This Standard covers the safety of dust ex-
tractors with electric motors, including dust
separators and back-pack vacuums, used for
wet extraction, dry extraction, or wet-and-dry
extraction, supplied for commercial use indoors
Always check that the electrical equipment and
potential equalisation cables are undamaged,
and that all accessories are antistatic. Connect to
a power source outside the zone in accordance
with the voltage speci
fi
ed on the rating plate of the
machine.
The
fi
lter should be cleaned once or twice a day if the
machine is operated continuously or, if the machine
is equipped with a pressure gauge and the needle
is in the red zone.
To clean the
fi
lter:
DC 3800 H Turbo EX
1. Start the machine.
2. Disconnect the hose from the suction casing.
3. Close the suction hose tightly, e.g. by pressing
it against the
fl
oor. Closing the hose produces
maximum negative pressure in the machine.
4. Open the door on the side 3 to 6 times. The air
rushes into the machine and cleans the
fi
lter
by means of reverse pulse.
5. Open the hose again, and reconnect the
suction nozzle.
6. If the pressure gauge needle is in the green
zone, work can continue. If it is in the red
zone, repeat the reverse pulse cleaning. If the
presusure gauge needle remains in the red
zone after reverse pulse cleaning has been
performed several times, the
fi
ne
fi
lter (part no. 42398)
should be changed.
Some operations (i.e. those that that restrict air
fl
ow)
can make the pressure gauge show a high reading,
even when the
fi
lter is clean. The machine should
never be operated permanently when the gauge is
in the red zone, as this poses a risk of overheating.
Transition from the green area to the red area oc-
curs at 1.5 kPa.
The container underneath the cyclone should be
emptied when about 2/3 full or max. 40 kg. Release
the two fasteners and remove the container. Be
careful when releasing the fasteners, as they can
open with great force, especially when the material
is heavy. Be aware that emptying the container may
pose a risk of explosion, i.e. an explosive atmosphere
may occur and a static charge may be generated by
the friction of particles against the container. See
CENELEC TR 50404 for the appropriate measures.
When the container is attached back onto the dust
extractor, make sure that the bracket is properly at-
tached to the contact plate.
Operation
ATEX
The machine and accessories are suitable for use in
Zone 22 (2014/34/EU) for the suction and removal of:
and for outdoor use with and without accessories, in order
to collect combustible dust in an atmosphere (Zone 22)
designated as explosive.
CAUTION!
This machine contains hazardous dust. Empty-
ing and any maintenance operations, including
the removal of dust collection containers, must
only be carried out by specialist personnel, who
must wear the appropriate protective equipment.
Do not operate without the complete
fi
ltration system.
