The equipment includes a spill containment (structure that collects leaking liquid)
in order to prevent leaking liquid from getting outside of the equipment if oil, fuel
or other liquid should leak. Before starting operation, check if there is any fluid
accumulated in the spill containment and drain any accumulated liquid. (Refer to
section "11.(7) Draining Liquid from the Spill Containment".)
<Note>
• It is necessary to periodically drain the liquid from within the equipment because
any rainwater that leaks into the equipment also accumulates in the spill
containment.
• Although the fluids that can leak internally consist of oil, fuel and cooling water, the
spill containment does not have a function that can separate rainwater that has
leaked into the equipment from these internally leaked fluids. Properly dispose of
liquid drained from the spill containment in a manner according to the applicable
laws and regulations.
5-4. ECO Drive
The equipment includes an eco drive function in order to reduce noise, save fuel,
and reduce exhaust gas emmision.
When the idle control switch is set to "ECO" and only welding is being performed,
the engine operates at an optimal speed corrsponding to the weld output and it
automatically returns to low speed when welding is stopped.
The eco drive display lights up during eco drive to indicate that operation is
environmentally considerate.
<Note>
• If using for only welding, the engine will attain the optimal speed to match the weld
output when you start to weld.
• If using only as an AC power source, the engine speed will attain a uniform speed
that is slightly less than the rated speed.
• The engine speed changes to high speed
when simultaneously welding and using
as AC power source.
• Speed automatically returns to low speed
when not using for welding work or as an
AC power source.
• Set the idle control switch to "HIGH" if
using a high capacity motor, precision instruments orAC load with an attached
magnetic switch.
• Set the idle control switch to "HIGH" when using a device of 1A or less because
the engine might not reach a high speed as the speed control function does not
operate at that level.
• Set the idle control switch to "LOW/HIGH" or "HIGH" if welding or using as an AC
power source in an intermittent manner.
• Set the idle control switch to "LOW/HIGH" or "HIGH" if simultaneously performing
high-current welding and using as an AC power source.

5-5. 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 25 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.
The green VRD lamp ("ON" side) lights up when weld output voltage is less than
25 V and the red lamp ("OFF" side) lights up when the voltage is 25 V or more.
<Note>
• The VRD is only for weld output. It does not function for AC generated output
voltage.
• Arc start may be difficult to perform when the VRD is operating. In such cases, set
the VRD switch to "OFF".
Operation Check of the VRD If using the voltage
reduction device, Shindaiwa recommends
performing an operation check approximately
once every six months.
Perform the operation check according to the
following procedures.
1) Set the VRD switch to "ON".
2) Start the engine and set the speed control
switch to "HIGH". (Refer to section "7-1.
Starting the Engine")
3) While operating the VRD Button, check the
operation by referring to the following table.

If the operation differs from the display status, it is probable that there is a fault in
the voltage reduction device. Request repair at the retail outlet where the
equipment was purchased.
5-6. Weld Mode Selector
You can select weld mode of "DROOP" or "CC" in accordance with the type of
welding being performed.
DROOP (Drooping Characteristic)
The weld current can be adjusted by manipulating the
welding rod due to being able to increase or decrease
the current for changing the arc length, thereby allowing
you to adjust the arc status and weld beads.
The arc start is good and the arc seems to be strongly
felt. This mode is optimal for welding work such as pipe
welding or when using special welding rods.
CC (Constant Current)
Welding can be performed at a constant uniform current even if the arc length
changes due to a shaky hand or similar cause to provide a stable arc that is not
easily extinguished.
Welding can be performed at a specified current value without being affected by
the length or thickness (thinness) of the welding cable. This mode is optimal for
general welding as the stable arc reduces the amount of spatter.
5-7. Meter
The equipment includes a DC meter that provides digital display of weld current,
and an AC meter that provides digital display of voltage, current and frequency of
3-phase generated output.
The AC meter is equipped with an AC meter selector that can be switched to
display 3-phase voltage, 3-phase current or frequency.
<Note>
• When not welding, the weld current meter displays the current value set by the
weld current adjustment dial. (Preset lamps are lit up.)
• During welding, the weld current meter displays the actual current value. (Actual
lamps are lit up.)
• During operation, "3-PHASE VOLT." of the AC power meter displays the 3-phase
200/220V output voltage of the AC power source at all times regardless of whether
the breaker is "ON" or "OFF".

