Dust Extraction via Suction Head
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.
– As far as possible, use a dust extraction
system suitable for the material.
– 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.
Insert the vacuum hose 18 of an all-purpose vac-
uum cleaner (accessory) into the vacuum con-
nection 17 on the suction head.
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.
Before beginning work, consult the struc-
tural engineer, architect or construction su-
pervisor in charge. Only cut through rein-
forcements with the permission of a
structural engineer.
When core drilling through walls or floors,
ensure to check the respective rooms/en-
closures for obstructions. Barrier off the
construction site and secure the drilled out
core against falling down with the use of
casing or similar.
