OIL WARNING SYSTEM
When the oil level falls below the lower level, the engine stops
automatically. Unless you refill with oil, the engine will not start again.
FIG.2
ENGINE AND FUEL COCK SWITCH
The engine switch controls the ignition system. FIG.3
① ON (run)
Ignition circuit is switched on. The engine can be started.
②OFF(stop)
Ignition circuit is switched off. Theengine will not run.
ELECTRIC START SWITCH
The engine switch controls the ignition system. FIG.4
①RUN
Ignition circuit is switched on. The engine can be started.
②STOP
Ignition circuit is switched off. Theengine will not run.
③START
Starting circuit is switched on. The starter motorstarts.
ECONOMY CONTROL SWITCH
When the economy control switch is turned ON, the economy control
unit will control the engine speed according to the connected load. The
results are more efficient fuel consumption and less noise. FIG.5
DC CIRCUIT PROTECTOR
The DC circuit protector turns off automatically when the load exceeds
the generator’s rated output. FIG.6
CAUTION:
Reduce the load to within specified generator’s rated output if the DC
circuit protector turns off.
