1. Safety Regulations & Engine Specifications
1.1. General Notes
Day-to-day use of power engines and the service products necessary for running them presents no prob-
lems if the persons occupied with their operation, maintenance and care are given suitable training and
think as they work.
This summary is a compilation of the most important regulations, These are broken down into main sec-
tions which contain the information necessary for preventing injury to persons, damage to property and
pollution. In addition to these regulations those dictated by the type of engine and its site are to be
observed also.
IMPORTANT:
If despite all precautions, an accident occurs, in particular through contact with caustic acids,
fuel penetrating the skin, scalding from oil, antifreeze being splashed in the eyes etc, consult
a doctor immediately.
1.2. Handle Compressed Natural Gas Safety
Natural gas is highly flammable and explosive and may be extremely cold. The following cautions must
be taken to avoid personal injury or engine damage.
●Do not smoke when installing or servicing
the engine or fuel system.
●Installation or servicing of natural gas
equipment must only be conducted in well
ventilated, natural gas compatible areas.
Do not install or service equipment in an
enclosed area where ignition sources are
present without ensuring that an unde-
tected gas leak may be safely vented with-
out being ignited.
●Do not vent natural gas or permit leaks
inside an enclosed area.
Bleed natural gas lines before installing or
servicing any component connected to the
fuel lines.

1.2.1. Avoid heating near pressurized fluid lines
●Wear welding goggles and gloves when
welding or using an acetylene torch.
●Insure a that metal shield separated the
acetylene and oxygen which must be
chained to a cart.
●Do not weld or heat areas near fuel tanks
or fuel lines.
1.2.2. Venting an operable engine to relieve natural gas pressure
●To avoid personal injury an operable nat-
ural gas engine must be kept in a well
ventilated area away from open flames
and sparks.
●If the engine can run, use the following
venting procedure to relive the natural
gas pressure downstream of the shutoff
valve.
1) Shut off manual valves on natural gas
supply lines and main shutoff valve on
natural gas fuel supply line.
2) Start engine and run until it stalls due to
fuel starvation.
3) Check to make sure gauge pressure at point on the natural gas fuel line to be vented has been
reduced to zero. If not, repeat step 1) Then repeat step 2).
4) Disconnect vehicle batteries using switch in battery compartment or by disconnecting battery ground
cable.
5) Slightly loosen the NG fuel line fitting to be serviced in a well ventilated area to allow any remaining
gas to vent.
6) Completely open the fitting that was slightly opened and allow to vent in a well ventilated area.

Safety Regulations & Engine Specifications- 3 -
1.2.3. During commissioning, starting and operation
●This is the safety alert symbol. When you see this symbol in this manual, be alert to the potential for
personal injury.
●Carefully read all safety message in this manual and on your safety signs. Be sure new equipment
components and repair parts include the current safety signs.
●Avoid possible injury or death from runaway. Do not start engine by shorting across starter termi-
nals.
●Prevent fires by keeping machine clean of accumulated trash, grease, fuel and debris.
●When the engine is running, do not get too close to the rotating parts.
●Do not touch the engine with bare hands when it is warm from operation risk of bums.
●Exhaust gases are toxic. If it is necessary to run an engine in an enclosed area, remove the exhaust
gases from the area with an exhaust pipe extension. If you do not have an exhaust pipe extension,
open the doors and get outside air into the area.
●Keep vicinity of engine free of oil and grease. Accidents caused by slipping can have serious conse-
quences.
1.2.4. During maintenance and care
●Always carry out maintenance work when the engine is switched off. If the engine has to be main-
tained while it is running, e.g. changing the elements of change-over filters, remember that there is a
risk of scalding. Do not get too close to rotating parts.
●Change the oil when the engine is warm from operation.
Caution:
There is a rise of burns and scalding. Do not touch oil drain plug or oil filters with bare hands.
●Take into account the amount of oil in the sump. Use a vessel of sufficient size to ensure that the oil
will not overflow.
●Open the coolant circuit only when the engine has cooled down. If opening while the engine is still
warm is unavoidable, comply with the instructions in the chapter "Maintenance and Care".
●Neither tighten up nor open pipes and hoses (lube oil circuit, coolant circuit and any additional
hydraulic oil circuit) during the operation. The fluids which flow out can cause injury.
●Fuel is inflammable. Do not smoke or use naked lights in its vicinity. The tank must be filled only
when the engine is switched off.
●When using compressed air, e.g. for cleaning the radiator, wear goggles.
●Keep service products (anti-freeze) only in containers which can not be confused with drinks con-
tainers.
●Comply with the manufacturer's instructions when handling batteries.
Caution:
Accumulator acid is toxic and caustic. Battery gases are explosive.

