Wet Drilling - Hilti DD 110-W Manual De Instrucciones

5. Press the on / off switch on the power tool.
6. When beginning drilling, apply only light pressure
until the core bit has centered itself and then in-
crease the pressure. Drill to a depth of 3-5 mm to
form a guide kerf (optional operation).
7. Switch the machine off by releasing the on / off
switch and then wait until the core bit has stopped
rotating (optional operation).
8. Remove the hole-starting aid from the core bit (op-
tional operation).
9. Position the core bit in the guide kerf and then
press the on / off switch to continue drilling (optional
operation).
10. Allow the vacuum cleaner to run for a few seconds
after switching off the machine in order to ensure
that the remaining dust is removed.
7.4 Dry drilling without dust removal
NOTE
Use slotted core bits when drilling without a dust removal
system.
NOTE
Remove the dust removal attachment or secure it to
prevent rotation.
NOTE
The optional operations are to be carried out when the
two-part hole starting aid is used.
CAUTION
Unplug the supply cord from the power outlet before
removing the core.
DANGER
Wear respiratory protection.
NOTE
Dust is released in all directions. Drilling without a dust
removal system, especially overhead drilling, is very un-
pleasant and optimum performance is not achieved.
Overhead drilling without use of dust removal system
is therefore not recommended. For dry coring it is recom-
mended that the dust removal attachment and a suitable
vacuum cleaner are always used.

2. Fit the hole-starting aid (optional operation).

to be drilled (hole center).
5. Press the on / off switch on the power tool.
6. When beginning drilling, apply only light pressure

form a guide kerf (optional operation).
7. Switch the machine off by releasing the on / off
switch and then wait until the core bit has stopped
rotating (optional operation).
8. Remove the hole-starting aid from the core bit (op-
