MAINTENANCE
5. When all liquid has been drained, close the drain valve,
replace the drain plugs and hoses.
Coolant filling
1. Fill the expansion tank through the opening (2) to the
maximum level.
2.
Allow the coolant to fill the system (liquid level drop)
and refill the tank to the maximum level.
3. Repeat steps 1 and 2 until the coolant level has stabi-
lized at the maximum level.
4. Reinstall the pressure cap (2).
5.
Start the generator and let it run for a few minutes.
6.
Stop the generator and let it cool down. Check the
coolant level in the expansion tank and add coolant
if necessary.
CAUTION!
Do not start the engine without coolant. Use a mixture
of 50% clean, fresh, non-calcareous water and 50% anti-
freeze to fill the cooler.
CAUTION!
For the water-antifreeze mixture, the proportion of anti-
freeze should be 50%. Tighten the radiator cap securely. If
the cap is loose or not properly tightened, water may leak
out and the engine may overheat.
CAUTION!
Do not use antifreeze and scale inhibitor at the same time.
Never mix different types or brands of coolants or anti-
freeze. This coolant should be replaced every 2 years or
500 hours, whichever comes first.
ANTI-GEL
There are two types of antifreeze: use the permanent type
(PT) for this motor.
Before adding antifreeze for the first time, clean the inside
of the heat exchanger by pouring fresh, cool water and
draining it several times.
The procedure for mixing water and antifreeze differs de-
pending on the brand of antifreeze and the ambient tem-
perature.
In principle, the SAE J1034 standard should be referred to,
more precisely also the SAE J814c standard.
Mix the antifreeze with fresh fresh water and fill the heat
exchanger.
IMPORTANT!
When antifreeze is mixed with fresh water, the antifreeze
mixing ratio should be 50%.

* At a pressure of 1.013 × 100000 Pa (760 mmHg) (atmospheric pressure).
A higher boiling point is achieved by using a radiator cap that allows pres-
sure development in the cooling system.
IMPORTANT!
The above data represents industry standards that require
a minimum glycol content in the antifreeze concentrate.
IMPORTANT!
When the coolant level drops due to evaporation, add
fresh fresh water only so that the antifreeze mixing ra-
tio is less than 50%. If there is a leak, add antifreeze and
fresh water mixed in the specified ratio.
Antifreeze absorbs moisture. Store unused antifreeze in a
tightly sealed container.
IMPORTANT!
Do not use cleaning products when antifreeze has been
added to the coolant (antifreeze contains an anti-corrosion
agent, which will react with the cleaning product to form a
sludge that will affect engine parts).
