TENSIONING THE RUNNING BELT (NOTE: Running belt should NOT be moving during adjustments) 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 adjustment. To eliminate this slipping, turn the treadmill off and tension both the rear roller bolts with the appropriate size allen wrench, turning it 1/4 TURN to the right as shown. Turn the treadmill on and check for slipping. Repeat if necessary, but NEVER TURN the roller bolts more than 1/4 turn at a time. Belt is properly tensioned when the slipping sensation is gone.
CENTERING THE RUNNING BELT (NOTE: Running belt should NOT be moving during adjustments)
If the running belt is too far to the right side: turn the right adjustment bolt clockwise 1/4 turn at a time. Turn the treadmill on and check the belt alignment. Repeat if necessary, until the belt remains centered during use (using the supplied Allen wrench).
If the running belt is too far to the left side: turn the right adjustment bolt
