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 Weld output terminals such as 
when installing or removing welding cables. 
• Do not connect welding cables to any part other than Weld output terminals. 
• Do not insert any metallic objects, such as pins or wires, into AC output 
receptacles or remote control
l
er connectors. 
• Always be sure to turn off all breakers before installing or removing devices 
using AC output receptacles. 
• Always be sure to repair the corresponding earth leakage location when earth 
leakage relay operate. 
• Always be sure to stop the engine and remove the engine key before performing 
any equipment check or maintenance. 
• Ground every grounding terminal to the earth as set out in the manual. If even 
one of all is disconnected by mistake or accident, it will be much more dangerous 
for human injury or burns than the NO RELAY case, because leaking current 
inevitably goes through the body. 
• Even though all the terminals of the loads have been grounded to the earth, the 
bonnet (canopy) grounding terminal should be grounded to the earth. 
• Grounding should be made after the engine is stopped. 
 
  
 
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 flame. Wait until the 
engine has completely cooled before inspecting fuel or refueling. 
• Always be sure to wipe up 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 flame. 
• 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. 
 
 
1. Safety Precautions 





 
- 3 - 
Warning: Fire 
• 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 relay of the equipment to piping that 
passes 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 and remove the engine key before performing 
any equipment check or maintenance. 
 
  
 
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 get into 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 flame 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. 
• If wearing gloves, be sure to always wear gloves with dry insulation properties. 
Do not wear gloves that are damaged or wet.

5-1. VRD (Voltage Reduction Device) 
The equipment includes a voltage reduction device 
on the weld output side. The voltage reduction 
device reduces the output voltage of the welder 
when welding is paused in order to further increase 
safety when welding in locations with high humidity, 
elevated locations, extremely confined spaces near 
possible hazards, and similar conditions. 
When the VRD switch is set to "ON" and not welding, the voltage reduction device 
reduces the voltage of the Weld output terminals to 35 V or less. 
When welding is started, the voltage-reduction function is cancelled and the 
equipment returns to the reduced voltage status when welding is completed. Turning 
the VRD switch to "OFF" also cancels the voltage-reduction function. 
The green VRD lamp ("BELOW 35V" side) lights up when weld output voltage is less 
than 35 V and the red lamp ("AT OR ABOVE 35V" side) lights up when the voltage is 
35 V or more. 
 
<Note> 
• The VRD is only for weld output. It does not function for AC generated output 
voltage. 
 
5-2. Idle Control 
The equipment includes an idle control function. You 
can use the idle control switch to select an engine 
speed setting of "AUTO","HIGH". 
 
(1) Auto Idle 
The equipment includes an auto idle function in order to reduce noise, save fuel, and 
reduce exhaust gas emission. 
You can set the idle control switch to "AUTO" so that the engine operates at low 
speed when not welding or using the equipment as a power source. 
When you start to weld or use as an AC power source, the engine automatically 
increases to high speed. When in a no-load condition, the engine automatically 
returns to low speed after approximately eight seconds of high-speed operation. 
 
<Note> 
• Set the idle control switch to "HIGH" if using a high capacity motor, precision 
instruments or AC load with an attached magnetic switch. 
• Set the idle control switch to "HIGH" if using as an AC power source of a device 
of 0.5 A or less because the engine might not reach a high speed as speed 
control does not operate at that level.

(Refer to section "13．Troubleshooting" for Error Code Display.) 
 
<Note> 
• There may be a case that the lamp will not flash, depending on the weather 
condition. 
 
5-8. Earth Leakage Relay and Grounding 
 
  
 
Warning: Electric Shock 
• Ground every grounding terminal to the earth as set out in the manual. If even 
one of all is disconnected by mistake or accident, it will be much more dangerous 
for human injury or burns than the NO RELAY case, because leaking current 
inevitably goes through the body. 
• Even though all the terminals of the loads have been grounded to the earth, the 
bonnet (canopy) grounding terminal should be grounded to the earth. 
• Grounding should be made after the engine is stopped. 
• Always be sure to repair the corresponding earth leakage location when earth 
leakage relay operate. 
Warning: Fire 
• Do not ground wiring of earth leakage relay of the equipment to piping that 
passes through flammable material. 
 
The equipment is provided with the earth leakage relay in the earth leakage circuit 
breaker to detect any leakage arisen due to the troubles as insulation failure of the 
load while the generator is running. And cutting off the circuit for protection against 
any accident such as electrical shock resulting from the trouble. 
 
The specifications of the earth leakage relay: 
• Rated Sensitive Current: 30mA (or below)                                               
(Grounding resistance: 500Ω or below)

<Note> 
• Securely crimp the crimped terminals and securely connect the welding cables. 
Using insufficiently crimped terminals or loosely connected cables can result in 
heat generation from poor connection, thereby causing burnout of the weld 
output terminals. 
• Be sure to always securely crimp the crimped terminals on the cables connected to 
the Weld output terminals. Not using crimped terminals and simply wrapping 
stripped cable around the weld output terminal can result in heat generation from 
poor connection, thereby causing burnout of the weld output terminals and a short 
circuit due to contact of the cable core with the equipment body. 
• Keep your welding cable and electrode holder in good condition. Repair or replace 
any damaged insulation. 
 
  
 
8-4. Duty Cycle 
The duty cycle is the percentage of time the load is being applied in a 10-minute 
period. For example a 60% duty cycle, represents 6 minutes of load and 4 minutes 
of no-load in a 10-minute period. 
<Note> 
• Continuing to weld beyond the rated duty cycle with the rated output can result in 
equipment overheating and corresponding malfunctions. 
 
  
 
8-5. Welding Work 
 
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: Fire 
• 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. 
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: Injury to Eyes and Skin 
• Always be sure to wear arc-proof glasses (refer to the table below), 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.

• Do not touch the equipment during operation if the equipment or your body is wet. 
• 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. 
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 flame. Wait until the 
engine has completely cooled before inspecting fuel or refueling. 
• Always be sure to wipe up 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 flame. 
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 get into 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 minimum level. 
• Do not generate any sparks near the battery and do not allow any fire or other 
open flame near the equipment because the battery generates ignitable gas. 
 
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 before performing any equipment check or maintenance. 
• 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. 
 
 
Refer to the table of the next page to perform inspection when the equipment is 
operating poorly. 
If you cannot resolve a problem after inspecting the equipment, request repair at 
the retail outlet where the equipment was purchased.
