General Safety Information

– To avoid serious injuries:
NOTE:
Avoid continuous application of the brakes when riding
down long slopes, as this will cause the internal brake
parts to become very hot, and this may weaken braking
performance. It may also cause a reduction in the amount
of brake grease inside the brake, and this can lead to
problems such as abnormally sudden braking.
Spin the wheel and confirm that the braking force of the
coaster brake is correct.
If the brakes are used frequently, the brake drum may
become hot. Do not touch the brake drum for at least 30
minutes after you finish riding the bicycle.
It is important to completely understand the operation of
your bicycle's brake system. Improper use of your bicycle's
brake system may result in a loss of control or an accident,
which could lead to sever injury. Because each bicycle
may handle differently, be sure to learn the proper braking
technique (including bicycle control characteristics) and
operation of your bicycle. This can be done by consulting
your professional bicycle dealer and the bicycle owner's
manual, and by practicing your riding and braking technique.
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.
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.
Use a wheel with 3x or 4x spoke lacing. Wheels with
radial lacing cannot be used because the spokes and
the wheel can be damaged when applying the brakes
and brake noise can be generated.
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.
If the wheel becomes stiff and difficult to turn, you
should replace the brake shoes or lubricate 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.
