ADJUSTMENTS & USAGE GUIDE
HOW TO MOVE THE ELLIPTICAL
Hold the Left & Right Handlebars (No. 37L/R) and tilt
the elliptical bike until the transportation wheels on the
Front Stabilizer (No. 4) touch the ground. Now you can
move the elliptical bike to the desired location.

Tension levels are set at Level 1 being the lowest and
Level 8 being the highest.
ADJUSTING THE BALANCE
In order to achieve a smooth and comfortable ride, you
must ensure that the elliptical is stable. If you notice that
the elliptical is unbalanced during use, you should adjust
the Rear End Caps (No. 2) located beneath the Rear

ADJUSTING THE SEAT
Loosen and pull out the Pin Knob (No. 61) to adjust the
height of the seat. You may also slide the seat forward or
backwards by loosening the Adjustment Knob (No. 16)
