1. Safety Precautions
The electric power generated by the diesel engine of the generator can be used for many
kinds of electric appliances. When handling it, please keep to the following matters. Please
make sure you review each precaution carefully.
EXHAUST PRECAUTIONS
•Never inhale exhaust gasses. They contain
carbon monoxide, a colorless, odorless and
extremely dangerous gas which can cause
unconsciousness or death.
•Never operate the generator indoor or in a
poorly ventilated area, such as tunnel, cave,
etc. Exercise extreme care when operating
the generator near people or animals. Keep
the exhaust pipe free of foreign objects.
REFUELING PRECAUTIONS
•Do not refuel indoors or in a poorly
ventilated area. Be sure to stop the
generator prior to refueling. Do not overfill
the tank. If fuel is spilt, wipe it away carefully
before starting the engine.
WHEN CHARGING THE BATTERY
•Battery electrolyte contains sulfuric acid. Be
careful of your eyes, skin and clothing. Flush
thoroughly with water and get prompt
medical attention in case of contacts,
especially if your eyes are affected.
•Charge the battery in a fully ventilated place.
•Be sure to confirm battery polarity.
OTHER SAFETY PRECAUTIONS
•Be careful of hot parts.
The muffler and other engine parts
become very hot while the engine is
running or just after it has stopped.
Operate the engine in a safe area and
keep children away from the running
engine.
•
Where to use the generator
Do not use it near flammables. Use it
more than 1 meter away from buildings
or any other facilities.
• When using the generator
Do not tip or move.
Do not cover it with a box or fence it
around.
Never unscrew the dipstick when using
the generator set, or else scald will be
caused by ejective oil. Do not touch
the
generator in the rain. And, do not
splash wat.er or touch with wet hand.
•
To avoid an electric shock, ground
the
generator from the ground terminal.
•
Avoid using generator at the place
where the ground is not firm.
• Never connect generator to the wiring
of
a power company.

2. Name of Parts
3. Before Starting
Before starting the engine. check the generator set on the place where it is flat by placing it horizontally.
3-1 Checking and selecting engine oil
•The engine may be damaged if operated with
insufficient lube oil. It is also dangerous to
supply too much lube oil to the engine because
a sudden increase in engine rpm could be
caused by its combustion. Always check the
lube oil level before starting the engine and
refill if necessary.
•Make sure to check oil level and to refill with
oil to the specified level before starting the
generator even though it is equipped with a
low oil pressure warning system.
Use proper lube oil to preserve your engine
ENGINE OIL
We recommend A.P.I engine service classification
of CC or CD. Always use the oil with the right
viscosity for the ambient temperature in which your
engine is being operated. Use the chart right side
for choosing your engine oil.
Lube oil capacity (L) 1.7
Upper Level (H)
Lower Level (H)
4
Oil filter cap /
Dipstick

•When checking the oil level, make sure
your engine is sitting level. If it is tilted,
you may add either too much or too
little oil. If you overfill, your engine will
consume too much oil and the oil
temperature will become dangerously
high if you do not add enough oil,
your engine could seize up.
•When checking the oil, simply dip the
dipstick into the oil pan. Do not screw
in the dipstick.
•Be sure to check the engine on a level
surface with the engine stopped.
•Keep the oil screw plug in the bonnet
except adding oil. If the plug is not in
place, rain, dirt, and other
contaminants may enter the engine
and cause accelerated wear out
(abrasion) of internal parts. This can
cause serious problems.
3-2 Selection and handling of fuel oil
Only use diesel light oil.
When filling the fuel tank from drums, make
sure that no dust or water are mixed in the fuel.
This may lead to serious fuel-injection pump
and nozzle problems.
•Only use the recommended diesel fuel
oil. Use of non-recommended fuel may
cause the engine damage.
•Fuel should have a cetane value of
more than 45 in order to prevent
difficult starting, misfiring, and white
exhaust smoke.
•Diesel fuel oil substitutes are not
recommended; they may be harmful to
the fuel system components.
•Fuel should be free of water or dust
because these cause trouble in the fuel
injection pump and nozzle.
After purchasing fuel: Allow drum to
stand 3-4 days.
After 3-4 days: Put a suction pipe
halfway into the drum. (Water and dust
accumulate in the lower position of the
drum.)
•Refuel in a well-ventilated area with the
engine stopped.
•Do not smoke or allow flames or sparks
in the area where the engine is refueled
or where gasoline is stored.
•Do not overfill the tank and make sure
the filter cap is securely closed after
refueling.
•Be careful not to spill fuel when
refueling if any fuel is spilled, make
sure the area is dry before starting the
engine.
Overfill is dangerous. Do not fill the tank
beyond the top of the red plug inside the fuel
tank filter.
3-3 Connecting the battery
(1) Unscrew / Remove the battery bracket
(2) Remove the battery terminal cover

