Always make sure that the work-
piece is secured before operation.
CAUTION:
Do not pull the tool out forcibly
even the bit gets stuck. Loss of control may
cause injury.
CAUTION:
The dust collection system is
intended for drilling in concrete only. Do not use
the dust collection system for drilling in metal or
wood.
CAUTION:
When using the tool with the dust
collection system, be sure to attach the filter
to the dust collection system to prevent dust
inhalation.
CAUTION:
Before using the dust collection
system, check that the filter is not damaged.
