Coolant refilling
For the initial engine start-up and in the cases in which the refilling of
the cooling circuit is required with a considerable quantity of coolant,
proceed as follows:
Refill the engine and the exchanger until the exchanger is
completely filled.
With the coolant filler plug open, start the engine and let it idle for
approx. 1 minute. This helps to completely bleed the air contained
in the cooling circuit.
Stop the engine and then top up with coolant if necessary.
Refuelling
Use only diesel oil in accordance with ASTM D975 or EN 590
standard normally commercially available. Fuel additives are not
recommended.
Use of additives can limit the guarantee performance offered for the
equipment.
Low temperature diesel
At low temperatures the degree of fluidity of the diesel can become
low due to the separation of the paraffin resulting in the filters
becoming clogged.
ASTM D975 or EN590 specifications distinguish different classes of
diesel fuel, identifying the characteristics of those best suited to low
temperatures.
It is entirely up to the Oil companies to comply with these regulations,
which foresee that fuels suited to the climactic and geographic
conditions of the various Countries be distributed.
The failure to observe the aforesaid procedure does not
guarantee the presence of the correct quantity of
coolant in the engine.
CAUTION!
When the engine is hot, pressure builds up in the
cooling circuits which may eject hot liquid violently,
resulting in a risk of burns. Open the filler cap of the
coolant tank only if necessary and only when the
engine is cold.
CAUTION!
Pay maximum attention when refuelling, making sure
that solid or liquid pollutants do not enter the tank;
please remember that smoking is prohibited while
refuelling. The couplings of the fuel circuit under high
pressure must not be loosened under any
circumstances.
