N The adjustment procedure is finished if the running belt stays in the centre of the rear roller (tail shaft) after having
been operated at a speed of 12 km/h for at least 4 min.
N Uphill run and other running styles may lead to locomotion of the running belt. +/- 2 cm are to be considered as a
tolerance zone. As long as the running belt returns to the centre at a speed of
12 km/h, it must not be readjusted. The running belt will remain in the
adjusted position for a period of months if it has been adjusted correctly.
N During "reverse belt rotation" (downhill run), a re-adjustment of the belt
position (centring) is required.
N By evenly turning the left and right trimming screws to the right, the running
belt can be tightened if necessary. See chapter „running belt tension“.
Note: The running belt always has to be positioned within the marking for the correct lateral position.
Note: For running machines with a running surface of 200 x 75 cm and bigger, the trimming screw is located at the front
deviation shaft.
The oversize machine h/p/cosmos saturn 450/300rs has an automatic belt centring system with motors and sensors and
does not need to be centred manually; however, the user should observe the central belt position.
