General Safety Information

WARNING

– To avoid serious injuries:

When securing the brake arm to the frame, be sure to

use a brake arm clip that matches the size of the

chainstay, and securely tighten them with the clip screw

and clip nut to the specified tightening torque.

Use a lock nut with a nylon insert (self-locking nut) for the

clip nut. It is recommended that standard Shimano parts

be used for the clip screw, clip nut and brake arm clip.

In addition, use a brake arm clip that matches the size of

the chainstay.

If the clip nut comes off the brake arm, or if the clip screw

or brake arm clip becomes damaged, the brake arm may

rotate on the chainstay and cause the handlebars to jerk

suddenly, or the bicycle wheel may lock and the bicycle

may fall over, causing serious injury.

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-NX10 cassette joint should only be used with

sprockets from 16T to 23T.

If the wheel becomes stiff and difficult to turn, you should

lubricate it with grease.

Do not apply any lubricant to the inside of the hub,

otherwise the grease will come out.

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.
