. Secure the cables to the frame so that they will not caught by the tire or
any other parts while pedaling.
. Always be sure to use the TL-EWo1 special tool to remove the cable

the paint on the lrame will not come off together with the tape when the
tape is peeled off at times such as when replacing the cabl6. Once the
tape has come off, replace it with new tape.
