2. How to bore (Fig. 20)
(1) Connect the plug to the power source.
(2) A spring is installed in the center pin.
Push it lightly to the wall or the fl oor straight.
Connect the core bit tip fl ush to the surface and start
operating.
(3) When boring about 5 mm in depth the position of the hole
will be established. Bore after that removing the center
pin and the guide plate from core bit.
CAUTION
When removing the center pin and the guide plate,
turn OFF the switch and disconnect the plug from the
receptacle.
Application of excessive force will not only expedite
the work, but will deteriorate the tip edge of the drill bit,
resulting in reduced service life of the rotary hammer.
3. Dismounting (Fig. 21)
Remove the core bit shank from the rotary hammer and
strike the head of the core bit shank strongly two or three
times with a hammer holding the core bit, then the thread
becomes loose and the core bit can be removed.
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/off )
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 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.
