Storing Oil And Fuel - Komatsu WA500-6H Operation & Maintenance Manual

Maintenance
Measurement of particle quantity
This uses a particle quantifier index measurement machine
to measure the quantity of iron particles of 5 µ or more,
enabling early detection of failures.
Others
Measurements are made of items such as the ratio of water
in the oil, density of the antifreeze coolant, ratio of fuel in the
oil, and dynamic viscosity, enabling a highly precise diagno-
sis of the machine's health.
Oil sampling
Sampling interval
250 hours: Engine
500 hours: Other components
Precautions when sampling

Make sure that the oil is well mixed before sampling.

Carry out sampling regularly at fixed intervals.

Do not carry out sampling on rainy or windy days when
water or dust can get into the oil.

tributor.

Storing oil and fuel

Keep indoors to prevent any water, dirt, or other impurities
from getting in.
When keeping drum cans for a long period, put the drum on
its side so that the filler port of the drum can is at the side to
prevent moisture from being sucked in.
If drum cans have to be stored outside, cover them with a
waterproof sheet or take other measures to protect them.
To prevent any change in quality during long-term storage,
be sure to use in the order of first in - first out (use the oldest
oil or fuel first).
