2.6.1 Lifting and lowering the screed
The machine is equipped with a screed linear hydraulic motor

The screed linear hydraulic motor (3) is controlled by means of the
screed lift/lower switch (19) on the main dashboard of the ma-
chine, or by means of the foot switch (49) on the footboard of the

The screed can be set to the upper, locked or floating position.
Lifting and lowering of the screed can be performed in the
transport or operating mode.
Procedure for lifting/lowering of the screed in the transport
mode:

lift/lower switch (19) to the central position.
• To lift the screed, switch over the switch lift/lower switch
(19) up.

• Release the foot switch (48).
Procedure for lifting of the screed in the operating mode:
• The setting of the lifting and lowering of the screed in the
operating mode is used during material paving.
• Set the travel controller (8) to the neutral position (N).
• Set the engine speed adjusting controller (10) to the maxi-
mum speed.
• Switch over the transport/operating mode switch (15) to the

There is a risk of injury from the moving screed tow arms
or the moving screed.
If the screed of the machine is not in use, during movement
or transport of the machine on another vehicle, the screed
tow arms must always be locked using lock pins according
to Chapter 2.6.2.
