Removal
► Use the software to move the conveyor sides into a position which allows you best access. As
an alternative, you can loosen the clamps for the relevant sides in dual conveyors.
7.2 "Loosening the Conveyor Side Clamps" [}207]
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Loosen the hexagonal shaft on the belt drive or conveyor drive (motor), so that you can move
the shaft freely. To do this, dismantle the hexagonal shaft fixture on one side and the corres-
ponding plastic bearing on both sides.

► Loosen the movable idler pulley (2).
► Loosen the top two idler pulleys(1).
► Remove the screws fastening the belt
drive(4) (or conveyor drive).
► If you replace a conveyor belt in the
placement area, you will also need to
loosen the top retaining screw (3) on
the spring. Make sure that you do not
lose the spring and the bushing on the
screw. When you refit them, check the
bushing for correct orientation.
► Carefully unthread the conveyor belt.

Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
●
Check the new toothed belt before fitting it. Hold it up high. It should hang loose and should
not twist.
●
Make sure that you do not fold or otherwise damage the toothed belt.
●
Make sure that the toothed belt is positioned accurately in the guidance on the motor shaft or
in the belt drive.
●
If you have loosened the spring, check the bushing for correct orientation when you fit it back
again.
7.7.1 "Replacing the Clamping Plate, Spacer Disks and Tension Spring" [}255]
●
When you tighten the movable roller, set the tension of the toothed belt correctly.

7.6.2 Setting the belt tension (conveyor belt)
The precalculated values for setting the belt tension can be found in the following chapters.
In addition, the value for any section of the conveyor belt can be calculated using a formula (see
7.6.2.2 "Calculating the belt tension" [}249]).
