Tensioning Matrix Treadmill Belts

Tensioning the Running Belt
If you feel a slipping sensation when using your treadmill, the running belt may need to be tightened. In most cases, the belt has stretched from use, causing it to slip. This is a normal and common adjustment.
1) Make sure that the unit is turned off and that the belt has come to a complete stop.
2) To eliminate slip, adjust rear roller bolts with the appropriately-sized Allen wrench, tightening both the left and right bolts 1/4 turns as shown below.
3) Try the treadmill again to check for slipping.
4) Repeat if necessary, but never tighten roller bolts more than 1/4 of a turn at a time.
WARNING - Over-tightening the running belt may cause damage to the roller bearings and/or to the belt itself.
