q
Always use Komatsu genuine parts for replacement parts, grease or oil.
q
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 problem
if the small amount of oil remaining in the piping mixes with the new oil.)
q
Unless otherwise specified, when the machine is shipped from the factory, it is filled with the oil and coolant
listed in the table below.

q
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
the Operation and Maintenance Manual. Even if the oil is not dirty, always change the oil at the specified inter-
val.
q
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 problems 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.
q
Never mix oils of different grades or brands.
q
Always add the specified amount of oil.
Having too much oil or too little oil are both causes of problems.
q
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.
q
When changing the oil, always replace the related filters at the same time.
q
We recommend you 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.
q
When using commercially available oil, it may be necessary to reduce the oil change interval.
We recommend that you use the Komatsu oil clinic to carry out a detailed checks of the characteristics of the
oil.
