To prevent electrical shock the following instruction must be followed.
Before the generator can be connected to a building’s electrical
system, a licensed electrician must install an isolation (transfer)
switch in the building’s main fuse box. The switch is the connection
point for generator power and allows selection of generator or main
line power to the building.
This will prevent the generator from charging the main power line
(backfeeding) when the main power supply has failed or has been
turned off for line repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and building electrical
system damage can occur when normal operating power returns if
unit is used without an isolation switch.

CAUTIONS AGAINST BURNS & BATTERY EXPLOSION
ENGLISH
A To avoid burns, be alert for hot components, e.g. muffler,
muffler cover, radiator, pipes, hoses, engine body,
coolant, engine oil, etc. during operation and just after the
engine has been shut off.
A DO NOT remove the radiator cap while the engine is
running or immediately after stopping. Otherwise hot
water from the radiator will escape under pressure
causing injury by scalding. Wait for more than 10 minutes
to allow the coolant to cool down, before removing the
cap.
A Make sure to close the drain valve of coolant and engine
oil, close radiator pressure cap and tighten hose clamps
before operating. If any of these parts are taken off, or left
loose, serious personal injury can result.
A The battery presents an explosive hazard. When the
battery is being activated, hydrogen and oxygen gases
are extremely explosive.
A Keep sparks and open flames away from the battery,
especially when charging the battery. DO NOT strike a
match near the battery.
A DO NOT check battery charge by placing a metal object
across the terminals. Use a voltmeter or hydrometer.
A DO NOT charge battery if frozen, there is a risk of
explosion. When battery is frozen, allow the battery to
warm up to 16 C (61 F) before charging.
A DO NOT use or charge the battery if its fluid level is below
the LOWER (lower limit level) mark (refillable type battery
only).
Otherwise, the component parts may deteriorate earlier
than expected, which may shorten the service life or
cause an explosion. Add distilled water until the fluid level
CONDUCTING SAFETY CHECKS & MAINTENANCE
A Know how to stop the generator quickly, and understand
operation of all the controls. DO NOT permit anyone to
operate the generator without proper instruction.
A When checking engine or servicing, place the generator
in an open area and level ground. DO NOT work on
anything that is supported ONLY by lift jacks or a hoist.
Always use blocks or safety stands to support the
generator before servicing.
A Detach the battery from the generator before conducting
service.
Put a “DO NOT OPERATE!” tag on the key switch and
remove the key to avoid accidental starting.
A To avoid sparks from an accidental short circuit, always
disconnect the battery’s ground cable (-) first and
connect it last.
A Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skins and clothing and cause
blindness if splashed into eyes. Keep electrolyte away
from eyes, hands and clothing.
If you spill electrolyte on yourself, flush with water, and
get medical attention immediately.
A Be sure to stop the engine and remove the key when
conducting daily and periodic maintenance, servicing
and cleaning.
A Check or conduct maintenance after the engine, coolant,
muffler, or muffler cover have cooled off completely.
A Always use the appropriate lifting equipment and make
sure safety stands are in good condition when performing
any service work. Make sure that you understand how to
use the equipment before servicing.
A Use ONLY the correct engine flywheel rotating
techniques for manually rotating the engine. DO NOT
attempt to rotate the engine by pulling or prying on the
cooling fan or V-belt. This practice can cause serious
personal injury or premature machine damage to the
cooling fan.
A Replace fuel, lubricant and coolant hoses with their hose
clamps every 2 years or earlier if required. They are
made of rubber and deteriorate over time whether used
or not.
A When servicing is performed together by two or more
persons, take care to perform all work safely.
A Keep first aid kit and fire extinguisher handy at all times.

APPLICATION RANGE
You can operate the J-series generator in the following
range.
A Connecting a motor.
When connecting to a line starting motor, these
generators may be used to start a submerged pump of
3.7kW, 5.5kW, 7.5kW (three phase). When starting
the motor, the voltage drops immediately. The circuit
may be opened if an electromagnetic switch is
connected to the same circuit. When connecting two
motors or more, make sure the total current capacity
of the motors does not exceed the total rated current.
A Connecting to lights and electric heaters.
When connecting to lights or electric heaters, the
generator can be used up to the rated capacity. When
using a single phase, it can be used up to the rated
current.
A Power factor calculations.
The power factor calculation is used to determine
input of the electrical devices.
Power factors of commonly used devices are listed in the
following table.
ENGLISH
A Keep an inverter load below 50% of the generator
capacity.
A Make sure that total active mercury lamp load is below
30% or so of the generator capacity. Turn on the
mercury lamps one by one. Be careful not to turn off
the lamps and on again immediately. The generator
voltage may rise to extremely high levels and the AVR
may get damaged.
A Before turning on the lamps again, wait for 10 minutes
or so until the lamps cool down enough.
A The data shown above is only a guideline to
approximate load capacities and may vary from
generator model to generator model, with different
types of loads at rated outputs. These values may be
different from actual applications because of the input
characteristics peculiar to each load.
A Ordinarily, a motor is rated in kW. This does not refer
to motor output.
A If a lighting system is employed together with some
types of computers and inverter air-conditioners and/
or the regulated power supply for TV sets, the lights
might suffer flickering. This phenomenon does not
indicate a fault of the generator: it is caused by poor
matching between the above-mentioned regulated
power supply and the generator's automatic voltage
regulator. In such a case, modify the load combination
to eliminate the flickering.

