CONSOLE
If the console does not function properly, the wire harness should be checked See assembly step 4 on page 5.
Make sure that the wire harness 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 9 on page 7). Remove
the four 3/4" Phillips Screws (4) 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 3/8" Range Nuts (18) clockwise
one fuil 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
Nylon Lock Nut (73) 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 biski'tum the Bolt counterclockwise. Reattach
the side shields, neck shields and pedals.
TIGHTENING THE CRANK ARMS
If the crank arms become loose, they should be tight-ened 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
property tightened, tighten the hex nut.
