Tensioning The Running Belt - Horizon Fitness T61 Service Manual

Te ns i oni ng the Ru nnin g Be l t
If you can feel a slipping sensation when running on the treadmill, the running belt must be tight-
ened. In most cases, the belt has stretched from use, causing the belt to slip. This is a normal and common
adjustment. Make sure that the unit is turned off and not running. To eliminate this slipping, tension both
the rear roller bolts with the appropriate sized Allen wrench, turning both the left and right bolt 1/4 TURN as
shown below. Try the treadmill again to check for slipping. Repeat if necessary, but NEVER TURN the roller
bolts more than 1/4 turn at a time.
