The pressure to be applied depends on the load-bearing capacity of the material. If
necessary, the pressure must be readjusted or changed as required during the first
stops until the lower edge of the screed no longer leaves any marks when the finisher
moves on again.
A pressure greater than 10-15 bar neutralises the screed weight, thus preventing the
screed from sinking into the material.

When combining the "paving stop" and "screed relieving" functions, make sure that
the pressure difference between the two functions does not exceed 10–15 bar.
m
Especially in those cases where the "screed relieving" function is only briefly used as
a start-up aid, there is a danger of uncontrolled floating when starting up again.
