HANDLING OIL, FUEL, COOLANT, AND PERFORMING OIL CLINIC

OIL
Oil is used for the engine and hydraulic equipment under extremely severe conditions (high temperature,
high-pressure), so the oil deteriorates with use.
Always refer to the Operation and Maintenance Manual and use the recommended oil that matches the grade
(class) and maximum and minimum ambient temperatures.
Even if the oil does not appear to be dirty, always change it after 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 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.
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 periodic performance of the oil clinic to ensure that you always know the condition of the
machine. Please contact your Komatsu distributor for details of the oil clinic.
When the machine is shipped from the factory,T010 (power train oil) is used for the hydraulic system.
When using H046-HM hydraulic oil, drain all the oil and fill with the specified amount of oil.
Always use oil recommended by Komatsu. If any other oil is used, it will cause clogging of the filter.
There is no problem if the new oil is mixed with the small amount of oil remaining in the piping and cylinders.
