HOW TO ADJUST THE CHAIN If there is slack in the chain or if the chain makes a slapping sound while you are pedaling, the chain may need to be adjusted. To adjust the chain, rst rotate the Right Crank Arm (31) to the position shown. Then, turn the Right Pedal (35) counterclockwise and remove it. Note: Only one side of the Flywheel (36) is shown in the drawings below. Loosen the 5/16" Nuts (63), one on each side of the Flywheel (36). 28 6 31 56 63 58 14 35 36 Next, see the EXPLODED DRAWING on page 23 and remove all the Screws (51, 52) from the Chain Guard Cover (15); make sure to note which size 1" Screws come from which holes. Then, see the drawing above and remove the #8 x 1 1/2" Screw (58), and then gently work the Chain Guard (14) over the Right Crank Arm (31) and away from the exercise bike.
