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.
NOTE:
You can shift gears while pedaling, but on rare occasions
the pawls and ratchet inside the hub may produce some
noise afterwards as part of normal gear shifting operation.
The CJ-8S20 cassette joint should only be used with
sprockets from 16T to 23T.
If using a chain tensioner, use the special CS-S500 18T
or 20T sprocket with chain guard. Do not use any other
types of sprockets, otherwise the chain may come off the
sprockets.
If the wheel becomes stiff and difficult to turn, you should
lubricate it with grease.
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.
