Be sure to also inform users of the following:
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.
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.
Check that the wheels are fastened securely before riding the bicycle. You may fall or collide and be seriously
injured.
Brake
Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may fall
forward, and serious injury may result.
Because the required braking distance will be longer during wet weather, reduce your speed and apply the
brakes early and gently. You may fall or collide and be seriously injured.
A wet road surface may cause tires to lose traction; therefore, to avoid this, reduce your speed and apply the
brakes early and gently. If the tires lose traction, you may fall and be seriously injured.
Disc brake rotor
Keep your fingers away from rotating disc brake rotors. Disc brake rotors are sharp enough to severely injure
your fingers if caught within the openings of a disc brake 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.

2 mm 0.5 mm
For installation to the bicycle and maintenance
< CT-S500 / CT-S510 >
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 prevent the brakes from operating and result in serious injury.
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 rear dropout, use a chain adjuster to remove excess slack from the chain.
For information on products that can be installed, check the compatibility information (
https://productinfo.shimano.com ).
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 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.
Assemble the wheel with 3x or 4x lacing, and do not spoke the wheel radially.
Otherwise, the spokes or the wheel may get damaged, or noise may occur when braking.
Never use alkali- or acid-based solvents such as rust cleaners. If those solvents are used the chain might break
and cause serious injury.
TO ENSURE SAFETY
6
Clean the chain with an appropriate chain cleaner regularly. Intervals between maintenance depend on the
use and riding circumstances.
Use the reinforced connecting pin only for connecting the narrow-type chain. If connecting pins other than
reinforced connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for that
type of chain is used, sufficient connection force may not be obtained, which could cause the chain to break
or skip.
If it is necessary to readjust the length of the chain due to a change in the number of sprocket teeth, make the
cut at some other place than the place where the chain has been joined using a reinforced connecting pin or
an end pin.
The chain will be damaged if it is cut at a place where it has been joined with a reinforced connecting pin or
an end pin.
Reinforced connecting pin
Link pin End pin
Check that the tension of the chain is correct and that the chain is not damaged. If the tension is too weak or
the chain is damaged, the chain should be replaced. If this is not done, the chain may break and cause serious
injury.

Be sure to also inform users of the following:
Area around the brake
Shift the shift lever one or two gears at a time. During shifting, reduce the pedal pressure. If you try to force
operation of the shift lever or suddenly shift three or more gears 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.
Disc brake type
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.
Disc brakes have a bed-in period, and the braking force will gradually increase as the bed-in period progresses.
Accidents or falls may occur due to losing control of the bicycle, possibly resulting in serious injury. The same
thing will happen when the brake pads or disc brake rotor are replaced.
Coaster brake type
Do not touch the coaster brake while riding or immediately after dismounting from the bicycle. The coaster
brake will become hot when the brakes are operated, so you may get burned if you touch them.
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.
Roller brake type
When the brake is used frequently, do not touch the area around the brake for at least 30 minutes after
riding the bicycle. The area around the brake may become hot.
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

Be sure to also inform users of the following:
For installation to the bicycle and maintenance
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 jets of water to clean the hub, otherwise the internal mechanism may
rust.
The following phenomena occur due to the internal gear-shifting structure and are not a failure of the
internal components.

In order to maintain proper performance, it is recommended that you lubricate the internal unit after riding
1,000 km from the start of use, then after about once every year (or once about 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 the shifting unit may occur.
If the wheel becomes stiff and difficult to turn, perform an inspection.
The gears should be periodically washed with a neutral detergent then lubricated. In addition, cleaning the
chain with a neutral detergent and lubricating it can be an effective way of extending the life of the gears
and chain.
If the chain keeps coming off the gears during use, replace the sprockets and chain.
If using a chain tensioner, use the special CS-S500 18T or 20T sprocket with chain guard. Do not use any other
types of sprocket, otherwise the chain may come off the sprockets.

