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 Care
If the dust extractor's suction power decreases and if
even cleaning the filter 5 (fig. 2) after replacement of
the paper filter bag 8 (fig. 4) does not increase the
suction power any more, the folded filter cartridges 5
(fig. 2) need to be replaced.
As a rule, it is sufficient to every now and then clean
the folded filter cartridges 5 using a soft brush and
water. Allow to dry before reinserting, to prevent the
dust from clinging to the moist filter.
To avoid heavy soiling of container and filter, remove
dry material from the container before vacuuming
liquids. Dry vacuuming only with completely dried-out
device. Do not clean container and accessories with
abrasive commercial detergents.
Regularly clean the water sensors 13 (Fig. 3) and
check them for possible damage.
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
compliance with the valid regulations for the disposal
of such waste.
6.2 Motor protection filter
The motor protection filters 6 (fig. 2) are located next
to the folded filter cartridges. If they are heavily
soiled, rinse out and reinsert in dry condition.
Damaged motor protection filters must be replaced.
7 Disposal information
-
Filter bags,
filled with normal domestic dirt are
disposed of with the normal domestic waste.
-
Filter bags,
filled with hazardous waste:
Enquire at your municipality or at the responsible
authority.
-
If necessary, the folded filter cartridge
is
disposed of in a polyester bag as hazardous
waste.
8 Troubleshooting
Danger
Determining the causes for existing
defects and eliminating these
always requires increased attention
and caution. Pull the mains plug
beforehand!
A reduction of the suction power may have various
causes:
-
Container or filter bags 8 (fig. 4) must be emptied,
cleaned or replaced.
-
Folded filters 5 (fig. 2) are heavily soiled. Clean as
described in section 5.1. After longer use and
frequent cleaning, the filters' permeability may
have reduced to such an extent that they should
be replaced.
-
Motor protection filter 6 heavily soiled.
-
Extraction hose clogged.
If the reduced suction power cannot be attributed to
any of the above-mentioned causes, do not intervene
with the device any further. Inappropriate intervention
may impair the electrical safety.
Take the device to a MAFELL customer service shop.
