A 5/16-inch Allen 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
How To Position and Stabilize the Life Fitness Treadmill
at the beginning of
this section 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.

After installing and levelling the treadmill, check the belt to ensure that it is tracking properly. First, plug the power cord
into an appropriate outlet. See
Electrical Power Requirements
at the beginning of this section for details. Then turn the
treadmill ON. Two people are needed to perform this procedure.
1.
Locate the access hole in the rear roller guards to access the belt tensioning bolts.
2.
One person stands on the side rails of the treadmill and straddles the belt. This person presses the MANUAL workout
and sets the belt speed to 7.0 mph (11.0 kph).
3.
If the striding belt has moved to the right, the second person turns the right tension bolt (E), using a 5/16-inch Allen
wrench, 1/8-turn clockwise and then turns the left tension bolt (F) 1/8-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 1/8-turn clockwise and then turn the right tension bolt
1/8-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 unit to continue running for several minutes
at 7.0 mph (11 kph) to observe if tracking remains stabilized.
Note:
Normal belt operating position is for the belt to be located within the
belt travel indicators (triangles) (G) on the rear roller guards.
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. Do not overtighten the tensioning bolts while making belt
adjustments. overtightening of bolts may overstretch and damage the striding
belt or roller.
