Cutting Stone
The machine must be used only for dry cut-
ting/grinding.
The machine must be operated only with dust extrac-
tion. Suitable vacs are available from Würth. In addi-
tion, wear a dust mask.
For cutting especially hard material, e. g., concrete with
high gravel content, the diamond cutting disc can over-
heat and become damaged as a result. This is indicated
clearly by a ring of sparks that rotates with the diamond
cutting disc.
In this case, interrupt the cutting process and allow the
diamond cutting disc to cool by running frely at no-load
speed for a short time.
Noticeable decreasing work progress and a rotating
spark ring are indications of a diamond cutting disc that
has become dull. With brief cuts in an abrasive material
(e. g., chalky sand stone), it can be sharpened again.

Important is the direc-
tion in which cutting is
performed.
The machine must al-
ways work opposite to
the direction of rotation.
Therefore, never move
the machine in the other
direction!
Otherwise,
the danger exists of it
being pushed uncon-
trolled out of the cut.
It is best to work with a
diamond cutting disc. To
ensure against tilting,
the cutting guide with
special protective vacu-
uming hood must be
used.
Switch on the machine
and place the front part
of the cutting guide on
the workpiece.
Slide the machine with
moderate
advancing
that is adapted to the
material to be worked
(Figure).
Rotating the Machine Head
Before any work on the machine itself, pull the
mains plug.
Unscrew completely the four screws.
Rotate the machine head carefully and without remov-
ing from the housing to the new position.
Screw in the screws again and tighten.
Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and the ventilation slots clean.
In extreme working conditions, conductive dust
can accumulate in the interior of the machine
when working with metal. The protective insula-
tion of the machine can be degraded. The use of a sta-
tionary extraction system is recommended in such cases
as well as frequently blowing out the ventilation slots
and installing a residual current device (RCD).
If the machine should happen to fail despite the care
taken in manufacture and testing, repair should be
carried out by an authorized customer service agent
for Würth power tools.
For all correspondence and spare parts orders,
always include the article number on the type plate
of the machine.
For the current spare parts list of this machine, log
into the Internet under "http://www.wuerth.com/

Würth branch office.
The machine head can
be rotated with respect
to the machine housing
in 90° steps. In this
manner,
the
on/off
switch can be brought to
an advantageous han-
dling position for spe-
cial working situations,
e. g., for cutting work
with the cutting guide/
cut-off stand (optional
extra) or for left-handed
persons.
