General Safety Information
WARNING – To avoid serious injuries
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 recom -
mended 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.
CAUTION – To avoid serious injuries
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.
