A 5/16-inch hex key wrench is required for this task. The Life Fitness Treadmill has access holes in the rear roller guards
which allow access to the tensioning bolts. These tensioning bolts make it possible to adjust the tracking and centering
of the striding belt (A) without removing the guards.
NOTE: It is extremely important that the treadmill be correctly leveled prior to any tracking adjustments. An unstable unit
may cause striding belt misalignment. See the topic titled "How To Stabilize the Life Fitness Treadmill" in the Section 1.2,
titled Set Up, prior to attempting any rear roller adjustments.
Before proceeding, it is helpful to visualize the REAR ROLLER (B) pivot point (C). Each adjustment made to one side of
the ROLLER must be met with an equal and opposite adjustment (D) to the other side of the ROLLER to maintain an
ideal belt tension at the pivot point.

RACKING ENTERING
Two people are needed to perform this procedure.
1 Locate the two access holes to the belt tensioning bolts on each of the rear roller guards.
2 One person stands on the side rails of the treadmill and straddles the belt. This person presses the MANUAL work-
out and sets the belt speed to 2.5 MPH (4.0 KPH).
3 If the striding belt has moved to the right, the second person turns the right tension bolt a quarter-turn clockwise and
then turns the left tension bolt a quarter-turn counter-clockwise to make the striding belt track back to the center of
the roller.
If the striding belt has moved to the left, turn the left tension bolt a quarter-turn clockwise and then turn the right ten-
sion bolt a quarter-turn counter-clockwise to make the striding belt track back to the center of the roller.
4 Repeat the adjustments until the striding belt appears centered. Allow the machine to continue running for several
minutes at 4.0 MPH. (6.4 KPH) to observe if tracking remains stabilized.
NOTE: Do not exceed one full turn of the adjusting screws in either direction. If after one full turn the belt does not track
properly, contact Customer Support Services. The phone numbers are listed on page one.
