8.1 - MANUAL LOWERING
In case of power failure the bollards go down automatically only if they are equipped with the automatic lowering
device. On the contrary, if bollards are not equipped with this device, in case of power failure they will remain in up
position and it will be necessary to perform a manual emergency lowering.
To perform the manual emergency lowering:
1.
Unfasten and remove the dowel placed on the frame of the bollard by means of the specific socket head screw
(provided).
2.
Insert the socket head screw down to the button for the manual lowering
.
3.
By pushing the socket head screw the bollard will go down; keep the socket head screw pressed until the
complete lowering of the bollard
4. F
asten the dowel.
