorrect and the chain might slip off and get caught in between them.
• 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

sprockets
• Before riding the bicycle, check that there is no play or
looseness in the connection. Also, be sure to retighten the
crank arms and pedals at periodic intervals.
• If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector,
apply grease to the connector and then tighten it to the specified torque.
• If you feel any looseness in the bearings, the bottom bracket should be replaced.
• In addition, if pedaling performance does not feel normal, check this once more.
• Do not wash the bottom bracket with high-pressure jets of water.
• When installing the left and right adapters, be sure to install the inner cover too, otherwise the
waterproofing performance will drop.
• Apply grease to the left and right adapters before installing them.
• To ensure the best performance, be sure to use only the specified type of chain. The wide type of
chain cannot be used.
• If the chain keeps coming off the chainrings during use, replace the chainrings and the chain.
• 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.
• The cuffs of your clothing may get dirty from the chain while riding.
• 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.
