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
AIR BLEEDING
Each time the jack is serviced, with parts connected to the tank or motor pump removed and refitted, it is advisable to
bleed off all air.
Bleeding phases:
1. Position the jack on the workbench
2. Operate the raising control to allow the pistons to come to a fully extended position
3. Operate the raising control again for 2 seconds until the pistons lock in place
4. Make sure the pistons are now locked in place and cannot be rotated
5. Operate the lowering control until the pistons begin to come down
6. Ensure that the pistons can be rotated now. Remove the cover and close the cock
7. Turn the jack over on its handle, as illustrated in the drawing DWG. 16
8. Loosen (NEVER unscrew it completely!)
Loosen (NEVER unscrew it completely!) the grub screw
all the air out, until hydraulic fluid starts flowing out. When finished, tighten the grub screw
9. Position the jack back on the base and open the cock
10. Operate the lowering control to get the pistons to fully retract.
11. Check the hydraulic fluid level
12. Try to operate the jack without any load. If the pistons do not lower smoothly, repeat the bleeding procedure at
least 2 or 3 times
