Maintenance And Lubrication - Grillo FD 2200 stage 5 Manuel D'utilisation

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 basket up, engage the two red painted security locks
on the hydraulic cylinders (fig. 15). Never work on the engine if you have not engaged the locks.
ENGINE
For 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 15W40 (API CJ-4) oil, 4,8 litres (fig.16 and fig. 17). When you change the engine oil, it is
necessary to change also the oil filter (fig. 46) and the gas oil filter (fig. 21, ref. A). 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. 8) and the pre-filter 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. If the radiator protection grids are obstructed and the cooling fluid and the hydraulic oil
temperature gets over 92° 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. 2 no. 5). To check and clean the radiator fan, detach the lever (fig. 19, A).
DPF FILTER (Diesel particulate filter)
The Yanmar engine 3TNV88C is equipped with a particulate filter (fig. 56), according to the current laws. For
cleaning and maintenance schedule, please refer to the engine manual.
DPF REGENERATION
Automatic regeneration: when the soot loading in the filter reaches the set limit of 8g/l, the machine will
start an automatic regeneration. The warning light of the "regeneration needed" on the dashboard switches
on (fig. 2, T). The machine is fully operational and the operator can therefore keep on working.
Manual regeneration: should the automatic regeneration not be sufficient to thoroughly clean the DPF, the
warning light on the dashboard switches of if the soot loading reaches the set limit of 8g/l (fig. 2, U). When
this warning light is on, a manual regeneration is needed. Follow the instructions below:
- Engine temperature higher than 60°
- Parking brake engaged
- Engine at min. r.p.m.
- Push the manual regeneration button for 1 second.
Once this procedure has been carried out, a warning light of "regeneration currently underway" switches on
on the dashboard (fig. 2, T), indicating that the manual regeneration of the DPF has been initiated. It takes
about 20 minutes to complete a manual regeneration cycle. Should the manual regeneration button be
accidentally pressed down when the "regeneration needed" warning light is not on, the regeneration cycle
won't activate. The operator can also keep on working, ignoring the "regeneration needed" warning light. It
will be then signalled again that a regeneration cycle is needed.
Emergency regeneration: Should the warnings of "regeneration needed" be constantly ignored by the
operator until the soot loading in the filter gets over 16g/l, the lawnmower reduces the engine power of 50%.
To restore the functions of the machine, it is necessary to initiate a manual regeneration. In this specific
case, the regeneration cycle will last about two hours.
Forced regeneration: this option is normally used in case of rental machines. To prevent the customer from
facing and emergency regeneration during work, a forced regeneration cycle is initiated by the dealer before
renting the machine. Follow the instructions below
- Engine temperature higher than 60°
- Parking brake engaged
