TO ENSURE SAFETY
For Installation to the Bicycle, and Maintenance:
• When installing the hub to the frame, be sure to install the correct non-turn washers to the left and right sides, and securely tighten the hub nuts to
the specified torques. If the non-turn washers are installed to one side only, or if the hub nuts are not tightened sufficiently, the non-turn washer may
fall out, which could cause the hub axle to rotate and the cassette joint to turn.This may then cause the handlebars to be accidentally pulled by the
shifting cable, and an extremely serious accident could result.
• Assemble the wheel with 3x or 4x spoke lacing. Do not spoke the wheel radially.
Otherwise, the spokes or the wheel may get damaged, or noise may occur when braking.
< CT-S500 / CT-S510 >
• Use neutral detergent to clean the chain. Do not use alkali-based or acidbased detergents such as rust cleaners, as they may result in damage and/or
failure of the chain.
• Use the reinforced connecting pin only for connecting the narrow type of chain.
• If connecting pins other than reinforced connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for that type of chain
is used, sufficient connection force may not be obtained, which could cause the chain to break or fall off.
• If it is necessary to adjust the length of the chain due to a change in the number of sprocket teeth, make the cut at some other place than the place
where the chain has been joined using a reinforced connecting pin or an end pin.
The chain will be damaged if it is cut at a place where it has been joined with a reinforced connecting pin or an end pin.
• Check that the tension of the chain is correct and that the chain is not damaged.
If the tension is too weak or the chain is damaged, the chain should be replaced. If this is not done, the chain may break and cause serious injury.
