6.2 TOPPING UP THE OIL LEVEL
1. Release and lower the bollard following points 1 to 5 in the §
"Release procedure" section.
2. Unscrew the plug of the hydraulic unit 26.
The oil level should be checked when the bollard is in the lowered
position.
An overflow pipe below the plug prevents the control unit from be-
coming too full. There should be oil in the pipe when the cylinder is in
the down position. If necessary, top up the oil to the rim of the pipe.
3. Close the automation.
4. Replace the plug of the hydraulic unit when the bollard is in the
raised position.
5. Install the head following points 2 to 6 in the § "Restoring auto-
matic operation" section.
6.3 BLEEDING THE SYSTEM
1. Remove the head of the bollard following points 1 to 4 in the §
"Release procedure" section.
2. Unscrew the plug of the hydraulic unit.
3. Open and close the automation several times with the plug
removed.
4. Replace the plug of the hydraulic unit when the bollard is in the
raised position.
5. Install the head following points 2 to 6 in the § "Restoring auto-
matic operation" section.

6.4 ROUTINE MAINTENANCE
The Scheduled Maintenance table lists the operations that must
be performed on a regular basis in order to keep the automation sys-
tem working reliably and safely; these are given purely as a guideline
and should not be considered exhaustive. The installer/machine
manufacturer is responsible for drawing up the maintenance plan
for the automation system, supplementing this list or modifying
the maintenance intervals according to the machine characteristics.
