4. About the mode select function
Each time the mode selector switch is pushed, the
operation mode changes.
When Silent mode is selected, the Silent mode
indicator lamp lights up.
Silent mode reduces maximum motor RPM enabling
effi cient work with less noise.
If the load increases while the motor is operating in
Silent mode, it automatically changes to Power mode.
Additionally, if the load decreases again, it
automatically returns to Silent mode.
In Power mode, no change is made to Silent mode
even when the load decreases.
