blade alignmenT
Once the entire screen length (end handles, truss frame
sections and engine) has been assembled final alignment
of the blades can begin. Use the following procedure for
blade alignment.
1. Place screed ends on a flat wooden support. Reference
Figure 20.
2. At approximately 1-inch (2.54 cm.) out from the leading
edge from the screed blade, drive a nail into the
wooden support. Nail should be on outside of support.
3. Attach a piece of string to the nail by tying a knot
around the nail.
4. Strech the string line as tight as possible and connect
it to the nail at the other end of screed by tying a knot
around the nail.
5. Make sure that the nail is contacting each support at
the point of blade contact.
6. Use a short, flat piece of metal or wood as a gauge to
compare the string to the bottom surface of the screed
blade and bullfloat blades at the splice point.
The string should just make contact with the metal/
wood gauge if the blades have been aligned properly.
If the string does not make contact with the gauge,
realignment is required.
7. The blades should be of equal height at each splice
point. If the height of the blades are not even, turn the
turnbuckle in a direction that achieves equal height for
both blades at the splice point.
8. Once all the blades have been aligned correctly, tighten
jam nuts on top pipe to prevent turnbuckle from rotating
during operation.
9. The screed is now ready for operation. Lift screed
onto form.
