the oil quantity and type, see the engine manual
(usually 15W/40).
- Periodically check the level of the hydraulic oil
through the oil sight glass on the side of the ma-
chine (1 Fig. 6). A proper level must be shown in the
midline of the sight glass when the machine is cold
and placed on a flat surface. If necessary, top up
with oil of the same type of the original equipment:
HYDRAULIC OIL AGIP ARNICA ISO 46, through the
filter cap placed over the oil tank (2 Fig. 6).
5.3.2 REPLACING THE HYDRAULIC OIL
- Every 500 hours
, perform the complete replace
-
ment of the hydraulic oil (total amount: 18/20
liters), possibly using the same type of oil or oil
with other characteristics equal to or greater than
the ones of the current oil.
Drain the oil in the tank causing it to flow from
the drain plugs (7 Fig. 6), one for each side of the
machine.
During this operation, put an oil collection tray
under the drain plug. Dispose of the oil in accord-
ance with the regulations. To drain all the oil from
the tank, tilt the machine sideways on both sides.
For the introduction of the new oil:
- Screw the drain plugs (7 Fig. 6);
- Remove the three screws that secure the cover (6
Fig. 6) and remove the lid;
- Unscrew the cap (2 Fig. 6) placed on top of the
filter (4 Fig. 6); replace the filter cartridge (3 Fig.
6). Introduce the new oil from the filter (4 Fig. 6)
through the cartridge just replaced.
- Use only original filter cartridges with filtration of 25
micon and oil already filtered at least at 10 microns.
5.3.3 TRACKS (ALIEN 5.0 - FIG. 9)
TENSIONING THE TRACKS
To return the tracks to the right tension, in the case
where after several hours of work «elongated»:
- Loosen the lock nut (2).
- Tighten the screw (1) until a proper tension of the
tracks (tracks must have the possibility to oscillate
about 4 cm as shown in Figure 9).
- Screw the nut (2) to obtain the full locking screw.
REPLACING THE TRACKS
For the replacement of the tracks, an operation that
will be performed very rarely, you may want to turn
to a fully equipped workshop that has an adequate lift
table and should have the ability to lift the machine,
freeing the tracks (via strains placed under the frame ).
This operation goes effectued when the tracks have
increased wear.
Disassembly of the tracks can be done if you have
to perform maintenance on the machine that require
disassembly.
To remove the tracks, perform the operations below
on each track:
- Loosen the nut (2) and unscrew the screw (1) until
the forks (3), with the idler wheels (4) move back
and lean frame.
- Remove the track from the driving wheels and
tension (5) and then from the machine.
- Enter the new track fitting it on the drive wheels (5)
and the wheels tensioning (4) the track (be careful
while matching the teeth with the central pitches
present inside the track), so, that once pulled, trac
-
tion is assured.
- Reaching the track screwing the tensioning screw
(1) and, once reached the correct tension (must
have the possibility to oscillate about 4 cm as
shown in the figure), with the lock nut (2). Meas

urement track 180x60x38.
5.3.4 TRACKS (ALIEN 6.5 - FIG. 10)
TENSIONING THE TRACKS
In this model of machine, the proper track tension
is automatic through the special springs (2 Fig. 10)
on each side.
REPLACING THE TRACKS
This operation must be performed when the tracks
have increased wear.
Disassembly of the tracks can be done if you have
to perform maintenance on the machine that require
disassembly.
To remove the tracks, perform the operations below
on each track:
- Loosen the nut (3) and remove the protection of
the thread and washer.
- Screw the nut supplied with each machine on the
M20 thread protruding from the spring.
- With the special wrench (provided), tighten the nut
until the fork that leads the wheel tensioning the
track comes to a stop.
- Now, you can remove the track to be replaced
and install the new one (dimensions of the track:
180x60x40).
- Enter the new track fitting it on the drive wheels and
