OPERATING MANUAL
2.6.2 Screed lock
The screed is locked to prevent a spontaneous fall of the screed
due to possible leaks in the hydraulic system.
Lock the screed with the machine parked and started, the travel
controller (8) must be set in the neutral position (N).
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.
Procedure for locking the screed:
• Set the travel controller (8) to the neutral position (N).
• Check that both screed lock pins (2) are inserted.
• Set the engine speed adjusting controller (10) to the maxi-
mum speed.
• Switch over the transport/operating mode switch (15) to the
upper position.
• Press the foot switch (48).
• To lift the screed, switch over the switch lift/lower switch
(19) up, and after reaching the maximum screed position
release the switch.
• Release the foot switch (48).
• Extend both the screed lock pins (2).
• Press the foot switch (48).
• Lower the screed until the screed tow arms (3) lie on the lock
pins (2).
• After the contact of the screed tow arms (3) with the lock
pins (2), switch over the screed lift/lower switch (19) to the
central position.
Procedure for unlocking the screed:
• 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
upper position.
• Press the foot switch (48).
• To lift the screed, switch over the switch lift/lower switch
(19) up, and after reaching the maximum screed position
release the switch.
• Release the foot switch (48).
• Retract both the screed lock pins (2).
• Set the screed to the required position.
Due to leaks in the hydraulic system, the screed may
gradually lower if the screed tow arms are not locked.
In case of failure of the hydraulic system, the screed may
fall spontaneously if the screed tow arms are not locked.
In the event of failure of the hydraulic system, there is
a risk of injury from the falling screed.
If the screed of the machine is not in use, during move-
ment or transport of the machine on another vehicle, the
screed tow arms must always be locked using lock pins.
