○ Auto stop mode (on/off ) (Fig. 30)
This product is equipped with an auto stop function
to support continuous drilling work. The function
features a memory mode for storing the work time
for drilling from switch ON to switch OFF, and an auto
stop mode that automatically stops the motor from the
second drilling onward should the work exceed the
stored work time while the switch is ON.
AUTO STOP FUNCTION
In selection mode, pressing the button for longer than two
seconds will move to memory mode. (Fig. 30)

Conduct drilling when the auto stop lamp is fl ashing. The
time between switching ON and switching OFF is stored
by the tool.
(At the same time, the auto stop lamp will light up.)
Conduct drilling when the auto stop lamp is fl ashing.
Continuous drilling is possible as the memory storage time
will be recorded by the tool until the auto stop function's
auto stop mode is cancelled.
The auto stop function is cancelled by pressing the
changeover switch once again for over two seconds.
(At the same time, the auto stop lamp will switch off .)
CAUTION
○ Switch ON the tool once you place the tip of the tool
on the work material.
○ The rotation speed and the level at which the switch is
pulled during drilling is not stored to memory.
○ Fully carry out drilling in one go during auto stop
mode.
○ The motor will stop even if you switch OFF within the
memory storage time.
○ When you switch OFF within the memory storage
time, the count will be reset. If you rework a task in
which a hole has been partially drilled, the memory
storage time will be fully recounted.
○ The auto stop function will remain active until
canceled.
REACTIVE FORCE CONTROL
This product is equipped with a Reactive Force Control
(RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the
tool body is reduced by activation of the slip clutch or by
stopping of the motor by the sensor built into the tool body.
If the motor is stopped because of overburdening detection
by the controller, the RFC indicator lamp (display lamp) will
blink while the switch is pulled. In addition, the lamp will
continue blinking for approximately three seconds after
the switch is released. The motor will remain stopped
while the lamp is blinking. (Fig. 31)
Because the RFC feature may not activate or its
performance may be insuffi cient depending on the
working environment and conditions, be careful not to
suddenly overburden the tool bit while operating.
● Possible causes of sudden overburdening
Tool bit biting into material
Impact against nails, metal or other hard objects
Tasks involving prying or any excess application of
pressure, etc.
Also, other causes include any combination of the
aforementioned.
