Dust/chip extraction

Dusts from materials such as lead-contain-
ing 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-treatment addi-
tives (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 coun-
try 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.
Hold power tool by insulated gripping sur-
faces 2 and auxiliary handle 5 and 6 only.
The accessory may contact hidden wiring
or its own cord. Accessory contacting a
"live" wire may make exposed metal parts of
the power tool "live" and shock the opera-
tor.
When operating the machine with power from
mobile generators that do not have sufficient
reserve capacity or are not equipped with suit-
able voltage control with starting current ampli-
fication, 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 4 , 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.

Working advice

Exercise caution when cutting slots in
structural walls; see Section "Informa-
tion 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 min-
utes to cool down the cutting/grinding tool.
Sanding discs become very hot while
working; do not touch until they have
cooled.
Do not use the power tool with a cut-off
stand.
Information on Structures
Slots in structural walls are subject to the Stan-
dard DIN 1053 Part 1, or country-specific regu-
lations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architect
or the construction supervisor.
