●The following statement refers to the noise level data contained in the EC Declaration of
conformity contained on the next page of this manual.
“The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is
a correlation between the emission and exposure levels, this cannot be used reliably to determine
whether or not further precautions are required. Factors that influence the actual level of exposure
of work-force include the characteristics of the work place, the other sources of noise, etc. i.e. the
number of machines and other adjacent processes, and the length of time for which an operator is
exposed to the noise. This information, however, will enable the user of the machine to make a
better evaluation of the hazard and risk”.

1. Safety Precautions
Warning: Suffocation from Exhaust Fume
Do not operate the equipment in a poorly-ventilated area such as indoors or within a
tunnel because the engine exhaust fume includes components that are harmful to
humans.
Warning: Suffocation from Welding Fume
Always be sure to wear a fume-proof mask when welding as the fumes generated
during welding include harmful gases and dust. Also be careful that the wind direction
is not such that it will cause fumes to be inhaled and always operate the equipment in
a well-ventilated area.
Warning: Electric Shock
Do not operate the equipment with any doors or covers open.
Do not touch wirings or any electric parts inside the equipment during operation.
Do not touch the equipment during operation if the equipment or your body is wet.
Be sure to stop the engine whenever touching Welding output terminals such as
when installing or removing welding cables.
Do not connect welding cables to any part other than Welding output terminals.
Do not insert any metallic objects, such as pins or wires, into AC output receptacles.
Always be sure to turn off all circuit breakers before installing or removing devices
using AC output receptacles.
Always be sure to repair the fault when the earth leakage circuit breaker operates.
Always be sure to stop the engine before performing any equipment check or
maintenance.
Warning: Fire
Always be sure to stop the engine when inspecting fuel or refueling, and absolutely
never perform such tasks near fire or other open flames or sparks. Wait until the
engine has completely cooled before inspecting fuel or refueling.
Always be sure to wipe away any spilled fuel or oil.
Absolutely never use the equipment if there is a fuel, oil or cooling water leak, and be
sure to always repair the leak before using.
Absolutely never inspect or perform maintenance to the equipment near fire or other
open flames or sparks.
Keep any ignitable items (such as fuel, gas and paint) or inflammable items away
from the equipment because the muffler, exhaust fume and other parts attain high
temperatures.
Keep any ignitable items (such as fuel, gas and paint) or inflammable items away
from the work area due to the scattering of weld spatter that occurs during welding.
Provide at least 1 meter (3 feet) of distance between the equipment and walls and
other obstacles, and operate the equipment on a flat surface.
Allow the equipment to cool before covering with protective covers and similar items.
Do not ground wiring of earth leakage circuit breakers of the equipment to piping that
contains through flammable material.

Warning: Injury
Do not operate the equipment with any doors or covers open. There is a danger of
hair, body parts and other items being caught up in moving parts such as cooling
fans and belts.
Do not modify the equipment and do not operate with parts removed.
Always be sure to stop the engine before performing any equipment check or
maintenance.
The lifting lug is designed to be used only for lifting the equipment. Do not lift the
equipment with any heavy items (such as a trailer, gas canister and additional fuel
tank) added to the equipment.
Warning: Injury to Eyes and Skin
Use protective gear, such as rubber gloves, when inspecting or replacing the battery
due to the dilute sulfuric acid in the battery fluid. Be sure that fluid does not contact
eyes, or on skin or clothing.
If battery fluid gets into the eyes, or on the skin or clothing, immediately wash with a
large amount of water, and always be especially sure to seek medical attention if it
gets into the eyes.
Warning: Explosion
Do not operate the equipment or recharge the battery when the battery fluid level is
below the lower level.
Do not generate any sparks near the battery and do not allow any fire or other open
flames near the equipment because the battery generates ignitable gas.
Warning: Electromagnetic Interference
Persons using a heart pacemaker are not allowed near the welder or welding work
area while welding is being performed without the permission of a doctor. The welder
generates a magnetic field while energized that can negatively affect pacemaker
operation.
Caution: Suffocation from Exhaust Fume
Do not direct the engine exhaust towards passersby, private homes or similar
persons/locations because the engine exhaust fume includes components that are
harmful to humans.
Caution: Electric Shock
Do not sprinkle water on the equipment and do not use where exposed to rain and
thunder.
If wearing gloves, be sure to always wear gloves with dry insulation properties. Do
not wear gloves that are damaged or wet.

Caution: Burn
The engine, muffler and similar parts are extremely hot during operation and
immediately after stopping the equipment. Never touch hot parts.
Never open the radiator cap during operation or immediately after stopping the
equipment. Hot cooling water and steam will spurt out.
Always be sure to stop the engine and allow it to cool before inspecting or changing
the engine oil. Opening the oil gauge or oil plug during operation will result in hot oil
spurting out.
Always be sure to wear leather gloves, apron, shoe covers, arc-proof glasses (face
shield), safety shoes, hard hat and long-sleeve clothing to protect against the
scattering of weld spatter that occurs during welding.
Caution: Injury
Use this equipment with it situated on a stable level surface so that it is prevented
from moving.
Do not move the equipment during operation.
Always be sure to turn off the switches of all devices using the equipment and turn off
the equipment circuit breakers before starting the engine.
Always be sure to turn off the power switches of all devices using the equipment
when turning on the equipment circuit breakers. Leaving on the power switch of a
device using the equipment when the equipment circuit breakers are turned on could
result in the sudden operation of the corresponding device.
Do not leave on the power switch of a device using the equipment and do not
connect a device to an AC output receptacle.
Always be sure to use the lifting lug when lifting the equipment, and lift slowly and
directly straight above.
Wear a helmet, safety shoes, gloves and similar protective gear when performing
lifting work. Do not stand or get under the equipment while it is suspended.
Securely fix the equipment with rope or similar item so that it cannot move when
transporting by truck or other vehicle.
Caution: Injury to Eyes and Skin
Always be sure to wear arc-proof glasses, clothes that completely cover the skin and
other protective gear when welding to protect the eyes and skin from harmful light
rays generated during welding.
Caution: Physical and Secondary Damage
Do not use the equipment for any improper applications. Improper usage can result
in an accident or malfunction.
Do not connect the AC power source to indoor wiring.
If using the equipment as a power source for medical equipment, you must check
with the medical equipment manufacturer, doctor and hospital before using the
equipment.
Caution: Damage to the equipment or other properties
Do not use anything other than the specified optional device because they may
cause malfunctions.
