•• Be sure to hold the power cable by the power plug when connecting and disconnecting the power plug from the electrical
outlet. If you do not hold the power cable by the power plug, fire or electric shocks may occur.
*If heat or acrid-smelling smoke is coming out from the power plug.
*There may be a bad connection inside the power plug.
•• Do not overload the electrical outlet with appliances beyond its rated capacity, and use only a 100 – 240 V AC electrical outlet.
If the electrical outlet is overloaded by connecting too many appliances using adapters, overheating resulting in fire may occur.
•• Do not damage the power cord or power plug. (Do not damage, process, forcibly bend, twist or pull them, bring them near hot
objects, place heavy objects on them or bundle them tightly together.) If they are used while damaged, fire, electric shocks or
short-circuits may occur.
•• Do not use the charger with commercially-available electrical transformers designed for overseas use, as they may damage the
charger.
•• Always be sure to insert the power plug as far as it will go. If this is not observed, fire may occur.
< SM-BCR2: Battery charger for SM-BTR2 >
•• Do not use any USB cable other than the USB cable which is supplied with the PC linkage device. This may cause a charge error,
fire, or failure of the connected PC due to heating.
•• Do not connect the charger to PC when it is on standby. This may cause a failure of PC depending on its specifications.
•• When connecting or disconnecting the USB cable or the charging cable, be sure to hold the plug of the cable. Failure to do so
may cause a fire or electric shock.
If the following symptoms are observed, stop using the device and contact a dealer. A fire or electric shock may be caused.
*If heat or acrid-smelling smoke is coming out from the power plug.
*There may be a bad connection inside the power plug.
•• If it thunders while charging with an AC adapter with a USB port, do not touch the device, bicycle, or the AC adapter. When
lightning strikes, an electric shock may be caused.
•• Use an AC adapter with a USB port with a voltage of 5.0 Vdc and with a current equal to or higher than 1.0 Adc. If the one
with a current lower than 1.0 Adc is used, a charge error may occur or the AC adapter may heat up, leading to a fire.
•• Do not use a USB hub when connecting the cable to a PC USB port. This may cause a charge error or fire due to heating.
•• Be careful not to damage the charging cable. (Do not damage, process, forcibly bend, twist or pull them, bring them near hot
objects, place heavy objects on them or bundle them tightly together.) If they are used while damaged, fire, electric shocks or
short-circuits may occur.
< Brake >
•• 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 a fall, which could lead to severe injury. Because each bicycle may handle differently,
be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation
of your bicycle. This can be done by consulting your professional bicycle dealer and the bicycle's owners manual, and by
practicing your riding and braking technique.
•• If the front brake is applied too strongly, the wheel may lock and the bicycle may fall forward, and serious injury may result.
•• Always make sure that the front and rear brakes are working correctly before you ride the bicycle.
•• The required braking distance will be longer during wet weather. Reduce your speed and apply the brakes early and gently.
•• If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off the bicycle. To avoid this, reduce your
speed and apply the brakes early and gently.
7
< Disc brake >
•• 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.
•• The calipers and disc brake rotor will become hot when the brakes are operated, so do not touch them while riding or
immediately after dismounting from the bicycle, otherwise you may get burned.
•• Be careful not to allow any oil or grease to get onto the disc brake rotor and brake pads, otherwise the brakes may not work
correctly.
•• If any oil or grease does get on the pads, you should consult a dealer or an agency. There is the danger that the brakes may not
work correctly.
•• If noise occurs during brake operation, the pads may have been worn down to the usable
limit. Check that the brake system temperature has been cooled down sufficiently, and
then check that the thickness of each pad is 0.5 mm or more. Or, consult a dealer or an
agency.
2 mm
0.5 mm
•• If the disc brake rotor is cracked or deformed, immediately stop using the brakes and consult a dealer or an agency.
•• If the disc brake rotor becomes worn down to a thickness of 1.5 mm or less, or if the aluminum surface appears, immediately
stop using the brakes and consult a dealer or an agency. The disc brake rotor may break, and you may fall off the bicycle.
For Installation to the Bicycle, and Maintenance:
•• When installing the hub to the frame, install the specified non-turn washer to both the left and right sides, and securely
tighten the hub nut to the specified torque. If the non-turn washer is installed only on one side or the hub nut is not fully
tightened, the non-turn washer may come off, causing the hub axle and the motor unit to turn, which in turn may cause the
electric wire to be disconnected or damage the motor unit.
•• Assemble the wheel with 3x or 4x spoke lacing. Do not spoke the wheel radially. Otherwise, the spokes or the wheel may be
damaged, or noise may occur when braking.
< SG-S705 >
•• For SG-S705, be sure to insert a rotor spacer when installing the disc brake rotor. Otherwise, the disc brake rotor may rattle,
causing noise or braking failure.
8
CAUTION
Be sure to also inform users of the following:
< SM-BCR1: Battery charger for SM-BTR1 >
•• Disconnect the power plug from the electrical outlet before cleaning the charger.
< SM-BCR2: Battery charger for SM-BTR2 >
•• Disconnect the USB cable or the charging cable when performing maintenance.
< Lithium Ion Battery >
•• Store the battery in a safe place away from the reach of infants and pets.
< SM-BTR1: Lithium ion battery (external type) >
•• If not using the battery for long periods, remove it and store it away in a safe place.
< SM-BTR2: Lithium ion battery (built-in type) >
•• If the unit will not be used for an extended period, store it after charging in cool indoor places (approx. 10 to 20 °C) where the
battery will not be exposed to direct sunlight or rain.
< Disc brake >
•• Disc brakes have a burn-in period, and the braking force will gradually increase as the burn-in period progresses. Make sure
that you are aware of any such increases in braking force when using the brakes during the burn-in period. The same thing will
happen when the brake pads or disc brake rotor are replaced.
NOTE
Be sure to also inform users of the following:
•• Be sure to rotate the crank when carrying out any switch operations which are related to gear shifting.
•• This is a small waterproof connector. Do not repeat connecting and disconnecting it. It may impair the function.
•• Be careful not to let water get into the terminal.
•• The components are designed to be fully waterproofed to withstand wet weather riding conditions; however, do not
deliberately place them into water.
•• Do not clean the bicycle in a high-pressure car wash. If water gets into any of the components, operating problems or rusting
may result.
•• Handle the products carefully, and avoid subjecting them to any strong shocks.
•• Do not use thinners or similar substances to clean the products. Such substances may damage the surfaces.
•• Contact the place of purchase for updates of the product software. The most up-to-date information is available on the
Shimano website.
•• 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.

