1. 
   E51238-19-20FEB02

   Unroll 1 m (3 ft) of material from the roll of net being used. Locate a starting point in the net and, with net wrap pulled snug, measure between 10 weaves as shown in the illustration. Divide the measurement by 10 to obtain the initial net measurement.

---




2. Thread net properly and make, wrap, and unload a bale

3. Examine the bale for inconsistencies in diameter and take the stretch measurement at an average diameter. Do not use areas where there are excessive bunches of crop or voids in the bale as measuring points.

   Locate the end cut-off on the bale. Use the net directly under the cut-off as a starting point for measurement.

4. Take the measurement between 10 weaves as shown in illustration. Divide the measurement by 10 to obtain the net stretch value.

5. The net stretch value must be 3—4 mm (0.118—0.157 in) greater than the value measured in Step 1. If measurement is not within this range, proceed to Step 6.

   A - Cap Screw

   B - Sheave

   C - Cap Screw (3 used)

   D - Shims (stored)

   E - Shims (in use)

   Put pressure on sheave (B) using the brake lever while loosening the three cap screws (C), shims (D) and cap screw (A).

7. Release the brake lever.

8. Remove the cap screw (A) and washer.

9. Remove the three cap screws (C), shims (D), and outer sheave (B).

10. Transfer shims (E) to and from stored location (D) to meet the net stretch value of 3—4 mm (0.118—0.157 in) more than the value measured in Step 1.

    • Decreasing the number of shims (E) between sheave halves increases the distance.
    • Increasing the number of shims (E) decreases the distance.
    
    

11. Install the belt and assemble sheave (B) in reverse order using the following special instructions:

    • Install cap screw (A) and tighten to specification.
