General Precautions
1. To use the engine safely and with optimal performance over
long periods of time, engine operators must familiarize them-
selves with the contents of this Operation and Maintenance
Manual and perform both daily and routine inspections.
2. We have divided the contents of this manual into causes
of bodily injury, property damage, and causes of pollu-
tion. Make sure to comply with all instructions concerning
the specified regulations and mounting locations.
Cautions for Starting the Engine
1. Before starting the engine, make sure to read this Opera-
tion and Maintenance Manual carefully and familiarize
yourself with the 'Danger.' 'Warning' and 'Caution' items.
Please contact Hyundai Doosan Infracore if there is any
uncertainty regarding the contents of this manual or if you
have any questions.
2. For the sake of safety, attach a warning to the engine
prohibiting anyone but workers from approaching the
engine while it is in operation. Make sure to notify the
engine operators that the safety of the engine room is
their responsibility.
3. Only authorized personnel may start and operate the
engine. Never allow an unauthorized person to handle
the engine.
4. Do not approach rotating or moving parts while the
engine is in operation.
5. Be careful not to touch or come in contact with the engine
while it is running since it becomes hot during operation.
6. Exhaust gas is poisonous. Before starting the engine,
ventilate the workspace sufficiently; when working in an
enclosed space, check to ensure that the space is venti-
lated.
Cautions for Inspections and Maintenance
1. Make sure to perform inspections and service work only
with the engine stopped. If it is absolutely necessary to
perform inspections or service work with the engine
running, be careful of any possible accidents and
scalding.
2. If performing inspections or service work while the engine
is running cannot be avoided, do not get too close to any
rotating parts.
3. When draining engine oil, make sure to prepare a container
of sufficient size to ensure that engine oil does not overflow.
4. When replacing or refilling engine coolant, open the
coolant cap after cooling the engine sufficiently.
5. Fuel is highly flammable. Smoking or using an open
flame near the engine may cause a fire.
6. Label and store coolant containers separately to avoid
confusion with beverage containers. If coolant is
ingested, seek medical assistance immediately.
7. Follow the instructions provided by the battery manufac-
turer when checking or handling batteries.
While starting the engine or during inspections and
maintenance, if skin accidentally comes in contact with
corrosive acid or fuel, you are burnt by hot oil, or fuel or
antifreeze gets in your eyes, seek medical assistance
immediately.
Severe injuries may occur if gloves or accessories such
as necklaces, rings or watches are caught in rotating
parts during service work while the engine is running.
Do not replace or disconnect any pipes or hoses (engine
fuel circuit, engine oil circuit, coolant circuit and
compressed air circuit, etc.) while the engine is running.
Spurting fluid may cause physical injuries.
If the coolant cap is opened while the engine is still hot,
hot coolant will spurt out and may cause burns. Open the
coolant cap only after cooling the engine sufficiently.
When fuel needs to be refilled, make sure to add fuel
while the engine is stopped.
Battery fluid is toxic, corrosive and explosive. Hence, it
should be handled by trained technicians.
