Dust Extraction via Suction Head

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.

– 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

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.

f 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.

f 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.
