Protection class
The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
Assembly
 Before any work on the machine itself, pull the mains
plug.
Dust Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
Mounting/Replacing the Diamond Cutting Disc
(see figure A)
 When mounting and replacing diamond cutting discs, it
is recommended to wear protective gloves.
 Diamond cutting discs become very hot during opera-
tion; do not touch them until they have cooled down.
 Always use a correctly sized diamond cutting disc with
the fitting mounting hole that corresponds with the in-
formation listed in the technical data.
 Use only diamond-tipped cutting discs. Segmented dia-
mond wheels may only have negative cutting angles
and slots between the segments to a maximum of
10 mm.
Mounting the Diamond Cutting Disc
– Clean the diamond cutting disc 6 and all clamping parts to
be mounted.

Operation
Operating Modes
 Before any work on the machine itself, pull the mains
plug.
Pre-selecting the Cutting Depth (see figure B)
 The cutting depth may only be pre-selected when the
machine is switched off.
Adapt the cutting depth to the thickness of the workpiece. For
optimum results, the diamond cutting disc must protrude ap-
prox. 2 mm out of the material.
– Loosen wing bolt 4. For a smaller cutting depth, pull the
machine from the base plate 8; for a larger cutting depth,
push the machine toward the base plate 8. Adjust the de-
sired cutting depth at the cutting-depth scale 3. Tighten
wing bolt 4 again.
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
Switching On and Off
To save energy, only switch the power tool on when using it.
– To start the machine, press the On/Off switch 1 and keep
it pressed.
– To lock the pressed On/Off switch 1, press the lock-on
button 2.
– To switch off the machine, release the On/Off switch 1 or
when it is locked with the lock-on button 2, briefly press
the On/Off switch 1 and then release it.
 Check the diamond cutting discs before use. The dia-
mond cutting disc(s) must be mounted properly and be
able to rotate freely. Carry out a test run for at least one
minute without any load. Do not use diamond cutting
discs that are damaged, out-of-balance, or vibrate.
Damaged diamond cutting discs can rupture and lead to in-
juries.
