DANGER

WARNING

CAUTION

Failure to follow the instructions will result in death or serious injury.

Failure to follow the instructions could result in death or serious injury.

Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings.

Important safety information

Consult your place of purchase or a distributor regarding items requiring replacement.

Be sure to observe the following instructions in order to avoid burns or other injury from fluid leakage, overheating, fire, or explosion.

DANGER

• Use the dedicated charging cable when charging the battery. If any non-specified items are used, fire, overheating, leakage, or damage to the connected PC may occur.

• Do not get the charging cable wet and do not touch or hold it while it is wet or with wet hands. If this is not observed, problems with operation or electric shocks may occur.

• Use an AC adapter with a USB port that has a voltage of 5.0 V DC and a current equal to or higher than 1.0 A DC. If the one with a current lower than 1.0 A is used, the AC adapter may heat up, potentially causing a fire, smoke, overheating, destruction, electric shock, or burns.

• Do not heat the battery or expose it to flames. If this is not observed, combustion or bursting of the battery may occur.

• Do not use or leave the battery in hot and humid places such as where the battery is exposed to direct sunlight, in a closed vehicle on a hot day, or near a heater. If this is not observed, leakages, overheating or bursting may cause fire, burns or other injury to occur.

• Do not deform, modify, disassemble, or apply solder directly to the battery. If this is not observed, leakages, overheating or bursting may cause fire, burns or other injury to occur.

• Do not touch the metal terminals with metal items such as hairpins. If this is not observed, short-circuits, overheating, burns or other injuries may occur.

WARNING

• 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.

• When connecting or disconnecting the USB cable or the charging cable, be sure to hold the cable by the plug. Failure to do so may cause a fire or electric shock.

• If the following symptoms are observed, stop using the device and contact your place of purchase. A fire or electric shock may be caused.

– If heat, acrid-smell, or 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. If lightning strikes, electric shocks may occur.

• Do not use a USB hub when connecting the cable to a PC USB port. This may cause a charging error or fire due to overheating.

• Be careful not to damage the charging cable. Do not damage, modify, forcibly bend, twist or pull it, put it near hot objects, place heavy objects on it or bundle it tightly together. If it is used while damaged, fire, electric shocks or short-circuits may occur.

• If the battery does not become fully charged after 4 hours of charging, stop charging. If this is not observed, fire, bursting, ignition, or overheating may occur.

• Do not place this product in water or sea water, and do not allow the terminals to get wet. If this is not observed, fire, bursting, ignition, or overheating may occur.

• Do not throw or subject this product to strong shocks. If this is not observed, bursting, overheating or problems with operation may occur.

• Do not use the battery if leakages, discoloration, deformation or any other abnormalities occur. If this is not observed, bursting, overheating or problems with operation may occur.

• Clean the chain and QUICK-LINK with an appropriate chain cleaner regularly. Intervals between maintenance depend on the use and riding circumstances. Never use alkali-based or acid-based solvents such as rust cleaners. If those solvents are used the chain or QUICK-LINK might break and cause serious injury.

• Check the chain for any damage (deformation or cracking), skipping, or other abnormalities such as unintended gear shifting. If any problems are found, consult your place of purchase or a distributor. The chain may break, and you may fall.

CAUTION

• Store in a safe place out of the reach of small children to avoid letting them swallow by mistake.

• Do not let grease adhere to the metal terminals. A conduction failure may result.

• Do not leave the charging cable connected when performing maintenance.

Notice

• The gears should be periodically washed with a neutral detergent then lubricated. In addition, cleaning the chain and QUICK-LINK with a neutral detergent and lubricating them can be an effective way of extending the life of the chain and QUICK-LINK.

• Do not use the thinners or harsh solvents to clean the products. Such substances may damage the surface.

• If gear shifting operation does not feel smooth, consult the place of purchase for assistance.

• If the chain keeps skipping during use, replace the gears and chain at the place of purchase.

• If there is a large amount of excess play in the pulleys and extra noise is generated while riding, replace the pulleys at your place of purchase.

• The electric wire has small waterproof connectors, so do not repeatedly connect and disconnect it too often. Doing so may impair the waterproofing.

• 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 wash. If water gets into any of the components, operating problems or rusting may result.

• Contact the place of purchase for updates of the component software.

The most up-to-date information is available on the SHIMANO website.

• Do not get the charging cable or charging port wet when connecting them.

• Be careful not to get water into the E-TUBE ports.

• Handle the components carefully, and avoid subjecting them to strong shock.

• Disconnect the Bluetooth LE connection when not using E-TUBE

PROJECT for smartphones/tablets. The rear derailleur does not shift gears when connected over Bluetooth LE.
