Screed floating po-
sition
+ activation LED
/ screed stop
+ activation LED
Switches between floating screed functions and screed stop.
Toggle switch function:
- Toggle the switch forward (away from the operator): Screed stop.
- "Screed stop" is used to lock the screed hydraulics to prevent
the screed from sinking into the paved material when the paver
is stationary (intermediate stop).
"Screed stop" is not sufficient as a safeguard during transport or
maintenance work! Insert the mechanical screed transport safe-
guard!
- Toggle the switch back (toward the operator): Lower the screed
and switch to "floating position".
- During paving, the screed must always be in its floating posi-
tion.
This also applies to intermediate stops and truck changes.
As soon as the floating position function has been activated and the
screed is lowered, the screed lifting cylinder pressure is reduced.
The raise / lower screed function can be carried out while the screed
is switched to the floating position. Following adjustment, the screed
is automatically switched back to the floating position.
The floating position function is only active when the drive lever is
moved from its central position!
If the drive lever is moved to the central position, the paver automat-
ically switches to screed stop (or locked position).
The activation LED for screed stop is then activated.
