For filling the radiator liquid, use the filling cap on the radiator.
DANGER: to fill the fuel and the radiator liquid, turn off the engine; before
carrying out any operation let the engine be cooled.
8.6 HYDRAULIC CIRCUIT MAINTENANCE
a. Change the hydraulic oil after 500 working hours and, thereafter, every 1500 hours (or in any case every
year).
b. To discharge the exhaust hydraulic oil, use the suitable tap in the tank (tab.5, pos. 3).
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 (tab. 5, pos. 3).
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
µ
µ µ
µ
m filter.
d. Replace the filter cartridge (table 5, pos. 2) after 500 working hours and, thereafter, every 1500 hours (or
every year at least).
e. Daily check the clogging of the oil filters.
If necessary, replace the cartridges taking care of the following filtering grade:
⇒
intake filters for overfeeding pump: 10 µ (nominal values)
⇒
intake services filter (plunged in the hydraulic oil tank): 90 µ (nominal values)
For further maintenance operations of installed hydraulic components (pumps and motors), refer to the
enclosed documentation.
8.7 REDUCTION GEAR – STATIONARY BRAKES MAINTENANCE
a. Change the oil of the reduction gear, of the stationary brake of the reel winder and of the coupler after 50
working hours and, thereafter, every 500 hours (or every year at least).
b. To discharge the exhaust oil of the reduction gear and of the stationary brake, use the suitable caps on the
lower part of the casing.
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.