The equipment includes monitor lamps for
"WATER TEMP" , "CHARGE" , "OIL PRESS"
and "SPILL CONTAINMENT" .
If the equipment is normal, the "CHARGE" and
"OIL PRESS" monitor lamps light up when the
starter switch is switched from "STOP" to
"RUN" , and all monitor lamps turn off when the
engine is started. If any error besides that of
spill containment occurs during operation, the
corresponding monitor lamp lights up and the engine is automatically stopped.
If the engine is automatically stopped, return the starter switch to "STOP" and
restart the engine. Watch the lit/unlit status of the monitor lamps the next time an
automatic stop occurs and check the error contents.
(1) Water Temperature Monitor Lamp
The water temperature monitor lamp ("WATER TEMP") lights up and the engine
is automatically stopped if the cooling water temperature becomes irregularly
high during operation. If this occurs, inspect the water level of the sub tank and
add cooling water if the water level is insufficient. (Refer to section "6-2. Cooling
Water Inspection".)
If the cooling water in the sub tank is at the specified level, it is probable that
overloading is the cause. Use within the rated output.
(2) Battery Charge Monitor Lamp
The battery charge monitor lamp ("CHARGE") lights up and the engine is
automatically stopped if battery charge fails during operation. If this occurs, it is
probable that there is fan belt damage or a wiring fault. Request repair at the

Inspection".)
(3) Oil Pressure Monitor Lamp
The oil pressure monitor lamp ("OIL PRESS") lights up and the engine is
automatically stopped if the engine oil pressure drops during operation. If this
occurs, inspect the engine oil level and fill with engine oil until it reaches the
maximum level.
<Note>
• The oil pressure monitor cannot detect oil deterioration.
• Change the engine oil periodically. (Refer to section "11.Inspection/Maintenance".)
• The charge monitor cannot detect battery deterioration or insufficient battery fluid.
Inspect the battery fluid level periodically. (Refer to section "6-6. Battery
Inspection".)
• Inspect the fuses if the engine is automatically stopped and none of the monitor
lamps ("WATER TEMP", "CHARGE" and "OIL PRESS") light up. (Refer to section
"4. Part Names" for fuse location.)
If a fuse has blown, it is probable that there is a fault in an electric part or the wiring.
Request repair at the retail outlet where the equipment was purchased.

(4) Spill Containment Monitor Lamp
The spill containment monitor lamp ("SPILL CONTAINMENT") lights up if the
level of liquid in the spill containment is approximately 70% full (approx. 30L) in
order to ensure that liquid accumulated in the spill containment does not spill out
of the equipment. If this occurs, drain the liquid from the spill containment. (Refer
to section "11. (7) Drain Liquid from Spill Containment")
<Note>
• The engine is not stopped if the spill containment monitor lamp lights up during
operation.
• When the spill containment monitor lamp lights up during operation, stop the
engine, check for fuel, oil and cooling water leakage, and repair as necessary.
• Do not use the equipment with liquid accumulated in the spill containment. Drain
the spill containment before using. (Refer to section "11. (7) Drain Liquid from Spill
Containment")
5-11. Voltage Adjustment Dial
Use the dial for adjusting the output voltage of the AC power source when you
need to adjust the voltage.
The equipment is normally used with the dial set at the center position.
<Note>
• The output current decreases as the voltage
increases. (Use within the rated output
range.)
• Setting higher than the allowable voltage of
devices using the equipment can result in
the malfunction of such devices.
5-12. Earth Leakage Circuit Breaker and Grounding
Warning: Electric Shock
• Be sure to always perform grounding work in all specified locations. Failure to
ground even one specified location can result in leakage current flowing through
the body and a more dangerous situation than if earth leakage protection devices
are not installed.
• Even if the earth leakage breakers of used devices are grounded, be sure to
always ground this equipment by using the earth leakage and case grounding
terminals.
• Always be sure to stop the engine before performing grounding work.
• Always be sure to repair the corresponding earth leakage location when an earth
leakage circuit breaker operates.
Warning: Fire
•Do not ground wiring of earth leakage relay of the equipment to piping that passes
through flammable material.
The equipment includes earth leakage circuit breakers (solidly grounded type) in
order to prevent electric shock. Immediately isolate the electrical circuit if earth
leakage occurs due to insulation failure in devices using the equipment or similar
reason.

(1) Grounding Work
Make sure that a qualified electrician performs grounding work in the following
three locations.
Earth Grounding Terminal of this
Equipment
Perform grounding according to
Class D grounding work of the
Technical Standards for Electrical
Equipment so that the grounding
resistance is 100Ωor less. Use a
ground bar for cable that is 5.5 mm2
or larger.
Bonnet Grounding Terminal of this Equipment
Perform grounding according to Class D grounding work of the Technical
Standards for Electrical Equipment so that the grounding resistance is 100Ωor
less. Cable used in grounding must have a thickness that matches the generator
capacity.
Metallic Case Grounding of Used Devices (Grounding Terminal)
Perform grounding according to Class D grounding work of the Technical
Standards for Electrical Equipment so that the grounding resistance is 100Ωor
less. Cable used in grounding must have a thickness that matches the capacity of
the device used. Grounding resistance of 500Ωor less is possible because this
equipment is equipped with a sensitivity current of 100mA or less and earth
leakage breakers with an operating time of 0.5 sec. or less.
<Note>
• Consult with the retail outlet where the equipment was purchased if you cannot
perform grounding work for devices used or you require ground bars.
• Do not ground the neutral point O terminal of the output terminals.
(2) Shared Grounding
Shared grounding is allowed if it is difficult to ground independently due to site
conditions.
<Note>
• The cable thickness must be the
maximum thickness value required
for the corresponding grounding
location.
• The grounding resistance must be
the minimum resistance value
required for the corresponding
grounding location.
