4.2.1 NOTES REGARDING THE ENGINE
4.2.1.1 ENGINE OIL
The engine oil must be selected very carefully, since it lubricates the engine, which is the machine's heart; the
q
main maintenance operations required for the engine oil are the following:
1 - daily check of the oil level;
2 - check of the degree of pollution of the oil;
3 - periodical change.
4.2.1.2 COOLANT
The coolant serves to keep the engine at the correct temperature and therefore to ensure optimal operating
q
conditions; check the coolant level in the expansion tank daily and top up when necessary.
The coolant containing antifreeze is flammable; do not use naked flames near the coolant and do not smoke
q
while topping up.
