TO ENSURE SAFETY
WARNING
· Be sure to follow the instructions provided in the manuals when installing the product. Only use SHIMANO genuine parts. If a component or replacement part is incorrectly assembled or adjusted, it can lead to component failure and cause the rider to lose control and crash.
·
Wear approved eye protection while performing maintenance tasks such as replacing components.
Be sure to also inform users of the following: · Because each bicycle may
handle slightly differently depending on the model, be sure to learn the
proper braking technique (including brake lever
pressure and bicycle control characteristics) and operation of your bicycle.
Improper use of your bicycle’s brake system may result in a loss of control,
which could lead to serious injury due to a fall or collision.
5
TO ENSURE SAFETY
· Use brake levers with mode switching mechanism in the combinations shown in the figures. The brake levers are equipped with a mode switching mechanism which can be used to make them compatible with cantilever brakes, roller brakes or V-BRAKE brakes with power modulator. (SB-C6000-8 / SB-C3000-7 is compatible with roller brakes or V-BRAKE brakes with power modulator. Note that SB-C6000-8 / SB-C3000-7 is not compatible with cantilever brakes.) If the incorrect mode is selected, it may result in either excessive or insufficient braking force, which is highly dangerous. Select the correct mode as shown in the figures.

· Check that the wheels are fastened securely before riding the bicycle. You may fall or collide and be seriously injured.

TO ENSURE SAFETY
For Installation to the Bicycle, and Maintenance:
· When securing the brake arm to the frame, be sure to use an arm clip that
matches the size of the chainstay, and securely tighten them with the clip
bolt and clip nut to the specified tightening torque. Use a lock nut with a
nylon insert (self-locking nut) as the clip nut. It is recommended that
Shimano made clip bolts, clip nuts, and arm clips be used. If the clip nut
comes off the brake arm, or if the clip bolt or 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 result in serious injury due to a
fall or collision.
· 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 on 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, resulting in the handlebars being accidentally pulled by the gear
shifting cable and an extremely serious accident.
Disc brake rotor · Please use extra caution to keep your fingers away from the
rotating disc brake rotor. The disc brake rotor is sharp
enough to inflict severe injury to your fingers if caught within the openings
of moving rotor.
· Do not touch the calipers or disc brake rotor while riding or immediately after dismounting from the bicycle. The calipers and disc brake rotor will become hot when the brakes are operated, so you may get burned if you touch them.
· Do not allow any oil or grease to get onto the disc brake rotor and brake pads. Riding the bicycle with oil or grease on the disc brake rotor and brake
pads may prevent the brakes from operating and result in serious injury due to a fall or collision.
· Check the thickness of the brake pads and do not use them if they have a thickness of 0.5 mm or less. Doing so may 2 mm
0.5 mm
prevent the brakes from operating and result in serious injury due to a fall or collision.
· Do not use the disc brake rotor if it is cracked or deformed. The disc brake
rotor may break, and result in serious injury due to a fall. · Do not use the
disc brake rotor if its thickness is 1.5 mm or less. Also do not use it if the
aluminum surface becomes visible. The disc brake rotor may
break, and result in serious injury due to a fall.
Coaster brake hub · When using a reversed dropout, use a chain adjuster to
remove excess slack from the chain.
7
TO ENSURE SAFETY
CAUTION
Be sure to also inform users of the following: · Be sure to shift the shift
lever one gear at a time. During shifting, reduce the force being applied to
the pedals. If you try to force operation of the
shift lever or suddenly perform multi-shifting while the pedals are being
turned strongly, your feet may come off the pedals and the bicycle may fall
over, which could result in serious injury. Operating the shift lever to
multi-shift to a light gear may also cause the outer casing to spring out of
the shift lever. This does not affect the capabilities of the shift lever
because the outer casing returns to the original position after shifting. ·
When the brake is used frequently, do not touch the area around the brake for
at least 30 minutes after riding the Area around the brake bicycle. The area
around the brake may become hot.
Coaster brake specifications · Do not continuously apply the brakes when
riding down long slopes. This will cause the internal brake parts to become
very hot, weakening braking
performance, as well as causing a reduction in the amount of brake grease
inside the brake, which can lead to problems such as abnormally sudden
braking.
· Perform the bed-in procedure and check that the braking force of the coaster
brake is correct.
NOTICE
Be sure to also inform users of the following: · The gears can be shifted
while lightly pedaling, but on rare occasions the pawls and ratchet inside the
hub may produce some noise afterwards as part
of normal gear shifting operation. In addition, a loud sound may be
temporarily emitted if the gears are shifted while strongly pedaling with
E-BIKE, etc., but this is normal.
· The internal geared hub is not completely waterproof. Avoid using the hub in
places where water might get inside and do not use high-pressure water to
clean the hub, otherwise the internal mechanism may rust.
· Do not disassemble the hub. If you need to disassemble it, contact the place
of purchase.
· All of the following occurrences are due to the internal gear-shifting
structure and are not the failure of the internal components.
Phenomenon
Noise occurs when the pedals rotate. Noise occurs when the bicycle is pushed
backward. The hub has a built-in mechanism that supports gear shifting and
when the mechanism operates during gear shifting, noise and vibrations occur.
Depending on gear position, gear-shifting may feel different.
Noise occurs when pedal rotation is stopped during riding.

