These instructions are to be followed when centering an existing or new striding belt or
tensioning an existing striding belt.
Tracking (Centering) an Existing or New Striding Belt
Step 1
Locate the two belt tensioning bolts on each side of the rear frame cap.
Step 2
Enter the Manual program and set the belt speed to run at 4.0 mph (6.4 kph).
Step 3
Before proceeding, it is helpful to visualize the REAR ROLLER pivot point as shown in the
illustration below. Each adjustment made to one side of the ROLLER must be met with an
equal and opposite adjustment to the other side of the ROLLER to maintain an ideal belt
tension at the pivot point.
