Hammerdrilling (fig. 1)
DRILLING WITH A SOLID BIT
1. Set the mode selector switch (b) to the
"hammerdrilling" position.
2. Insert the appropriate drill bit. For best results
use high quality carbide-tipped bits.
3. Adjust the side handle (h) 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
1. Set the mode selector (b) to the "hammer
drilling" position.
2. Adjust the side handle (h) as required.
3. Insert the appropriate core bit.
4. Assemble the centerdrill into the core bit.
5. Place the centerdrill 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 centerdrill. 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
28
hole the diameter of the centerdrill completely
through the structure. Then drill the cored hole
halfway from each side.
