General Safety Information
WARNING
– To avoid serious injuries:
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.
Obtain and read the service instructions carefully prior to installing
the parts.
Loose, worn, or damaged parts may cause serious injury to
the rider.
We strongly recommend only using genuine Shimano replacement parts.
Check that the wheels are fastened securely before riding the bicycle.
If the wheels are loose in any way, they may come off the bicycle and
serious injury may result.
Read these Technical Service Instructions carefully, and keep them in a
safe place for later reference.

The 8-speed hub has a built-in mechanism to support shifting. When this
support mechanism operates during shifting, noise or vibration may
occur. The shifting feel may also change depending on the gear position
at the time of shifting.
Noise may also be generated if the crank arms are turned backward or if
the bicycle is pushed backward when the gear position is 5, 6, 7 or 8.
These occurrences are a normal result of the structure of the internal
gear shifting mechanism, and are not a sign of a malfunction.
The CJ-8S20 cassette joint should only be used with sprockets from 16T
to 23T.
It is recommended that you set the chainrings so that the gear ratios are
approximately 2.1.
Example: F36T – R16T, F38T – R18T, F46T – R22T
In order to maintain proper performance, it is recommended that you ask
the place where you purchased the bicycle or your nearest Pro shop to
carry out maintenance such as greasing the internal hub about once
every two years starting from the first time of use (or once about every
5,000 km if the bicycle is used very frequently). Furthermore, it is
recommended that you use the Shimano internal hub grease or
lubrication kit when carrying out maintenance. If the special grease or
lubrication kit is not used, problems may occur such as the gear shifting
not working correctly.
The internal hub is not completely waterproof. Avoid using the hub in
places where water might get inside it and do not use high-pressure
water to clean the hub, otherwise the internal mechanism may rust.
You should periodically wash the sprockets in a neutral detergent and
then lubricate them again. In addition, cleaning the chain with neutral
detergent and lubricating it can be a effective way of extending the useful
life of the sprockets and the chain.
If the chain keeps coming off the sprockets during use, replace the
sprockets and the chain.
Parts are not guaranteed against natural wear or deterioration resulting
from normal use.
For maximum performance we highly recommend Shimano lubricants
and maintenance products.
For any questions regarding methods of handling or adjustment, please
contact the place of purchase.
Do not disassemble the hub. If you think disassembly might be
necessary, contact the place of purchase.

For A specifications: If the sprocket is an inward
assembling sprocket with 19T or less or for belt drive
specifications, right hand dust cap A will come into
contact with the chain or pulley and so B specifications
should be used instead.
For B specifications: If the sprocket is an inward
assembling sprocket with 16T and thick teeth or for
belt drive specifications, remove right hand dust cap
B before use.
If the yellow setting lines are not aligned, turn the
cable adjustment bolt of the shifting lever to align
the setting lines. After this, move the shifting lever
once more from 4 to 1 and then back to 4 , and
then re-check to be sure that the yellow setting
lines are aligned.
