warning:
the use of oil that does not conform to the technical specifications on chapter 9 will cause serious damage to
the engine and invalidate the guarantee.
when supplying the engine never ingest oil, fuel, coolant liquid, etc.. these substances are harmful to the
personal health of the user if ingested
4.2.2 FILLING THE COOLING CIRCUIT
As a refrigerating liquid, an anti-freeze of the brand
KRAFFT ACU
2300 CC 50% Ref. 1325
or another one with similar specifications
must be used.
The incorrect use of water in the refrigeration circuit is extremely
harmful, causing corrosion and scaling, while the use of anti-freeze
protects the circuit from corrosion, scaling and from freezing in
conditions of very low temperature, thus optimizing engine
maintenance and reliability.

warning!
do not allow AC88 liquid to come into contact with the eyes or the skin
warning!
do not ingest any of the liquids utilized to fill the various circuits on the engine
When distilled water is used in the refrigeration circuit, an anti-freeze product must be added, otherwise the expansion of
water when it freezes may produce cracks and damage to the refrigerator unit and to the block, and in proportion to the
temperatures expected.
The anti-freezing agent manufacturer, in the package labels is giving the instructions to be followed at each case.
However, in the following box, suitable rates a reset out in accordance with temperatures:
Ant freezing liquid concentration ( %)
30
40 50 60
Freezing temperature (ºC)
-10
-20 -30 -45
It is advisable the anti-freezing agent strength is selected based on a temperature which is approx. 5ºC under the actual
atmospheric temperature.
The anti-freeze solution recommended can be used fora normal operation of 2 years. At the end of this period of time the
refrigeration circuit must be emptied and cleaned, then refilled with the predetermined anti-freeze (see 4.2.2).
