MAINTENANCE
When performing maintenance always check that the by-
pass screws are set correctly, that the system is balanced
and that the safety devices operate correctly.
10.1.
TOPPING UP WITH OIL
Check periodically the quantity of oil inside the tank.
For medium/low duty cycles a yearly check is sufficient; for
more severe operation it is advisable to check every 6
months.
The oil level must not be lower than the index line.
To top up, unscrew the filler cap (fig. 16) and pour in oil up
to the correct level.
Use exclusively FAAC XD 220 oil.
10.2.
BLEEDING AIR FROM HYDRAULIC CIRCUIT
If the beam moves in an irregular manner, this may be due
to the presence of air in the hydraulic circuit.
If it is necessary to bleed the air, proceed as follows:
1)
Check that the breather screws have been removed
(fig. 16).
2)
Disassemble the lateral drive shafts from the operator.
3)
Set an operating time of about 1 minute on the
electronic control unit.
4)
Activate the operator electrically so that it turns to the
end of its travel in both directions of rotation.
5)
Repeat this operation several times if necessary.
6)
Follow the installation instructions to reassemble.
