If

fuel is spilt, wipe it off and let dry before starting the engine.

Do

not place inflammables near the generator.
Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or
any other inflammables near the generator.

not operate the generator inside a room, cave, tunnel, or other insuffi-

ciently ventilated area. Always operate it in a well-ventilated area, otherwise

the engine may become overheated, and the poisonous carbon monoxide gas
contained in the exhaust gases will endanger human lives. Keep the gener­ator at least

If

the generator must be used indoors, the area must be well-ventilated and

extreme caution must be taken regarding the discharge of exhaust gases.

Do not enclose the generator nor cover it with a box.

The generator has a built-in forced air cooling system, and may become

overheated if
the weather during non use, be sure to remove it and keep it well away from
the area during generator use.

Operate the generator on a level surface.

It

is not necessary to prepare a special foundation for the generator. However,
the generator will vibrate on an irregular surface,
without surface irregularities.

If the generator is tilted or moved during operation, fuel may spill and/or the

generator may tip over, causing a hazardous situation.

Proper lubrication cannot be expected if the generator is operated on
incline or slope. In such a case, piston seizure may occur even if the oil is
above the upper level.

GROUNDING THE GENERATOR

To

ground the generator to the earth,

connect the grounding lug of the gener-

ator to the grounding spike driven into

the earth or to the conductor which has

been already grounded to the earth.

If such grounding conductor or grounding

electorode is unavailable, connect the

NOTE

:

The National Electrical Code (NEC) requires that all separately derived AC

systems be grounded per Article 250-26. Manufacturer has added a grounding

lug type terminal per Article 250-26 (a) from the noncurrent-carrying metal parts
to the conductor to be grounded. Manufacturer does not supply the required
grounding conductor or grounding electrode because it would be impossible to
cover every exception and all local code requirements. See your local dodes
and the NEC manual for the proper grounding for your application.

WAlTAGE

INFORMATION

Some appliances need a "surge" of energy when starting. This means that the
amount

needed

of

electrical power needed to start the appliance may exceed the amount

to

maintain

its

use.

See the chart on page

15

for

appliances you

may

use

with this generator.

Electrical appliances and tools normally come with a label indicating voltage,
cycles/Hz, amperage (amps) and electrical power needed to run the appliance or

tool. Check with your nearest dealer or service center with questions regarding

power surge of certain appliances or power

tools.

Electrical loads such

as

incandescent lamps and hot plates require the same

wattage to start as is needed to maintain use.

Loads such as fluorescent and mercury lamps require 1.2 to 2 times the

indicated wattage during start-up.

Electrical motors require a large starting current. Power requirements depend
on the type of motor and its use. Once enough "surge"

VOLTAGE DROP

When a long electric extension cord is used to connect an appliance or tool to the

generator, a certain amount of voltage drop or

which recuces the effective voltage available for the appliance or tool. The use of

improper size or gauge of extension cords may cause unsafe or inefficient
operation of your tool or appliance. it may also damage the tool or appliance.

Be

sure that any extension cord that you use is rated to allow sufficient current
flow to the motor or appliance. Select the required wire gauge size according to
the chart below.

MAINTENANCE SCHEDULE

DAILY

Before running the generator, check the following service items:

INSPECTION

PERIODIC MAINTENANCE

Periodic maintenance is vital to safe and efficient operation of your generator.

Check the table below for periodic maintenance intervals.

It is also necessary for the user of this generator to conduct the maintenance and
adjustments on the emission-related parts listed below
control system effective.

to keep the emission

The emission control system consists of the following parts

(1)

Carburetor and internal parts

(4)

Air cleaner elements

(7)

Magneto

The maintenance schedule indicated in the table is based on the normal gener­ator operation. Should the generator be operated in extremely dusty condition or
in heavier loading condition, the maintenance intervals must be shortened de­pending on the contamination of oil, clogging of filter elements, wear of parts, and

PREPARATION FOR STORAGE

The following procedures should be followed prior to storage of your generator for

of

6

periods

Drain fuel from fuel tank carefully by disconnecting the fuel line. Gasoline left
in the fuel tank will eventually deteriorate making engine-starting difficult.

Remove the carburetor float chamber and also drain the carburetor.
Change engine oil.
Check for loose bolts and screws, tighten them if necessary.
Clean generator thoroughly with oiled cloth. Spray with preservative if avail­able.
NEVER USE WATER
Pull starter handle until resistance is felt, leaving handle in that position.
Store generator in a well ventilated, low humidity area.
