4.2 MAINTENANCE NOTES
q
Use only Komatsu genuine spare parts.
q
Do not mix different types of oil.
q
Unless specified otherwise, the oils and the coolant used by Komatsu to fill the tanks before the delivery of the
machine are the following:
4.2.1 OIL, FUEL AND COOLANT
4.2.1.1 OIL
q
The oil used for the engine and the work equipment is subjected to demanding conditions (high temperature,
high pressure) and deteriorates with use. Always use oil suitable for the characteristics and temperatures indi-
cated in the use and maintenance manual. Change the oil after the prescribed interval, even if it is not dirty.
q
The engine oil must be selected very carefully, since it lubricates the engine, which is the machine’s heart; the
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.
q
When changing the oil, change also the filters.
q
It is advisable to have the oil periodically analysed in order to check the conditions of the machine. The analysis
must be carried out by specialized personnel at Komatsu Distributors.
