ENGLISH

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.

SAFETY PRECAUTIONS

A To operate the machine safely, be sure to follow the instructions below.

DANGER

To avoid personal injury:
A Hazard of being caught up in the machine: Do

not touch any rotating parts.

A Do 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:
A Exhaust gas poisoning hazard: Do not use the

machine in any poorly-ventilated place such as
indoors and tunnels.

A Exhaust gas poisoning and fire hazard: Do not

direct the exhaust to people and buildings.

A Electric shock hazard: Do not touch the machine

with wet hands.

A Electric shock hazard: Do not touch the

terminals and sockets while the machine is
running.

A Electric shock and injury hazard: Do not check

and service the machine while it is running.

A Electric shock and injury hazard: Do not tamper

with the machine.

A Fire hazard: Flames prohibited. Keep the

machine more than 1 m(3 feet) away from
flammable materials.

A Electric shock hazard: Do not use the machine in

the rain.

2 SAFETY PRECAUTIONS

ENGLISH

CAUTION

To avoid personal injury:
A Electric shock and fire hazard: Do not connect

the machine to any indoor (commercial) power
outlet.

A Electric shock and injury hazard: Do not allow

children to run the machine.

A Electric shock and injury hazard: Turn off the

circuit breaker before starting the machine.

A Injury hazard: Do not touch the muffler.
A Injury hazard: Do not run the machine tilted.
A Injury hazard: Do not move the machine while it

is running.

A Fire hazard: Stop the engine before adding fuel.
A Fire hazard: Do not enclose the machine, nor

cover it with a box or the like.

A Fire hazard: Pay attention to the type and

amount of fuel.

A Do not get the warning label dirty or peeled off.
A Be sure to hand over the operation manual to

any other operator.

A Electric shock hazard: Ground the machine

using the ground terminal on the control panel.

3SAFETY PRECAUTIONS

ENGLISH

CAUTION

To avoid personal injury:
A Anti-freeze contains poison. Wear rubber gloves

to avoid personal injury. In case of contact with
skin, wash it off immediately.

A DO NOT mix different types of Anti-freeze. The

mixture can produce chemical reaction causing
harmful substances. Use approved Anti-freeze.

A Be 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.

A When draining fluids from the engine, place

some container underneath the engine body.

A DO NOT pour waste onto the grounds, down a

drain, or into any water source.

4 SAFETY PRECAUTIONS

ENGLISH

CAUTION

To avoid personal injury:
A When 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.

A Detach the battery from the engine before

conducting service. Put a "DO NOT OPERATE!"
tag in the key switch 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 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 been
cooled off completely.

A Always 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.

A Use 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.

A Replace 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.

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.
