2) Replace the belt with the one shown in Table 5-1-1.
3) To provide appropriate belt tension, measure the length of the belt with no tension exerted,
and adjust the position of the transport pulley along the slot so that the belt length increases
by 0.5%.
<Adjustment procedure>
Use a pencil or similar tool to put two marks, which are 200mm apart from each other, on the belt.
Move the transport pulley to exert tension so that the distance increases to 201 mm.
At this time, regarding the front and rear buffers, be careful not to lift by applying belt tension.
