SELECT OPERATION MODE
Pressing the changeover switch allows the selection of
rotation speed and the auto stop function.
○ Rotation speed (Low mode/Normal mode)
Select either Low mode or Normal mode and operate the
tool in the selected speed.
○ Auto stop mode (on/o ff )
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.
(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 o ff .)
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.
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.
When the RFC is activated, the two LEDs fl ash red in
a synchronized manner. ( Table 1 ) During the fl ashing,
the motor will be o ff . Press the changeover switch to
recommence operation.
Because the RFC feature may not activate or its performance
may be insu ffi cient depending on the working environment
and conditions, be careful not to suddenly overburden the
tool bit while operating.
● Possible causes of sudden overburdening
1
Tool bit biting into material
2
Impact against nails, metal or other hard objects
3
Tasks involving prying or any excess application of
pressure, etc.
Also, other causes include any combination of the
aforementioned.
