Danger
While the dust extractor motor is
coasting down, the operating mode
selection switch may not be turned
until the dust extractor has come to
a standstill, otherwise the device
must afterwards be switched via
the 0-position to guarantee the
perfect functioning of the electronic
system.
5.2 Hints and information
-
When vacuuming dry materials, the folded filter 5
(fig. 2) must be completely dry.
-
During wet vacuuming, the built-in sensor prevents
the maximum filling level in the container from
being exceeded. The device no longer vacuums
when the container is full. Switch off motor. Pull the
dust extractor plug and empty the container.
-
If the sensor responds when vacuuming larger
amounts of liquid (more than one container filling),
switch off the device and empty the container.
-
If the volume flow display 3 (fig. 1) lights up on
restart, this may have the following reasons:
-
Container, filter bag 8 (fig. 4) full.
-
Extraction hose clogged.
-
Air cross sections of the dust generator too
small.
On completion of work, but especially if you do not
intend to use the device for a longer period of time,
you should:
-
Discharge any dirt and liquids.
-
Store the extraction hose such that there are no
kinks.
-
Neatly reel up the mains cable and protect it
against damage.
6 Service and maintenance
Danger
Pull the power plug during all
service work.
After longer periods of operation,
MAFELL recommends to take the
device to an authorised MAFELL
customer service shop for
inspection.
The storage place must be dry and frost-protected.
If the device fails despite diligent manufacturing and
test procedures, the repair must be carried out by an
authorised customer service station for MAFELL
products.
Danger
Only use MAFELL accessories and
spare parts. Have components, the
replacement of which has not been
described in this document,
replaced at a MAFELL customer
service station.
6.1 Maintenance
For maintenance by the user, the device must be
disassembled, cleaned and serviced as far as this is
feasible without causing any danger for the
maintenance personnel and other persons. Suitable
precautions include cleaning before disassembly,
providing for locally filtered forced venting at the place
where the device is disassembled, cleaning the
maintenance area and suitable personal protective
clothing.
On machines class M, the outside of the machine
should be cleaned by means of dust extraction
methods and wiped clean or should be treated with
sealant before they are removed from the hazardous
area.
All machine parts must be considered contaminated if
they are removed from the hazardous area and
suitable action must be taken to avoid the dust from
being dispersed. Such objects must be disposed of in
impervious bags in compliance with the valid
regulations for the disposal of such waste.
The method to be applied when removing covers for
cleaning purposes from areas that are not dust-tight
should also be specified in the operating manual.
When carrying out maintenance or repair work, all
soiled objects which cannot be cleaned in a
satisfactory manner must be disposed of. Such
objects must be disposed of in impervious bags in
