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:
•
Never use alkali- or acid-based solvents such as rust cleaners. If those solvents are used the chain might break and cause serious injury.
•
Clean the chain with an appropriate chain cleaner regularly. Intervals between maintenance depend on the use and riding circumstances.
•
Check that the wheels are fastened securely before riding the bicycle. You may fall or collide and be seriously injured.
•
Check the chain for any damage (deformation or cracking), skipping, or other abnormalities such as unintended gear shifting. The chain may break,
and you may fall.
•
Do not disassemble or modify the product. This may cause the product to not operate correctly, and you may suddenly fall and be seriously injured.
Motor Unit
•
Never place your foot on the motor unit. This may cause the product to not operate correctly, and you may suddenly fall and be seriously injured.
Brake
•
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.
•
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, it may result in serious injury due to a fall or collision.
For Installation to the Bicycle, and Maintenance:
•
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 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 lacing, and do not spoke the wheel radially. Otherwise, the spokes or the wheel may get damaged, or noise may
occur when braking.
Disc brake
•
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.
4
Page 5
TO ENSURE SAFETY
•
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 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 or collision.
•
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 or collision.
Coaster brake
•
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.
Coaster brake hub
•
When using a reversed rear dropout, use a chain adjuster to remove excess slack from the chain.
CAUTION
0.5 mm2 mm
Be sure to also inform users of the following:
Disc brake
•
To optimize the performance of the brake pads and disc brake rotor, perform the bed-in procedure as explained in the steps below:
1. Ride your bicycle in a flat and safe area without obstacles and accelerate to a moderate speed.
2. Operate the brake lever until you slow down to walking speed.
Perform this operation carefully with only one brake lever at a time. Always operate your brake lever with moderation, especially when you bed in
the front brake.
3. Repeat steps 1 and 2 for at least 20 times for both the front and rear brakes.
While repeating the process, the brake force will increase.
Coaster brake
•
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
•
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.
Area around the brake
•
Do not continuously apply the brakes when riding down long slopes. Doing so 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.
•
The brake unit and front hub unit should never be disassembled. If it is disassembled, it may no longer work properly.

TO ENSURE SAFETY
NOTICE
Be sure to also inform users of the following:
•
Do not keep connecting and disconnecting the small waterproof connector. Doing so may impair the waterproofing.
•
Be careful not to get water into the E-TUBE port.
•
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 with a high-pressure washer. If water gets into any of the components, operating problems or rusting may result.
•
Handle the product carefully, and avoid subjecting it to any strong shocks.
•
Do not use the thinners or harsh solvents to clean the products. Such substances may damage the surfaces.
•
The most up-to-date information on software for this product is available on the SHIMANO website.
•
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.
•
All of the following occurrences are due to the internal gear-shifting structure and are not the failure of the internal components.
Type of hub
Phenomenon
Noise occurs when the pedals rotate. × - All gear positions except 1st
Noise occurs when the bicycle is pushed backward. × × All gear positions except 1st
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. × × All gear positions
Noise occurs when pedal rotation is stopped during riding. × - All gear positions
•
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.
PC linkage device
•
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 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, the PC may need to be restarted if operating errors occur.
•
PC linkage devices cannot be used while the charger is connected.

TO ENSURE SAFETY
Internal geared hub
•
In order to maintain proper performance, it is recommended that you lubricate the internal unit once a year from the start of use (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, it is
recommended to use SHIMANO internal geared hub grease or a lubrication kit for the maintenance. If SHIMANO grease or a SHIMANO lubrication kit
is not used, problems such as a malfunction in the shifting unit may occur.
Coaster brake specifications
•
If the wheels are not rotating smoothly, you need to replace or grease the brake shoes.

General Safety Information
WARNING
•
When lubricating the internal unit, 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.
Cautions regarding handling of WB maintenance oil:
•
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 once a year from the start of use (or once about every 2,000 km if
the bicycle is used very frequently).
•
Do not use oil other than WB maintenance 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 the oil for disposal.
•
Read this manual carefully, and keep it in a safe place for later reference.
