1. GENERATOR/WELDER SAFETY
TO ENSURE SAFE OPERATION -
Place the generator/welder on a firm, level surface; avoid loose sand or
snow. If the generator/welder is tilted or overturned, fuel spillage and a
fire may result.
To prevent fire hazards and to provide adequate ventilation, keep the
generator/welder at least 1 meter (3 feet) away from buildings and
other equipment during operation. Do not place flammable objects
close to the generator/welder.
Children and pets must be kept away from the area of operation due to
a possibility of electric shock or burns from hot components.
Know how to stop the generator/welder quickly, and understand the
operation of all the controls. Never permit anyone to operate the
generator/welder without proper instruction.
The generator/welder is a potential source of electrical shock if misus-
ed. Do not expose the generator/welder to moisture, rain or snow. Do
not let the generator/welder get wet, and do not operate it with wet
hands.
Use adequate eye protection. Eye protection is of the utmost impor-
tance, not only for the operator, but also for any other personnel in the
vicinity while welding is being done. Eye hazards include arc’ glare,
reflected glare, stray flashes, sparks, and flying bits of molten metal.
Looking at a welding arc with unprotected eyes may produce severe
pain and even temporary blindness.
Use a helmet or hand-held shield with a #IO or darker filter lens.
Filter lenses eliminate the harmful effects of infrared and ultraviolet
radiation frop the arc and reduce the glare from the arc light as well.
Wear protective clothing such as leather gloves, cap, sleeves, jacket,
apron, and high-top safety shoes. All outer clothing m&t be free of oil
and grease.

Gasoline is extremely flammable and is explosive under certain
conditioris.
Refuel in a well-ventilated area with the engine stopped. Do not smoke
or allow flames or sparks in the refueling area or where gasoline is
stored.
Do not overfill the fuel tank. After refueling, make sure the ta,nk cap is
closed properly and securely.
Be careful.not to spill fuel when refueling. Fuel vapor or spilled fuel may
ignite. If any fuel is spilled, make sure the area is dry before starting the
engine.
Never run the engine in an enclosed or confined area. Exhaust contains
poisonous carbon monoxide gas; exposure may cause loss of consciousness and may lead to death.
Provide adequate ventilation when welding; welding vapors are harmful
to your health.
The muffler becomes very hot during dperation and remains sufficiently
hot to inflict burns if touched, even after shutting off the engine. To prevent severe burns or fire hazards, let the engine cool before transporting
the generator/welder or storing it indoors.
Connections for standby power to a building’s electrical system must be
made by a qualified electrician and must comply with all applicable laws
and electrical codes. Improper connections can allow electrical current
from the generator to backfeed into the utility lines. Such backfeed may
electrocute utility company workers or others who contact the lines during a power outage, and when utility power is restored, the generator
may explode, burn, or cause fires in the building’s electrical system.
CAUTION: Equipment damage and corrosion from sand, dirt, and water
may occur if the generator is overturned or sinks into’s soft surface.

3. PRE-OPERATION CHECK
Check the generator/welder on a level surface with the engine stopped.
Engine Oil
CAUTION: Engine oil is a major factor affecting engine performance and
service life. Nondetergent oils, castor-based oils, and 2-stroke oils are nor
recommended because they have inadequate lubricating characteristics.
Use Honda 4-stroke oil, or an
equivalent high detergent, premium
quality motor oil certified to meet or
exceed U.S. automobile manufacturers’
Classification SG, SF/CC, CD. Motor
oils classified SG, SF/CC, CD will
show this designation on the container.
SAE low-30 is recommended for
general, all-temperature use. Other
viscosities shown in the chart may
be used when the average temperature in your area is within the in-
dicated range.

Your engine- is designed to use any gasoline that has a pump octane
number (y) of 86
or higher, or that has a research octane number
of 91 or higher. Gasoline pumps at service station normally diSplay the
pump octane number.
We recommend that you use unleaded fuel because‘it produces fewer
engine and spark’plug deposits and extends the life of exhaust system
components.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid
getting dirt, dust or water in the fuel tank. Use of a lower octane gasoline
can cause persistent “pinging” or heavy “spark knock” (a metallic

l
Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.
GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure it’s
octane rating is at least as high as that recommended by Honda. There are
two types of “gasohol”: one containing ethanol, and the other containing
methanol. Do not use gasohol that contains more than 10% ethanol. Do
not use gasoline containing methanol (methyl or wood alcohol) that does
not also contain cosolvents and corrosion inhibitors for methanol. Never
use gasoline containing more than 5% methanol, even if it has cosolvents B
and corrosion inhibitors.
NOTE:
l
Fuel system damage or engine performance problems resulting from the
use of fuels that contain alcohol is not covered under the warranty.
Honda cannot endorse the use of fuels containing methanol since
evidence of their suitability,is as yet incomplete.
l
Before buying fuel from an unfamiliar station, try to find out if the fuel
contains alcohol, if it does, confirm the type and percentage of alcohol
used. If you notice any undesirable operating symptoms ,while using a
gasoline that contains alcohol, or one that you think contains alcohol,
switch to a gasoline that you know does not contain alcohol.

Air Cleaner
Check the air cleaner element to be sure it is clean and in good condition.
Clean or replace the element if necessary (page 31).
CAUTION: Never run the engine without the air cleaner. Rapid engine wear
will result from contaminants, such as dust and dirt, being drawn through
the carburetor, into the engine.
