6. Place the centerdrill on the spot and switch on the tool. Drill
until the core penetrates into the concrete approximately
1 cm.
7. Stop the tool and remove the centerdrill. Place the core bit
back into the hole and continue drilling.
8. 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 centerdrill
completely through the structure. Then drill the cored hole
halfway from each side.
9. Always turn the tool off when work is finished and
before unplugging.

Recommendations for Tool Operation
•
When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit. A smooth even flow of material indicates the
proper drilling rate.
•
If drilling thin material or material that is prone to splinter,
use a wood "back-up" block to prevent damage to
the work piece.
WARNING:
•
Do not use this tool to mix or pump easily combustible
or explosive fluids (benzine, alcohol, etc.).
•
Do not mix or stir inflammable liquids
labelled accordingly.
