5.2 Basic maintenance guidelines
 Exclusively use Komatsu genuine parts, greases and oils.
 When changing the oil or adding oil, do not mix different types
of oil. When changing the type of oil, drain the oil completely
and refill the system with the new oil. Also be sure to replace
the oil filter. (There is no problem if the small amount of oil
remaining in the piping mixes with the new oil.)
 Unless specifically required otherwise, the machine is deliv-
ered with fuel, coolant, and lubricants as shown in the table
below.
5.2.1 Fuel, coolant and lubricant specifications
Oil
 Oil is used in the engine and in the work equipment under
extremely severe conditions (high temperature, high pres-
sure) and deteriorates with use.
Always use oil that matches the grade and temperature range
specified in the Operation and Maintenance Manual.
Even if the oil is not contaminated, it needs to be changed
after the specified interval.
 Oil in a machine corresponds to the blood in a human body.
Handle it carefully to prevent contamination (water, metal par-
ticles, dirt, etc.).
The majority of problems with machines are caused by such
impurities.
Take particular care to prevent contamination during storage
or when refilling.
 Never mix oils of different grades or brands.
