ADJUST MATERIAL THICKNESS USING FLIGHT SCREW
Figure 19. Flight Screw.
This procedure can be done starting with either the left or the right side of the screed.
It is recommended that only one-half turn of flight screw per 10 ft of paving is performed while
actively paving to allow screed to settle into adjustment.
The amount of flight screw adjustment needed to achieve a sufficient change in material
depth will vary with terrain, material temperature, material thickness, and speed of BMPM.
The screed angle gauge is used as a reference point only. This number does not directly
reflect a measurement of material depth.
1. Unlock (Figure 19, Item 5) flight screw locking tab (Figure 19, Item 1).
2. Turn flight screw using flight screw handle (Figure 19, Item 2) until desired material thickness is reached.
3. Lock (Figure 19, Item 4) flight screw locking tab (Figure 19, Item 1).
4. Note screed angle gauge (Figure 19, Item 3), and adjust opposite side of screed to the same angle by
repeating steps 1 3.
