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 which is at the back of the jack DWG. 14, 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.
- If the oil level is higher than it should be, even by only a little, or if the jack has been turned upside 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.
MAINTENANCE RESERVED TO A PROFESSIONALLY QUALIFIED
ENGINEER
Having to carry out maintenance or overhauling, use exclusively genuine spare parts to ensure the utmost reliability for
the jack.
PROBLEMS
Solutions
THE MOTOR WILL NOT START, OR IT RUNS BADLY
- Check that the air supply line is not choked. - The seals (760) are worn, replace them! - The seals (760) fitted on
the piston (755) have difficulty in sliding: both the cylinder and the ram have to be dismantled and lubricated.
THE JACK DOES NOT LIFT THE LOAD
- Check the oil level by means of the screw (1401). - There is dirt underneath the valves : remove the casing,
loosen the cap (518), remove the bearings and springs and blow inside to thoroughly clean it. Next, reassemble and
if necessary knock the bearings again (40) and (521), repeat the bleeding operation illustrated on the previous page
and put the jack back into its normal position and reopen the tap. - Check the hydraulic block (2082), paying special
attention that the pistons (89) and (264), which control opening and closing of the descent valves, have not become
rigid, in which case dismantle them and grease them.
