MAINTENANCE PROCEDURE
4.8.8.d
DRAINING THE HYDRAULIC OIL TANK
(Only for machines filled with synthetic
biodegradable oil type HEES)
Lower the loader arm completely, rest the bucket on to
q
the ground and, after stopping the engine, eliminate the
residual pressures that may be present in the equip-
ment (by operating the controls more than once) and
lock the safety bars (see "3.3.5
BARS").
Let the oil cool down until it reaches 40-45ºC before per-
q
forming any maintenance operation.
Immediately clean any area dirty with oil.
q
Stop the machine on a firm and level surface, lower the equip-
ment to the ground, stop the engine and release the residual
pressures that may be present in the equipment by operating
the controls more than once.
Raise the engine hood (see "3.5.1 ENGINE HOOD") and open
the rear panel (see "3.5.2 REAR PANEL").
1 - Slowly loosen the filling cap (1) to release the residual
pressure from the tank and remove it.
2 - Loosen the lower plug (2) until the condensate has flown
out of the tank completely.
Use a 12 mm hexagon spanner.
3 - Put back the lower plug (2), the filling cap (1) and close
the rear panel and the engine hood.
IMPORTANT
The draining of the tank must be carried out at tempera-
q
tures exceeding 0ºC, before starting the engine; when
the temperature is below 0ºC, the hydraulic oil tank must
be drained at the end of work, or in any case when the
temperature of the machine is sufficiently high to pre-
vent the condensate from freezing and to allow it to flow
out of the tank without problems.
