TO ENSURE SAFETY
• 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 it.

• 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.
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.
