SAFETY PRECAUTIONS
ATo operate the machine safely, be sure to follow the instructions below.
DANGER
To avoid personal injury:
AHazard of being caught up in the machine: Do
not touch any rotating parts.
ADo not use or charge the battery if its fluid level
stands below the LOWER mark.
Otherwise, the component parts may deteriorate
earlier than expected, which may shorten the
service life or cause an explosion. Immediately,
add distilled water until the fluid level is between
the UPPER and LOWER levels. (for only refillable
battery)
WARNING
To avoid personal injury:
AExhaust gas poisoning hazard: Do not use the
machine in any poorly-ventilated place such as
indoors and tunnels.
AExhaust gas poisoning and fire hazard: Do not
direct the exhaust to people and buildings.
AElectric shock hazard: Do not touch the machine
with wet hands.
AElectric shock hazard: Do not touch the
terminals and sockets while the machine is
running.
AElectric shock and injury hazard: Do not check
and service the machine while it is running.
AElectric shock and injury hazard: Do not tamper
with the machine.
AFire hazard: Flames prohibited. Keep the
machine more than 1 m(3 feet) away from
flammable materials.
AElectric shock hazard: Do not use the machine in
the rain.
2 SAFETY PRECAUTIONS
ENGLISH
CAUTION
To avoid personal injury:
AElectric shock and fire hazard: Do not connect
the machine to any indoor (commercial) power
outlet.
AElectric shock and injury hazard: Do not allow
children to run the machine.
AElectric shock and injury hazard: Turn off the
circuit breaker before starting the machine.
AInjury hazard: Do not touch the muffler.
AInjury hazard: Do not run the machine tilted.
AInjury hazard: Do not move the machine while it
is running.
AFire hazard: Stop the engine before adding fuel.
AFire hazard: Do not enclose the machine, nor
cover it with a box or the like.
AFire hazard: Pay attention to the type and
amount of fuel.
ADo not get the warning label dirty or peeled off.
ABe sure to hand over the operation manual to
any other operator.
AElectric shock hazard: Ground the machine
using the ground terminal on the control panel.
3SAFETY PRECAUTIONS
ENGLISH
CAUTION
To avoid personal injury:
AAnti-freeze contains poison. Wear rubber gloves
to avoid personal injury. In case of contact with
skin, wash it off immediately.
ADO NOT mix different types of Anti-freeze. The
mixture can produce chemical reaction causing
harmful substances. Use approved Anti-freeze.
ABe mindful of the environment and the ecology.
Before draining any fluids, find out the correct
way of disposing of them. Observe the relevant
environmental protection regulations when
disposing of oil, fuel, coolant, brake fluid, filters
and batteries.
AWhen draining fluids from the engine, place
some container underneath the engine body.
ADO NOT pour waste onto the grounds, down a
drain, or into any water source.
4 SAFETY PRECAUTIONS
ENGLISH
CAUTION
To avoid personal injury:
AWhen checking engine or servicing, place the
engine on a wide and level ground. DO NOT work
on anything that is supported ONLY by lift jacks
or a hoist. Always use blocks or correct stands
to support the engine before servicing.
ADetach the battery from the engine before
conducting service. Put a "DO NOT OPERATE!"
tag in the key switch to avoid accidental starting.
ATo avoid sparks from an accidental short circuit
always disconnect the battery's ground cable (-)
first and connect it last.
ABe sure to stop the engine and remove the key
when conducting daily and periodic
maintenance, servicing and cleaning.
ACheck or conduct maintenance after the engine,
coolant, muffler, or muffler cover have been
cooled off completely.
AAlways use the appropriate tools and jig-fixture
in good condition when performing any service
work. Make sure you understand how to use
them before service.
AUse ONLY correct engine barring techniques for
manually rotating the engine. DO NOT attempt to
rotate the engine by pulling or prying on the
cooling fan and V-belt. This practice can cause
serious personal injury or premature machine
damage to the cooling fan.
AReplace fuel pipes and lubricant pipes with their
hose clamps every 2 years or earlier whether
they are damaged or not. They are made of
rubber and are aged gradually.
AWhen servicing is performed together by two or
more persons, take care to perform all work
safely.
AKeep first aid kit and fire extinguisher handy at
all times.

SERVICING OF GENERATOR
Your dealer is interested in your new generator and has
the desire to help you get the most value from it. After
reading this manual thoroughly, you will find that you
can do some of the regular maintenance yourself.
However, when in need of parts or major service, be
sure to see your KUBOTA Dealer.
For service, contact the KUBOTA Dealership from
which you purchased your generator or your local
KUBOTA Dealer.
When in need of parts, be prepared to give your dealer
the generator and engine serial numbers.
Locate the serial numbers now and record them in the
space provided below.

8 GROUND FAULT CIRCUIT INTERRUPTER (GFCI) RECEPTACLE
ENGLISH
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) RECEPTACLE
WARNING
(1)Do not operate in wet or damp
conditions.
(2)This Ground Fault Circuit
Interrupter reduces the hazards
of ground fault currents that can
cause loss of life.
(3)The GFCI will not protect against
short circuits or over loads.
(4)Do not use the GFCI or other
standard receptacles on the
circuit until the GFCI has been
fully and successfully tested.
See following test procedure.
TESTING PROCEDURE
(1) Unplug all appliances from the GFCI receptacle.
(2) Start the engine.
(3) At the circuit breaker turn power ON to the circuit.
(4) Depress the "TEST" button.
The "RESET" button should extend with a click.
If the "RESET" button does not extend, contact your
KUBOTA dealer.
(5) Depress the "RESET" button firmly into the GFCI
unit, until an audible click is heard.
If it resets properly, the "RESET" button will be flush
with the surface of the "TEST" button.
If the "RESET" button is not flush with "TEST"
button, contact your KUBOTA dealer.
BWhen the "RESET" button extends during
operation:
(1) Unplug all appliances from the GFCI receptacle.
(2) Depress the "RESET" button firmly into the GFCI
unit, until an audible click is heard.
If the GFCI can not be reset, the GFCI is faulty.
Contact your KUBOTA dealer. If the GFCI resets
properly, check such things as fault insulation or wet
wiring inside the appliance or its cord. If you've
found the short, it should be repaired before it is
used again.
1. Perform this test on a regular monthly basis to
ensure proper operation of the GFCI receptacle.
2. If the generator is stored outdoors, unprotected from
the weather, test the GFCI receptacle before each
use.
3. An attached "OCCUPANT'S TEST RECORD" label
should be retained and placed in a conspicuous
location to remind the operator that for maximum
protection against electrical shock.
4. Record your test on the GFCI test card.
5. After disassembling and assembling the generator,
check the circuit of GFCI with the RECEPTACLE
CIRCUIT TESTER and test as above TEST
PROCEDURE.
BEasy Checker
When an abnormal condition occurs with a part
monitored by the easy checker while the engine is
running, a lamp flashes to warn the operator of the
impending trouble.
(1) "TEST" button
(2) "RESET" button
(1) Charge warning lamp
(2) Water temperature-overheat warning lamp, flashes on when
cooling water rises to 112° to 118°C.
(3) Engine oil pressure drop warning lamp, flashes on below 68.7
to 127.5 kPa (0.7 to 1.3 kgf/cm2) oil pressure.
(4) Glow timer lamp
