OIL
Oil is used in the engine and work equipment under extreme
●
severe conditions (high temperature, high pressure), and it
deteriorates with use.
Always use oil that matches the grade and temperature for
use given in the Operation and Maintenance Manual. Even if
the oil is not dirty, always replace the oil after the specified
interval.
Always be careful when handling oil to prevent any ingress of
●
impurities (water, metal particles, dirt, etc.).
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 prob-
lems.
If the oil in the work equipment is not clear, there is probably
●
water or air getting into the circuit. In such cases, please con-
tact your Komatsu distributor.
