TO ENSURE SAFETY
TO ENSURE SAFETY
• Be sure to follow the instructions provided in the manuals when installing the product.
It is recommended to use genuine Shimano parts only. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over,
which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious injury.
•
Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
• After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
• Intervals between maintenance depend on the use and riding circumstances. Clean the chain with an appropriate chain cleaner regularly. Never use
alkali based or acid based solvents, such as rust cleaners. If those solvent be used chain might break and cause serious injury.
• 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:
• 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.
• The two left crank arm mounting bolts should be tightened in stages rather than fully tightened 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 100km (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.
Be sure to also inform users of the following:
• Be careful to keep body parts away from the sharp teeth of chainrings.
