Mode Selector Dial
The mode selector dial allows the tool
to be set for various applications as
listed in the following chart, (Fig. 12).
Do not operate the
selection dial until
the tool comes to a complete stop.
Shifting during rotation of the chuck can
cause damage to the tool.
When using demolition or chipping bits
such as bull points, chisels, spades,
gouges, etc. the “Hammer Only” mode
must be selected.
“Vario-Lock”
The Vario-Lock position is intended for
u s e w i t h c h i p p i n g b i t s s u c h a s b u l l
points, spades, gouges, etc. Choose a
position which is best suited for your
operation.
Turn the mode selector dial, to the
“vario-lock” setting. Next, rotate the
locking sleeve, along with the accessory,
to the desired position. Then turn the
mode selector dial to the “hammer only”
setting and slightly turn the locking
sleeve to have it automatically lock into
a definite position (Fig. 13).
Slip Clutch
The tool has an internal pre-set slip
clutch. The output spindle will stop
r o t a t i n g i f t h e a c c e s s o r y b i n d s a n d
overloads the tool.
Kickback Control
The rapid shut-off feature enables better
control and improves user’s comfort. The
power tool automatically shuts off in case
of sudden and unexpected rotation of the
power tool around the drilling axis (for
example jamming of the drill bit in
reinforcing steel or wedging application
tool).To restart the machine, release the
On/Off switch and then press again
twice.
Kickback Control can activate only when
the power tool is running at maximum
operating speed and can rotate freely
around the drill bit axis.
Vibration Dampening
The integrated vibration damping function
reduces the generated vibration.
