Constant Electronic Control
(GWS 8-100 C, GWS 8-100 CE,
GWS 8-115 C, GWS 8-125 C,
GWS 8-125 CE)
Constant electronic control holds the speed con-
stant at no-load and under load, and ensures uni-
form working performance.
Speed Preselection (GWS 6-100 E,
GWS 6-115 E, GWS 8-100 CE,
GWS 8-115 CE, GWS 8-125 CE)
Preselect the required speed using the thumb
wheel 1 according to the table following the sec-
tion "Tool Specifications" (reference values).
Operating Instructions
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not strain the machine so heavily that it
comes to a standstill.
Grinding and cutting discs become very
hot while working; do not touch until they
have cooled.
Rough Grinding
The best roughing results are
achieved when setting the machine
at an angle of 30° to 40°. Move the
machine back and forth with mod-
erate pressure. In this manner, the
workpiece will not become too hot,
does not discolour and no grooves
are formed.
Never use a cutting disc for roughing.
Flap Disc
With the flap disc (accessory), curved surfaces
and profiles (contour sanding) can be worked.
Flap discs have a considerably higher service life
than sanding sheets, lower noise level and lower
sanding temperatures.
Cutting
When cutting, do not press, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.

When cutting profiles and square pipes, it is best
to start with the smallest cross section.
Rotating the Machine Head
Before any work on the machine itself, pull
the mains plug.
guide/cutting grinder stand (accessory) or for
left-handed persons.
Unscrew completely the four screws.
Rotate the machine head carefully and without
removing 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 insulation of the machine can be
degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the venti-
lation slots and installing a residual current
device (RCD).

The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
The machine head
can be rotated with
respect to the ma-
chine housing in 90°
steps. In this manner,
the On/Off switch
can be brought to an
advantageous han-
dling position for spe-
cial working situa-
tions, e. g., for cutting
work with the cutting
