OPENING OF THE FRONT BONNET
Opening of the bonnet:
Unlock the bonnet by pressing the
pushbutton (1) and lift it in places of the
arrows.
The bonnet is kept in lifted position using
a gas-fluid strut.
Closing of the bonnet:
Take the bonnet in places of the arrows
and press it down until the lock clicks.
Rapid closing of the bonnet may
damage filaments of the headlamp bulbs in the front bonnet.
MAINTENANCE OF THE DRY AIR
CLEANER – INDICATOR OF
CLOGGING
Maintenance of the cleaner shall
be carried out when clogging is
indicated.
The indicator is accessible after tilting of
the engine front bonnet. It can be found
on the left side of the air cleaner, close to
the suction pipe elbow.
FUNCTION OF THE INDICATOR OF
CLOGGING
The level of clogging of the air filter is indicated by position of the slider (1) in the
window. In case the indicator (1) reaches
the red field service (2), it is necessary
to carry out maintenance of the dry air
cleaner.
After completion of maintenance
of the dry air cleaner restore correct function of the indicator of
clogging.
Press the lid on the indicator body (3) in
direction of the arrow; this unlocks mechanically the slider (1) that returns to its
initial position and restores function of
the indicator.

OF THE AIR CLEANER
Carry out this operation in the reverse
order.
When re-installing the cartridges, pay attention to the following.
- cleanness of the contact surfaces,
- the cartridges must not be deformed
and must not vibrate after installation;
- perfect tightness of the whole air
cleaner shall be ensured after closing
the cover;
- After completion of maintenance of the
dry air cleaner restore correct function
of the indicator of clogging.
OIL TANK OF HYDROSTATIC
STEERING
The tank is installed in the left side of the
tractor and accessible after lifting of the
front bonnet.
Using the oil-gauge rod (A) check level
of oil in the hydrostatic steering tank;
keep the level between the marks MIN.
and MAX., see Fig. (A).
