Aura Series
The Aura Series was originally designed with a reinforced 15/16” flat Kevlar/urethane belt. Later, a line
extension was designed using cables. Belts and cables are NOT interchangeable.
Cables
Important: A minimum of ½” (13mm) of the cable bolt must be engaged into the head plate adapter
Cable Tensioning Procedure:
1. Unpin the weight stack pin from the stack
2. Remove the cable bolt from the head plate adapter
3. Turn down the cable bolt so ½” (13mm) of the bolt is engaged into the head plate adapter (see
image below)
4. Check cable tension. If you have no more than ½” (13mm) deflection the cable is tensioning
properly (see checking for proper tension procedure above)
• If you have too much deflection, turn the cable bolt down a few turns and check tension
again. Do this until proper deflection is achieved
5. Tighten jam nut down the cable bolt so it is tight to the head plate adapter. You must secure it
with a wrench. Finger tight is not good enough.
6. Use the weight stack pin and pin 50-60 lbs. then perform 5-7 reps to set/stretch the cable
7. Check for proper tension (see above)
8. Check to make sure the weight stack pin goes into each weight plate. If the pin touches the
bayonet, that is fine as long as the pin can be inserted completely.
• If not, loosen the jam nut on the cable bolt and turn out 1 thread then recheck.
Note: On some machines, such as the cable Leg Press, there will be additional adjustment at the opposite
side of the cable. Only adjust there if you run out of bolt threads above the weight stack.