< SG-S705 / SG-S505 >
•• The internal geared hub is not completely waterproof. Avoid using the hub in places where water might get inside it and do
not use high-pressure water to clean the hub, otherwise the internal mechanism may rust.
•• 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 internal geared hub has a built-in mechanism to support shifting. When this support mechanism operates during shifting,
noise or vibration may occur. The shifting feel may also change depending on the gear position at the time of shifting.
Noise may also be produced in the 5 to 8th gear for SG-S505 and 7 to 11th gear for SG-S705 if the crank arms are turned
backward or if the bicycle is pushed backward.
These occurrences are a normal result of the structure of the internal gear shifting mechanism, and are not a sign of a
malfunction.
< Battery charger / Battery charger cord >
•• Use this instrument under the direction of a safety supervisor or the direction for use. Do not allow physically, sensory, or
mentally impaired persons, inexperienced persons, or persons with no required knowledge including children to use this

disposing.
< Lithium ion battery >
•• Lithium ion batteries are recyclable, valuable resources.
For information on used batteries, contact the place of purchase or a bicycle dealer.
•• Charging can be carried out at any time regardless of the amount of charge remaining. Always be sure to use the special
battery charger to charge the battery until it is fully recharged.
•• The battery is uncharged at the time of purchase. Before riding, be sure to charge the battery until it is fully charged.
•• If the battery has become fully spent, charge it as soon as possible. If you leave the battery without charging it, it will cause
the battery to deteriorate.
•• The battery is a consumable item. The battery will gradually lose its capacity for charging after repeated use and after time has
passed. If the length of time that the battery can be used becomes extremely short, it has probably reached the end of its life,
and so you will need to purchase a new battery.
•• The life of the battery will vary depending on factors such as the storage method, the usage conditions, the surrounding
environment and the characteristics of the individual battery pack.
•• If storing the battery away for a long period, remove it when the battery level is 50% or higher or when the green indicator is
illuminating in order to prolong its useful life. It is recommended that you charge the battery about once every half a year.
•• If the storage temperature is high, the performance of the battery is reduced, and its available time will be shorter. When you
use the battery after a long storage period, store the battery indoors where the battery will not be exposed to direct sunlight
or rain.
•• If the ambient temperature is low, the available time of the battery will be shorter.
10
< SM-BTR1: Lithium ion battery (external type) >
•• When storing the battery away, remove the battery from the bicycle and install the terminal cover first.
•• The charging time is approximately 1.5 hours. (Note that the actual time will vary depending on the amount of charge
remaining in the battery.)
•• If the battery feels difficult to insert or remove, apply specified grease (premium grease) to the part that touches the O-ring at
the side.
< SM-BTR2: Lithium ion battery (built-in type) >
•• After removing the battery from the bicycle for storage, install a dummy plug.
•• The charging time of an AC adapter with a USB port is about 1.5 hours, and that of computer USB port type about 3 hours.
(Note that the actual time will vary depending on the amount of charge remaining in the battery. Depending on the
specifications of the AC adapter, recharging via the AC adapter requires as many hours (about 3 hours) as recharging via PC.)
< Battery charger / Battery charger cord>
•• Charge the battery in indoor places to avoid exposure to rain or wind.
•• Do not use outdoors or in environments with high humidity.
•• Do not place the PC linkage device on dusty floors when using it.

