•
The level must be checked with running engine and trans-
mission oil at operating temperature; be very careful, in
order to avoid burns.
•
Let all the work equipment safety locks engaged, apply
the parking brake and do not move the gearshift lever.

If it is necessary to add oil, stop the engine before open-
ing the engine hood.
The dipstick (1) can be reached after opening the engine hood.
See “3.5.1 ENGINE HOOD”.
The oil level must be checked with the engine idling and the oil at
running temperature.
