Place the pedal back in the socket and tighten it until it is secure.

To tighten the pedals, turn the right pedal clockwise and the left pedal counterclockwise.

Once you feel resistance, turn the pedal about 1/8 of a rotation further to properly tighten it.

DO NOT use excessive force when you are tightening the pedal. This can lead to difficulty removing the pedal in the future.
