8. MAINTENANCE
When performing maintenance always check that the by-pass
screws are set correctly, that the up-and-over door is balanced
and that the safety devices operate correctly.
8.. TOPPING UP WITH OIL
Check periodically the quantity of oil inside the tank.
For medium/low use frequencies 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. 1 ref. 4) and pour in oil up
to the correct level.
Use exclusively FAAC HP OIL.
8.2. BLEEDING AIR FROM HYDRAULIC CIRCUIT
If the door 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. 1 ref. 15).
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.
