8. Other adjustments
(1) Adjusting the ON timing of the engine oper-
ation (run) lamp.
IMPORTANT
Turn the
counterclockwise
operating speed until the engine run
lamp turns on.
In order to prevent the lamp from
blinking (turning on/off when the load
changes after setting the rated speed),
turn it
counterclockwise direction.
(2) Adjusting the ON timing of the initial speed lamp (crank lamp).
IMPORTANT
Turn the crank potentiometer counterclockwise at the crank speed until the crank lamp turns on.
In order to prevent the lamp from blinking (turning on/off when the load changes after setting
the rated speed), turn it another 90° in the counterclockwise direction.
(3) Adjusting the ON timing of the engine overspeed lamp.
IMPORTANT
Push the test button at the engine operating speed and slowly turn the overspeed
potentiometer counterclockwise until the engine overspeed lamp turns on and the engine
shuts off. It will be set to a speed around 15% higher than the engine operating speed.
IMPORTANT
After all adjustments are complete, restart the engine and check whether the start-up, no load
and load characteristics are stable.
In order to prevent the lamp from blinking (turning on/off when the load changes after setting
the rated speed), turn it another 90° in the counterclockwise direction.
9) Adjusting the starting fuel (minimizing exhaust gas)
(1) Crank speed switch ON  adjust crank speed to 800 rpm  turn the starting fuel potentiometer coun-
terclockwise until the engine speed drops.  For the sake of stability, turn it another 15° in the clock-
wise direction.
CAUTION
If the amount of exhaust gas is not excessive when starting the engine, we recommend
adjusting the starting fuel potentiometer to a higher setting in the 5 o'clock direction.
If set too low, startability worsens and immediately after starting the engine, overshoot may
occur and cause the engine to exceed the set overspeed value.
