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 SAE
15 W 40 oil, 6.5 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.
The radiator fan is driven by a hydraulic engine. 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, remove the pin (fig. 19).
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.
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 possible liquid impurities in the diesel or water 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.
