DX380LC-7

Grease

•

Grease is used to prevent seizure and noises at joints.

•

This construction equipment is used under heavy-duty
conditions. Always use recommended grease and follow
change intervals and recommended ambient temperatures
given in this manual.

•

Always wipe off all old grease that is pushed out when
greasing.

Wipe off old grease where sand or dirt sticking in the
grease can cause wear of rotating parts.

Coolant and Water for Dilution

•

The coolant has the important function of preventing
corrosion and preventing freezing.
Even in areas where freezing is not an issue, use of
antifreeze coolant is essential.
DOOSAN machines are supplied with DOOSAN coolant.
DOOSAN coolant has excellent anticorrosion, antifreeze
and cooling properties and can be used continuously for
1 year or 2,000 hours. Therefore, it is recommended to use
authorized genuine DOOSAN antifreeze solution.
When using DOOSAN coolant, there is no need to use a
corrosion resistor. For details, see "Engine Cooling
System" on page 4-91.

•

When diluting antifreeze coolant, use distilled water.
Natural water, such as a river water or well water (hard
water), contains large amounts of minerals (calcium,
magnesium, etc.), and this makes it easier for scale to form
inside engine or radiator. Once scale is deposited inside
engine or radiator, it is extremely difficult to remove.
If tap water needs to be used, refer to "Engine Cooling
System" on page 4-91 for further information on standards
and precautions. 

•

When using antifreeze, always observe precautions given
in this manual.

•

Antifreeze coolant is flammable, so be sure to keep it away
from any flame.

•

The ratio of DOOSAN coolant to water differs according to
ambient temperature.
For details of ratio when mixing, see "Antifreeze
Concentration Tables" on page 4-93.
DOOSAN coolant may be supplied premixed. Never add
distilled water.

•

If engine overheats, wait for engine to cool before adding
coolant.

•

If coolant level is low, it will cause overheating and
corrosion problems because of air entering coolant.
