After the hole is made, retract the tool from the workpiece, and press STOP
to turn off the motor. Before you move the
machine, set the MAGNET switch to ‘O’ to
turn off the base.
After the work is finished and the motor turned off, set the gear switches to the
opposite position. Then, turn on the motor and let it operate for a while with no load
to improve lubrication. Next, turn off the motor and the base, and then unplug the
power cord. Clean the machine and the tool, and then remove the machine from the
work area.
