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:
•
Clean the chain and QUICK-LINK with an appropriate chain cleaner regularly. Intervals
between maintenance depend on the use and riding circumstances. Never use alkali
based or acid based solvents, such as rust cleaners. If those solvents are used the chain or
QUICK-LINK might break and cause serious injury.
For installation to the bicycle and maintenance
•
Install the sprockets with the wide protrusions and grooves aligned. If the lock ring is
tightened with the sprockets improperly positioned, the splines on the sprockets may be
damaged during tightening. That may cause a sudden release of resistance on the
wrench being used to tighten the lock ring, which in turn may cause injury. In addition, if
the bicycle is ridden with the sprockets improperly installed, damage or chain skip may
occur, which can cause the rider to fall over, resulting in serious injury.
Align the protrusion with the groove.
