1.4 Starting for paving
Set the switches, levers and controls listed below to the specified positions when the
screed has reached its operating temperature and a sufficient amount of material lies
in front of the screed
- Push the drive lever (1) all the way to the front and start driving.
- Observe the distribution of the material and adjust the limit switches if necessary.
- Set the compacting elements (tamper and/or vibration) according to the required
compaction ratio.
- Let the paving master check the paving thickness after 5–6 meters and correct
if necessary.
Carry out the check in the area of the caterpillar chains or drive wheels as the screed
tends to level an uneven ground. The reference points for the layer thickness are the
caterpillar chains or drive wheels.
The basic setting of the screed must be corrected when the actual layer thickness de-
viates significantly from the values indicated by the scales (see the operating instruc-
tions for the screed).

The basic setting is for asphalt material.
