   B - Jam Nut

   C - Locking Nut

   D - Adjusting Nut

   E - Distance

   F - Lock Nut (4 used)

   Adjust belt tension as follows:

   1. Remove slack from belt by pulling both slide plates by hand.

   2. Tighten adjusting bolts (A) until they touch the slide plates.

   3. Tension belt forward an additional 75 mm. This will make distance (E) approximately 110 mm with most belts.

   4. Tighten locking nut (C) and jam nut (B).

2. NOTE: It is normal for belt to track side-to-side approximately 2 mm in either direction.

   Check belt for proper tracking as follows:

   1. Rotate belt by hand approximately 3 m (10 ft). If belt tracks towards one side and will not return to center, adjustment is necessary.

   2. If adjustment is required, tighten adjusting bolt (A) one flat (1/6th turn) at a time, on the side where belt is rubbing; then rotate by hand again to see if tracking returns to center.

   3. Run conveyor at slowest speed and observe tracking. If additional adjustment is necessary, continue to tighten adjusting bolt in small increments until belt tracks side-to-side approximately 2 mm in either direction without contact to housing.

   4. Repeat as necessary until belt is centered.

   5. Tighten lock nuts (F).
