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. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are 
considered as carcinogenic, especially in 
connection with wood-treatment additives 
(chromate, wood preservative). Materials 
containing asbestos may only be worked by 
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your 
country for the materials to be worked.

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.

When operating the machine with power from 
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable 
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior 
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to 
the mains voltage and frequency.

Switching On and Off

To 

start

 the power tool, press the On/Off switch 

15

 forward and then down.

To 

lock-on

 the pressed On/Off switch 

15

, push 

the On/Off switch 

15

 further forward.

To 

switch off

 the power tool, release the On/Off 

switch 

15

, or when it is locked, briefly press the 

On/Off switch 

15

 and then release it.

Switch Version without Lock-on 
(country-specific):

To 

start

 the power tool, press the On/Off switch 

15

 forward and then down.

To switch off the machine, 

release

 the On/Off 

switch 

15

.

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.

Reduced starting current (GWS 24-300 J)

The electronic reduced starting current limits 
the power consumption when switching the tool 
on and enables operation from a 13 ampere 
fuse.

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, con-
tinue to run it at no-load for several minutes 
to cool down the cutting/grinding tool.

f

Grinding and cutting discs become very hot 
while working; do not touch until they have 
cooled.

Cutting Metal

f

For cutting metal, always work with the pro-
tection guard for cutting 5.

When cutting, work with moderate feed, adapt-
ed to the material being cut. Do not exert pres-
sure onto the cutting disc, tilt or oscillate the 
machine.
