Maintenance And Lubrication - Grillo FD 1100 4WD Manual De Montaje, Uso Y Mantenimiento

The differential locking (fig. 1 n° 26) is automatically engaged, 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 lock button (fig. 37).
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 DEVICES
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!
- Before performing any cleaning, maintenance or repair operation always wear suitable clothing and
working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always remember to use
suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without safety locks or
supports, never leave it unguarded in places where inexperienced people and children could have easy
access to it.
- Protect the environment: carefully dispose of used oils and any other pollutant product!
- Proper maintenance and correct lubrication help to keep the machine fully efficient.
If you do the maintenance on the engine, keeping the grass catcher up, engage the two red painted security locks
on the hydraulic cylinders (fig. 13). Never work on the engine if you have not engaged the locks.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment!
ENGINE
For the lubrication intervals follow the directions given in the engine manual; it is in any case necessary 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. 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, activating for a few second the fan inverter button (fig. 1 n° 25).
To check and clean the radiator fan, use the lever (fig. 15, ref. A).
RADIATOR REFILLING AND PURGE
Caution! Danger: hot liquid under pressure.
In order to let the engine cool down correctly, there should be no air in the cooling circuit. Make sure that the
clamps on the water muffs are well tight and that no air can get into the circuit from the outside.
Make the air bleed in the following way:
Caution! For this operation always wear suitable working gloves.
1) Fill in the liquid in the expansion tank fig. 7
2) Start the engine and bring it to working temperature (to make sure the engine thermostatic valve is open).
3) With the engine at minimum, open the engine cooling liquid refilling bowl on the right side of the driving seat
(fig. 7).
