TO ENSURE SAFETY
„
Disc brake
• Keep your fingers away from rotating disc brake rotors. Disc brake rotors are sharp enough to severely injure your
fingers if caught within the openings of a disc brake 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.
• Do not 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.
• 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 due to a fall or collision.
0.5 mm 2 mm
• 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 or collision.
• 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 or collision.
For Installation to the Bicycle, and Maintenance:
• When installing the hub to the frame, be sure to install the correct non-turn washers to the left and right sides, and securely tighten the hub nuts to
the specified torques. If the non-turn washer is installed only on one side or the hub nut is not fully tightened, the non-turn washer may come off,
causing the hub axle and the motor unit to turn, which in turn may cause the electric wire to be disconnected or damage the motor unit.
• Assemble the wheel with 3x or 4x lacing, and do not spoke the wheel radially.
Otherwise, the spokes or the wheel may get damaged, or noise may occur when braking.
