5. DW 2944 Degree of Collapse Identification

Installation Steps:

1. Mount main mounting brackets
2. Inflate air bladder to 50 kpa ( 8 psi )
3. Measure distance L2 ( Drawing: DW 2922 and  DW 2923 )
4. Loosen bolts N
5. Adjust extension shafts to distance L1 ( L1 = L2 + 10 mm )
6. Equalize measurement L4 and L5
7. Tighten bolts N and locknuts
8. Remove bolts A and Clamp Block Cap M2 on the near side ( Drawing: DW 2921 )
9. Loosen bolts A on the far side by three full turns
10. Insert one round section of extension piece into Clamp Block M1/M2 on the far side
11. Place the remaining extension piece round section into Clamp Block M1 on the near side
12. Replace Clamp Block Cap M2 and bolts A on the near side
13. Ensure that bolts A on the near and far side are loosened by one full turn ( Drawing: DW 2921 )
14. Turn the unit on the horizontal axis till the blades are positioned 90 degrees to the belt
15. Tighten bolts A - both sides
16. Loosen bolts C - both sides one full turn
17. Move the unit up until the blades touch the belt on the near and far sides uniformly
18. Tighten bolts C - both sides
19. Ensure that the conveyor belt is running
20. Deflate the air bladder to 30 kpa
21. Loosen bolts B and move angle brackets E towards Clamp Blocks M1/M2 on both sides
22. Tighten bolts B - both sides
23. Loosen bolts C - both sides
24. By means of bolts G move clamping blocks M1/M2 towards the belt - both sides
25. As the parallelogram collapse, line the vertical center line of the blade with the vertical center line of the extension piece - both sides ( Drawing: DW 2943 )
26. Lock bolt G with locknut G1 - both sides
27. Tighten bolts C - both sides
28. Inflate air bladder 30 - 70 kpa to attain ideal cleaning
    a. Depending on belt speed
    b. Depending on belt condition
    c. Depending on stickiness of material
    d. Depending on moisture content of material
29. If any vibration occurs:
    a. Loosen bolts A half a turn - both sides
    b. Rotate unit 2 to 3 degrees towards the head pulley until vibration stops
    c. Tighten bolts A - both side
