WARNING
For assistance with installation, adjustment, and replacement of products not found in the user manual, please consult the place of purchase or a distributor. A dealer's manual for professional and experienced bicycle mechanics is available on our website (https://si.shimano.com).
For safety, be sure to carefully read this "user manual" before use, follow it for correct use, and save it so that you can refer back to it at any time.
The following instructions should always be followed in order to prevent personal injury, physical damage to equipment and the surrounding area. The instructions are classified according to the degree of danger or damage that may occur if the product is used incorrectly.
DANGER - Failure to follow the instructions will result in death or serious injury.
WARNING - Failure to follow the instructions could result in death or serious injury.
CAUTION - Failure to follow the instructions could result in personal injury or physical damage to equipment and the surrounding area.

For items requiring replacement, please consult the place of purchase or a distributor.
Be sure to observe the following instructions in order to prevent burns and other injuries due to fluid leakage, overheating, fire or explosion.

DANGER
- Use the specified charging cable when charging the battery. Using any other item may lead to fire, overheating, leakage, or damage to the connected PC.
- Prevent the charging cable from getting wet, and do not touch or hold it when it is wet or if your hands are wet. Failure to do so may result in operational problems or electric shock.
- Use an AC adapter with a USB port with a voltage of 5.0 V DC and a current rating of at least 1.0 A DC. If you use an adapter with a current rating of less than 1.0 A, the AC adapter may heat up and cause fire, smoke, overheating, damage, electric shock, or burns.
- Do not heat the battery or expose it to fire. Failure to do so may cause the battery to ignite or burst.
- Do not use or leave the battery in hot or humid places where the battery may be exposed to direct sunlight, in a closed vehicle on a hot day, or near a heater. Failure to do so may result in leakage, overheating, or bursting, which may cause fire, burns, or other injuries.
- Do not deform, modify, or disassemble the battery. Also, do not directly apply solder to the battery terminals. Failure to do so may result in leakage, overheating, or bursting, which may cause fire, burns, or other injuries.
- Do not allow metal terminals to come into contact with metal objects such as hairpins. Failure to do so may result in short circuits, overheating, burns, or other injuries.

WARNING
- Do not disassemble or modify the product. This may cause the product to not operate correctly, and you may fall unexpectedly and suffer serious injury.
- Always grasp the cable plug when connecting or disconnecting the USB cable or charging cable. Failure to do so may result in fire or electric shock.
- If the following symptoms occur, stop using the device and contact the place of purchase. Fire or electric shock may occur.
- If pungent smoke comes out of the AC adapter plug or the plug is hot. There may be a poor connection inside the AC adapter plug.
- If thunder is heard during charging with the AC adapter with USB port, do not touch the device, bicycle, or AC adapter. Electric shock may occur due to lightning strike.
- Do not use a USB hub to connect the cable to the PC's USB port. Charging failure or fire due to overheating may occur.
- Be careful not to damage the charging cable. Do not damage it, modify it, forcibly bend, twist, or pull it, place it near hot objects, place heavy objects on it, or tightly bundle it. Using it in a damaged state may result in fire, electric shock, or short circuit.
- If the battery is not fully charged after 4 hours of charging, stop charging. Failure to do so may result in fire, bursting, ignition, or overheating.
- Do not immerse the product in fresh or salt water, and prevent the terminals from getting wet. Failure to do so may result in fire, bursting, ignition, or overheating.
- Do not subject the product to strong impact or throw it. Failure to do so may result in bursting, overheating, or operational problems.
- Do not use the battery if it exhibits fluid leakage, discoloration, deformation, or other abnormal signs. Failure to do so may result in bursting, overheating, or operational problems.
- Clean the chain and QUICK-LINK regularly with an appropriate chain cleaner. Maintenance intervals depend on usage and riding circumstances. Never use alkali or acid-based solvents such as rust removers. If such a solvent is used, the chain or QUICK-LINK may break and cause serious injury.
- Check the chain for damage (deformation or cracking), skipping, or any other abnormalities such as erratic shifting. If any problems are found, consult the 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 prevent accidental swallowing.
- Prevent grease from adhering to the metal terminals. This may cause conduction failure.
- Do not leave the charging cable connected during maintenance.
