Unless specified otherwise, the oils and the coolant used by Komatsu to fill the tanks before the delivery of the
machine are the following:
OIL, FUEL, COOLANT AND GREASE 4
Oil 4
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
indicated in the use and maintenance manual. Change the oil after the prescribed interval, even if it is not dirty.
q
The oil is for the machine what blood is for the human body: therefore prevent the entry of impurities (water,
metal particles, dirt, etc.).
Most machine problems are caused by the entry of impurities.
Be careful not to let impurities enter when changing or topping up the oil.
q
Do not mix different types or brands of oil.
q
Maintain the prescribed levels when topping up the oil.
Too much or too little oil can cause malfunctions.
q
If the oil in the working equipment is not clear, there is probably water or air in the circuit. Contact Komatsu
distributor.
q
When changing the oil, change also the filters.
