Note
Before setting the belt tension, the belt must not have been tensioned.
• Unscrew the 4 screws holding the protection cover and remove it. See figure
below.
• Check that the rollers are installed at exactly 90˚ in relation to the frame.
• Make sure that the belt has never been tensioned before and is now installed
without tension.
• Measure a distance of 1000mm in the middle of the belt and make a mark at
0 and 1000mm.
• Using both adjustment screws (see figure 15), tension the belt until the
distance between the marks is 1005mm.
• If a PVC belt is used the distance between the marks should be 1003mm
after tensioning the upper conveyor belt and 1004mm after tensioning the
lower conveyor belt.
• Clean off the marks.
• Mount the protection cover.
