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.
