Operation

Starting Operation

f 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.

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.

f 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.

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

f Exercise caution when cutting slots in struc-

tural walls; see Section “

Information on

Structures

”.

f Clamp the workpiece if it does not remain

stationary due to its own weight.

f Do not strain the machine so heavily that it

comes to a standstill.

f Grinding and cutting discs become very hot

while working; do not touch until they have

cooled.

Rough Grinding

f 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.

Flap Disc

With the flap disc (accessory), curved surfaces and

profiles can be worked.

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.
