HYDRAULIC OIL TOP UP
The hydraulic oil tank is slightly under pressure at
about 0.3 bar (4 psi).
As mentioned previously, before performing any top
up of the hydraulic oil, it is important to relieve the
residual pressure inside of the hydraulic system.
Unscrew the screws (1) paying attention to cover (2)
that is under the spring (4) pre-load.
Reassemble the cover (2) with the spring (4) and
the gasket (3).
In the filter housing can now be seen the return filter
(5).
The top up has to be performed by letting the oil flow
though this filter, until the oil level sets between ref-
erences “min” and “max” of dipstick.
Before replacing the cover (2), check the gasket (3).
If this is damaged, replace it.
Reassemble the cover (2) with the gasket (3) and
the spring (4).
