TO ENSURE SAFETY

• If the total weight of the bicycle (bicycle + rider + luggage) is indicated on the product, the power modulator that controls an excessive

braking effect is built in.

Use the compatible brake lever together. If the total weight of the bicycle is heavier than the recommended range, braking may be

insufficient; if lighter, braking will be too effective and the wheel may be locked, which may cause you to fall off the bicycle.

The power modulator is not an anti-locking device of the wheel.

Be sure to also inform users of the following:

• If any of the following occur while using the brakes, stop riding immediately and ask the place of purchase to carry out inspection and repairs.

1) If an abnormal noise is heard when the brakes are applied

2) If the braking force is abnormally strong

3) If the braking force is abnormally weak

If 1) and 2) occur, the cause might be a lack of brake grease, so ask the place of purchase to grease the mechanism with special roller brake

grease.

If 2) or 3) occurs when using BR-C6060-F, the power modulator may be malfunctioning. Have it inspected/repaired at the place of purchase.

• If the brake is used frequently, the area around the brake may become hot. Do not

touch the area around the brake for at least 30 minutes after you finish riding the

bicycle.

• Avoid continuous application of the brakes when riding down long slopes, as this will cause the internal brake parts of the Shimano INTER M

brake system to become very hot, and this may weaken braking performance. It may also cause a reduction in the amount of brake grease

inside the brake, and this can lead to problems such as abnormally sudden braking. The design of the Shimano INTER M brake system has been

carried out based on standards such as ISO (4210) and DIN (79100-2). These standards specify the performance for an overall weight of 100 kg.

However, BR-C6000-F/C6060-F is designed with the overall weight assumed to be 130 kg. If the overall weight exceeds 100 kg (130 kg for

BR-C6000-F/C6060-F), the braking force provided by the system may be insufficient for correct braking, and durability of the system may also be

reduced.

• The front INTER M brake system should only be installed to the left side of a bicycle which is 26 inch" or larger.

If it is used on a bicycle which is smaller than 26 inch", the braking force may be too great, which could cause accidents.

• In order to get the best performance from the Shimano front INTER M brake, be sure to use Shimano brake cables and brake levers as a set.

(http://productinfo.shimano.com/lineupchart.html) (The amount of movement of the inner cable must be: 21.5 mm (when using BL-C6010) /

16.5 mm (when using BL-C6000 / BL-IM60 / BL-IM65 / BL-IM45) or more when the brake lever is pressed. If it is less than 21.5 mm / 16.5 mm,

braking performance will suffer, and the brakes may fail to work.)

• If the brake cable becomes rusted, braking performance will suffer. If this happens, replace the brake cable with a genuine Shimano brake

cable and re-check the braking performance.

• The brake unit and front hub unit should never be disassembled. If they are disassembled, they will no longer work properly.

• For BR-C6060-F, the power modulator is built into the brake body so a power modulator is not needed in the hub body. However, the special

front fork is needed to install it.

• Use a wheel with 3x or 4x spoke lacing. Cannot be used with wheels with radial lacing. Otherwise, the spokes or the wheel may be damaged,

or noise may occur when braking.

• The INTER M brake is different from conventional band brakes in that the inside of the brake drum is filled with grease, causing the turning of

the tire to be slightly heavier than usual. (Particularly in cold weather.)

• If you apply the front INTER M brake strongly while the bicycle is stopped and then shake the wheel, you will notice that there is a small

amount of gap in the brakes. This is normal, and will not cause any problems at all while riding.
