STEP 4. Be very careful in securing pedals to the pedal cranks. Otherwise, pedals
and crank threads can easily become stripped and must be replaced. Note
that left and right side designations refer to the user's left and right sides,
as the person exercises on the bike. Put the pedal marked "R" on the right
crank fitting. Turn the pedal stem clockwise by hand until you feel it
smoothly thread into place. Then use the pedal wrench to secure the pedal
firmly on the crank. Put the pedal marked "L" on the left crank. Turn the
pedal stem counterclockwise by hand until you feel it smoothly thread into
place. Then use the pedal wrench to secure it firmly in place on the crank.
