RAISING AND LOWERING SCREED -- CONTINUED.
Raising screed using screed raise key will raise the screed and lock screed into position. This is
useful for performing maintenance, transporting BMPM while not paving, and loading and
unloading from trailer. This is not used to adjust material height while paving, as this does not
allow screed to float. Raising screed using screed raise key should not be done to adjust material
height. Use the flight screw and/or tow hydraulic cylinder raise and lower keys.
1. Press and hold screed raise key (Figure 4, Item 1) until desired screed height is reached (Figure 3, Item 2),
and then release key.
When screed lower/float key is pressed, the screed is placed in a float setting. The screed will
lower to the ground unless the screed raise key is pressed. The screed should normally be
placed in a float setting whenever paving is performed. The screed lower/float key is not used
to adjust material height while paving.
After moving forward while screed is in the float setting, the BMPM will initiate a hold screed
setting whenever the BMPM is not moving forward. This is to ensure the screed does not
settle further into material when BMPM is stopped. The screed will resume float when forward
motion is resumed.
2. Press screed lower/float key (Figure 4, Item 2) to lower screed to the ground and place screed into float
setting (Figure 3, Item 1).
