4.8 TENSIONING THE RUNNING BELT
Running belt should NOT be moving during tensioning. Over tightening the running belt can cause ex-
cessive wear on the treadmill as well as its components. Never over-tighten the belt.
If you can feel a slipping sensation when running on the treadmill, the running belt must be tightened. In
most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common ad-
justment. To eliminate this slipping, turn the treadmill off and tension both the rear roller bolts using the
supplied Allen wrench, turning them . turn to the right (clockwise) as shown. Turn the treadmill on and
check for slipping. Repeat if necessary, but never turn the roller bolts more than . turn at a time. Belt is
properly tensioned when the slipping sensation is gone.
4.9 .CENTERING THE RUNNING BELT

ning at 1 mph turn the LEFT adjustment bolt counter-clockwise a . turn and wait for the belt to adjust it-
self.
Use the motor cover marking or part line as a reference for alignment.
Repeat if necessary, until the belt remains centered during use.
If the running belt is too far to the left side: Using the supplied Allen wrench and with the treadmill running
at 1 mph turn the LEFT adjustment bolt clockwise a . turn and wait for the belt to adjust itself.
Use the motor cover marking or part line as a reference for alignment.
