Adjusting Anti-Gravity Treadmill Speed and Direction
Treadmill speed is expressed as a numerical value in miles per hour (mph) or kilometers per hour (km/h).
Speed is adjusted in 0.1 mph (or 0.1 km/h) increments. Increase or decrease the speed using the up and
down arrow speed controls. If you decrease speed all the way to 0, the treadmill surface stops.
Adjust treadmill speed using the up arrow and down arrow button controls. In the forward direction, speed
will start at 0.1mph (0.16km/hr) and will increase in 0.1mph (0.16km/hr) increments for each button tap up
to a maximum of 12mph (19.3km/hr). Holding either button down for more than 2 seconds causes the speed
to increment or decrement at a faster rate.

To determine the maximum speed for your particular treadmill model, see “Appendix A: Anti-Gravity
Treadmill Specifications”.
Adjusting Body Weight
To minimize any discomfort while exercising, adjust the user’s body weight. It may not be necessary to
reduce weight by a large percentage to feel a considerable change. Start with a small percentage; a
reduction of only a few percentage points can significantly change your perceived exertion.
As the user’s conditioning gets better and they become accustomed to running, they will find that you can
incrementally increase their body weight and still remain comfortable.
CAUTION
: Change body weight percentage slowly at lower values (<50%). When operating
at low percentage body weights, do not allow the user to jump or perform other unusual
maneuvers. At such light weights, the user can become elevated off the treadmill surface to
the point of becoming unstable.
