California Proposition 65
WARNING
Engine exhaust, some of its constituents,
certain vehicle components and fluids,
contain or emit chemicals known to the
State of California to cause cancer and birth
defects or other reproductive harm.
WARNING
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.

ENGLISH
HANDS AND BODY AWAY FROM THE ROTATING PARTS
ADO NOT operate the generator with the side covers removed or
open. Serious personal injury may result if fingers or clothing are
caught in the rotating parts.
ABe sure to stop the engine before checking or adjusting belt tension
and cooling fan.
ATo avoid personal injury, keep your hands and body away from the
rotating parts, such as cooling fan, V-belt, fan drive pulleys or
flywheel.
ADO NOT run the engine with installed safety guards detached. Install
safety guards securely before operation.
ESCAPING FLUID
ARelieve all pressure in the oil and the cooling systems
before any lines, fittings or related items are removed or
disconnected.
ABe alert for possible pressure when disconnecting any
device from a system that utilizes pressure. DO NOT
check for pressure leaks with your hand. High pressure oil
or fuel can cause serious personal injury.
AEscaping fluid under pressure has sufficient force to
penetrate skin causing serious personal injury.
AFluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected leaks:
DO NOT use hands or body. Use safety goggles or other
eye protection when checking for leaks.
AIf injured by escaping fluid, see a medical doctor at once.
This fluid can produce gangrene or severe allergic
reaction.

-5SAFE OPERATION
ENGLISH
CAUTIONS AGAINST BURNS & BATTERY EXPLOSION
ATo 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.
ADO 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.
AMake 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.
AThe battery presents an explosive hazard. When the battery is being
activated, hydrogen and oxygen gases are extremely explosive.
AKeep sparks and open flames away from the battery, especially when
charging the battery. DO NOT strike a match near the battery.
ADO NOT check battery charge by placing a metal object across the
terminals. Use a voltmeter or hydrometer.
ADO NOT charge battery if frozen, there is a risk of explosion. When
battery is frozen, allow the battery to warm up to 16 (61 ) before
charging.
ADO 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 is between the UPPER and
LOWER levels.
ANTI-FREEZE & DISPOSAL OF FLUIDS
ADO NOT run the engine with installed safety guards detached. Anti-
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 or
genuine KUBOTA 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.

SAFE OPERATION-6
ENGLISH
CONDUCTING SAFETY CHECKS & MAINTENANCE
AKnow how to stop the generator quickly, and understand operation of
all the controls. DO NOT permit anyone to operate the generator
without proper instruction.
AWhen 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.
ADetach 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.
ATo avoid sparks from an accidental short circuit, always disconnect
the battery's ground cable first and connect it last.
ASulfuric 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.
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 cooled off completely.
AAlways 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.
AUse 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.
AReplace 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.
AWhen servicing is performed together by two or more persons, take
