Dust/Chip Extraction

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

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 switch off the machine, release the On/Off
switch 15.
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

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, con-
tinue to run it at no-load for several minutes
to cool down the cutting/grinding tool.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Cutting Metal
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.
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