BConnection Notes
To avoid personal injury:
A Before the generator can be
connected to a building’s electrical
system, a licensed electrician must
install an isolation (transfer) switch
in the building’s main fuse box. The
switch is the connection point for
generator power and allows
selection of generator or main line
power to the building. This will
prevent the generator from charging
the main power line (backfeeding)
when the main power supply has
failed or has been turned off for line
repair. Backfeeding can electrocute
or injure line maintenance personnel.
Also, generator and building
electrical system damage can occur
when normal operating power
returns if unit is used without an
isolation switch.

To avoid the possibility of battery
explosion:
The battery comes in two types:
refillable and non-refillable. For using
the refillable type battery, follow the
instructions below.
A DO NOT use or charge the battery if
the fluid level is below the LOWER
(lower limit level) mark.
Otherwise, the battery component
parts may deteriorate prematurely,
shorten the battery's service life;
which may cause an explosion.
Immediately, add distilled water until
the battery's fluid level comes
somewhere between the UPPER and
LOWER levels.
A Keep all sparks and flames away
from the battery and fuel tank. A
battery, especially when charging,
will give off hydrogen and oxygen
gases which can explode and cause
serious personal injury.
To avoid personal injury from contact
with moving parts;
A DO NOT open the door or generator
side cover while the engine is
running.
A Do not touch muffler or exhaust
pipes while they are hot; Severe
burns could result.
BBattery
The battery is shipped in dry, charged condition without
electrolyte.
The battery must be charged properly before using for the
first time.
1. Remove the vent plugs.
2. Fill cells up to the upper level with electrolyte.
[Specific gravity of sulfuric acid 1.270 to 1.290 (at
20 C=68 F)]
3. Allow the battery to sit for about one hour after filling.
4. If the electrolyte level is dropped, refill with electrolyte
up to the upper level.
5. Replace the vent plugs.
6. Charge the battery at the normal charging rate of 6.0
amperes.
7. Wash off any electrolyte which may have spilled.
A The duration of dry charged efficiency, will decrease in
proportion to the period of time elapsed after shipment
and during storage. To obtain the longest service life
of the battery, it is necessary for the battery to be
charged for a sufficient period of time. Continue to
charge until all cells are gassing freely, and the
voltage and specific gravity reading in all cells remain
constant for 3 or more successive readings taken at
30 minute intervals.
A When the battery has been charged fully, the specific
gravity of electrolyte should be 1.270 to 1.290 (at 20 C
=68 F).
BEngine Oil
The generator has been shipped without engine oil.
Fill with oil to the correct level before attempting to
start the engine.
1. Place the machine on a level surface.

A Be sure to use a strainer when filling the fuel tank, or
dirt or sand in the fuel may cause trouble in the fuel
injection pump.
A Always use diesel fuel. You are required not to use
alternative fuel, because its quality is unknown and
affect the generator performance. Kerosene, which is
very low in cetane rating, adversely affects the engine.
Diesel fuel differs in grades depending on the
temperature.
A Be careful not to let the fuel tank become empty, or air
can enter the fuel system, necessitating bleeding
before next engine start.
BAir Bleeding the Fuel System
To avoid personal injury;
A Do not bleed a hot engine as this
could cause fuel to spill onto a hot
exhaust manifold creating a danger
of fire.
Air bleeding of the fuel system is required if;
A after the fuel filter and pipes have been detached and
refitted;
A after the fuel tank has become empty; or
A before the engine is to be used after long storage.

ENGLISH
To avoid personal injury:
A DO NOT stop the engine suddenly,
stop it after about 5 minutes of
unloaded idling.
A Work only after letting the engine and
radiator cool off completely (more
than 30 minutes after it has been
stopped).
A DO NOT remove the radiator cap
while coolant is hot. When cool,
rotate cap slowly to the first stop to
allow excess pressure to escape.
Then remove cap completely.
If overheating should occur, steam
gushes out from the radiator or
reserve tank; Allow the engine to
cool before attempting to open the
cap. Severe burns could result.
2. If the radiator is provided with a reserve tank, check
the coolant level of the reserve tank. When it is
between the "FULL" and "LOW" marks, the coolant
will usually last for one day’s work.
(1) Reserve tank
(2) Cap
3. When the coolant level drops due to evaporation, add
only coolant up to the full level.
4. Check to see the two drain cocks; one is at the
crankcase side and the other is at the lower part of the
