OUTLINE OF MAINTENANCE
• Komatsu recommends using Komatsu genuine parts for replacement parts, grease or oil.
• When changing the oil or adding oil, do not mix different types of oil. When changing the type of oil, drain all
the old oil and fill completely with the new oil. Always replace the filter at the same time. (There is no prob-
lem if the small amount of oil remaining in the piping mixes with the new oil.)
• Unless otherwise specified, when the machine is shipped from the plant, it is filled with the oil and coolant
listed in the table below.

HANDLE OIL, FUEL, COOLANT, AND PERFORMING OIL CLINIC
OIL
• Oil is used in the engine and hydraulic equipment under extremely severe conditions (high temperature,
high pressure), and deteriorates with use.
Always use oil that matches the grade and maximum and minimum ambient temperatures recommended in
Operation and Maintenance Manual.
Even if the oil is not dirty, always change the oil at the specified interval.
• Oil corresponds to blood in the human body, always be careful when handling it to prevent any impurities
(water, metal particles, dirt, etc.) from getting in.
The majority of failures with the 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 failures.
• If the oil in the work equipment is not clear, there is probably water or air getting into the circuit. In such
cases, consult your Komatsu distributor.
• When changing the oil, always replace the related filters at the same time.
• We recommend that you have an oil analysis periodically to check the condition of the machine. For those
who wish to use this service, consult your Komatsu distributor.
• When using commercially available oil, it may be necessary to reduce the oil change interval.
We recommend you to use the Komatsu oil clinic to check the characteristics of the oil in detail.
FUEL
• To prevent the moisture in the air from condensing and forming water inside the fuel tank, always fill the fuel
tank with fuel after completing the day's work.
• The fuel pump is a precision equipment, 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 for the temperature that is described in Operation and Maintenance Manual.
• If the fuel is used at the temperatures lower than the specified temperature (particularly at tempera-
tures below - 15 °C {5 °F} ), the fuel will solidify.
