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.
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
Servicing
If the dust extractor's suction performance decreases,
and even cleaning the filters 5 (fig. 2) after
replacement of the filter bag 8 (fig. 4) does not
increase the suction performance any more, the
folded filter cartridges 5 (fig. 2) must be renewed.
Usually it is sufficient to clean the folded filter
cartridges 5 from time to time, 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 suction cleaning 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 damages.
6.3
Motor protection filter
The folded filter cartridges are located next to the
motor protection filter 6 (fig. 2). If they are heavily
soiled, rinse out and reinsert in dry condition.
Damaged motor protection filters must be replaced.
