Important  Saftey  Information

• 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 fatl, which could lead to severe 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.

• 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.

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

• Keep the coin batteries out of the reach of children. If batteries are swallowed by mistake, seek medical attention immediately.

• Dispose of the coin batteries according to proper country and/or state disposal regulations.

• Disposal of this product into fire or a hot oven, or mechanically crushing or cutting it, can result in an explosion of the coin batteries.

• Do not use the coin batteries outside their 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 use the coin batteries 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 from the coin batteries gets on your skin or clothes, wash it off immediately with clean water. The leaked fluid may damage your skin.

• Do not leave this product in an extremely high temperature environment such as in a closed vehicle on a hot day, or near a heater. Doing so may result in an explosion of the coin batteries or the leakage of flammable liquid or gas from them.

• Do not subject this product to extremely low air pressure. Doing so may result in an explosion of the coin batteries or the leakage of flammable liquid or gas from them.

• Transporting this battery by air is not a problem.

• When operating the shift 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 bi 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.

• The braking force for a hydraulic brake system will increase along with the size of the disc brake rotor (140 mm, 160 mm, 180 mm, 203 mm).

• Do not use a 203 mm disc brake rotor. This will excessively increase the braking force, which could cause you to lose control of the bicycle, fall, and be seriously injured.

• Only use a 180 mm disc brake rotor if you are unable to obtain sufficient braking force with a 160 mm disc brake rotor upon a trial ride, such as when riding an electronic assist road bicycle or if the rider is heavy.

• Otherwise, you may lose control of the bicycle, fall, and be seriously injured.

• If you feel that the braking force is too high or too low, stop use and consult a place of purchase or a distributor. Acidents or falls may occur due to losing control of the bicycle, possibly resulting in serious injury.  force at the beginning of braking (higher than

• 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 use the brakes with fluid leaking. Doing otherwise 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 wil 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 lose traction; therefore, to avoid this, reduce your speed and apply the brakes early and gently. If the tires lose traction, you may fall and be seriously injured.

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 soapy water. Contact with skin may cause a rash and discomfort.
• 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.

Bed-in period

• Disc brakes have a bed-in period, and the braking force will gradually increase as the bed-in period progresses.
• Accidents or falls may occur due to losing control of the bicycle, possibly resulting in serious injury.
• The same thing will happen when the brake pads or disc brake rotor are replaced.

Regular inspections before riding the bicycle

• Before riding the bicycle, check the following items. If any problems are found, consult your place of purchase or a distributor.
• Are there any signs of brake oil leakage?
• Do the front and rear brakes work correctly?
• Do the pads have a thickness of 0.5 mm or more?
• Is the disc brake rotor cracked or deformed?
• Does gear shifting occur when the shift switches are operated?
• Are the levers securely installed to the handlebar?
• Do any abnormal noises ocur during operation?
• Is there sufficient charge remaining in the coin batteries?
