Before Use - Hilti DD 110-D Operating Instructions Manual

6 Before use

en
CAUTION
The mains voltage must comply with the specification
given on the type identification plate. Ensure that the
power tool is disconnected from the electric supply.
DANGER
When drilling through walls, cover the area behind
the wall, as material or the core may fall out on the
other side of the wall. When drilling through ceilings,
secure (cover) the area below as drilled material or
the core may drop out and fall down.
CAUTION
Do not transport the machine while it is connected to
the electric supply. Disconnect the supply cord plug
from the power outlet.
6.1 Positioning the side handle 2
CAUTION
Disconnect the supply cord plug from the power out-
let.
1. Release the side handle clamping band by turning
the handle counterclockwise.
2. Pivot the side handle into the desired position.
3. Secure the side handle by turning the grip clockwise.
6.2 Fitting the diamond core bit 3
DANGER
Do not use damaged core bits. Check the core bits for
chipping, cracks, or heavy wear each time before use.
Do not use damaged tools. Fragments of the workpiece
or a broken core bit may be ejected and cause injury
beyond the immediate area of operation.
NOTE
Diamond core bits must be replaced when the cutting
performance and/or rate of drilling progress drops sig-
nificantly. This generally is the case when the segments
reach a height of less than 2 mm.
CAUTION
To avoid injury, use only genuine Hilti core bits and
DD 110-D accessories. If using a machine with a BI+
chuck, only genuine Hilti core bits may be used with
it.

CAUTION
The core bit may get hot during use or during sharpening.
There is a risk of burning your hands. Wear protective
gloves when changing the core bit.
CAUTION
Disconnect the supply cord plug from the power out-
let.
CAUTION
Check that the hole-starting aid is securely positioned
in the core bit.
CAUTION
When using the hole-starting aid, allow the machine
to run only when the hole-starting aid is in contact
with the working surface.
NOTE
The BR, BT, M16 and M27 chucks require use of a
suitable open-end wrench.
The chuck, the adapter and the cutting tool must be clean
and free of dirt and dust.
1. Open the chuck (BI+) by turning it in the direction of
the open brackets symbol.
2. Push the diamond core bit into the chuck (BI+) from
the front, turning the core bit until the teeth in the
chuck engage with the core bit.
3. Close the chuck (BI+) by turning it in the direction of
the closed brackets symbol.
4. Check that the diamond core bit is securely mounted
in the chuck by pulling on the core bit and attempting
to move it from side to side.
6.3 Fitting the dust removal attachment (optional)
6.3.1 Socket cutter 4
1. Push the hole-starting aid, point first, as far as it will
go, into the connection end for socket cutters with
dust removal.
2. Fit the connection end into the chuck in accordance
with the instructions for fitting a diamond core bit.
3. Push the locking sleeve and the dust removal at-
tachment back toward the power tool.
4. Fit the socket cutter onto the connection end.
5. Push the dust removal attachment forward until it is
in contact with the socket cutter and then secure it
in this position by sliding the locking ring toward the
socket cutter.
6. Check that the dust removal unit is free to rotate
relative to the power tool.
