Dust extraction
► Dusts from materials such as lead-containing
coatings, some wood types, minerals and metal can
be harmful to one's health. Touching or inhaling
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 consi
dered carcinogenic, especially in connection with
wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked on by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work area.
– The use of a P2 filter class respirator is recom-
mended.
Observe the relevant regulations in your country for
the materials to be worked.
The vacuum cleaner must be approved for
the extraction of masonry dust. WOLFF provides:
STARVAC MI55 wet and dry vacuum cleaner
#60800
Insert the suction hose of the vacuum
cleaner in the adapter (12) of the machine.
Information for the Use of
Screed grooving machine
► Please observe the following notes in order to
reduce the dust emissions occurring while working.
– Use only the combinations of Screed grooving
machine and dust-category M vacuum cleaner
recommended by WOLFF. Other combinations
can lead to insufficient dust collection and
separation.
– Observe the operating instructions of the vacuum
cleaner for maintenance and cleaning of the
vacuum cleaner, including the filter.Empty dust
collection containers immediately once full. Clean
the filters of the vacuum cleaner regularly and
always insert the filters completely into the
vacuum cleaner.

– Only use vacuum hoses as intended for
by WOLFF. Do not manipulate the vacuum hose.
When rocks or chunks of stone/masonry are
drawn into the vacuum hose, cease work and
clean the vacuum hose immediately. Prevent the
vacuum hose from being bent or creased.
– Use the wall chaser only according to its intended
use.
– Only use tools that are in perfect condition.
Decrease in work progress is noticeable whilst
using worn tools.
– Observe the general requirements for construction
sites.
– Provide for good ventilation.
– Ensure that the working range/area is free
of obstructions. For longer slots, the vacuum
cleaner must be guided along in time, without
obstructions in the path.
– Wear hearing protection, protective goggles, dust
mask and gloves as required. As dust mask, use
at least a particle-filtering class FFP 2 half-mask.
– Use a suitable vacuum cleaner for cleaning
the workplace. Prevent settled dust from being
swirled up by sweeping.
