WARRANTY
This jack is covered by a 12-month warranty starting from the date the warranty comes into effect or from the date the
jack leaves our factory if it has not already been rendered effective on-line; it covers all manufacturing defects but not
transport expenses, defects caused by improper use or damages suffered during transport. For more details please see
the card attached to this manual.
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: this must be done with the pistons completely
lowered. The oil level must be up to the small bolt that is on the side of the cylinder/tank, you can check by loosening it.
If you have to top up the oil in the tank make certain the oil you are using is compatible with what is already inside the
tank so as not to compromise machine integrity. DWG. 15
- If the oil level is higher than it should be, even by only a little, or if the jack has been turned up- side down (as can easily
happen during transport), the oil is expelled through the suction pump as mist. This phenomenon disappears on Its own
when the oil level hase been restored. If the oil inside the tank exceeds the level by a lot, it is advisable to remove some
until it is back in the norm.
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 pistons must be moved out completely.
2. Remove the casing and close the cock no. 0843.
3. Turn the jack over on to one side, leaving free access to the dowel no. 0541 on the side of the base. DWG. 16
4. Loosen (NEVER unscrew the dowel completely!) the dowel no. 0541 and move the pistons back in by hand.
5. Let all the air out from the dowel and continue until oil starts coming through and then close the dowel.
6. Put the jack back into the working position.
7. Open the cock no. 0843.
8. Move the pistons back in completely and check oil level.
9. Try to operate the jack without any load and if the piston lowers in jerks repeat the procedure at least 2 or 3 times.
