SELECT OPERATION MODE

Pressing the changeover switch allows the selection of
rotation speed and the auto stop function.
○ Rotation speed (Low mode/Normal mode) (Fig. 13)
Select either Low mode or Normal mode and operate the
tool in the selected speed.
○ Auto stop mode (on/off ) (Fig. 14)
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. 14)
(At the same time the auto stop lamp will blink.)
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 .)

REACTIVE FORCE CONTROL
8 3
This product is equipped with a Reactive Force Control
9 4
(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 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.

ABOUT THE PROTECTION
FUNCTION
This tool has a built-in protection circuit for preventing
damage to the unit in the event of an abnormality. Depending
on the following, the display lamp and the indicator lamp will
fl ash, and the unit will cease to operate. Verify the problem
indicated by the fl ashing and take the necessary steps to
correct the problem.
When pressing the changeover switch, do so when the
switch is not being pulled.

When the RFC is triggered and the motor stops, turn
off the tool's switch and remove the cause of the
overburdening before continuing operation.
