OUTLINE OF OIL, FUEL, COOLANT

OIL
Oil is used in the engine and work equipment under extremely severe conditions (high temperature, high pres-
sure), and is deteriorates with use.
Always use oil that matches the grade and temperature for use given in the Operation and Maintenance Man-
ual.
Even if the oil is not dirty, always change the oil after the specified interval.
Oil corresponds to blood in the human body, so always be careful when handling it to prevent any impurities
(water, metal particles, dirt, etc.) from getting in.
The majority of problems with machine are caused by the entry of such impurities.
Take particular care not to let any impurities get in when storing or adding oil.
Never mix oils of different grades or brands.
Always add the specified amount of oil.
Having too much oil or too little oil are both causes of problems.
If the oil in the work equipment is not clear, there is probably water or air getting into the circuit. In such cases,
please contact your Komatsu distributor.
When changing the oil, always replace the related filters at the same time.
We recommend you to have an analysis made of the oil periodically to check the condition of the machine. For
those who wish to use this service, please contact your Komatsu distributor.
FUEL
The fuel pump is a precision instrument, and if fuel containing water or dirt is used, it cannot work properly.
Be extremely careful not to let impurities get in when storing or adding fuel.
Always use the fuel specified in the Operation and Maintenance Manual.
Fuel may congeal depending on the temperature when it is used (particularly in low temperature below -15ºC
(5ºF)), so it is necessary to change to a fuel that matches the temperature.
To prevent the moisture in the air from condensing and forming water inside the fuel tank, always fill the fuel
tank after completing the day's work.
Before starting the engine, or when 10 minutes have passed after adding fuel, drain the sediment and water
from the fuel tank.
If the engine runs out of fuel, or if the filters have been replaced, it is necessary to bleed the air from the circuit.
