Approved Grinding Tools
All grinding tools mentioned in these operating
instructions can be used.
The permissible speed [rpm] or the circumfer-
ential speed [m/s] of the grinding tools used
must at least match the values given in the table.
Therefore, observe the permissible
rotation-
al/circumferential speed
on the label of the
grinding tool.
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, 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

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
grinding tools.
Damaged grinding tools can
burst and cause injuries.
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
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
