MAINTENANCE JOBS FOR THE END USER

- 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 7.7 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, POS. 9 GRP1GRS POS. 9 GRP1GRS
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 screw
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 refitting parts connected to the tank and motorpump, it is advisable to bleed
off all air.
Bleeding phases:
1. The piston must be moved out completely.
2. Loosen (NEVER unscrew the dowel completely!) dowel
extension on the plate, and let all the air out from the dowel, continuing until oil starts coming out and then close
the dowel. (DWG. 16)
3. Move the piston back in completely and check the oil level.
4. Try to operate the jack without any load and if the piston lowers in jerks repeat the procedure at least 2 or 3 times.
