7.6 HYDRAULIC CIRCUIT MAINTENANCE
a. Change the hydraulic oil after 500 working hours and, then, every 1500 hours (or in any case every
year).
b. To discharge the exhaust hydraulic oil, use the suitable tap (table 1, pos. 13) on the bottom of the
tank.
DANGER: let the hydraulic oil be completely cooled before removing it and always use the
suitable safety wears (gloves, etc.).
ATTENTION: the discharge of the exhaust oils has to be effectuated in conformity with the
laws in force in the relevant country.
c. Fill the oil in the tank by means of the suitable filler (table 1, pos. 8).
ATTENTION: make maximum care when filling to make sure no foreign matter, which could
cause irreparable damages to the circuit’s components, enters along with the oil; if possible
filter the oil with a 10

m filter.
d. Replace the filter cartridges (table 2, pos. 5 and 6 and 16
– optional) after 500 working hours and,
then, every 1500 hours (or every year at least).
e. Daily check the clogging of the oil filters by means of the suitable indicators (table 3, pos. 24 and 25)
on the control panel. If necessary replace the cartridges taking care of the following filtering grade:

intake filter (table 2, pos. 5): 10 µ (nominal values)

intake filter (table 2, pos. 6): 90 µ (nominal values)

intake filter (table 2, pos. 16): 25 µ (nominal values) (optional)
For further maintenance operations of installed hydraulic components (pumps and motors), refer to the
enclosed documentation.
7.7 REDUCTION GEAR MAINTENANCE
a. Change the oil of the reduction gear after 50 working hours and, then, every 500 hours (or every
year at least).
b. To discharge the exhaust oil of the reduction gear, use the suitable caps on the lower part of the
casing of the same.
DANGER: let the hydraulic oil be completely cooled before removing it and always use the
suitable safety wears (gloves, etc.).
ATTENTION: the discharge of the exhaust oils has to be effectuated in conformity with the
laws in force in the relevant country.
c. Fill the oil of the reduction gear by means of the suitable caps on the upper part of the casing of the
same.
ATTENTION: make maximum care when filling to make sure no foreign matter, which could
cause irreparable damages to the circuit’s components, enters along with the oil.
