If the surface is slick when touched, then no further lubrication is needed.
If the surface is dry to the touch, apply a suitable silicone lubricant.
We recommend you use a silicone based spray to lubricate your Lifespan Treadmill. This Can be
purchased from your local sports Retailer or a local hardware store.
6.5 Belt Adjustment
Belt Tension Adjustment-It is very important for joggers and runners in order to provide a smooth, steady
running surface. Adjustment must be made from the right and left rear roller in order to adjust tension with the

in diagram below:

Note: Adjustment is thru the small hold on the end caps.
Tighten the rear roller only enough to prevent slippage at the front roller. Turn both the right and left bolt
clockwise reasonably and inspect for proper tension. When an adjustment is made to the belt tension, you must
also make a tracking adjustment to compensate for the change in belt tension.
DO NOT OVERTIGHTEN - Over tightening will cause belt damage and premature bearing failure.

near one side while the belt is running with no one on it. After a few minutes of use, the belt should have a

The procedures are as below:
▲ First set speed at lowest position.
▲ Second check the belt shifts to which side.
If the belt shifts to right, tighten the right bolt and loosen the left bolt by using 6mm Hexagonal
Wrench, until the belt is centered itself; If belt shifts to left, tighten the left bolt and loosen the right bolt by
using 6mm Hexagonal Wrench, until the belt is centered. When adjusting the belt using the 6 mm Hexagonal
