Warnings and instructions

WARNING
For information on installation, adjustment, and replacement of the products which are not found in the user's 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 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 instructions should always be followed in order to prevent personal injury, physical damage to equipment and the surroundings. The instructions are classified according to the degree of danger or damage which 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 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 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 modify the product. It may cause the product to not operate correctly, and you may unexpectedly fall and be seriously injured.
- Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may topple forward, and serious injury may result.
- 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 crash 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 do happen to lose traction, you may fall and be seriously injured.
- Do not allow any oil or grease to get onto the brake shoes. If the bicycle is ridden with oil or grease on the brake shoes, the brakes may not work correctly, and serious injury could result due to a fall or collision.
- Do not use the brake cable if it is rusty, frayed, or cracked. Otherwise, the brakes may not work correctly.
