Maintenance And Lubrication - Grillo FD 1100 4WD Emploi Et Entretien

21) CAUTION! Do not transfer the machine with lifted cutting deck. Use the cutting deck hydraulic lifter only to get
over obstacles, mount on pavements or on kerbs. It is compulsory, instead, to travel on public streets with a
type-approved machine, endowed with a lights system, a plate and with the cutting deck up.
MOWING POSITIONS
Use the hand wheel (fig. 1 n° 12 and fig. 12) to adjust the cutting height.
When working on rough terrain, with bumps or humps, it is best to use the deck in the highest cutting position to
avoid impact with the blade.
Attention! During the cut the deck lifting button has to be in the «floating» position.
SLOPING GROUND
Steep ground should be tackled in an up-and-down movement, being very careful at direction changes that the
wheels uphill do not meet any obstacles (stones, branches, roots, etc.) which could cause loss of control over the
machine. If the drive wheels tend to slip, use the hydraulic control to slightly raise the deck so that more weight is
exerted on the drive wheels, therefore giving more traction.
Evaluate the various conditions and be careful in the presence of damp ground and wet grass because this could
cause the mower to slide. When going downhill, start off at a slow speed and avoid driving over dry or cut grass
because the wheels could lose their grip.
The differential locking (fig. 1 n° 26) must be used only in special cases, for example: if during a strong descent you
want to reverse the direction of travel, to avoid the rear wheels skidding, or in case of load on motor vehicle in
reverse motion with the presence of ramps. Normally do not engage the differential locking.
Do not run any risks, check the ground carefully and if you do not feel safe, avoid strong slopes and do not exceed
the speed-limits, which are imposed by your country laws and written also in this manual (max. 18° or 32%).
SAFETY DEVICE TRIGGERING
Always remember that the engine stops each time when:
- the operator gets up from the seat, if the parking brake has not been engaged and the blades have not been
disengaged before.
In addition, the engine will not start if:
- the PTO switch is engaged;
- if there is no one seated on the driving seat, unless the parking brake has been engaged and the blades have
been disengaged before;
the feed pedals and the reverse pedal are not in the stop position;
-
- the grass catcher is not completely lowered.
Attention! When the parking brake is engaged, it is possible to leave the driving seat with the engine on, if the
blades are disengaged.
CAUTION!
Stop the engine and remove the ignition key before carrying out any cleaning, maintenance or repairs.
Always wear suitable working clothes and safety gloves.
If you do the maintenance on the engine, keeping the basket up, engage the two red painted security lockings on
the hydraulic cylinders (fig. 13). Never work on the engine if you have not engaged the lockings.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment!
Proper maintenance and correct lubrication help to keep the mower perfectly working.
ENGINE
For the lubrication intervals follow the directions given in the engine manual; it is in any case indispensable to
change the oil and the filter after the first 50 working hours and then every 250 hours. For the diesel engine
use SAE 15 W 40 oil, 5 litres. When you change the engine oil, it is necessary to change also the oil filter (fig. 14,
ref. B). To remove the engine oil, unscrew the lid on the right side of the oil cup. Pour in the oil trough the lid (fig.
33).
The first precaution to be taken is that the engine is maintained correctly with a clean air filter and the engine oil up
to the level. Keep the engine compartment, the muffler area and the collectors clean. Use a vacuum cleaner if
possible.
Check the air filter (fig. 9) and the prefilter (fig. 13) every 8 hours or even more frequently in dusty conditions.
In order not to reduce the air needed to cool the radiator, the grid must always be kept clear. Make sure the radiator
is always clean.
The radiator fan is driven by an electric engine. If the radiator protection grids are obstructed and the cooling fluid
and the hydraulic oil temperature gets over 88° C, a sensor automatically inverts the direction of rotation of the fan
for a few minutes in order to clean the grids. This operation can also be made by hand, working for a few second
the fan inverter button (fig. 1 n° 25). To check and clean the radiator fan, remove the pin (fig. 15, ref. A).
