Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power 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.
Switching On and Off
To start the power tool, push the On/Off switch 2 for-
wards.
To lock the On/Off switch 2, press the On/Off switch
2 down at the front until it latches.
Speed preselection (GWS 6-115 E / GWS 850 CE)
The required speed can be preselected with the thumbwheel 3 (also while running).
The data in the following table are recommended values.

Operating Instructions
Exercise caution when cutting slots in struc-
tural walls; see Section "
Structures
".
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
Never use a cutting disc for roughing.
The best roughing results are achieved when setting
the machine at an angle of 30° to 40°. Move the
machine back and forth with moderate pressure. In
this manner, the workpiece will not become too hot,
does not discolour and no grooves are formed.

To switch off the power tool, release the On/Off
switch 2 or, if it is locked, briefly push down the back
of the On/Off switch 2 and then release it.
Check grinding tools before using. The
grinding tool must be mounted properly and
be able to move freely. Carry out a test run
for at least one minute with no load. Do not
use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Constant Electronic Control
(GWS 850 C / GWS 850 CE)
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform work-
ing performance.

Flap Disc
With the flap disc (accessory), curved surfaces and
profiles can be worked.
Information on
Flap discs have a considerably higher service life,
lower noise levels and lower sanding temperatures
than conventional sanding sheets.
Cutting
When cutting, work with moderate feed, adapted to
the material being cut. Do not exert pressure onto the
cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.

The machine must
always work in an up-
grinding motion. Oth-
erwise, the danger
exists of it being
pushed uncon-
trolled out of the cut.
When cutting profiles
and square bar, it is
best to start at the
smallest cross sec-
tion.
