com).

• Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer.

For safety, be sure to read this “user's manual” thoroughly before use, follow it for correct use, and store it so that it can be referenced at any time.

Important safety information

WARNING

• Because each bicycle may handle slightly differently depending on the model, be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your bicycle. Improper use of your bicycle's brake system may result in a loss of control or a fall, which could lead to serious injury.

• Do not disassemble or modify the product. This may cause the product to not operate correctly, and you may suddenly fall and be seriously injured.

• Use only the battery specified. Using an incorrect battery may cause the battery to burst or leak fluid, resulting in fire, injury, or defacement in the surrounding area.

• Do not use the battery outside its operating temperature ranges. If the battery is used or stored in temperatures which are outside these ranges, fire, injury or problems with operation may occur.

• Do not throw or subject this product to strong shocks. If this is not observed, bursting, overheating or problems with operation may occur.

• Do not let grease adhere to the metal terminals. A conduction failure may result.

• Do not use the battery if leakages, discoloration, deformation or any other abnormalities occur. If this is not observed, bursting, overheating or problems with operation may occur.

• If any leaked fluid gets on your skin or clothes, wash it off immediately with clean water. The leaked fluid may damage your skin.

• Store in a safe place out of the reach of small children to avoid letting them swallow by mistake.

• Keep used batteries out of the reach of children, and dispose of them in accordance with local waste regulations. If batteries are swallowed by mistake, seek medical attention immediately.

• When operating the shifting switch, be careful not to allow your fingers to be caught in the derailleur. The powerful motor which drives the electronic gear shifting derailleur will operate without stopping until the shifting position is reached.

• This hydraulic brake system has different braking characteristics from those of the rim brake type, demonstrating relatively high braking force at the beginning of braking (higher than the rim brake type); familiarize yourself sufficiently with the braking characteristics before using it. If you ride the bicycle without becoming sufficiently familiar with the braking characteristics, braking may cause you to fall off the bicycle, potentially causing serious injury or a fatal accident.

• Riders must become accustomed to the higher performance of this brake before riding the bicycle. Using larger diameter disc brake rotors provides a higher braking force than smaller diameter disc brake rotors. If you ride the bicycle without becoming sufficiently familiar with the braking characteristics, braking may cause you to fall off the bicycle, potentially causing serious injury or a fatal accident.

• Please use extra caution to keep your fingers away from the rotating disc brake rotor. The disc brake rotor is sharp enough to inflict severe injury to your fingers if caught within the openings of moving rotor.

• Do not touch the calipers or disc brake rotor while riding or immediately after dismounting from the bicycle. The calipers and disc brake rotor will become hot when the brakes are operated, so you may get burned if you touch them.

• Be careful not to allow any oil or grease to get onto the disc brake rotor and brake pads. Riding the bicycle with oil or grease on the disc brake rotor and brake pads may prevent the brakes from operating and result in serious injury due to a fall or collision.

2 mm 0.5 mm • Check the thickness of the brake pads and do not use them if they have a thickness of 0.5 mm or less.

Doing so may prevent the brakes from operating and result in serious injury.

• Do not use the disc brake rotor if it is cracked or deformed. The disc brake rotor may break, and result in serious injury due to a fall.

• Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also do not use it if the aluminum surface becomes visible. The disc brake rotor may break, and result in serious injury due to a fall.

• Do not continuously apply the brakes. Doing so may cause a sudden increase in the brake lever stroke, preventing the brakes from operating and resulting in serious injury.

• Do not use the brakes with fluid leaking. Doing so may prevent the brakes from operating and result in serious injury.

• Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may fall forward, and serious injury may result.

• Because the required braking distance will be longer during wet weather, reduce your speed and apply the brakes early and gently.

You may fall or collide and be seriously injured.

• A wet road surface may cause tires to skid; to avoid this, reduce your speed and apply the brakes early and gently. If the tires skid, you may fall and be seriously injured.

• Do not use or leave the unit in hot and humid places such as where the unit is exposed to direct sunlight, in a closed vehicle on a hot day, or near a heater. If this is not observed, leakages of flammable liquid or gas, overheating or bursting may cause fire, burns or other injury to occur.

• Do not subject this product to extremely low air pressure. That may result in an explosion of incorporated battery or the leakage of flammable liquid or gas from it. Transporting this product by air is not a problem.

• Observe all federal, state and local environmental regulations when disposing of this product, because it has a built-in battery in addition to its button battery. Disposal of this product into fire or a hot oven, or mechanically crushing or cutting of it, can result in an explosion of the built-in battery.

CAUTION

„ Cautions on SHIMANO genuine mineral oil

• In the event of eye contact, flush with fresh water and seek medical assistance immediately.

Contact with eyes may result in irritation.

• In the event of skin contact, wash well with soap and water.

Contact with eyes may result in irritation.

• Cover nose and mouth with a respirator type mask and use in a well ventilated area. Inhalation of mineral oil mist or vapors may cause nausea.

• If mineral oil mist or vapor is inhaled, go immediately to an area with fresh air. Cover up with a blanket. Stay warm and stable and seek professional medical advice.

„ Burn-in period

• Disc brakes have a burn-in period, and the braking force will gradually increase as the burn-in period progresses. Make sure that you are aware of any such increases in braking force when using the brakes during the burn-in period. The same thing will happen when the brake pads or disc brake rotor are replaced.

• Use soapy water or a dry cloth when cleaning and carrying out maintenance of the brake system. Do not use commercially available brake cleaners or silencing agents. Such substances can cause damage to parts such as seals.

• Contact the place of purchase for updates to the component software.

The most up-to-date information is available on the SHIMANO website.

• Also read the manuals for other connected components together with the manual for the brakes.

• Be sure to attach dummy plugs to any unused E-TUBE ports and the satellite shifter connection port. If water gets into any of the components, operating problems or rusting may result.

• The electric wire has small waterproof connectors, so do not repeatedly connect and disconnect it too often. It may impair the function.
