• Retract the bucket and arm cylinder completely, lower the
bucket teeth to the ground and, after stopping the engine,
release the residual pressures from the work equipment
circuits (by operating the controls more than once) and
from the tank (by slowly loosening the filling cap).
• Let the oil cool down until it reaches 4045°C before carry-
ing out any maintenance operation.
• Immediately clean any area dirty with oil.
1 - Rotate the upper structure of 45°, in such a way as to leave
the lower part of the hydraulic oil tank free from the tracks.
2 - Retract the bucket and arm cylinder completely and lower the
boom until the bucket teeth touch the ground.
3 - Lower the blade to the ground.
4 - Stop the engine and eliminate the residual pressures present
in the equipment (by moving the controls several times).
5 - Slowly loosen the filling cap (1) in order to release the residu-
al pressure that may be present in the tank.
Use a 24 mm hexagon spanner.
6 - Remove the drain plug (2) until the condensate has flown out
of the tank completely.
Use a 32 mm spanner.
7 - Put back the filling cap (1).
IMPORTANT
☞
• The draining of the tank must be carried out at tempera-
tures exceeding 0°C, before starting the engine; when the
temperature is below 0°C, the hydraulic oil tank must be
drained at the end of work, or in any case when the tem-
perature of the machine is sufficiently high to prevent the
condensate from freezing and allow it to flow out of the
tank without problems.
