You can switch functions to the 3 modes of
"hammering only, "rotation + hammering", and
"rotation only" by turning the change lever while
pressing the push button. Set the ▲ mark position
of the change lever to that of the mode to be used.
CAUTION:
Before operating the change lever, check and make
sure that the motor has stopped.
A failure can occur if it is operated while the motor
is running.
To operate the change lever, press the push button,

Switch the change lever without mistake. If it is
used at a position halfway, there is a fear that the
service life of the switching mechanism may be
shortened.
