•Smooth shifting will not be possible if the chainrings are incorrectly

General Safety Information

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 re-

check 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.

•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

onto the next-larger rear sprocket or the one after.

•If the bottom bracket shell is not parallel, gear shifting

performance will drop.

•Use the CN-7801/CN-6600/CN-5600 with the FC-5703.

•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.

5. Use the TL-FC16/18 to tighten the cap.

Tightening torque: 0.7 - 1.5 N·m {6 - 13 in. lbs.}

6. Push in the stopper plate and check that the plate pin is

securely in place, and then tighten the bolt of the left

crank arm. (5 mm Allen key)

Note : Each of the bolts should be evenly and equally

tightened to 12 - 14 N·m {106 - 122 in. lbs.}.