•• Do not apply excessive tension to the cables.
•• Do not wash the PC linkage device or wipe it using detergents.
•• Use this instrument under the direction of a safety supervisor or the direction for use. Do not allow physically, sensory, or
mentally impaired persons, inexperienced persons, or persons with no required knowledge including children to use this
instrument.
•• Do not allow children to play near this instrument.
< SM-BCR2 : Battery charger for SM-BTR2 >
•• Connect the PC linkage device directly to a computer, without using an intermediate device such as a USB hub.
•• Do not ride the bicycle while the PC linkage device and cable are still connected to it.
•• Do not connect two or more of the same units to the same connection point. If this is not done, the units may not operate
correctly.
•• Do not connect or disconnect units again while unit recognition is in progress or after recognition is complete. If this is not
done, the units may not operate correctly.
Check the procedures which are given in the user's manual for the E-tube Project when connecting and disconnecting units.
•• The tightness of the PC link cable will tend to drop after repeated connections and disconnections. If this happens, replace the
cable.
•• Do not connect two or more PC linkage device at the same time. If two or more PC linkage device units are connected, they will
not operate correctly. In addition, operating errors may occur at the PC and it may require the PC to be restarted.
•• PC linkage devices cannot be used while the charger is connected.
11
For Installation to the Bicycle, and Maintenance:
•• Be sure to attach dummy plugs to any unused terminals.
•• Always be sure to use the TL-EW02 special tool to remove the electric wires.
•• The motor unit cannot be disassembled for repair.
•• Contact Shimano for information regarding the shipment of the battery charger to South Korea and Malaysia.
•• You should periodically wash the chainrings in a neutral detergent. In addition, cleaning the chain with neutral detergent and
lubricating it can be an effective way of extending the useful life of the chainrings and the chain.
•• If chain skipping has started occurring, replace the gears and the chain at a dealer or an agency.
< Internal geared hub >

•• In order to maintain proper performance, it is recommended that you contact the place of purchase or a bicycle dealer to carry
out maintenance such as internal oil replacement after riding 1,000 km from the start of use and after that, about once every
two years (or once about every 5,000 km if the bicycle is used very frequently).
< SG-S705 >
•• 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 gear shifting malfunction may occur.
< SG-S505 >
•• When you perform oil maintenance, use the WB maintenance oil or the WB maintenance oil set.
If the WB maintenance oil is not used, problems such as an oil leakage and gear shifting malfunction may occur.
12
< Electric wires / Electric wire covers >
•• Secure the electric wires with zip ties so that they do not interfere with the chainrings, sprockets and tires.
•• The strength of the adhesive is fairly weak, to prevent the paint on the frame from being peeled off at the same time when
removing the electric wire cover for reasons such as replacing the electric wires. If the electric wire cover is peeled off, replace
it with a new one. When removing the electric wire cover, do not peel it off too vigorously. If this is not observed, the paint on
the frame will peel off too.
•• Do not remove the wire holders which are attached to the built-in type electric wires (EW-SD50-I). The wire holders prevent the
electric wires from moving inside the frame.
< Dual control lever >
•• Dummy plugs are installed at the time of shipment from the factory. Do not remove them except when necessary.
•• When routing the electric wires, take care to ensure that they do not interfere with the brake levers.
< SM-BMR1 / Battery mount >
•• This is supported by the firmware versions 2.0.0 and later.
The actual product may differ from the illustration because this manual is intended chiefly to explain the procedures for
using the product.

General Safety Information
WARNING
••When changing the oil, be careful that no oil gets on the disc brake rotor, brake 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 by mistake, go immediately to an area with fresh air. Stay warm and quiet, and seek professional
medical advice if required. If breathing stops, perform artificial respiration, and if breathing is difficult, provide the affected
person with oxygen.
Cautions regarding handling of SG-S700 Oil :
••Use safety glasses when handling, and avoid contact with eyes. Contact with eyes may result in irritation.
In the event of eye contact, flush with fresh water and seek medical assistance immediately.
••Use gloves when handling. Contact with skin may cause a rash and discomfort.
In the event of skin contact, wash well with soap and water.
If skin condition becomes abnormal, seek medical assistance immediately.
••Do not drink the oil. 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.
••When storing, close the container tightly to prevent water or foreign materials from entering. Store out of reach of children. Do
not store in areas subject to direct sunlight, areas subject to temperatures above 40ºC, areas subject to water or high humidity
where rust is likely to occur, or in areas where there is a risk of freezing.
••Dispose of used oil, old oil, or oil used for cleaning in accordance with applicable local laws and regulations.
••To maintain product performance, oil should be changed after the first 1,000 km from start of use of the product, and once every
2 years thereafter (after every 5,000 km if bicycle is ridden frequently).
••When performing maintenance, use only Shimano SG-S700 OIL. Use of other oils may cause problems such as oil leakage, faulty
operation of speed changer, etc.
••When using a 1L can of oil, it may become impossible to suck out oil with a syringe when there is only a little oil left. First,
transfer all oil to a different container.
••Read these instructions carefully, and keep them in a safe place for later reference.
