Dust/Chip Extraction

Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– 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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged

ing.
Cutting metal
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
The power tool must always work in an up-grinding motion.
Otherwise there is a risk that it will be pushed uncontrolled
out of the cut.
For best results when cutting profiles and rectangular
tubing, start at the smallest cross section.
Information on structural design
Slots in load-bearing walls are subject to DIN 1053 part 1 or
country-specific regulations. These regulations must be ob-
served under all circumstances. Seek advice from the re-
sponsible structural engineer, architect or construction su-
pervisor before starting work.
Cutting aid (see figure E)
The cutting aid (14) allows you to make a precise cut when
separating materials. Ensure that the cutting aid (14) is
firmly engaged before making the cut. To do this, turn the
cutting aid (14) together with the hood (7) so that the snap-
in fin (17) engages in the recess (16).
Transportation cover (see figure F)
Fit the transportation cover (13) to transport the power
tool. This serves to prevent injuries and damage.
