Dust/Chip Extraction
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.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Speed preselection
The required speed can be preselected with the thumbwheel 4 (also while running).
The data in the following table are recommended values.

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.

When operating the machine with power from mobile genera-
tors that do not have sufficient reserve capacity or are not
– 11000 80
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-
11000 45
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.
Constant Electronic Control
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.

Cutting disc and cutting guide (Cutting masonry/stone is
permitted only with use of the cutting guide)
Rough Grinding
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.
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.

After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
Grinding and cutting discs become very hot while
working; do not touch until they have cooled.
Do not use the power tool with a cut-off stand.
Never use a cutting disc for roughing.
