2)Take out the pedals, you will find that the pedals are marked with "L"
and "R". First put two drops of anti-loose fluid on the thread of the "R"
pedal, and then insert it into the threaded hole of the right crank, and turn it
clockwise until it stops, and then lock it with an open spanner. Take out the
"L" pedal, and put two drops of anti-loose fluid on the thread, and insert it
into the threaded hole of the left crank, turn it counterclockwise until it
stops, and then lock it with an open spanner.
(Note: The crank is also marked with "L" and "R" corresponding to the
markings on the pedals. If installed reversely, the slippage of the crank may
damage the product. Besides, the pedals must be locked, otherwise the
pedals may fall off after being used for a long time.)