· Products are not guaranteed against natural wear and deterioration from
normal use and aging. · For maximum performance we highly recommend Shimano
lubricants and maintenance products.
Coaster brake specifications · If the wheels are not rotating smoothly, you
need to replace or grease the brake shoes. Consult the dealer where you made
the purchase.
8
TO ENSURE SAFETY
For Installation to the Bicycle, and Maintenance: · The cassette joint should
only be used with sprockets with 16 to 23T. · The gear ratio of the front
chainring to the rear is about 2.1-to-1.
Example) For 26 inch wheels
Front Rear
36T
38T
46T
16T
18T
22T
· To maintain the product in good working order, it is recommended to have the
place of purchase or a distributor carry out maintenance such as lubrication
of the internal parts about once a year from the first time of use (once every
2,000 km if the bicycle is used very frequently). If the bicycle is used under
harsh conditions, more frequent maintenance is required. Also, for carrying
out maintenance, the use of SHIMANO internal geared hub grease or a
lubrication kit is recommended. If SHIMANO grease or a SHIMANO lubrication kit
is not used, problems such as a malfunction in gear shifting may occur.
· If the wheel becomes stiff and difficult to turn, perform an inspection.
· The chainrings and sprockets should be periodically washed with a neutral
detergent. In addition, cleaning the chain with neutral detergent and
lubricating it can be an effective way of extending the life of the
chainrings, sprockets, and the chain.
· If the chain keeps coming off the gears during use, replace the chainrings,
sprockets, and the chain.
Coaster brake specifications · Use a wheel with 3x or 4x spoke lacing. Wheels
with radial lacing cannot be used. Otherwise, the spokes or the wheel may get
damaged, or noise may
occur when braking.
· If the wheel becomes stiff and difficult to turn, you should replace the
brake shoes or lubricate with grease.
· Use only the specified grease for the brake shoes and when using a
lubrication kit, remove the brake shoes to avoid contact with the oil.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using the product.

MAINTENANCE
Oil maintenance of the internal assembly
Oil maintenance of the internal assembly
To maintain the product in good working order, it is recommended to have the
place of purchase or a distributor carry out maintenance such as lubrication
of the internal parts about once a year from the first time of use (once every
2,000 km if the bicycle is used very frequently). If the bicycle is used under
harsh conditions, more frequent maintenance is required. Also, for carrying
out maintenance, the use of SHIMANO internal geared hub grease or a
lubrication kit is recommended. If SHIMANO grease or a SHIMANO lubrication kit
is not used, problems such as a malfunction in gear shifting may occur.
