Dismount filter element as follows:
Lift hopper and place jackbar.
Open the lockings, remove separa-
tor (Fig. A/1) and clean from coarse
particles.
Dismount filter element.
Carefully blow-out the filter element
with dry compressed air (3bar max.)
by moving the pipe (Fig. B/1) up and
down in the filter element until dust
rising has finished. Replace heavily
soiled or damaged filter element.
Mount filter element, place separa-
tor and close lockings.
Note:
do not run the engine without fil-
ter element.
Engine and hydraulic
cooling system
a) drive engine
tthe cooling system is filled with a lon-
glife anti-freeze mix to preclude dama-
ges by corrosion or calcification and to
raise the boiling point of the water. For
this purpose, the coolant has to
remain in the system all over the year.
Due to its raising the boiling point of
the water the coolant guarantees ope-
rating safety at higher ambient tempe-
ratures and more important engine
loading. Before the cold season starts,
check coolant concentration and add
concentrate as required
to guarantee adequate anti-freeze pro-
perties.
Check coolant level in expansion tank
in regular intervals. The engine being
cold, coolant level in the expansion
tank has to read between min. and
max. marks. Engine being warm, level
will be higher.
Fill coolant:
Caution: hazard of scalding !
Never attempt to open cap while
engine is hot. Cooling system is pres-
surized!
To maintain proper antifreeze and
corrosion inhibiting properties and
to avoid calcification, never dilute coo-
lant in the warm season by filling pure
water. Filling capacity of the cooling
system is approx. 8 litres
Cooling air intake
Cooling air is aspired through an air
grille with screen located in the rear.
Check this screen for accu-mulated
dirt every day and clean as required.
Clean screen from both sides; also
clean bottom panel between screen
and radiator. Clean radiator with com-
presses air from time to time.
b) hydraulic installations
For correct function of all hydraulic
installations, protect the hydraulic oil
from overheating. For this purpose we
installed a separate radiator next to
the engine radiator and one common
fan supplying both radiators with fresh
air.
