12.10.HYDRAULIC OIL LEVEL CHECK
The check must be carried out with the machine and the stabilisers in the re‐
sting position on flat ground.
Fig. 161 Hydraulic oil level indicator
Check the oil level on indicator; the oil must be half way up the level indicator. If
this is not the case, top up through the relative cap. For the characteristics of the
hydraulic oil to be used see the relative paragraph ʺTable of recommended lbrifi‐
cants (p. 138)ʺ.
12.11.CHECKING FOR LEAKS IN THE HYDRAULIC SYSTEM
Visually check all hoses, connections and all other components in the hydraulic
system, in order to identify any possible leaks. Leaks from hoses can normally be
resolved by tightening the fittings. Leaks from gaskets (O rings, sealing rings etc.)
cannot be eliminated by simply tightening, as gaskets usually leak because they
are damaged or have become hard. The correct tightness can only be restored by
replacing the gasket.
12.12.CHECKING THE CONDITION OF THE FILTER CARTRIDGE
The cartridge must be replaced on every oil change and according to the intervals
specified in the maintenance table.
