Maintenance And Lubrication - Grillo FD13.09 Uso Y Mantenimiento

or on kerbs. It is compulsory to travel on public highways with a type-approved machine, fitted with a lighting
system, a nameplate and with the cutting deck raised.
MOWING POSITIONS
Use the button (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 when driving uphill, 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 lock (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 when loading onto a vehicle in reverse using
ramps. Normally do not engage the differential lock button (fig. 37). Do not run any risk, 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 forward and reverse pedals 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
15W40 oil quantity 3,6 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 through 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
