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 cause
serious injury.
• 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.
Note
• In addition, if pedaling performance does not feel normal, check this once more.
• 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.
• Do not wash the bottom bracket with high-pressure jets of water.
• If you feel any looseness in the bearings, the bottom bracket should be replaced.
• 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.
• 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.
• Apply grease to the left and right adapters before installing them.
• Be sure to read the service instructions for the Front Drive System in
conjunction with these service instructions.
• 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.
