(3) Breaker Trip Selector Switch
This switch is for selecting the tripping order of the three-phase and single-phase breaker
when there is a short circuit or overload on the load side. If the three-phase or single-phase
breaker is selected for precedence in tripping, the selected breaker will trip first when the
total generator output exceeds the rated capacity.
After that, the other breaker will also trip if the generator output exceeds the rated capacity
again.
Switch Selection

": The single-phase breaker trips first followed by the three-phase breaker.
(4) Ammeter Selector Switch
This switch is for selecting the output current indicated by the ammeter. Change the switch
to display the following output terminal current on the ammeter.
Switch Selection
"L1+U": Three-phase L1 phase + Single-phase three-wire U phase (total)
"L2": Three-phase L2 phase
"L3+W": Three-phase L3 phase + Single-phase three-wire (total)
< NOTE >
If measuring the output current for a single-phase three-wire type, turn the ammeter selector
switch to "L1+U" or "L3+W". The voltage cannot be accurately measured if set to "L2".
Voltage Regulator/Engine Speed Switch
(1) Voltage Regulator
This dial is for regulating voltage output by the generator. Turn the dial
clockwise to increase the voltage and counterclockwise to decrease it.
(2) Engine Speed Switch
Throttle Switch
This switch is for changing the engine speed. Set to IDLING when starting,
warming up and cooling down the engine, and set to RUN during rated
operation.
5-5. Spill Containment
WARNING : INJURY
Do not open the check door during operation. Be careful of pinching or
catching of moving parts such as the cooling fan and fan belt.
Always be sure to stop the engine and remove the starter key when
performing inspection or maintenance.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after
stopping the engine as they are still extremely hot.
The bed of this generator is equipped with a spill containment (structure for preventing
leakage of liquids) so that any spilled liquid will not leak to outside of the generator when oil or
fuel is spilled or leaks. Before starting operation, check if there is accumulated liquid in the
spill containment. Flush out any liquid that has accumulated. Refer to section "8-5. Checking
the Spill Containment" for inspection procedures.
