Adjustments to the Running Surface |
8. Adjustments to the Running Surface
Important!
When using the treadmill, make sure that the running belt is between the markings. If this is not the
case, please stop the treadmill training and adjust the running belt accordingly.
8.1 Belt Adjustment
The belt adjustment takes place during the belt run at a speed of approx. 6 km/h (possibly less). No one
may run on the belt during adjustment! If the strap moves to the right, turn the right adjusting screw
(top picture) clockwise with the enclosed socket wrench by a maximum of a quarter of a turn. Run the
belt and check whether it runs properly. Repeat the process until the belt is running straight again. If the
belt deviates to the left, turn the right adjusting screw (top picture) counterclockwise with the enclosed
socket wrench by a maximum of a quarter of a turn. Run the belt and check the operation. Repeat this
procedure until the belt is running straight again.
8.2 Belt Tightening
EN
Turn the adjusting screw (top picture) clockwise for max. one turn. Repeat the process on the other side.
Check whether the endless belt slips. If this is the case, you must perform the described procedure
again.
Be very careful when adjusting and tightening the belt; extreme over- or undertensioning can damage
the treadmill!
