TROUBLE-SHOOTING AND MAINTENANCE

Inspect and tighten all parts regularly. Outer surfaces of the exercise bike can be cleaned with a damp cloth and
mild, non-abrasive detergent. Keep liquids away from the console.
CONSOLE
If the console does not function properly, the batteries should be replaced. See assembly step 4 on page 6. Make
sure that the sensor wire is plugged fully into the wire extending from the console.
ADJUSTING THE TENSION BELT
If the tension belt slips as you pedal, the tension belt should
be tightened. First, disconnect the Link Arms (37) from the
Pedals (10) (see STATIONARY MODE on page 8). Next,
remove the Pedals (see assembly step 8 on page 7). Remove
the four #8 x 1" Screws (15) from the Left and Right Neck
Shields (67, 68). Remove the #8 x 1" Screws (15) and the 3/4"
Tec Screws (69) from the Left and Right Side Shields (16, 34).
Slide the Side Shields off the exercise bike. To tighten the
tension belt, turn both of the 1/4" Nylon Locknuts (18)
clockwise one full turn. Repeat until the tension belt no longer
slips. Reattach the Side Shields, Neck Shields and Pedals.
CENTERING THE TENSION BRACKET
If a grinding noise is heard as you pedal, the Tension Bracket
(35) should be adjusted. Disconnect the link arms from the
pedals, remove the pedals, and remove the side shields (see
ADJUSTING THE TENSION BELT above). Hold the 3/8" x 16
Locknut (31) with a wrench. If the Tension Bracket is touching
the right side of the Resistance Disk (22), turn the Tension
Bracket Bolt (60) clockwise until the Tension Bracket is
centered. If the Tension Bracket is touching the left side of the
Resistance Disk, turn the Bolt counterclockwise. Reattach the
side shields, neck shields and pedals.
TIGHTENING THE CRANK ARMS
If the crank arms become loose, they should be tightened in
order to prevent excessive wear. Loosen the hex nut on the
left arm of the Crank (27). Place the end of a standard
screwdriver in one of the grooves in the crank nut. Lightly tap
the screwdriver with a hammer to turn the crank nut
counterclockwise, until the crank arms are no longer loose.
Do not overtighten the crank nut. When the crank nut is
properly tightened, tighten the hex nut.
