2. Insert the bit shank into the tool holder (f), and
press and turn the bit slightly until the sleeve
snaps into position.
3. Pull on the bit to check if it is properly locked.
The hammering function requires the bit to be
able to move axially several centimetres when
locked in the tool holder.
4. To remove a bit pull back the tool holder locking
sleeve (f) and pull the bit out of the tool holder.
Selecting the Operating Mode
(fi g. 5)
The tool can be used in two operating modes:
Hammerdrilling: for concrete and
masonry drilling operations.
Hammering only: for light chipping,
chiselling and demolition applications.
In this mode the tool can also be used
as a lever to free a jammed drill bit.
1. To select the operating mode, press the safety
lock (e) and rotate the mode selector switch
(d) until it is points to the symbol of the required
mode.
2. Release the safety lock and check that the
mode selector switch is locked in place.
Indexing the Chisel Position (fi g. 5, 6)
The chisel can be indexed and locked into 8 different
positions (fig. 6).
1. Rotate the mode selector switch (d) until it
points upward.
2. Rotate the chisel in the desired position.
3. Set the mode selector switch (d) to the
“hammering only” position.
4. Twist the chisel until it locks in position.
Setting the Electronic Speed and
Impact Control Dial (fi g. 2)
Turn the dial (b) to the desired level. The higher the
number, the greater the speed and impact energy.
With dial settings from 1 (low) to 5 (full power) the
tool is extremely versatile and adaptable for many
different applications. The required setting is a matter
of experience. e.g.:
— when chiselling or drilling in soft, brittle
materials or when minimum break-out is
required, set the dial to 1 or 2 (low);
— when breaking or drilling in harder
materials, set the dial to 5 (full power).
D25600
With dial settings from 1 to 7 the tool allows a further
fine-adjustment to the choice of application.
Assembling and Fitting the Side
Handle (fi g. 7–10)
The side handle (h) can be mounted in front or in
rear position on either side of the machine to suit
both RH- and LH-users.
CAUTION: Always operate the tool with
the side handle properly assembled.
MOUNTING IN FRONT POSITION (FIG. 7, 8)
1. Snap the steel ring (p) over the collar (g) behind
the tool holder (f). Squeeze both ends together,
mount the bush (n) and insert the pin (o).
2. Place the side handle clamp (m) and screw on
the clamp wheel (i). Do not tighten.
3. Screw the side handle (h) into the clamp wheel
and tighten it.
4. Rotate the side handle mounting assembly to
the desired position. For drilling horizontally
with a heavy drill bit, we recommend to place
the side handle at an angle of approx. 20° for
optimum control (fig. 8).
5. Lock the side handle mounting assembly in
place by tightening the clamp wheel (i).
MOUNTING IN REAR POSITION (FIG. 9, 10)
The rear position is particularly useful when drilling
overhead or down into a floor. Refer to fig. 10.
1. Unscrew the side handle (h) and remove it
from the front position. Leave the side handle
mounting assembly in front position so that the
depth adjustment rod can still be used.
2. Screw the side handle directly into one of the
rear side handle positions (j) on either side of the
tool.
Setting the Drilling Depth (fi g. 11)
1. Insert the required drill bit.
2. Loosen the clamp nut (q) and fit the depth
adjustment rod (k) through the hole in the side
handle clamp.
3. Push the drill bit into a surface at a right angle
and adjust the depth adjustment rod (k) as
shown.
4. Tighten the clamp nut (q).
