Lubricant
•
Lubrication is an important part of preventive maintenance.
To keep your machine in the best condition for long periods
of time, it is essential to follow the instructions given in this
manual.
•
Failure to follow these recommendations can result in
shortened life or excess wear of the engine, power train,
cooling system, and/or other components.
•
Commercially available lubricant may be good for the
machine, but it can also cause harm. DOOSAN does not
recommend any commercially available lubricant additive.
•
When starting the engine in temperatures below 0°C
(32°F), be sure to use recommended multigrade oil, even if
the ambient temperature may become higher during the
course of the day.
•
If the machine is operated at temperatures below -20°C
(-4°F), a separate device is needed, so discuss with
DOOSAN distributor.
•
Only use Ultra Low Sulfur Diesel (ULSD) fuel and API CJ-
4/ACEA E9 grade engine oil.
Lubrication
Lubrication is an important part of preventive maintenance. If the
machine is lubricated in a specified way, the life of equipment
and components can be considerably extended. The
"Lubrication and Service Chart" on page 4-14 makes lubrication
work much easier and reduces the risk of forgetting lubrication
intervals.
NOTICE
Wipe off grease fittings and grease gun before greasing to
prevent sand and dirt particles from penetrating into
components.
