Hydraulic drive
WARNING!
Before proceeding to any kind of maintenance work, make sure all lights on
the control panel are off, the power switch is in the OFF position, and the unit is
disconnected from the power supply.
Never open the electrical console when the unit is
connected to the power supply.
The hydraulic motor operates under pressure. Do not
release any connection or perform repair or maintenance work on components subjected
to pressure until all pressures have been eliminated.
The hydraulic motor should be serviced every year. To do this, proceed as follows:
a) Depressurize the unit and disconnect it from the power supply. Clean the cap of the
hydraulic tank to prevent extraneous matter from falling into the tank during removal of
the hydraulic components.
b)
Dismount and replace the tank’s return filter.
c) Inspect the bottom of the tank through the filter housing to check for the presence of
sediment. If sediment is present, empty the tank completely through the purge hole
located on its side.
WARNING!
Do not mislay the purge hole cap or gasket! Without either of these
components you will be unable to refill the tank.
Clean the interior of the pump intake and drain tubes located inside the tank.
Clean the bottom of the tank, eliminating all sediment.
d) Place the return filter in its operating position.
e) If the tank has been emptied, or if it needs more oil, fill it up as required.
WARNING!
Bear in mind the recommendations on oil (see p.22).
f) Check that the hydraulic pump is full of oil and make sure coupler connections are tight
enough for normal operation.
