Intended use

The diamond cutters listed in this instruction manual
are only approved for dry cutting in masonry (brick,
lime-sand blocks, undressed stone) and concrete.
They must not be used for wet cutting or for cuts in
metal, glass, wood, etc.
•
Observe the relevant regulations in your
country for the materials to be machined.
•
The diamond cutters are only approved for
use together with a dust extractor, which is
suitable for stone dust (e.g. BAIER Special Dust
Extractor).
WARNING
Risk of injury due to cracking and breaking of
the diamond dry-cutting disc (bits of disc flying
around).
Î Diamond dry-cutting discs are designed for
straight cuts.
If used to cut curves the diamond dry-cutting
disc becomes deformed which causes internal
cracks and segments to break off.
•
Do not expose diamond dry-cutting discs to
lateral pressure.
•
Never use diamond dry-cutting discs for rough
grinding.

Before Starting Work

To ensure safe working with the diamond cutter, the
following points must be observed before each use:
•
Read through all safety instructions and
warnings in this instruction manual.
•
Wear protective clothing such as hard hat,
hearing protection or safety goggles, safety
gloves and if necessary an apron.
•
The voltage on the rating plate must be identical
with the mains voltage.
•
Before using the machine, always check the
connection cable and plug.
•
Connect a suitable dust extractor (e.g. BAIER
special dust extractor).
WARNING
Risk of injury due to cracking and breaking of the
diamond dry-cutting discs.
Î Only use diamond dry-cutting discs whose
allowable speed is at least as high as the
highest no-load speed of the diamond cutter,
and follow the manufacturer's instructions on
fitting and using the diamond dry-cutting discs.
•
Only use the diamond dry-cutting discs
recommended by Maschinenfabrik OTTO
BAIER GmbH for the respective use (see
selection table with recommended uses on

•
Only use diamond dry-cutting discs approved for
dual cutting.
•
Note and follow the information and instructions
on handling diamond dry-cutting discs (see
page 22).
•
Always note the dimension of the diamond dry-
cutting discs. The hole diameter must tightly
fit on the drive shaft (Ø 22.2 mm) without any
clearance.
•
Do not use reducers or adaptors to fit the
diamond dry-cutting discs.
•
Before starting work, check the diamond dry-
cutting discs for perfect fit and check that they
are properly fastened.

Operation and Control

5.1 Fit or replace diamond dry-
cutting discs
If the diamond cutter is used with two or several
diamond dry-cutting discs they should be swapped
over occasionally to ensure uniform wear. Unevenly
worn diamond dry-cutting discs should not be used
together.
The diamond cutter can also be used with only one
diamond dry-cutting disc.
