TO ENSURE SAFETY

• 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 cracking), skipping, or other abnormalities such as unintended gear shifting. The chain may break,

and you may fall. If any problems are found, consult your place of purchase or a distributor.

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 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. Also, after riding approximately 100 km (60 miles), use a torque wrench to re-check the

tightening torques. Thereafter, continue to check the tightening torques periodically. If the tightening torques are too weak or if the mounting screws

are not tightened alternately in stages, the left crank may come off and the bicycle may fall over, and serious injury may occur as a result.

Be sure to also inform users of the following:

• Be careful not to touch the teeth of chainrings. There is a danger of injury.
