Step 5
Now repeat Step 4 (Page 24) on the inlet end of the feeder. Again, be careful not to cut or
scrape the belt on any components.
Step 6
When both ends have been pulled to the outside of the side rail, you may grab the belt in the
middle and slowly remove it. As you are removing the belt, mark the direction the belt was
rotating, as this will allow you to re-install it in the same direction. Take care when storing the
belt to prevent kinks or other damage
Step 7
With the belt removed, inspect the feeder for material buildup, lodged particles, and signs of
wear, paying close attention to the weighing section. Take care when cleaning the weighing
section, as 6 kg (15 lbs) (or less) pressure placed on the weighbridge could cause load cell
damage.
Step 8
Reverse Step 7 (Page 25) to Step 1 (Page 24) to re-install the same belt.
Note
• On a new replacement belt, there may be an arrow printed on the underside of the belt.
This arrow indicates what direction the belt should rotate when it is installed. If there is no
arrow, rotation of the belt may be in either direction. Whenever a new belt is installed,
perform the belt tracking procedure (see Belt tracking (Page 26)).
• New belts should be un-rolled and allowed to relieve any kinks or bends: this will help
tracking and weighing accuracy.

Belt tension
The ideal belt tension for any weighfeeder is just enough tension to prevent the belt from slipping
on the drive pulley. The tension minimizes the effect of the belt on weighing accuracy. Often, the
sole cause of an inaccurate weighfeeder is excessive belt tension.
Specific belt tension cannot be given because the weighfeeder could be mounted in various
applications. As a general guideline, the bottom of the belt should droop 1-2 inches over the
