Operating instructions

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 21 and auxiliary handle 4 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 operator.
Speed preselection (GWS 7-115ET)

the thumbwheel 22 (also while running).
