Only use the engine coolant specified. Other engine
coolants may affect warranty coverage, cause an internal
buildup of rust and scale and / or shorten engine life.
Prevent dirt and debris from contaminating the engine
coolant. Carefully
surrounding area before you remove the cap.
Never mix different types of engine coolants. This may
adversely affect the properties of the engine coolant.
Never overfill the engine with engine oil.
Always keep the oil level between the upper and lower lines
on the oil cap / dipstick.
For maximum engine life, DOOSAN recommends that when
shutting the engine down, you allow the engine to idle,
without load, for five minutes. This will allow the engine
components that operate at high temperatures, such as the
turbocharger (if equipped) and exhaust system, to cool
slightly before the engine itself is shut down.
Never use an engine starting aid such as ether. Engine
damage will result.
Always be environmentally responsible.
Follow the guidelines of the EPA or other governmental
agencies for the proper disposal of hazardous materials
such as engine oil, diesel fuel and engine coolant. Consult
the local authorities or reclamation facility.
Never dispose of hazardous materials irresponsibly by
dumping them into a sewer, on the ground, or into ground
water or waterways.
Failure to follow these procedures may seriously harm the
environment.
