Operation

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.

 Hold power tool by insulated gripping surfaces 21 and

auxiliary handle 3 only. The accessory may contact hid-

den wiring or its own cord. Accessory contacting a “live”

wire may make exposed metal parts of the power tool “live”

and shock the operator.

When operating the machine with power from mobile genera-

tors that do not have sufficient reserve capacity or are not

equipped with suitable voltage control with starting current

amplification, loss of performance or untypical behavior can

occur upon switching on.

Please observe the suitability of the power generator being

used, particularly with regard to the mains voltage and fre-

quency.

Switching On and Off

To start the power tool, push the On/Off switch 2 forwards.

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.

 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 grind-

ing tools. Damaged grinding tools can burst and cause in-

juries.

To save energy, only switch the power tool on when using it.

Kickback stop (GWS 750-100 I)

In case of a sudden drop in speed, e.g.,

caused by a jammed disc while cutting, the

power supply to the motor is electronically

interrupted.

To restart the operation, switch the On/

Off switch 2 to the Off position and start the

machine again.

Restarting Protection (GWS 700/GWS 710(115)/

GWS 750/GWS 750-100 I)

The restarting protection feature prevents uncontrolled re-

starting of the machine after an interruption in the power sup-

ply.

To restart the operation, switch the On/Off switch 2 to the

Off position and start the machine again.

Reduced starting current (GWS 750-100 I)

The electronic reduced starting current limits the power con-

sumption when switching the tool on and enables operation

from a 13 ampere fuse.

Working Advice

 Before any work on the machine itself, pull the mains

plug.

 Exercise caution when cutting slots in structural walls;

see Section “Information on 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.

 After heavily straining the power tool, continue to run

it at no-load for several minutes to cool down the acces-

sory.

 Do not touch grinding and cutting discs before they

have cooled down. The discs can become very hot while

working.

 Do not use the power tool with a cut-off stand.

Rough Grinding

 Never use a cutting disc for roughing.

The best roughing results are achieved when setting the ma-

chine 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 Metal

 For cutting with bonded abrasives, always use the pro-

tection guard for cutting 14.

When cutting, work with moderate feed, adapted to the mate-

rial 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 ap-

plying sideward pressure.

The machine must al-

ways work in an up-

grinding motion. Other-

wise, the danger exists

of it being pushed un-

controlled out of the

cut.

When cutting profiles and square bar, it is best to start at the

smallest cross section.