The actual product may differ from the illustration because this manual is
intended mainly to explain the procedures for using the product.
When you perform oil maintenance, use the SG-S700 OIL or TL-S703 maintenance kit.
When you replace the oil, follow the manual for TL-S703. When you replace the seal on the right side, use TL-
S704. If SG-S700 OIL is not used, problems such as an oil leakage and shifting unit malfunction may occur.
Clean the chain tensioner periodically and lubricate all moving parts and pulleys.
If there is a large amount of excess play in the pulleys and an abnormal amount of noise is generated while
riding, replace the pulleys.
Do not disassemble the pulley unit.
If the tension applied is too strong, noise may be generated while riding.
If the chain becomes elongated and excessive looseness occurs, readjust the chain tension.
This product is for single front chainrings only.

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 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.
If it is not installed correctly, braking performance will suffer. Be very careful when installing it.
If excessive force is applied to the brake arm to secure it, a problem such as noise will occur and the
wheel will become difficult to turn.
After installing the arm clip, check that the clip bolt protrudes approximately 2 - 3 mm from the
end face of the clip nut.

Oil maintenance of the internal assembly
For internal 8-speed (oil maintenance kit: Y00298010)
In order to maintain proper performance, it is recommended that you lubricate the internal unit after riding
1,000 km from the start of use, then after about once every year (or once about 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
the shifting unit may occur.
Remove the inner cable from the pulley guide, and remove the inner cable fixing bolt unit.

Cautions regarding handling of SG-S700 OIL
When replacing the oil, be careful that no oil gets on the disc brake rotor, pads, on the rim when using
rim brakes, etc. If oil gets on any of these parts, there is a danger that brake performance may be
reduced. Take care of this problem according to the procedures in the brake instruction manual.
Since there is a risk of explosion or fire, do not smoke, eat, or drink while using this oil. In addition,
keep it away from ignition sources such as heat, sparks, open flames, or high temperatures and prevent
it from catching fire due to static electricity sparks or other sparks.
Use only outdoors or in a well-ventilated area. Inhalation of oil mist or vapors may cause nausea. Be
careful to provide ventilation and use a respirator type mask. If mist or vapor is inhaled, go immediately
to an area with fresh air. Cover up with a blanket. Stay warm and stable and seek professional medical
advice.
Use appropriate eye protection when handling, and avoid contact with eyes. In the event of eye
contact, flush with fresh water and seek medical assistance immediately. Contact with eyes may result
in irritation.
Use gloves when handling. In the event of skin contact, wash well with soapy water. Contact with skin
may cause a rash and discomfort.
Do not drink. If it is drunk by mistake, do not induce vomiting; make the affected person drink 1 to 2
cups of water and seek medical assistance immediately. If the affected person loses consciousness, do
not give the person anything by their mouth. If vomiting occurs naturally, tilt the body to prevent
inhalation.
After use, be sure to wash hands thoroughly.
Keep the container sealed to prevent foreign objects and moisture from getting inside, and store it in a
cool, dark area away from direct sunlight.
Keep out of reach of children.
Dispose of used oil, old oil, or oil used for cleaning in accordance with the method stipulated by the
law.
In order to maintain proper performance, it is recommended that you replace the oil after riding 1,000
km from the start of use, then after about once every year (or once about every 2,000 km if the bicycle
is used very frequently).
Do not use oil other than SG-S700 OIL. Problems such as an oil leakage and gear shifting malfunction
may occur.
Disposal of used oil: Follow local county and/or state codes for disposal. Use caution when preparing

Adding new oil
Push the piston to inject the new oil into the inside of the hub.

When the oil is forced in, the internal pressure will increase and the piston may push back. If the
piston is periodically pulled back to reduce the pressure inside the hub, the oil will be easier to
inject into the inside of the hub.

After pulling back the piston to reduce the internal pressure, remove the bleed nipple.
If the bleed nipple is removed without pulling back the piston, the oil may flow back into the
piston together with air due to the internal pressure and spill out of the piston.
