jerking movements. If the lowering action is unsteady, repeat the cycle until the lowering of the pistons is completed in a
steady and uniform way. This will show that the draining operation has been successfully completed.
3.9. Now the jack is ready for operation.
3.10.
Lifting
Positioning the jack under the lifting point of the vehicle, and following all of the safety instructions described, the
lifting operation is performed by moving the to lever control (2, Fig.3) to the UP position and holding it there until the
vehicle has been lifted to the desired height. Immediately place metal stands or another appropriate method to support
the elevated vehicle.
3.11.
Lowering
Check that there are no obstacles or people underneath the vehicle. Once the operation is completed, remove
the mechanical support stands by lifting the vehicle slightly in order to simplify their removal. Lowering is performed by
moving the handle (2, Fig.3) to the DOWN position and maintaining it until the operation is completed. To avoid brusque
lowering operations, the jack is fitted with a system which automatically regulates and controls the lowering operation
(L.C.S.).
3.12. Proceed to retract the pistons by pushing and holding the handle (2, fig.3) in the DOWN position until they are fully
introduced.
3.13. If the jack is not going to be in use, close the air supply and disconnect the supply hose.
3.14. After each use, check the components of the jack. If any anomaly is detected, rectify it.
4. MAINTENANCE
4.1. Both the maintenance and repair of this jack may only be carried out by qualified and authorized personnel.
4.2. Before performing any maintenance operation, disconnect the air supply hose from the connection (3, Fig.3) located in
the handle.
4.3. Clean and lubricate the moving parts of the jack at regular intervals and introduce a small amount of lubricant in the air
inlet connection. The whole jack should be kept clean and protected from aggressive conditions at all times.
4.4.
Oil Level
The pistons should be fully retracted prior to proceeding to check or refill the oil level. The oil level is correct
whet it is between the two marks on the rod. Refill as required in accordance with the volume indicated in the table.
4.5. If all of the oil needs to be replaced, position the jack between two supports so that the connecting tube (1, Fig.5) can be
removed through which the oil will flow and be collected in a container which will be handed over to an authorised agent.
Other methods may also be used to remove the oil: Using a pneumatic oil extractor, positioning the jack in a slanted
lateral position, removing the tank etc
4.6.
IMPORTANT
An excess of oil may affect the operation of the jack.
4.7. Only use hydraulic oil, HL or HM type, with an ISO grade of cinematic viscosity of 20cSt at 40ºC or of an Engler viscosity
of 2 at 50ºC.
4.8.
EXTREMELY IMPORTANT
Never use brake fluid.
4.9. Always use original parts. The use of non-original components may damage the jack and will invalidate the guarantee.
4.10. Damaged or illegible labels should be replaced with new ones.
4.11. Whenever the jack is not in use, the pistons should be fully retracted so as to reduce the risk of corrosion.
4.12. When ordering spare parts, please state the reference indicated in the general chart. Repair kits for the hydraulic set (X),
motor (Y) and offloading (Z) are available containing all the gaskets and seals.
