Screed charging/relieving
This function charges or relieves the
screed regardless of its own dead
weight.
Switch (1) has the following positions:
A: Relieving (screed ‘lighter’)
B: Function Off
C: Charging (screed ‘heavier’)
Switch positions „Screed charging/relieving” are only effective when the paver finish-
er moves. When the paver finisher stops, „screed stop” is automatically selected.
Screed control with the paver finisher standing still
(Floating position with and without prestressing)
When „stopping the screed“ the relieving pressure and the counterpressure of the
material will provide retention so that the sinking of the screed is avoided when a tem-
porary stop occurs.
Using the switch (2) the following posi-
tions can be selected:
A: automatic floating position with pre-
stressing, if the drive lever is in cen-
tral position
C: only floating position, if the drive le-
ver is in central position.
A
Position (C) is to be used for adjusting the paver finisher and for lifting/lowering of the
screed, and position (A) needs to be used for laying.
m
In case of transportation or maintenance operations always insert the mechanical
transportation safeguard of the screed.
