FD2200 stage 5/ Translation of the original instructions
- Engine at min. r.p.m.
- Push the manual regeneration button for 3 second, until the "regeneration needed" warning light flashes on
the dashboard (fig. 2, U).
- Push the manual regeneration button again for 1 second.
A manual regeneration cycle will be activated. Forced regeneration cycles can be activated at intervals of at
least 50 hours from the last one.
Regeneration blockage: During regeneration cycles, very high temperatures in the DPF can be reached.
When working in very dry and dusty environment, it could be useful to prevent the machine from initiating
automatic regeneration cycles. This function can be blocked via the switch on the dashboard (fig. 2, no. 12).
Should this switch be left pressed down, visual and acoustic warnings for a "regeneration needed" will be
active. Again, should these warnings be ignored until the soot loading in the filter gets over 16g/, an
emergency regeneration will take place.
AIR FILTER
Check the air filter every 8 hours or more frequently if the place where you use the machine is very dusty (fig.
8). The air filter is endowed with a depression sensor that signals with a warning light on the dashboard that
the filter is obstructed. For the substitution and the exact maintenance intervals please follow the instructions
and warnings in the engine manual. The air filter is also fitted with an inner safety cartridge.
GAS OIL FEEDING PUMP
There is an electric pump (fig. 18) in the gas oil feeding circuit that takes fuel from the tank and sends it to
the filter (see engine handbook).
DIESEL FILTER
Change the diesel filter cartridge (fig. 21, ref. A) every 250 hours, or more frequently if you notice impurities
in the container. Check the container at every use and empty it every 50 hours. For the substitution and the
exact maintenance intervals please follow the instructions and advices in the engine manual.
DIESEL DECANTING DEVICE
The decanting device (fig. 5, ref. B) makes it possible for liquid impurities in the diesel or water to deposit on
the ground so that they do not get in contact with engine parts. Clean the decanting device every 250 hours,
and also wash the inside of the lid with clean diesel. Check the decanting device at every use and empty it
every 50 hours. For the cleaning and the exact maintenance intervals please follow the instructions and
advices in the engine manual. Attention! When you fill up the diesel tank, always use a very fine filter.
RADIATOR REFILLING
If the liquid in the cooling circuit is running out, you have to refill it with the refilling cap on the expansion tank
on the right side of the driving seat: to uncover it, remove the black protection on top of the cowling (fig. 35).
Carry out this intervention with cold engine.
RADIATOR BLEED
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:
1)Caution! For this operation always wear suitable working gloves.
2)With the liquid in the reservoir at the right level, 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 reservoir.
4)Unscrew the plug for the bleed on the upper part of the radiator (fig. 36).
5)With the plug open, accelerate to medium speed and slow down several times until plain liquid comes out.
6)Tighten the screw.
7)Accelerate again for some minutes.
8)Unscrew the bleed plug again and repeat the steps 5-6-7 four or five times until plain liquid comes out.
9)At the end, re-establish the liquid level in the reservoir and close the cap.
HYDRAULIC ENGINES
Check the level in the reservoir with cold engines (fig. 4). If more oil is needed, add hydraulic oil OSO 46
(total quantity: 36 litres, fig. 6, ref. B). Carry out this control periodically.
Caution! Change the hydraulic oil in the hydraulic engines the first time after 500 hours and then every 1000
hours.
