RECOMMEND FUEL, COOLANT,
AND LUBRICANT
• Lubrication is an important part of preventive maintenance.
To keep your machine in optimum condition for long
periods of time, it is essential to follow the instructions set
forth in this manual.
• Failure to follow these recomm
endations can result in
shortened life or excess wear of the engine, power train,
cooling system, and/or other components.
• Commercially available lubricants can ca
use harm to the
machine. Use sparingly. DOOSAN does not recommend
any commercially available lubricant additive.
• When starting the engine in temperatures below 0°C
(32°F
), be sure to use the 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. Discuss with your
DOOSAN distributor.
• Only use Ultra Low Sulfur Diesel (ULSD) fuel and API CI-4/
ACEA E5, E7
or API CJ-4/ACEA E9 grade engine oil.
• If ULSD fuels are not available, the su
lfur contents of fuel
being used must be less than 15 ppm.
Lubrication
Lubrication is an important part of preventive maintenance. If the
machine is lubricated in the specified manner, the life of
equipment and components can be considerably extended. The
“Lubrication and Service Chart” on page 4-30 makes lubrication
work easier and reduces the risk of forgetting lubrication

IMPORTANT
Wipe off grease fittings and grease gun before greasing to
prevent sand and dirt particles from penetrating into
components.
