Warnings and instructions

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

For items that require replacement, be sure to consult the place of purchase or a distributor.
Be sure to observe the following directions 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. Use of 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 problems with operation or electric shock.
- Use an AC adapter with a USB port with a voltage of DC 5.0 V and a current rating of at least DC 1.0 A. If you use an adapter with a current rating of less than 1.0 A, the AC adapter may heat up, and fire, smoking, overheating, damage, electric shock, or burns may occur.
- Do not heat the battery or expose it to flame. Failure to do so may result in the battery igniting or bursting.
- Do not use or leave the battery in hot or humid locations 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 result in 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 result in 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-circuiting, 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 a pungent smoke is emitted from the AC plug or the AC plug is hot. There may be a poor connection inside the AC 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 together. If it is used in a damaged state, fire, electric shock, or short-circuiting may occur.
- 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 problems during operation.
- 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 problems during operation.
- 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 that the chain is not damaged (deformation or cracking), skipping, or exhibiting 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.
