5. There will normally be a drop in belt tension during the
first 24 to 48 hours of operation due to stretch and the
belts seating themselves in the sheave grooves.
6. After this initial “RUN IN” period, the machine should
be stopped and the belts should be re-checked for
tension. The motor position should be adjusted until
the deflection matches the force required.
7. In no case should the belts be over-tensioned as this can
significantly reduce belt and/or bearing life.
