Storing Oil And Fuel - Komatsu PW130ES-6K Operation & Maintenance Manual

MAINTENANCE.
The proportion of anti-freeze to water differs according to the
G
ambient temperature.
For details of the mixing proportions, see "CLEAN
INSIDE OF COOLING SYSTEM" on page 189.
If the engine overheats, wait for the engine to cool before
G
adding coolant.
If the coolant level is low, it will cause overheating and will
G
also cause problems with corrosion from the air in the cool-
ant.
GREASE
Grease is used to prevent twisting and noise at the joints.
G
The nipples not included in the maintenance section are nip-
G
ples for overhaul, so they do not need grease.
If any part becomes stiff after being used for long time, add
grease.
Always wipe off all of the old grease that is pushed out when
G
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.

STORING OIL AND FUEL

Keep indoors to prevent any water, dirt, or other impurities
G
from getting in.
When keeping drum cans for a long period, put the drum on
G
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
G
sure to use in the order of first in first out (use the oldest oil or
fuel first).
FILTERS
Filters are extremely important safety parts. They prevent
G
impurities in the fuel and air circuits from entering important
equipment and causing problems.
Replace all filters periodically. For details, see the Operation
and Maintenance Manual.
However, when working in severe conditions, it is necessary
to consider replacing the filters at shorter intervals according
to the oil and fuel (sulphur content) being used.
Never try to clean the filters (cartridge type) and use them
G
again. Always replace with new filters.
When replacing oil filters, check if any metal particles are
G
stuck to the old filter. If any metal particles are found, please
contact your Komatsu distributor.
