Chisel angle (when chipping,
scaling or demolishing)
NOTE: This function does not work if the acceleration
does not reach the predetermined one when the tool
is swung.
NOTE: If the bit is swung at the predetermined
acceleration during chipping, scaling, or demolishing,
the motor is forcibly stopped. In this case, release
the switch trigger, and then pull the switch trigger to
restart the tool.
The chisel can be secured at the desired angle. To
change the chisel angle, rotate the action mode chang-
ing knob to the O symbol. Turn the chisel to the desired
angle.

place by turning it slightly.
