WARNING
For assistance with installation, adjustment and replacement of the products which are not found in the user's manual, please contact 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's manual" 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 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 or surroundings.
WARNING
- Because each bicycle may handle differently depending on the model, learn the proper braking technique (including pressure on the brake lever and bicycle control characteristics) and 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 alter the product. It may cause the product to not operate correctly, and you may fall unexpectedly and be seriously injured.
- When operating the shift switch, be careful that your fingers do not get caught in the derailleur. The powerful motor that drives the electronic shift derailleur will run without stopping until the shift 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, and this may cause a 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.
- Wet road surfaces may cause the 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.
