the movement has been completed, place the
load on the ground. The crane is not a device
to maintain the load elevated for an unlimited
period.
11. As a safety measure against overload, the
crane is fitted with an overload valve, set at its
maximum working pressure at the factory. This
valve should not be tampered with under any
circumstances.
ASSEMBLY & OPERATION
As we are handling heavy elements, it is essen-
tial to carry out the following assembly process-
es with the help of other people.
1. Break the box and
assemble
the
wheel
brackets on the col-
umn.
2. Lift the crane and attach the hydraulic unit to
the arm using the provided axle. Make sure that
the rings are correctly placed.
3. Prior to using the crane, the hydraulic circuit
needs to be drained in order to eliminate any
air from the valve system of the hydraulic unit.
Turn
the
hydraulic
group knob 90º while
pumping the lever sev-
eral times. By releasing
the knob the crane is
ready for use. Turn the
hydraulic unit to work
in the most comfort-
able position.
4. To lift the load, activate the lever. If lifting an
engine, secure it at the points recommended by
the manufacturer.
5. If it is necessary to use the crane in other posi-
tions, the slide should be perfectly fitted.
6. To lower the load, turn the knob. This system
enables the lowering to be regulated and con-
trolled manually and precisely. As another safe-
ty element, the crane is fitted with an LCS sys-
tem to avoid brusque lowering, resulting from
a possible incorrect manoeuvre. The crane will
stop the lowering process when the knob is not
activated.

7. When the use of the crane is completed, the
piston of the hydraulic unit should be fully re-
tracted. First move the slide to its initial posi-
tion.
MANTENIMIENTO
IMPORTANT: Both the maintenance and re-
pair of this crane may only be carried out by
qualified and authorized personnel, who as a
result of their training and experience are fa-
miliar with the hydraulic systems used in these
devices.
1. Clean and lubricate the axes of the moving
parts of the crane at regular intervals. The crane
should be kept clean and protected from ag-
gressive conditions at all times.
2. Only original spare parts should be used.
3. Withdraw the crane from service if it is sus-
pected that it has been subjected to abnormal
loads or has suffered any type of knock until the
problem has been resolved.
4. If the oil level needs to be checked or refilled,
dismantle the hydraulic unit and with piston
fully retracted, remove the filler plug and drain
its contents into a container. With the hydrau-
lic unit in a horizontal position, proceed to in-
troduce the necessary volume for each model as
indicated. Avoid the entrance of any dirt with
the new oil.
IMPORTANT: An excess of oil over the vol-
ume required may affect the operation of the
crane.
5. Only use hydraulic oil, HL or HM type, with an
ISO grade of cinematic viscosity of 30cST at 40º,
or of an Engler viscosity of 3 at 50ºC.
EXTREMELY IMPORTANT: Never use brake
fluid.
6. When the crane is not in use, it should be fully
retracted in the lowest position so as to mini-
mize piston corrosion. It is recommendable to
apply an anti-corrosion product to the main pis-
ton and to the pump.
7. Store the crane in a dry and clean place, out
of the reach of children.
8. At the end of the useful life of the crane,
drain off the oil and hand it over to an autho-
rised agent. Dispose of the remaining parts in
accordance with local regulations.
9. Both the repair kit, which exclusively contains
the retainers and joints, and the spare part sets,
must be ordered using the reference assigned
in the table.
