closing the safety cock, between the quick coupling of the air inlet and
the distributor itself. DWG. 14

IMPROPER USE
The air-hydraulic jack has been designed and made to lift transport
vehicles. Any other use of the jack, such as for instance lifting and/or
moving persons, is considered to be de nitely improper.
Any use of the jack not in conformity with the safety rules listed in this manual is considered to be improper use.
MAINTENANCE
To ensure your jack a long life it is advisable to clean the pistons externally once a fortnight.
Check the level of oil in the tank at least twice a year.
CHECK THE OIL LEVEL
IMPORTANT: the maximum quantity of oil in this jack is 1.2 L.
Compatible oil: ATF DEXRON IID. Please follow the steps listed here to check
the oil level:
1. Bleed off the air (see procedure in the next section)
2. Position the jack horizontally with the pistons down
3. Undo the screw (see DWG 15)
4. If, once this screw has been undone, no oil comes out it means the level
is too low. Add oil in this case. The level must be at the height of the small
bolt on the side of the tank, under the casing.
5. If oil does come out, let the excess quantity drain off until the right level is reached (see point 4).
AIR BLEEDING
Each time the jack is serviced, removing and re tting parts connected to the tank and motorpump, it is advisable
to bleed off all air.
Bleeding phases:
1. The pistons must be moved out completely.
2. Remove the casing and close the cock.
3. Turn the jack over on to one side, leaving free access to the dowel no. on
the side of the base. DWG. 16
4. Loosen (NEVER unscrew the dowel completely!) the dowel and move the
pistons back in by hand.