Safety Regulations & Engine Specifications - 4 -
1.2.5. When carrying out checking, setting and repair work
●Checking, setting and repair work must be carried out by authorized personnel only.
●Use only tools which are in satisfactory condition. Worn open-end wrench slip, which could lead to
Injury.
●When the engine is hanging on a crane, no-one must be allowed to stand or pass under it. Keep lift-
ing gear in good condition.
●When working on parts which contain asbestos, comply with the notes.
●When checking spark plug do not put your hands under the electric.
●When working on the electrical system disconnect the battery earth cable first. Connect it up again
last in prevent short circuits.
1.2.6. To prevent damage to engine and premature wear
(1) If faults occur, find the cause immediately and have it eliminated in order to prevent more seri-
ous of damage.
(2) Use only genuine DOOSAN spare parts. DOOSAN will accept no responsibility for damage resulting
from the installation of other parts which are supposedly "just as good".
(3) In addition to the above, note the following points.
●Never let the engine run when dry, i.e. without lube oil or coolant.
●Use only DOOSAN-approved service products (engine oil, anti-freeze and anticorrosion agent).
●Have the engine maintained at the specified intervals.
●Do not switch off the engine immediately when it is hot, but let it run without load for about 5 min-
utes so that temperature equalization can take place.
●Never put cold coolant into an overheated engine. See "Maintenance and care".
●Do not add so much engine oil that the oil level rises above the max. marking on the dipstick. Do
not exceed the maximum permissible tilt of the engine. Serious damage to the engine may result
if these instructions are not adhered to.
●Always ensure that the testing and monitoring equipment (for battery charge, oil pressure, cool-
ant temperature) function satisfactorily.
●Do not let the raw water pump run dry, If there is a risk of frost, drain the pump when the engine
is switched off.
(4) Keep no-load operation to a minimum. During no-load operation combustion chamber temperatures
drop to the point where fuel does not burn completely, causing slobbering and white smoke. Always
have some load connected when the gen set is run for long periods.

Safety Regulations & Engine Specifications- 5 -
1.2.7. To prevent pollution
(1) Engine oil, filter elements, fuel filters
●Take old oil only to an oil collection point.
●Take strict precautions to ensure that oil does not get into the drains or into the ground. The
drinking water supply could be contaminated.
●Filter elements are classed as dangerous waste and must be treated as such.
(2) Coolant
●Treat undiluted anti-corrosion agent and / or antifreeze as dangerous waste.
●When disposing of spent coolant comply with the regulations of the relevant local authorities.
(3) Cold Start
●The preheat lamp turns on when the key switch is set to "ON." W h e n the preheat lamp goes off,
proceed as follows. The pre-heater device activates when the coolant temperature is below 25°C,
and the preheating system is automatically adjusted based on the coolant temperature. (The
max. preheating time is around 25 seconds) It does not activate when the coolant temperature is
over 25°C.
Caution:
The engine is equipped with a preheating system for enhancing cold start ability.
●In order to start the engine after the preheat lamp turns off, turn the key switch to the ignition posi-
tion. When the key switch is turned to the ignition position, the pre-heater plug or air heater runs
continuously to make starting the engine easier and reduce white exhaust gas. If the coolant tem-
perature is over 25°C, it is not necessary to operate the pre-heater plug or air heater.
●When the engine starts, set the key switch in the ON position. The timer runs for another 5 min-
utes even after the engine starts to heat the intake air and quickly eliminate white exhaust gas.
Caution:
Do not run the start motor for over 10 seconds. If the engine still cannot be started after
preheating, wait for 30 seconds and then perform preheating again before the second attempt
to start the engine.
1.2.8. Notes on safety in handling used engine oil
Prolonged or repeated contact between the skin and any kind of engine oil decreases the skin.
Drying, irritation or inflammation of the skin may therefore occur. Used engine oil also contains danger-
ous substances which have caused skin cancer in animal experiments. If the basic rules of hygiene and
health and safety at work are observed, health risks are not to the expected as a result of handling used
engine oil
Health precautions:
●Avoid prolonged or repeated skin contact with used engine oil.
●Protect your skin by means of suitable agents (creams etc.) or wear protective gloves.
●Clean skin which has been in contact with engine oil.

Safety Regulations & Engine Specifications - 6 -
- Wash thoroughly with soap and water, A nailbrush is an effective aid.
- Certain products make it easier to clean your hands.
- Do not use petrol, Diesel fuel, gas oil, thinners or solvents as washing agents.
●After washing apply a fatty skin cream to the skin.
●Change oil-soaked clothing and shoes.
●Do not put oily rags into your pockets.
Ensure that used engine oil is disposed of properly.
- Engine oil can endanger the water supply -
For this reason do not let engine oil get into the ground, waterways, the drains or the sewers. Viola-
tions are punishable.
Collect and dispose of used engine oil carefully. For information on collection points please contact
the seller, the supplier or the local authorities.
1.2.9. General repair instructions
1. Before performing service operation, disconnect the grounding cable from the battery for reducing
the chance of cable damage and burning due to short-circuiting.
2. Use covers for preventing the components from damage or pollution.
3. Engine oil and anti-freeze solution must be handled with reasonable care as they cause paint dam-
age.
4. The use of proper tools and special tools where specified is important to efficient and reliable service
operation.
5. Use genuine DOOSAN's parts necessarily.
6. Used cotter pins, gaskets, O-rings, oil seals, lock washer and self-lock nuts should be discarded and
new ones should be prepared for installation as normal function of the parts can not be maintained if
these parts are reused.
7. To facilitate proper and smooth reassemble operation, keep disassembled parts neatly in groups.
Keeping fixing bolts and nut separate is very important as they vary in hardness and design depend-
ing on position of installation.
8. Clean the parts before inspection or reassembly. Also clean oil ports, etc. using compressed air to
make certain they are free from restrictions.
9. Lubricate rotating and sliding faces of parts with oil or grease before installation.
10. When necessary, use a sealer on gaskets to prevent leakage.
11. Carefully observe all specifications for bolts and nuts torques.
12. When service operation is completed, make a final check to be sure service has been done property.
