Hammerdrilling (fig. 1)
DRILLING WITH A SOLID BIT
1. Set the mode selector switch (d) to the
hammerdrilling position.
2. Insert the appropriate drill bit.
NOTE: For best results use high quality carbide-
tipped bits.
3. Adjust the side handle (i) as required.
4. If necessary, set the drilling depth.
5. Mark the spot where the hole is to be drilled.
6. Place the drill bit on the spot and switch on the
tool.
7. Always switch off the tool when work is finished
and before unplugging.
Drilling with a Core Bit (fig. 1)
1. Set the mode selector (d) to the hammerdrilling
position.
2. Adjust the side handle (i) as required.
3. Insert the appropriate core bit.
4. Assemble the centredrill into the core bit.
5. Place the centredrill on the spot and press the
variable speed switch (a). Drill until the core
penetrates into the concrete approx. 1 cm.
6. Stop drilling and remove the centredrill. Place
the core bit back into the hole and continue
drilling.
7. When drilling through a structure thicker than
the depth of the core bit, break away the round
cylinder of concrete or core inside the bit at
regular intervals. To avoid unwanted breaking
away of concrete around the hole, first drill a
hole the diameter of the center drill completely
through the structure. Then drill the cored hole
halfway from each side.
8. Always switch off the tool when work is finished
and before unplugging.
Rotary Drilling (fig. 1)
1. Set the mode selector switch (d) to the rotary
drilling position.

4. Insert the appropriate screwdriver bit. When
driving slotted head screws always use bits with
a finder sleeve.
5. Gently press the variable speed switch (a) to
prevent damage to the screw head. In reverse
(LH) rotation the tool speed is automatically
reduced for easy screw removal.
6. When the screw is flush with the workpiece,
release the variable speed switch to prevent
the screw head from penetrating into the
workpiece.
