Warnings and instructions

WARNING
For installation, adjustment and replacement information about products not found in the user's manual, 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 surroundings. The directions are classified according to the degree of danger or damage which 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 cause personal injury or physical damage to equipment and surroundings.

WARNING
- Because each bicycle may handle slightly differently depending on the model, learn the proper braking technique (including pressure on the brake lever and bicycle handling characteristics) and the operation of your bicycle. Improper use of the bicycle's brake system may result in a loss of control or fall, which could lead to serious injury.
- Do not disassemble or modify the product. It may cause the product to not operate correctly, and you may fall unexpectedly and be seriously injured.
- When operating the shifting switch, be careful not to get your fingers caught in the derailleur. The powerful motor that drives the electronic shifting derailleur will run without stopping until the shifting position is reached.
- Do not apply the front brake too strongly. If you do, the front wheel may lock and the bicycle may fall forward, causing serious injury.
- Because the required braking distance will be longer during wet weather, reduce your speed. Apply the brakes well in advance and gently. You may fall or collide and be seriously injured.
- A wet road surface can cause tires to lose traction. To avoid this, reduce your speed and apply the brakes well in advance and gently. If the tires lose traction, you may fall and be seriously injured.
