IMPORTANT NOTICE
IMPORTANT NOTICE
• This dealer’s manual is intended primarily for use by professional bicycle mechanics.
Users who are not professionally trained for bicycle assembly should not attempt to install the components themselves using the dealer’s manuals.
If any part of the information on the manual is unclear to you, do not proceed with the installation. Instead, contact your place of purchase or a local
bicycle dealer for their assistance.
• Make sure to read all instruction manuals included with the product.
• Do not disassemble or modify the product other than as stated in the information contained in this dealer’s manual.
• All manuals and technical documents are accessible online at https://si.shimano.com.
• For consumers who do not have easy access to the internet, please contact a SHIMANO distributor or any of the SHIMANO offices to obtain a hardcopy
of the User's Manual.
• Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer.
For safety, be sure to read this dealer’s manual thoroughly before use, and follow it for correct use.
The following instructions must be observed at all times in order to prevent personal injury and physical damage to equipment and surroundings.
The instructions are classified according to the degree of danger or damage which may occur if the product is used incorrectly.
DANGER
Failure to follow the instructions will result in death or serious injury.
WARNING
Failure to follow the instructions could result in death or serious injury.
CAUTION
Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings.

TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
• Be sure to follow the instructions provided in the manuals when installing the product.
Only use SHIMANO genuine parts. If a component or replacement part is incorrectly assembled or adjusted, it can lead to component failure and cause
the rider to lose control and crash.
• Wear approved eye protection while performing maintenance tasks such as replacing components.
Be sure to also inform users of the following:
• Never use alkali- or acid-based solvents such as rust cleaners. If those solvents are used the chain might break and cause serious injury.
• Clean the chain with an appropriate chain cleaner regularly. Intervals between maintenance depend on the use and riding circumstances.
• 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.
• Be careful not to let the hemming of your clothes get caught in the chain while riding. Otherwise you may fall off the bicycle.
• Check the chain for any damage (deformation or crack), skipping, or other abnormalities such as unintended gear shifting. If any problems are found,
consult a dealer or an agency. The chain may break, and you may fall.
For Installation to the Bicycle, and Maintenance:
• Install the inner cover correctly. If it 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.
• The two left crank arm screws should be tightened alternately in stages rather than each fully tightened at once. Use a torque wrench to check that
the 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 screws 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.

TO ENSURE SAFETY
CAUTION
Be sure to also inform users of the following:
• Be careful not to touch the teeth of chainrings. There is a danger of injury.
NOTICE
Be sure to also inform users of the following:
• Check that there is no excess play or looseness in any fastening sections before riding the bicycle. Also, be sure to retighten the crank arm and pedals
at periodic intervals.
• Be sure to keep turning the crank arm during the shift lever operation.
• When the chain is in any of the positions shown in the figures, the chain may come into contact with the chainring or front derailleur and generate
noise. If noise is a problem, shift the chain onto the next largest sprocket or the one after if it is in the position shown in Figure 1. Shift the chain onto
the next smallest sprocket or the one after if it is in the position shown in Figure 2.

• Use a neutral detergent to clean the crank arm and the bottom bracket. Using alkaline or acidic detergents may cause discoloration.
• If pedaling performance does not feel normal, contact your place of purchase.
• Do not wash the bottom bracket with high-pressure jets of water. Water may enter the bearing section and cause noise or adhesion.
• The chainrings should be periodically washed with a neutral detergent. In addition, cleaning the chain with neutral detergent and lubricating it can be
an effective way of extending the life of the chainrings and the chain.
• The cuffs of your clothing may get dirty from the chain while riding.
• This product is not warrantied against damage caused by improper use, abuse, or issues resulting from a crash, unless the circumstance was caused by
a manufacturing fault.
• Products are not guaranteed against natural wear and deterioration from normal use and aging.
• For maximum performance we highly recommend SHIMANO lubricants and maintenance products.

6
TO ENSURE SAFETY
For Installation to the Bicycle, and Maintenance:
• When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from seizing. Use a torque wrench to securely tighten
the pedals. Tightening torque is 35 - 55 N·m. The right crank arm has a right-hand thread, and the left crank arm has a left-hand thread.
• If the bottom bracket shell is not parallel, gear shifting performance will drop.
• If the chain keeps coming off the gears during use, replace the chainrings and the chain.
• When installing the left- and right-hand cups, apply grease and be sure to install the inner cover. Otherwise, the waterproofing performance will
worsen.
• To ensure the best performance, be sure to use only the recommended type of chain.
• If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector, apply grease to the fastening section, then
tighten it to the specified torque.
• If you feel any looseness in the bearings, the bottom bracket should be replaced.
• Use the specified chainring combination. If other chainring combinations are used, it can create poor shifting and cause the chain to jam, resulting in
damage to the bicycle.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using
the product.
