Dustcontrol DC 3800 H Turbo EX Notice Originale page 17

Service
The following precautions should generally
be observed before the start of maintenance
operations:
1. To avoid the spread of dust, before the ma-
chine is removed from the contaminated area,
it must be vacuumed and wiped clean, and the
suction openings should be closed with seal-
ing means such as plugs.
2. All machines must be regarded as being
contaminated if they are removed from the
hazardous zone. Appropriate measures must
be taken to prevent the spread of dust.
3. When performing maintenance or repair op-
erations, all contaminated items that have not
been cleaned satisfactorily must be disposed
of. Such items must be disposed of in dust-
proof bags in accordance with the provisions
that are applicable to the disposal of waste.
4. Clean the machine before disassembly.
5. (Wherever possible), choose a room with
filtered forced ventilation.
6. Clean the maintenance area beforehand.
7. Use suitable personal protective equipment.
8. The filter cartridge in the cyclone should be
replaced as necessary, and at least once a
year. Only use an original filter.
Part No 42024 H and 4202501 H.
9. The machine should be disconnected from
the power supply during cleaning and mainte-
nance. Service operations should never take
place in the zone area.
10. Because the DC 3800 H Turbo EX is used in
an explosive environment, the functionality of
the machine must be inspected by the manu-
facturer or a trained person at least once a
year (e.g. inspection of the filter for damage,
inspection of the air tightness of the dust-
extraction machine and function of the control
unit, and inspection of the electrical compo-
nents, seals and potential equalisation cables
for damage. Only use original spare parts.
11. To empty the dust collection container, the
two fasteners must be released with care,
one after the other, to prevent dust from being
stirred up unnecessarily. After lowering the
container, the extractor should be switched
on again in order for any suspended particles
to be sucked into the filter cyclone. The con-
tainer can now be removed from the machine.
Carefully remove the full sack from the edge of
the bin, and immediately seal it tight. Fit a new
plastic sack, and carefully pass the opening
back over the edge of the bin. Make sure that
no folds occur, and that the sack is not dam-
aged. Then carefully install the bin under the
extractor and attach the two hooks, turn off the
machine and secure the bin to the machine
once more, making sure that the retaining
hooks are positioned correctly (see diagram)
and check for leaks.
