Operation
Always check that the electrical equipment and potential
equalisation cables are undamaged, and that all acces-
sories are antistatic. Connect to a power source outside
the zone in accordance with the voltage specifi ed on the
rating plate of the machine.
Th e fi lter should be cleaned once or twice a day if the ma-
chine 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:
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 maxi-
mum negative pressure in the machine.
4. Open the door on the side 3 to 6 times. Th e 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. Th e 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 occurs at 1.5 kPa.
Service
Th e following precautions should generally be ob-
served before the start of maintenance operations:
1. To avoid the spread of dust, before the machine is
removed from the contaminated area, it must be
vacuumed and wiped clean, and the suction open-
ings should be closed with sealing means such as
plugs.
2. All machines must be regarded as being contami-
nated 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 operations,
all contaminated items that have not been cleaned
satisfactorily must be disposed of. Such items must
Th e container underneath the cyclone should be emptied
when about 2/3 full or max. 40 kg. Release the two fasten-
ers 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 fric-
tion of particles against the container. See CENELEC TR
50404 for the appropriate measures.
When the container is attached back onto the dust extrac-
tor, make sure that the bracket is properly attached to the
contact plate.
be disposed of in dustproof 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 fi ltered
forced ventilation.
6. Clean the maintenance area beforehand.
7. Use suitable personal protective equipment.
8. Th e fi lter cartridge in the cyclone should be replaced
as necessary, and at least once a year. Only use an
original fi lter (order number 42024H + 42025H).
