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
use with chipping bits such as bull
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. 11).
▶ Slip Clutch
The tool has a internal pre-set slip
clutch. The output spindle will stop
rotating if the accessory binds and
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 actuate again.
Kickack Control can activate only when
the power tool is running at maximum

operating speed and can rotate freely
around the drill bit axis.
Following a few simple tips will reduce
wear on the tool and the chance of
injury to the operator.
NOTE: The high efficiency available
from the rotary hammers can only be
obtained if sharp and undamaged
accessories are used. The "cost" to
maintain sharp and
accessories is more than offset by the
"time saved" in operating the tool with
sharp accessories.
You will extend the life of your bits and
do neater work if you always put the bit
in contact with the workpiece BEFORE
pulling the trigger. During operation,
hold the drill firmly and exert moderate,
steady pressure. Too much pressure at
low speed will stall the hammer. Too
little pressure will keep the bit from
cutting and cause excess friction by
sliding over the surface. This can be
damaging to the drill and bit.
Shanks of all drill bits should be wiped
clean prior to using and immediately
after removing.
Recall these instructions for safe
operation:
Some materials require slow
drilling speeds; whereas, others
require higher speed to produce
the best results.
All work must be supported or
secured before drilling and steady,
even pressure applied in line with
the drill bit.
As the drill bit cuts through the
opposite side, reduce the pressure
and continue running the drill as
the bit is withdrawn.
Materials such as glass, porcelain,
ceramics, tiles, plastics, etc., should be
drilled at low speeds with specially
designed drill bits and lubricants.
If backing block is not used, ease up on
the pressure just before the bit breaks
through the wood to avoid splintering.
Complete the hole from the opposite
side immediately after the point breaks
