Rotating the Machine Head

f

Before any work on the machine itself, pull the mains 

plug.

The machine head can be 

rotated with respect to 

the machine housing in 

90 °  steps. In this man-

ner, the On/Off switch 

can be brought into a 

more convenient posi-

tion for special working 

situations, e. g., for cut-

ting operations using the 

cutting guide with dust 

extraction protection 

guard 

20

 or for left-handed persons.

Completely unscrew the four screws. Rotate the machine 

head carefully, 

without removing it from the housing,

 to the 

new position. Screw in and tighten the four screws again.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing coatings, 

some wood types, minerals and metal can be harmful to 

one’s health. Touching or breathing-in the dusts can cause 

allergic reactions and/or lead to respiratory infections of 

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered 

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials 

containing asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble for the material.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the 

materials to be worked.

f

Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Operation

Starting Operation

f

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.

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 

3

 forwards.

To 

lock

 the On/Off switch 

3

, press the On/Off switch 

3

 down 

at the front until it latches.
To 

switch off

 the power tool, release the On/Off switch 

3

 or, 

if it is locked, briefly push down the back of the On/Off switch 

3

 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 grind-

ing tools. 

Damaged grinding tools can burst and cause in-

juries.

When not using the power tool, switch it off in order to save 

energy.

Reduced starting current (GWS 1100 / GWS 1400)

The electronic reduced starting current limits the power con-

sumption when switching the tool on and enables operation 

from a 13 ampere fuse.

Constant Electronic Control (GWS 1100 / GWS 1400)

Constant electronic control holds the speed constant at no-

load and under load, and ensures uniform working perform-

ance.

Working Advice

f

Exercise caution when cutting slots in structural 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

After heavily straining the power tool, continue to run 

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

sory.

f

Do not touch grinding and cutting discs before they 

have cooled down. 

The discs can become very hot while 

working.

f

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

Rough Grinding

f

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.
