wall.
•

switch (5) and wait until the working speed has
been reached – the green LED (3) lights up.
•
13 Plunge the diamond dry-cutting discs

•
1 / 13 Working direction  of the diamond
cutter.
CAUTION
The diamond dry-cutting disc can become blunt or
damaged due to overheating. An overheated (blue
tarnished) diamond dry-cutting disc can usually no
longer be resharpened.
Î The feed can only be as high as the diamond
dry-cutting disc can wear away the material.
Therefore, do not exert too large a force on the
diamond dry-cutting discs and avoid canting.
Note and follow the information and instructions
on handling diamond dry-cutting discs (see
page 22).
13 If the feed is too fast, the red LED (4) lights up.
Then, reduce the feed immediately until the green
LED (3) lights up again.
If this warning signal is ignored, i.e. the feed is not
reduced, the electronics switch off on overload.
DANGER
Risk of injury due to uncontrolled kickback of the
diamond cutter, caused by canting of the diamond
cutter in the cut chase.
Î Always wait for the diamond dry-cutting discs to
stop completely before removing the diamond
cutter from the cut chase.

The cutting process can then be started and contin-
ued as described above (see "Chap. 5.4 Switch on
the diamond cutter and cut").
NOTE
The diamond cutter also switches off if the
diamond dry-cutting disc has insufficient cutting
power. In this case, check whether you have
chosen the correct diamond dry-cutting disc for
the relevant area of use (see selection table for
diamond dry-cutting discs on page 22).
Note and follow the information and instructions
on handling diamond dry-cutting discs (see
page 22).
