3-12 l Installation
Adjusting Belt Tension
For Puller Model CPC 3-20 (continued)
4 Adjust belt tension, if necessary. Adjust tension by turning the threaded ten-
sion rods. Keep tension on front and back edges, top and bottom belts as even
as possible.
5 Fine-tune the tension:
• Lower the belts to a gap of about 1/8 in. (3 mm).
See Installation Section entitled, Setting the Belt Gap.
• Check the appearance of the belt gap. From the upstream end, look
down the length of the belts. The shape of the gap should not be
concave (over-tightened) or convex (too loose). Adjust the tension until
the gap is even.
• Check the tension and readjust as necessary.
