Service
9. Th e machine should be disconnected from the power
supply during cleaning and maintenance. Service
operations should never take place in the zone area.
10. Because the DC 3800/5800 H Turbo EX is used in
an explosive environment, the functionality of the
machine must be inspected by the manufacturer or a
trained person at least once a year (e.g. inspection of
the fi lter for damage, inspection of the air tightness
of the dust-extraction machine and function of the
control unit, and inspection of the electrical com-
ponents, seals and potential equalisation cables for
damage. Only use original spare parts.
11. To empty the dust collection container, the two fas-
teners 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 parti-
cles to be sucked into the fi lter cyclone. Th e contain-
er 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 damaged. Th en carefully put the container
back in place, attach the two fasteners, switch off the
machine, and re-attach the container to the machine
and check that there are no leaks.
Filter replacement
Th e fi ne fi lter should be replaced at least once a year.
HEPA fi lters should be replaced after every 300 hours of
operation. Wear a dust mask when replacing the fi lter.
Only use an original fi lter.
Release and lift off the lid. To prevent the escape of dust,
place a plastic sack over the cyclone, and remove the fi lter
cartridge. Clean the fi lter plate. Th en fi t the new fi lter.
- CAUTION! Do not reuse the main fi lter once it has
been removed from the machine.
Th e HEPA fi lter is removed by withdrawing the cartridge
after opening the lid. Th e new fi lter cartridge is placed in
the fi ne fi lter and is sealed by carefully attaching the lid.
Caution
Th e manufacturer or a trained person must carry out an
inspection at least annually, e.g. damage to the fi lter, air-
tightness of the dust-extraction machine and the function
of the control unit.
Th e turbopump has a very long service life and requires no
maintenance. After approximately 10,000 hours of opera-
tion, the radial seal between the motor and the pump
should be lubricated with bearing grease. Th e bearings
and seals of the electric motor must be inspected at the
same time. Th ese must be lubricated and replaced, if

necessary. If any other wear is observed, the parts con-
cerned must be replaced.