(3) Connect the wires to the battery terminals.
Respect the connection order (BLACK first, then
RED second)
(4) Secure the battery bracket
4. Starting
4-1 Electric starting
(1) Starting
a. Set the fuel cock (A) at the "O" (Open)
position.
A. Open the fuel cock
b. Set the engine speed lever (B)
to "RUN" position.
c. Turn the starting key clockwise to
"START" position.
d. Remove your hand from the key as
soon as the engine starts.
e. If the engine does not start after 10
seconds, wait a while (for about 15
seconds) before attempting to start
again.
•If the starting motor is working for too
long, the battery will go flat and motor
seize up will occur. Always leave the
starting key turned on, at the "ON"
position, while the engine is running.
(2) Battery
Check the level of the fluid in the battery every
month. When the level has dropped to the
lower mark replenish with distilled water up to
the upper mark.
•If the battery fluid is short, the engine may
not start because too little electricity is
reaching the starter motor. Always keep
the fluid level between the upper and
lower limits.
•If too much battery fluid is supplied, the
fluid may spill and corrode the
surrounding parts.
4-2 Electric starting using
decompression (weak battery)
If the battery is weak, discharged, or old, it may
not be able to generate enough power to start
the engine (Replace the battery and repeat
4-1 Electric starting)
It is also possible to decompress the engine
before starting, which would require less power
to start the engine and could enable an electric
start of the unit with a weak battery.
Decompression process as follows:
(1) Unscrew and remove the top cover
(See below pic)

else, severe damage will occur.
5. Operating Your
Generator Set
5-1 Operating your generator
(1) Warm up the engine without load for 3
minutes.
(2) This generator is equipped with low
oil warning system. The engine will stop
automatically in case of low oil pressure or
a lubrication oil shortage. The engine will
stop immediately without a lubrication oil
refill. Check the oil level and refill.
(3) Do not loosen or readjust either the engine
speed limiting bolt or fuel injection limiting
bolt [They had been already well adjusted
before leaving factory), otherwise
performance may be affected.
5-2 Checks during operation
(1) Any abnormal sound or vibration?
(2) The engine misfiring or running rough?
(3) What about the color of the exhaust gas?
(Is it black or too white?). If you notice any
situation mentioned above, please contact
your dealer.
5-3 Load
To add load according to specified parameter.
A.C application
(1) Set AC breaker to "ON". Pilot lamp will
illuminate, the speed of generator must
reach rated speed [lever at top).
(2) Insert the receptacle with the plugs of
electric instruments to be connected, keep
the switches of the connected electric
instruments to "OFF'.
•The instruments which require much
starting current and some kinds of motors
may be unable to be use even if they are
within the applicable scope.
•The circuit breaker turns "OFF' when the
current exceeding the applicable scope is
used or when the applied instrument is
defective.
•The current of the instruments which
should not exceed the rated current
showed on the socket, or else it may
damage the machine.
DC application
(1) When the instruments connect with the DC
terminal, please make sure to the positive
polarity.
(2) DC output 12V 8.3A - 100W. 10
6. Stopping Your
Generator Set
(1) Pull out the plug of an electric appliance
from the receptacle
(2) Set the AC breaker to "OFF'
(3) From lowest to highest load, run the engine
for about 3 minutes with no load.
(4) Return the engine speed lever to the
"STOP" position
(5) In electric-start models, return the starter
key to the "OFF" position
(6) Set the fuel chock lever to "S" (closed)
position.
Slowly pull out the recoil handle until pressure
is felt (that is, to the point in the compression
stroke where the intake and exhaust valves are
closed), and leave the handle in this position
this prevents rust from forming while the
engine is not in use.
When stopping the engine, reduce the load slowly.
Do not stop the engine suddenly since it may cause
the temperature to rise abnormally.
