6.2.3 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 ¹⁄₁₆".
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.
6.2.4 Selecting the speed 5
CAUTION
Do not change gear while the machine is running.
Wait for the spindle to come to a halt.
Set the selector switch according to the core bit diame-
ter used. Turn the selector switch to the recommended
setting (see section "Description") while rotating the core
bit by hand.
6.2.5 Removing the diamond core bit
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.
NOTE
If using a BR, BT, M27 or M16 chuck, prevent rotation of
the chuck and use a suitable open-end wrench to remove
the core bit.
1. Open the chuck (BI+) by turning it in the direction of
the open brackets symbol.
2. Pull the sleeve on the chuck in the direction of the
arrow towards the machine. This releases the core
bit.
3. Remove the core bit.
