MAINTENANCE
Measurement of particle quantity
This uses a PQI (Particle Quantifier Index) measurer to
measure the quantity of large iron particles in the oil.
Others
Measurements are made of items such as the ratio of water or fuel in the oil, and the dynamic viscosity.
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.
For further details of KOWA, please contact your Komatsu distributor.
GREASE
Grease is used to prevent twisting and noise at the joints.
The nipples not included in the MAINTENANCE section are nipples used when overhauling, so they do not
need grease.
If any part becomes stiff or generates noise after being used for a long time, grease it.
Always wipe off all of the old grease that is pushed out when greasing.
Be particularly careful to wipe off the old grease in places where sand or dirt sticking in the grease would
cause wear of the rotating parts.
OIL AND FUEL STORAGE
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).
