6.3 HOW TO ADJUST AND TENSION THE STRIDING BELT ON THE
LIFE FITNESS TREADMILL
Do not move treadmill or place hands under treadmill while it is plugged into an electrical outlet!
Tool required: 5/16" hex key wrench
THE BELT TENSIONING BOLTS
The Life Fitness treadmill has access holes in the rear roller guar ds, which allow access to the tensioning bolts.
These tensioning bolts make it possible to adjust tracking and centering of the striding belt (A) without removing the
guards.
NOTE: It is extremely important that the treadmill be correctly leveled pr ior to any tracking adjustments. An
unstable unit may cause striding belt misalignment. See "How To Stabil ize the Life Fitness Treadmill" in the "Set
Up" section prior to attempting any rear roller adjustments.
Before proceeding, it is helpful to visualize the REAR ROLLER (B) pi vot point (C). Each adjustment made to one
side of the ROLLER must be met with an equal and opposite adjustment (D) to t he other side of the ROLLER to
maintain an ideal belt tension at the pivot point.
TRACKING (CENTERING) AN EXISTING OR NEW STRIDING BELT
1 Locate the two access holes to the belt tensioning bolts on each of the rear roller guards.
2 Stand on the sides of the treadmill and straddle the belt, not standi ng on it. Enter the Manual Workout and set
the belt speed to run at 4.0 mph (6,4 kph).
3 If the striding belt has moved to the right, turn the right tension bolt 1/4 t urn clockwise with provided ¼” Allen
wrench, and then turn the left tension bolt 1/4 turn counter-clockwise to s tart striding belt tracking back to center
of roller.
4 If the striding belt has moved to the left, turn the left tension bolt 1/4 t urn clockwise and then turn the right
tension bolt 1/4 turn counter-clockwise to start striding belt tracking bac k to center of roller. Repeat adjustments
until striding belt appears centered. Allow machine to continue run ning for several minutes to observe if tracking
remains stabilized.
NOTE: Do not exceed one full turn of the adjusting screws in either directio n. If after one full turn the belt does not
track properly, contact Customer Support Services. The phone number s are listed in "How to Obtain Product
Service."
